Hehe! I still have to get ahold of my pitch guage. Trust me, I hope to God that the first tests go better than telling the girlfriend about the heli to begin with! It got kinda ugly!
I'm at a freind's house right now putting the final toutches on it and can't get home 'till tomarrow :arggg:

It's lookin real good right now. I put the blades on it and hand spun the blades. Smooooth! I'll definately post pics, maybe even a short vid if possible! We'll see how it turns out...the suspense is killing me :shock: :arggg:

Just read my own post, I wasn't drunk ....honest Ocifer!!

And you're still playing at 01:38am your time!!!

Look forward to seeing the Pics,

I am trying to find ways of changing the lateral balance on the Walkera it is way off to the right of the main shaft at the moment, I only started to look at this after reading the posts on Swashplate set up, and which cyclic is generally applied when lifting off a heli with a clockwise rotor. I started off with the swash square but by the time I had finished yesterday I noticed it was trimmed noticably down on the lleft, so I took off the main blades and balanced the helicopter with the Flybar parallel to the tail boom and it hung with the right skid about 1/4" low
I am going to move the Elevator servo to the other side of thr main frame and see if that helps, I already moved the receiver as far left as I can on the tray, might try moving the excess servo wires over there too!

PS

Still not using the spell checker so sorry for any mistakes

Yeah, I'm a bit of a night owl. Usually the good TV programs are over at 11pm and after that is usually my 'Freak' time! Plus I dabble around in the middle of the day. I usually end up researching different things for other people on this site to help them out, and as they learn, I learn! Win-win either way! I can't go anywhere because my truck is a standard and I lost my lower left leg in my accident, so I have to barrow a friends automatic to drive. I refuse to stay in a wheel chair most of the time, but it makes it hard to carry anything because I have to use the crutches to get around.

Good idea about the wires, and such, sometimes the little things are what count. (yet another reason helicopters are like women! Overly sensitive, twitchy and will explode at our slightest misstep! :arggg: ) :D
Where do you put your batts? You might try scootin that over a hair if you can...
Your ESC could be throwing it off a bit, see if that can be moved. Umm...that's all I can see in the pic. Whoa! those are some crazy looking push rods! Most are a piece of metal with the two ball links on the end. Never seen any like that!
That is one sexy little heli, I don't care what anyone else says!

Well, even if it doesn't fly, I'll try to get some pics in tonight. :D

Hi The battery sits in the main frame and is a tight fit, Had to turn the bolts holding the upper part of the frame to the lower around so the battery would fit, It came with a 2200mAh LiPo but that was too large and had to be attached underneath with wire ties!, so I measured the frame (because the 60B shown on the box has its battery in the main frame) then went looking at the sizes of 3 cell LiPos The largest that would fit was an 1800mAh
The Alloy head on the Walkera uses a floating flybar so there is no washout mixer on the shaft. This means that the swashplate has to be driven by the links from the mixing arms. It also means that the swash moves down to increase pitch, but overall makes for a simpler cleaner mast assembly, Oh... and it works!!

What do you mean `standard' I thought standard in the States was Automatic!! and thought it was just us old, stuck in the past Brits that drove manual shift!!
When are you being fitted for your prosthetic? and have they given you any idea what level of (for want of a better word) normality it will give you in your daily life?

I am looking forward seeing the pics. I considered the 450 after the Walkera but thought the size was too similar, really wanted something about the size of a QJ EP8 rather than something as big as the Trex 600, but in for a penny in for a pound and I bought The CF kit with motor, ESC and BEC for £279 about $540 including shipping so I am quite happy ( another £140 for Blades and a 4600mAh battery though, Oh and then updated my radio, and I needed a new Gyro, plus a servo, Oh and some better servos, and a balancer... and I still need a charger but that will have to wait)

Hmmm...Guess I've run out of ideas other than those already mentioned. I just found a new set of batteries I want to try. http://www.unitedhobbies.com/. They look pretty promising if I decie to take the leap. I can get 4, 2200mah 11.1V, 20C for a little over $130 (I think 65.97GBP) shipped!
Hey about the links, as long as they work, that's the bottom line!

