Things I probably shouldn’t do

[sgtmike74]

Last night I was getting in a lot of practice on my BCP. Hovering, going forward, backwards, side to side. I was on my 6th flight, going into a hover when I heard a “POP” and my heli went down with quickness. Luckily it landed square on its skids and suffer no structural damage. The pop I heard was of the push rod popping off the swash plate. What had happen was my forward servo locked up and when I pitched back the two rear servo pulled against the frozen forward servo, popping off the push rod.
I was a little hesitant about working on the servo, but figure what the heck. I took it apart and found that one of the gears had broken a tooth and seized up. I rotated the gear 180 degrees and put it back together. Low and behold it works fine, I’m just a little concern that it might give out again but at the same time happy that I now know more about the inner workings of a servo and my heli as a whole.

That'll work as long as that servo doesn't turn too far. If it does, you CAN have that happen again. I guess it depends on which gear it was and if it makes a full revolution when the servo moves.

Sometimes tearing things apart is the only way of furthering your knowledge. Although, they do make gearsets for those servos if you run into that problem again.

I dont know the name of the gear other then it was a small one that only rotates 45 degrees to either side.

Trust me, it's not worth it, just replace the gears or even the servo, is it worth loosing your heli over?

[sgtmike74]

Yeah you are probably right, the safest thing to do is to replace it. I don’t know if they have the individual gears or if I will have to replace the whole servo. Either way a servo is only around $13.
