Cypher 3D - Love this Heli!

[maddog57]

James, you're doing better than I. I'm not yet accomplished at hovering! So far haven't been able to keep 'er in the air for more than 5 sec. before i need to put it down, or else I totally lose it and she hits the dirt

Chris

[irjamesm]

But thats about all i'm doing, too afraid to try something more daring

HEY Globs, I'm looking at the HXT900's at Hobby King. They list 2, one for $4.99 and one for $3.65. The specs seem to be the same. Any idea what's up there? Also they say " Our HXT500 and HXT900 are export only, and not built for the domestic market." What does that mean?

thanks, Chris

Man...I can kick some butt on the sim, totally different with the Cypher. It's that "pucker factor" that gets me.:YeaBaby:

I'm 99% sure mine is set-up right. I just need more sim time and more real air time.

Chris

[irjamesm]

I had a fixed pitch heli for about a year, didnt fly very well but it helped. It's all very small inputs........

James

[Globs]

Yes I use the GY401 on mine too.
Can't recall the settings offhand but 72% gain on the DX7 and delay on the gyro set very low or zero.

I set it up to be about right on rate-setting (by sliding servo up and down boom) and it holds the tail pretty well. The 8mm lever on the servo is small bu the servo is fast and the resolution and torque are helped by that.

I do suspect 450 batman tail blades would hold better (or a higher headspeed, mine just drifts around and I get a 10 minute flight time from a cheap 2200mAh 25C Mystery.

[blvdbuzzard]

James here is the servo:
http://www.allerc.com/product_info.php?cPath=40&products_id=3864

It is a fast digital servo that works well with the G401B and the GY401.

Chris, I too am just as good as any 3D contest person on the sim. I get out in the real world and see the dollar signs flying around and know I can not replace it right away, I chicken out. So I am over come by the pucker factor.

The Hobby People sale is between April 15th and the 20th. I may pick up another Cypher just for parts stock. I am tempted to get another RDS8000 for $200.00 and then sell the Tx for $100.00 and keep the Rx's. That would make them $50.00 a piece. Better then $80.00 a piece now.

They are going to have the Impulse brand 2200 nah 3S lipo on sale for $34.00. Not a bad price. The ones I got from China cost me $26.00 a piece after shipping. That is close to the same cost and I can get them NOW!!!. They will be selling the Futaba GY401 for $130.00 without servo. They also have the Airtronics 94761 digital servo on sale for $45.00, not cheap but a dang good servo. I have that servo in my MX450SX with the GY401. No movement from the tail. Rock freakin solid. The HS-55's are $10.00. Spend the extra dollar and get the 94091's for $11.00

I work with a guy who works at a Hobby People store and a customer wants help setting up his Cypher. I will be spending time with a new convert and see if I can increase the hold of this obsession we cal Cypher. Not sure about the radio though. It is a DX5? or a DX6. I know it is not the 6i, it had only 3 point curves.

I did get to fly this past weekend. I was hovering about 20 feet up and did a nice back flip. My brother in laws and brother freaked out. They thought I lost it. I did a couple rolls, more back flips and a forward flip. I then did a back flip until the nose is pointed straight down, let it fall some and then did a pull out into FF flight then a stall turn back. Then I did some hovering side in then the other then a little nose in. Still not good with nose in. Still need more time. Then hit throttle hold and did a short auto. These little birds do not hold the energy likek my 30 sized nitro helicopters do.

Had fun got some flights and still flyable. So it is all good stuff.

Hey dru, thanks for the link. The speed on that is about half from what i have on mine.Allthough for what i'm doing the hi-tec one holds pretty good....I do get a little drift (Clockwise).I'm not real sure on how the gyro/TX should be set up ,but i got he wag out. Anyone here in so cal going to RCX Show in Pomona? I did get a sim, i got the FSONE for only $99.99 at Hobbytown. Couldnt afford the realflight G4.5 at twice the price. But yea the sim is a bit easier than "The Real Thing" but it does help, I can do some flips and suff on it....could see doing with my Cyph though....

Sorry only just noticed this post.
Domestic servos are of lower quality and will have cheaper plastic in the gears etc., apparently. Not sure why there is a price difference. If you buy some from there get some spare gears as they are only 99c a set and weigh nothing.

I managed to break an HXT900 gear set - but I had to try really really hard three times to do it :)

Just finish building cypher, cant get tail gyro to move. need help:arggg:

[Globs]

After my spectacular high impact crash the other day the bird is all back together again. The last change was the left hand main frame side and landing subframe.

This time I fixed it I decided (as I've now got a pitch gauge!) to play about with the servo endpoints and make the pitch range (0 - 100 on the DX7) to +10 degrees, 0, -10 degrees. I also removed the flybar weights that I'd had on there. Well I just didn't put them onto the new flybar in fact!

I was going to put the H50a ESC on it too but in the end it was easier to refit the old one as it is smaller and just perches in front of the mainshaft right on top really nicely (heatsink up with caps towards the shaft, single tyrap, RX lead across the top of the LHS frame.

This made it a bit more frisky in the air than I was used to so I dialled in 70% rates and left the 30% expo there which calmed it down a bit. I'll have another go tomorrow if the wind is not bad, I've not flown this for 3 weeks as spares took ages to get..

[maddog57]

Globs, not a problem on the delayed answer, didn't expect one the same day. We're all busy! i think I may try the Airtronics 94091's for my cyclic. Dru says they're pretty good and they're fairly cheap.I love the 65's, they're like a tank! Didn't like the fact I had to mod the frame to get 'em in.we 'll see.

The gyro isn't supposed to move, just leave it stuck down and it will be fine :thumbup:

[heli-c]

...Then I noticed when the canopy is on, it's REAL close to those two servo arms. There is, I think [it's hard to see], enough clearence... just wanted you guys that are using the 65's to be aware and check for clearence.

Chris

Just wanted to say thanks for highlighting this; I haven't had the time (or weather) to maiden my Cypher yet but on checking the clearance I found that the pushrods graze the canopy on max. positive pitch :noteworthy

Looks like the Cypher following is gaining momentum...:) maybe we should start to put an EF Cypher bible together? I'm going to scan and PDF the instruction manual to get things rollling...

Cheers

[blvdbuzzard]

Broklyn, need more info. What is not moving, the servo or is it not moving when you move the helicopter?

Red lead plugged into gain channel, on mine it is channel 5 on the Rx. So the single yellow wire goes into channel 5, the black plug goes into the rudder channel, servo plugged into lead on gyro. I am not versed in the ways of the DX7. Others will have to help you there.

Chris, I love my HS65MG's. I have them in my Diablo. Great servos. The 94091 work better in the Cypher. Lither and cheaper. I always worry about planting my Diablo. That would cost a bit more then the Cypher. I am trying to keep the costs down amd an $11.00 servo is cheaper to replace then the gear set in the HS65MG.

Globs, keep the rates the same and turn up the expo. I am running about 40% in normal mode and 15% in idle up. It makes it pretty calm in a hover in normal mode.

[skypup]

I got my new Cypher yesterday. Was just playing with the the swash and noticed that it was a little tight moving up and down on the main shaft. Has this been normal for most? It's definitely not silky smooth the way I like it.

[skypup]

Has the 2 amp bec on the stock esc been adequate to run all servos including a digital tail servo? Thanks in advance. I normally run a seperate bec but was curious to save weight.

[Globs]

Not sure about the shaft - I recall someone sanding it lightly so you could try that?

I run 3 HXT900s and a digital DS09-GMD and it all works. The ESC does get quite hot though - some of that heat is from the BEC as it heats up a bit even with no motor running.

ETA: It also runs the GY401 and AR6200 RX of course!

I have stripped off the top plastic and mount my ESC right on the top just in front of the main shaft (heatsink up, capacitors to the back) with a tyrap, so any downdraft cools it and it gets it slightly further back.

I did buy an H50a with 3A switched BEC but could not find a really neat way of mounting it, so I just stuck the old one back in as I wanted to fly it. 4 packs today, going very nicely (got some nice selected trex 450 GF blades on at the moment)..

[blvdbuzzard]

I am running (3) Airtronics 94091 servos, Logitech 2100T / 3100G digi servo. I have run a GY401 with an Airtronics 94761 digital, GY240 with analog HS-81.

I have not had an issue yet. I too have removed the shrink wrap from the ESC and it sits where the air can get to it.

She flies well for me.


Dru.