'Standard' means manual shift here (or stick, 5 speed etc...). I prefer them as they are more reliable and get more power&efficiency, but a lot of people get the auto trans. For city driving, it's a ot nicer to have the auto as well.
As far as getting the new leg, I'm not too sure. I still have a tiny spot that has to heal up and then it's off to the races! They said I'll be back to surfing, skydiving, scuba divng, skiing and *Gulp!* motorcycling (if I'm crazy enough) in no-time flat once I get the prosthetic. Because it's a below knee, it only takes a little more effort to walk with a prosthetic (roughly 6% more effort). I'm excited to get it. I've never been scared of much, so the fact that I lost my leg is no biggie. My dog lost a leg in a hunting accident a couple years back and she's the happiest dog I know! We make quite a funny pair!

They are coming out with a 500 size Trex soon (I heard) if the 600 is too much. I think I'll go with one of those next if they turn out ok. I'm sure they'll be running 3Kmah packs so prices will be linear between the three birds. I was considering another gasser if I get a bigger heli. Who knows, by the time prices come down on all this electric stuff, I'll be ready to switch back over to the full size electrics!

Never been a fan of Automatics myself,

Glad to hear the good news on the leg, don't think I would have handled it as well as you have!

I have a spare 1800mAh 12c for the Walkera, but the hassle of changing the battery it's just not worth it. If I bought a couple of 1600mAh 15c then changing batteries would be a doddle, but I have spent enough at the moment, next will be a TP 1010c charger for the big LiPo and possibly a second battery, hopefully the big ones will start to drop in price soon.

Looking forward to those pics and how the running her up goes!

Me niether, but you gotta do what ya gotta do! If anyone thinks I'm in bad condition, you should see what I did to the car! :twisted:
Got my first pics up. Check out my gallery! I still have a lot to finish up on, but that should be finished soon. My goal is to get it ready to fly by Friday night at the latest. There's a guy right down the road from me that has a Trex SE as well and we are going to go fly on Saturday. I have a crappy little plane to fly if the heli starts acting up.
Oh and the pic of the ESC is the beginning of my modification. Finless recommended it in another thread and I've taken it a step further by changing out the aluminum plate with a copper plate to transfer heat better. I'll post more pics when I'm done with all that. :D

Hi
You guys drive on the right, your injury is on your left, who was on the wrong side of the road?

I watched the video on modding the heat sink on the align ESC, Those vids are really helpful, a little over the top sometimes but well worth watching, I have downloaded the ones on building the 600 and those relating to the TP 1010c charger and 210 balancer

On the mod front, I know copper conducts heat a bit better than aluminium, but either metal conducts far better than the thermal epoxy, so as there are two layers of epoxy, one between the shield and one between the shield and the heat sink / radiator either metal would transmit the heat fast enough to appear thermally transparent. Further as the heat sink / radiator is made of aluminium, were it not for the epoxy this would limit the heat transfer rate from the chips to that of aluminium, Oh and as a final thought, isn't copper a lot denser / heavier than aluminium?

Like the photo's are you going to paint the canopy? Are you spinning her up today? If so let me know how it goes, The Walkera sounds really sweet when hovering, almost silent apart from the gentle sound of the motor!!

Bought one of those X2's myself, they are great fun, Oh and I've added a few more pics, one of my `fleet', excuse the dust, but I did say They have been on shelves for years! and a couple of the original Walkera after my problems with the Electronics!

Yeah We drive on the right, I was going around a right bend in the road and my left leg got clipped by the bumper/hood of the oncoming car, yanked me off the bike onto my left side on the hood, then slid up and smashed into the windshield.

All-in-all, I broke both upper arms, my left collar bone, left thigh bone, obviously lost my left lower leg about 3-4 inches below the knee. They also had to remove my spleen and put steel rods in the broken bones, plated up my collar bone and I'm still awaiting surgery to fix the nerve damage in my left hand, I can use it but not all that well. I was "walking" after only 5 days in the hospital with a walker so I wasn't too messed up!

Yes the copper weighs a bit more, but the plates are about .040in. thinner so they barely weigh more. The reason for the plate is the IC' are at different heights. You have to put a Z-bend in it to cover the larger 2 IC's next to the leads from the battery. I'd like to use one piece for the heat sink using a solid peice of copper with fins on top and get it bent or shaped to fit the circuit so you only have 1 layer of thermal compound and the heatsink instead of sandwiching 4 layers together. But if this works out then I guess it will be ok without it!

I wanted to get some paint last time I was at the hobby shop but forgot my list and it slipped my mind. I might not be able to spin it today as my ESC kit and gyro mount haven't arrived. :arggg: I'll get everything else installed today and see if I can straighten out all the kinks if possible.

