Hey guys, I'm really stumped on this one. I'm in the process of modifying my CP w/ an ar6100, and an e-flite 3in1. I'm obviously missing SOMETHING, but it seems no matter what I do I can't seem to get the swash to move in the proper direction when left stick is applied. It slides up with "up" stick, and down with "down" stick. It SHOULD be the other way around. Right? Swash menu is at 3 sevrvo 120deg. Swash mix is aile=+100, elev=+100, and pitch is -42. I know the obvious thing to do is reverse the servos but all that does is throw off the cyclic. And there's my dilema! I can't seem to get them both working (cyclic and collective) as they should. Cyclic works perfect by the way, I wouldn't want to touch it. I've reversed the swash mix as well, pos to neg, neg to pos., with the same result...it throws off the cyclic. Any ideas?? I'm still fairly new to this, so I'm hoping it's something really simple that I'm overlooking. Any help will be greatly appreciated! Thanks.

turn down the swash mix to 80.. ccpm2 should be -, ccpm 3 should be +, ccpm 6 should be -

if you reverse the servo then just change the ccpm setting for that channel to + or -. if its + then change to -... that should help if not fix it..

Thanks for the reply tx. However, I dont quite follow you when you say CCPM 2, 3, and 6? Can you elaborate on that? All I can say is any change I make on the collective like you stated, it throws of the cyclic. Correcting the cyclic, messes with the collective. It's like I'm going back and forth with no progress :arggg: I'll keep scrathing my head, and see what happens. Thanks again I35 neighbor.

no problem here is what i ment

you have the ccpm settings for 3 channels aileron, elevator, and pitch.. they should be channels 2,3, and 6 ( 6 being the aux channel on my ar6000).

recently i screwed my stuff up, just got my first test flights in today, but i gotta work some bugs out.

i found that ccpm 6 ( pitch ) if i go from -35 to +35, the collective stick wroks backwards. from center stick if i want to lift off id ahve to pull it down, instead of moving it upwards. so if lets say you fix the collective but the cyclic is screwed up. test if its aileron, or elevator. move the cyclic stick up to full throw and then down to full throw.. does the swash tilt forwrd with the stick up ? lets say it does.. ok so you know that the elevator is working correctly. then test the left to right movement of the cyclic stick to the swash. if you do that and when move it left the swash tilts right. then try reversing the ccpm setting for the aileron channel. if you have it set to lets say + 80 and its not working correctly then set it to -80. the servo reversing i have is this

pitch normal
throttle normal
aileron rev
elevator normal
rudder rev
gear normal

Thanks a bunch tx! If it wasn't so tired I would get crackin' on it right now. Not to mention the dx7 beep would drive my wife insane if I started pushin' buttons while she's trying to sleep! I'll get a fresh start on it in the morning(hopefully) and see how things go. Thanks again.

good deal post up if it fixed the problem or not..

GOT IT!! To be completely honest.....I'm really not sure if I'm doing it right. Everything is moving the way it's supposed to so I'm not TOO concerned. The reason I say that is because the "fix" was setting all the CCPM's to positive :dontknow. Whatever. Live and learn, right? At least now I can move on to the other stuff. While I'm at it...You know the ESC light? It turns red at about 1/4 stick up. Is that OK?? The only way I can rememdy that is to crank the throttle ATV all the way down to 35. That just doesn't seem right. Any ideas on that one? Much thanks!

hmmm
whats your throttle curves at ? what about the throtle trim..

aslong as it everything works as it should i dont see why you couldnt fly it like that till you learn more about setup and programming

All trims are zero. Throttle curve is 0, inh, 86, inh, 100. W/ expo on. Like you said, as long as it works I'll just fly and see what happens.

i only run like 3% expo, so dont put like use alot of it. i wouldnt also fly with your throttle trims all way turned down..i hope someone else can chim in cuz im kinda stumped

Doesn't matter which way the swash values are as long as the swash is doing what it's supposed to do when you twiddle the sticks.

One thing a lot of people still get confused is the servo name vs. CCPM function name. The pitch servo is not the same as the pitch function, aileron servo is not the same as aileron function etc...

Getting the swash moving the right way is easy..

Connect everything up then power up the electronics with the servo horns off. Center the trims and sticks then stick the servo arms on and connect the links to the swash. Don't worry about subtrims or getting everything perfect right now.

Move the left stick (Assuming Mode2 here) up. Do all the servos move the same direction? If not, reverse the direction of the oddball servo to get em all moving in the same direction.

On the CP, the swash needs to move down to increase pitch so moving the left stick up should pull the swash down. If the swash is moving up with the left stick going up, change the pitch value in the swash menu to the negative of the current value. (If it's +50%, change it to -50%)

Now you've got the swash moving the right way for collective. Center the left stick and then move the right stick forward. Does the swash tilt forward? No? Change the elevator value in the swash menu to the opposite of the current value.

Now move the right stick either right or left. Does the swash tilt (when viewed from the rear) in the same direction as the stick? If not - you guessed it - change the value for aileron in the swash menu. You're done. Now you can dial in the head.

To recap: Use servo reversing to get all the servos moving the same direction with collective then use the swash functions to correct the direction of the swash movement. The radio doesn't care if there's a negative value in a swash function or if a servo is reversed, it's going to provide proper direction and mixing to match your heli's setup.

thanks man i was alittle worried my self that i was doing it the wrong way, and i dont like to spread bad info around.. aslong as everything did what it is supposed to do, was good enough for me

Skidds....That needs to be a sticky. Thanks for taking the time to do it. While reading it I had one of those light bulb moments! It finally, truly made sense to me. I was one of those who confused the whole servo vs. function thing. Not anymore. Thanks. BTW How's the pool coming along?
