Need to Determine the Cause of Instability ONLY when going forward or backward

Hi. I bought a Syma107 for my kids.

During their first flight they crashed it into a wall and broke the small black pegs on the main shaft. I purchased a spare and replaced it. Now the heli is stable when you take off and land and also when you turn, but it becomes unstable (toilet bowl motion) when you try to go forward or backward. Can anyone tell me what they think the problem is now?

 

Thank you in advance!

Hi swnyc2 and welcome to the forum.

 

Could the main rotor shaft be bent ?

It doesn't appear to be. How do you recommend I evaluate for a bent rotor shaft?

If it's not the main rotor shaft, could you suggest another place to look?

OK guys, so what is loose that causes the heli to TB when going forward or backwards, but it will hover in one place and rotate left and right just fine ?

This should be real easy to figure out. Surely someone out there has had that problem and fixed it before.

In chat, you asked if if the shaft could come out the top. I said no, but im not really sure about that. Maybe someone here can straighten that question/answer out for us.

I think i've only seen people pull the shafts out from the bottom.  Is that correct ?  Dennis
