Can a crash cause the sticky collective issue?

[baratta930]

Hi y'all,

I got a BCP a while ago but gave up on it because of getting frustrated trying to learn to fly it. At xmas I bought my son a lama v3 and that got me thinking about flying the BCP again.

So rebalance/level everything + RADD + 1 week of playing in the basement (6x10' space) and I'm hovering! Happy Happy Joy Joy ...

I changed the blades with some new JCS plasti-blades and was practicing hovering last night when I hit the TV stand and it came down.

Nothing seems to have broken but now even on a fresh battery the heli won't lift off with the plasti-blades. I switched back to the woodies and it's now behaving as if there is the sticky collective problem (never had that happen before).

Could the crash have caused the sticky collective problem to happen?

Could I have broken something else in the crash that is the real problem? Everything seems fine (pitch, swashplate, etc ...).

Any thoughts?

Thanks,

Berardino

You could have very easily broken the gears inside the cyclic servos, power off and try to manually move them through their range of motion with your fingers. If the action is not smooth then you have a problem.

Check to make sure your flybar paddles are level also, if one is off a little bit you will have a difficult time lifting off. The plastic blades are killers, I would personally go back to wooden blades until you have some more time hovering under your belt. Plastic blades tend to bend and not break, they break the things they hit, like the boom, or an LCD TV. The wooden blades break easily and destroy themselves, but don't kill the heli or whatever you hit with it.

It's also possible that you have bent the spindle that goes between the blade grips.I've have bent several of them on blade strikes,this will give you some strange collective problems, Paul

For sure check the feather shaft, and also check the shear pin didnt break. Hold the gear in on hand and see if you can spin the blades while holding the gear still.

I fixed the issue, the pitch in one of the blades got messed up and when I reset tracking on the blades I set it to the high pitch blade and ended up with too much pitch overall in the blades. I took out pitch from both blades and it's fine now ... still twitchy as s*** but that's a blade CP :)

My son's lama is starting to look like more fun every day :)

thnx
