I had a small incident where I ran into a cabinet with the heli. Nothing was broke, just popped a link. The tail, which has a wow upgraded 120 motor, now doesnt hold right and it kicks out periodically, even when just hovering. I looked everything over and it looks fine. Any suggestions?

I flew it a little more and it seems almost like gyro sensor is messed up, either that, or I have a bent feathering spindle. Cant really bend the mainshaft because it is carbon fiber I think.

Check and make sure the tail motor wire isn't pulling out of the board. Very common in a crash. Chuck

for starters does the tail spin freely? Sometimes the tailblade can get forced on further and rubs on the motor housing.

Setup is everything, All my heli's can fly far better than I can pilot them

I've checked it all out, everything seems ok. I'm gonna take it apart tonight and check everything over for bends or cracks.

One of the this I did to my tail rotor plug pins is bend them ever so slightly together to maintain concection. Others on here tin the connectors.

Friends don't encourage friends to fly helis! It can cause part shortages.

Make sure your tail blade has not loosened on the motor. I had today where it would be fine, then seem to develop a wag. Took a look and the blade had loosened up on the motor shaft so it was slipping slightly.

Just a thought

I used all of your suggestions and could not find any sore thumbs. It has a slow wag, but I can deal with that.

Once suggestion for you

there are a few things I have seen as the key areas to stress for new pilots. Some get it right away and some have to work at it.
They are in no particular order because they all have to be learned to be successful.

1.WIND
2.Orientation
3.Speed
4.Altitude
5.Over Control
6.Preflight Check

I know this seems way obvious

I had what sounds like the same thing happen after a crash but after unplugging the battery and putting another in it went away. maybe cleared the system or something?

Did he crash? Dang, I missed it!

A solid carbon fiber tail boom solves this issue.

A SR 120 Tail boom is 3 mm in diameter so it would not fit. A 2mm solid rod is a good replacement but you have to put a flat spot on it where it enters the frame (easy to do with a dremel or file).

You can get 2mm solid carbon rod in lengths and cut to the length you want. I picked up some for about 4 dollars and made 6 booms out of it.
