Los Angeles Heli flyers.

I struggled with deciding if I should use a pump too but decided I wouldn't.

My 700N is done for anyone who like to see. (Takes awhile to load)

Looks great Mike! :thumbup:

I've seen a couple guys that can fly the crap outta the 700, it's got all ya need, but do you/me/they have what it needs? :oops:

[HeliSmith]

Thanks Mitch I worked hard on it.


I can give it some love, not precision 3D, but some love... For now I am sure I will be afraid of it but that will go away.

Mike,

Beautiful work!

Really neat on the wiring (in the loom).

Nice to see the main RX treated properly (wrapped in foam).

Sure you do not want to send it to me-I will test fly it for you. I will need about a year, maybe two, with it.
You may get it back eventually.

[Lota Fun R]

Here's a question: where do you want to go with your flying?

Just being able to hover and do a few tricks isn't enough for me.

How do you plan to get there? Is practice on the sim and stick time enough?

It might be for some, but not for me, I need more.........and that's why any time I can, I get a pro to buddy box with me and critique my flying. Bert M has been helping me a lot. Matter of fact, he's the only one that has buddy boxed with me but I'll be asking others if the opportunity presents itself. :YeaBaby: I think I may need more of a coach at this point?

Yesterday Bert helped me out and mentioned he noticed such and such and I'm thinking, "no, I know how to do that" but went along with what he suggested.
I spent the day flying a box pattern backwards, I don't think I made it around even once close to perfect. So I learned a lot and I'll keep :arggg: til I get the basics down good and solid.

Sure, I can do tricks, but my trick bag runs out fast. I can fly inverted, do half arse tic tocs, some other things but I"m not satisfied with just a few tricks.

Another thing, these more seasoned competent pilots can recognize what you don't know how to do because they've been there.

First time I went out to a fun fly was an SCHC deal, I showed up with a beat up Heli Max Axe CP and a new Trex 450 that wasn't finished but was close ( I thought), couple guys promised they'd help me and they flaked out, Jim (Airboss) tried to help me with the Axe but I was a bit.......not in a good mood. :)
So, I took my Trex and TX and started walking around til I saw somebody that looked like he knew what he was doing (geenween) and asked for help, he fixed all the stuff that was wrong and Eric Stolz donated an ESC.........2 to 3 hours later my brand new Trex 450 was flying, Jason C fine tuned it. That was the coolest thing ever as far as I was concerned. :banana

Moral of the story: Don't be afraid to ask for help, and if they flake out on you, ask somebody else.

So, "where do you want to go"?

[weip98]

Yeah I wanted to ask Bert for a buddy box run too...

But he appeared really busy with someone's 90 sized bird.
So I never got to do it.

Maybe next time.

It maidened today and it flew great! Piro flipped on the maiden too! Bad Helismith.. Very BAD! Also tic tocs by the second flight but it is bogging, the power isn't there at all. I flew 4 flight and I let Jason V. fly it one flight and each time moving it in one click from 2 1/4 turns out on the main and 2 turns out on the mid. I have no clue how to tune this thing but it is still ice cold on the back plate after all those clicks.. Also it is burning 3/4 tank in 5 minutes not sure if that is right. Going to get to studying more I only know the high end needle is the master and the mid range + low are after that.

Anyway thanks for the offer though!

[HeliSmith]

Mitch I am feeling what you are feeling too. I don't fly for 2 and 3 weeks at a time lately though and I sim about as often. I can do inverted backward / forward and switch in between. I can fly normal forward and backward and of course switch in between. I can do tic tocs in any direction but not clock tic toc, I can do inverted tail first hurricanes and even toc over to vertical but my switch is too sloppy to do that one low. I do great piro flips but not good chaos. Nothing I do is precise or elegant. Oh pretty sloppy funnels too...


I have come to the conclusion that I have made tremendous progress and I have a great time flying and that is enough for me.

[emag remrofni]

Wanna let me fly it? ;)

Mike, I'm pretty sure you can go a full turn leaner from where you are now. Just turn off the governor, lean it out a turn, have your throttle curve at 100 50 100 and if it's screaming, richen it until the headspeed sounds constant or around 1800 RPM. That's a pretty good baseline and you can fine tune it from there.

[HeliSmith]

Sean you scare me when you fly YOUR helis, I know you are good but you get scary low. But I might if you promise to be cool and you catch me in the right mood.