[Brooklyn Z]

i mean tail servo. sorry for the mix up.

[Globs]

i mean tail servo. sorry for the mix up.

Ah - the tail servo does not move.
You supply no other information so you need to check:



You have the (charged) battery, ESC, RX and radio system connected.
TX on, and the cyclic servos move when the radio commands them.
You are moving the rudder channel stick
Another servo works OK in the rudder channel
You have plugged the gyro into the rudder channel
You have plugged another servo into the gyro servo connector
You have plugged the tail servo into the gyro servo connector
You have tried the tail servo without the control horn on
You have connected the gyro gain up to another channel (What GYRO??)
You have tested the gyro in HH mode and rate mode (What GYRO??)
You have been wagging the helicopter side to side and checking


Please feedback and it should be easy to find the problem with the results of the above tests!

Heli-c, that sounds like a great idea! Never been involved in one, but am willing to learn and help out.

Dru, I'm gonna order a set [when the go on sale this week] of the 94091's for my other Cypher [bought it last time they were on sale for$99]. Don't like to have to mod things if I don't have to. Plus they're cheap too, that's a plus.

Man... the wind around here just will not stop!! I'm chompin' at the bit to fly.

Chris

[Vechlor]

Hi again.. I posted awhile back when the weather was good, but haven't had much time to fly my Cypher up here in the sierra foothills area. Once the weather is better, I should have more photos and videos to share on my new blog page (still being updated) http://vechlor.blogspot.com (http://vechlor.blogspot.com/)
Anyway, its good to see some new cypher-addicts :thumbup:

heli-c,
Global's website has the manual in pdf here: http://media.globalhobby.com/manual/163140.pdf

maddog57,
I have a set of Airtronics 94091z's on my cyclic, they work great and I highly recommend them.

blvdbuzzard,
I finally decided to go with 325 cf blades from hobbyking for $19.43 shipped. I haven't tried them yet, but they are near perfect in quality, balance, very cheap, but the processing/shipping time takes about 2 1/2 weeks from hong kong, then from new york to cali. http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=8396
Looks like they ran out of stock for now, negative numbers are backorders and they're even cheaper now!. Their new stock alert emailer works great, I got the first order of 350 sets, but damn they go fast! I should have bought some more. It takes them about 2-3 weeks to stock up again.

Looks like DealExtreme now carries them for $15.84 +free ship, pretty good for cf blades. http://www.dealextreme.com/details.dx/sku.20034

Brooklyn Z,
What radio/gyro/receiver/tail servo are you using? Looks like Globs has you covered!

[blvdbuzzard]

Vechlor, I am using the $13.00 Deal Extreme carbons. They are factory seconds. Mine had tiny air bubbles in the surface. One set just did not have a shinny surface. I waxed them and they look good.

The 94091 servos work great. For $11.00 you can not go wrong. I just setup an EXI for a friend of mine. He has the Eflite S75 sub micro servos. The 94091's work so much better. I had to pull the servos out and test them so I could get a set of 3 that worked at the same speed. One was slow and sticky, one was fast. Out of 5 servos, I got a good set. So I think the 94091's are a top notch servo.

The weather has been pretty poor for me too. I ended up working on my other helicopters. I have my Diablo all setup again and she is ready for a test flight. My MX450SX is ready too. I swapped out the gyro in the MX. I need the GY401 for my Raptor 30 nitro helicopter. I want to get it back in the air.

So now I have 6 helicopters ready to fly. You do know what that means, it means I can get at least 6 flights when I go to the field :O

I am glad to see this thread taking off. Iti is the ONLY one I can find that is active. The ones I have started on RCU and RCG have just died. Glad to see more people flying the Cypher.


Dru.

[Globs]

Got some GF 325 blades on at the moment, I've still got 2 pairs extra to smash up and another 3 sets of cheap woodies to mince before I order some CF blades.

I'm also working on my 'not crashing so often' strategy by using loctite and checking that the flybar mixer arm hasn't got a crack from a previous crash that may cause it to fail 50' up in the air.

I've noticed that this little heli is very quiet compared to a 'rex 450 - have you ?
Less zinging and pinging sounds - just gets into its beat and flies very nicely.
Did about 4 packs today in the garden just getting the hang of precision placing and orientations.