Fleet indeed! That's a pretty impressive set of helis there. Too bad they've been collecting dust for so long. Maybe you can start to use all of them in the near future after the 600 is done!

The Shuttle has been hovered on occassion, the Concept needs a horizontal stabilizer and a RX battery pack, The stork I bought and never did anything with, so really needs stripping and rebuilding before I put gear in it and run it (don't trust other peoples work, especially if they are selling it, I once bought a second hand Concept 30 from a model shop, when i got it home and checked it out properly the main gear was worn out almost totally and the guy had packed the main shaft down to keep the gear engaging on the pinion, it went straight back and Kyosho had just brought out a version with a lot of bling..... so I bought a Concept 30 SX kit, Oh, that will be the blue one in the picture

The best helicopter I have ever flown was my mates X-Cell 60, was a ***** to build, cost an absolute fortune (well out of my league) but when it was done... Oh my God What a machine!! Stable? it would hover hands off 3" off the ground!!!! ( I thought the shuttle was good it would hover hands off if you where about 5 to 6ft in the air (well clear of ground effect)) But at the end of the day MA Birds are stupid money over here (still)

That sounds like some accident, you were lucky to survive!! glad things are going the right way though!!

Watching Finless's video I thought the kinked aluminium plate was an Electromagnetic interference shield rather than part of the heat sink arrangement, his point being that the way Align attached the plate it actually acted as a thermal barrier to the heat sink allowing the components to heat up excessively

Oh and I bent the Walkera today.... Put it down and instead of bringing it back, didn't want to walk 20ft!!! tried taking off and it rolled to the left, when I got to it the back of the left skid was caught in some long grass. No major damage, I couldn;t see anything wrong so I ran it up but noticed it had a bad vibration, like when I ran it up on the table, took the blades off and found the feathering shaft was bent. Straightened it with a vice and my hand ( not very strong!!) checked it for true by rolling it on a sheet of glass and when it was straight put it back, hey Presto no more vibration or wobble!! Think I will try and source some spares though, don't fancy trusting a piece of metal that has been straightened too many times!!

I love X-cell's! The first club I went to, that's all they really flew. Most of them were .90s and a few .60's here and there. Pricey little buggers though! I don't think I've ever seen anything fly quite like the .90's, although I gotta say electrics will be much better in the near future!

I'll have to watch that vid. I just assumed it was to cover all the IC's and draw off the heat. I don't see how the aluminum would really act as an EMF shield, but who knows! I could take it out to the lab and put it on an O-Scope and a spectrum analyzer on it to see exactly what it does. Maybe sometime in the future.

Good to see durability in the little guy. At least parts are cheap! I would try X-Heli. I'm not too sure how the prices would be over there, but we get them for cheap here. You get them straight from Hong Kong there so they might be more reasonable for you!

I didn't get anywhere on mine today. :? Girlfriend worked early today and started bugging me everytime I tried even looking at the thing! I did manage to get the ESC and motor connections re-wired. I accidentally put them on backwards and did't have the stuff here to fix it right away. I got out the pitch guage too. looks like I've got +11 and -11 pitch on the blades! I had to change my end points, and I still have to adjust my links down because the stop block is contacting the head and the servos start buzzing. I'm going to have a heck of a time trying to tame all my wires! it's turned into a real rats nest back there. My Gyro has a wire lead on it almost as long as the tail boom!
Maybe i'll finish off more of it tomarrow. I hate saying that! I sound like a broken record! :?

Yeah, Girlfriends seem to have a habbit of stopping you playing, they seem to want soooo much attention, God, they're almost as bad as helicopters.

On the servo front, doesn't your radio have a Travel adjust feature? This allows you to reduce the total throw of the servo in each direction so you can still keep the ideal arm lenghth to keep the linkages straight

What did you wire wrong on the ESC, connecting the three wires to the motor on mine in any order just seemed to alter the direction of rotation of the motor ?

I do buy most of my bits for the Walkera from China/ Hong Kong / Taiwan I find them very good people to deal with as well as being excellent value. Communication can be an issue however, so trying to get the feathering shaft for the upgraded head may be a little harder, especially as Walkera refer to the Feathering Shaft as the Main Shaft and the main shaft as the Principle Axle. That caused me some trouble when I was trying to find out how to remove the Main Gear from the Main Shaft!!! ( In the end we worked it out and they explained that all you did was hit the pin with a big Hammer!!!( slight exageration)

Should be able to avoid some confusion by stating it is for the Alloy CNC head on a 60B though hopefully!!

