Hello!
I bought an Esky Lama V3 and have been flying it for a couple of weeks and it seems to be very stable and responsive. My problem is that when it hovers it makes 3' circles without any input from the remote. I tried adjusting the trimming but it didn't help.
I am hovering at an altitude of 8 feet to prevent any turbulence caused by the rotors in a closed garage with no wind either.
Any help would be greatly appreciated as I would like to fixt this so it will hover like it should!!
Thx!

I'm not too sure on this heli. I am thinking if it's anything like a CX2 you probably control the swash plate with two servos. I think what you should do it the following. If it's flying in circles it sounds like it's going a little forward, and a little right or left rudder. I'd say first you need to correct the forward problem. With your main rotors stopped, try moving your cyclic control stick up - as if to move the heli forward, and observe which servo moves in which direction. For instance - lets say you move your control stick up and you see one servo arm move up. This would indicate that the servo arm moving up is supposed to move the heli forward. Now assuming that's the case - and assuming that there's an adjustable ball link attached to that servo, you would want to shorten that link by screwing the ball end down on the rod further, so it's not pushing your swash in that direction as far. to trim this out mechanically you would center the trim on your radio, and then shorten the mentioned link until you got no forward or backward movement. If you tail is spinning around and you can't trim that out with the rudder channel trim - I think that there's got to be some kind of screw on your motor control unit. It may say prop (proportional), and you probably have another one that says gain. I would try to turn your proportional screw one direction a little bit, and then test fly to see what the results were...if the rotation gets worse - try moving it in the other direction, or visa versa if it gets better but it's still got some rotation. If you end up going through this process and it all works out well - and you still have the heli drifting a little right or left - you can try the same method to adjust the other servo associated with this movement.

I've never worked on a lama - but I would think that it's very close to a CX2. This solution will probably work out just fine. I hope it helps.l..GOOD LUCK!

Thanks for the quick response! Yes, it is similar to the CX2 (4 channels -FP). I tried already adjusting the proportional but that fixes rotation. In my case, there is no rotation. The Heli is always pointing north and it moves N-NE-E-SE-S-SW-W-NW-N.....but always pointin its nose to the north...
Any more ideas? thanks for your help!

that might be TBE or toilet bowl effect, and basically the reason that happens is that the lower rotor set is generating more lift than the upper set. This can happen for alot of reasons. You might have a deformed blade and just need to replace them, or you might need to lube your shaft or something.

hopefully that helps you diagnose the problem, and it not just let us know

Thanks for those ideas! I will try replacing the blades and will post the results.

This is the same problem I have with my V3! I see it is a while since you wrote this how did you make out with the corrections? My Esky was flying fine for a couple of months, landing on stools and tables was a blast. To many pilot errors forced me to do repairs. I figured as long as I was adding parts I upgraded to aluminum. The swash plate was the first to go. New extreme blades, then blade holders. At some point in the repairs the circles started. Not a lot of fun to fly anymore.

Hi,
I came across this one a while back myself and asked the same question.
A helpful RCU member suggested I check the flybar as it may be bent.
It looked ok but I took it off anyway and rolled it on a flat surface and it was indeed bent.
I managed to straighten mine and the problem was solved.
I was flying a lama XRB contrarotating heli, it may be very simular to yours.
Hope this helps.