Yeah I will get the tuning figured out I just don't understand what RPM range the mid needle comes into play or even at all if I am at top speed. I think I have the head speed a bit low too, I ran out of daylight but I just want the back plate to get warm and let the motor break in.

[emag remrofni]

Mike, I'm pretty sure the mid range is just for the transition between hover and opening up the throttle. Don't touch it unless you're having trouble warming up the back plate with the main needle.

[HeliSmith]

So close it completely? because I am seeing that as the standard procedure in the how to tune I am reading I found 3 so far all them seem to have the same basic steps.

[emag remrofni]

I never heard that you close it completely. PM Bert on runryder, he is very familiar with OS 90 engines.

[Ah Clem]

With apologies to Emag:

"Mike, I'm pretty sure you can go a full turn leaner from where you are now. Just turn off the governor, lean it out a turn, have your throttle curve at 100 50 100 and if it's screaming, richen it until the headspeed sounds constant or around 1800 RPM. That's a pretty good baseline and you can fine tune it from there."

Do not do this, if you want to keep the engine. It is a brand new engine. Keep sneaking up on it. Do not lean it out, then back it off.

I do agree that you should get it set initially with the governor off.

Get the top end so that it will rum consistantly, but on the rich side, then set the idle so that it is reliable. Click the main needle one or two clicks per tank until you have it breaking into a two cycle, then clean up the transition with the idle mixture (idle mixtur controls transition). Tweak the midrange needle after you get the other two set. Closing the mid range completely varies with engines-I would not take this as a set rule. Mine is not closed completely.

The three needle carbs are not hard to set.

Like your .50, it will run forever if it is broken in right.

If it were an ABC instead of a ringed motor it would be appropriate to run it leaner to begin with.

Again, profound apolgies to Emag.

[emag remrofni]

No need to apologize. Just different means of leaning the motor out. Your way is probably the right way, but 10 seconds of a lean condition will not harm the motor. I guess I'm just lazy :)

[Ah Clem]

Thanks Sean!

[emag remrofni]

Hey Richard, I'm rebuilding the Knight, do you know if the bottom of the main gear is supposed to sit on the lower bearing block?

Thanks

[HeliSmith]

Ah thank you Richard you explain things really great. Yeah I will go in a click at a time still no way am I going to toast my motor I have done a lot of reading tonight.

I do believe I am a bit rich. Maybe tail first stuff isn't a great idea when you are tuning your motor. :) It is messy.

[Lota Fun R]

I agree with Richard on this, you work up to it.

As far as low mid high are concerned, I'm really doubting you'll shut one completely off unless it's an engineering issue that hasn't been fixed, ie. new model.

Set your idle: the "pinch" test, pinch the fuel line off at idle, from my understanding, 4 to 5 seconds it should be ready to die.

The pinch test also relies on the idle rpm being set right, if it's ready to die, it's too low, if it's too high, there is friction on the clutch trying to spin the blades, half way between dieing and clutch friction is a good rule of thumb. 4 to 5 seconds with idle set properly.

Then set your main, if your main is closed an abnormal amount, richen your mid til the main is where you want it, meaning what the avg setting is.

That is how I do it.

My SX going south had nothing to do with tuning. It ran on the rich side with a carb smart before a combination of things took their toll, carbsmart wasn't working properly and I ignored it, wires were severed but still attached, servo was acting weird,that's one of the issues,my fault, it wasn't carb smarts fault but it could of possibly saved it if it was working properly.

YMMV:)

[Ah Clem]

Sean,

I will be able to look in a couple of hours.

There is a slight difference in the top and the bottom of the main gear also, If memory serves.

Did you order the white main gear? The black one I gave you was just to get you by in an emergency (or to use as a paperweight).

The white delrin ones never wear out.

[emag remrofni]

Richard,

I mean the very bottom of the tail drive gear, where the Jesus bolt goes in.

[HeliSmith]

Mitch nice points some I didn't find in my research last night thank you very much.

Sorry your motor died I have done worse on the ignore issue and not just once either. Sometimes you just wanna fly and you talk yourself into stuff, ah it'll be alright...

[Ah Clem]

Sean,

The autorotation hub, with the bolt throught the shaft, appears to rest on the lower bearing block. The tail drive pulley (black plastic on mine) is above that, flange side down, then the main drive gear is above that.

I cannot tell if there is a washer between the two, without disassembling my machine. I will dig up the exploded view later today and check.