PaulW

02-08-2007, 06:03 AM

Oh and on your T-Rex 450, if it is worth doing it is worth doing well
I don't want to start the 600 untill I have obtained some good scales to check weigh each part, rough balancing like blades on a couple of knife edges is okay on the smaller stuff but I prefer to 'do it right' on the bigger better stuff, it pays dividends in the long run!!

PaulW

02-08-2007, 07:24 AM

Just read your other post on Brushless motors, you getting tired?
Must say the motor on the Walkera has REd, Yellow and green wires coming from it, but my ESC only has three blue wires, non of which have any kind of identifying mark. The instructions for the ESC give no indication of which wire goes where either. Connecting them up left to right worked fine, swapping any two wires over caused the motor to run in reverse, sure checked out the autorotation (one way bearing ) though

:lolol Women, can't live with 'em, can't shoot 'em! hehe Just kidding!

Yeah, I had turned them down to 50% like in the vid and ended up having to go back to 60% to get the pitch right. I re-adjusted my links at 50% which brought them up and now they are touching the head. (here we go again!) I'll fix the links tomarrow and see about kicking that rat out of the back of my bird! I'd like to shorten all my leads once I get final placement figured out.

I put the male connections on the ESC and the female ends on the motor D'OH!!! :arggg: . This leaves the metal exposed on the esc if it is plugged in and the motor is unplugged which can cause a short. The shrink wrap covers the females all the way up so they don't touch. No biggie.

I'm in the baby steps stage with the build. This is when the little stuff really counts, going slow sucks, but I'll get there by Friday for sure!

I did a little research before ranting on there. I guess we just didnt see eye-to-eye. :shock: I'll take a quick pic of the ESC wires to show what I was talking about.

PaulW

02-08-2007, 08:26 AM

Do You actually fly 3D? In the 600 vids Finless sets the pitch to -11 to +11 but the manual says -9 +9 and Finless advises that for begginners so unless you are really into the 3D -9+9 would work on the 450?

See what you mean with the Bullet connectors, I didn't have that problem on the Walkera, the males were on the motor and I just transfered the females from the old ESC,

Must say my original reason for reading the Brushless thread was because my new ESC had three identical wires While the original had Red to Red Blue to Green and Black to Yellow. with the kind of currents even these little babies use I didn't fancy getting it wrong!!

Oh, and why isn't there an open season on Women, there really should be!!

02-08-2007, 08:53 AM

Actually you set up the heli like that to get it mechanically set, then n normal mode you change out your pitch curves. Same thing with Stunt 1 & 2.
-2, -1, 0, +6, +11 is the 'beginners' or NORMAL (on the mode switch) pitch curve.
Throttle curves are a little different, but it depends on how you like it.

:lolol I'm sure they feel the same way, only we deserve it more for putting up with them!

PaulW

02-08-2007, 09:42 AM

Have been setting up the Walkera purely on `feel' My pitch guage is to big for the skinny little blades, Set the bottom of the pitch curve up by eyeballing it a little negative midpoint by what looks about 4 to 5 and the top by what looks around 8 to 10
Original mechanical set up on the swash was done by setting the Radio to Acro mode, centreing the sticks and flap switch then using a vernier depth guage to measure the total travel of the swash then adjusting the servo links to hold the swash in the centre and lining the blade pitch as close to zero as i could by lining it up with the flybar. Then reset the tadio to Heli and set up the CCPM Once the swash was moving in all the right directions I ran it up, tracked the blades then played in the house for a while getting a feel for the controls. The following day I went outside setup my pitch and throttle curves by seeing how it `felt' in the hover

I have only set normal so at the moment I am ignoring the the intermediate points on the curves, let the radio work them out

Have just tried a higher head speed, with a slightly lower pitch (th75%, Pt 35%) but way too squirely for me, so now back at (Th 65% Pt 40% ) It is really suprising how much difference there is between the two settings (NB Pt 50% approx 4degrees)

That's the name of the game, but I had to start somewhere! It's like trying to solve a Sudoku puzzle. You have your known values, and rest you have to figure out on your own. You can put numbers any where you want, but one little mistake can mean one ugly outcome for the whole thing!

Hey you can make a pitch guage out of a peice of paper! The one that came with my Concept had one! I'd look it up (Unless you are more comfortable going about it the other way!).
That's one GOOD drwaback of having all these adjustments! It allows you to 'taylor' fit it to your flying needs/ability. :mrgreen:
