help reg my Hummingbird V4 (am a newbie).

hi guys,


i am having troubles in hovering her.
This is all i did:
1) I made rudder adjustments - while she was ready to hover -but still wasnt there yet.

2) While i tried skidding (indoors - no wind) she kept skidding to the left. I tried trimming but was not enough. So i changed the length of the aileron pushrod. This stopped skidding to the left and i shud say she did seem good to go then.

3) took her outside - no wind. Tried hovering - but she kept moving towards the right. she was not banking as much as she was moving. she didnt crash either - i managed to get her down without crashing (thnx to my training kit). But after one unusually hard landing (still no broken parts Very Happy) .. she started moving her head to the right. And still the movement to the right is there - and both of these would NOT be cancelled by a trim adjustment on the Tx.

Can someone tell me what else to try?Rolling Eyes

I wanted to try adjusting the gain on the mix - but would wait until u guys say it is good to do for a newbie.

thanks a lot again.

reg,

your mistake was in trimming on the ground. when the heli is spooled up you are in ground effect---the rotor wash (wind) is bouncing off the ground and back up into your airframe and it plays all heck with the aerodynamics. when you changed your aileron length to keep from drifting to the left, you put it out of trim for when you take off. reread through your own post....you said it. it was drifting left...you fixed it...then when you took off it drifted right.

put it back where it was--drifting left (which is perfectly normal) on the ground and learn to fly through the ground effect. then, when you get up about 3-4 feet in altitude then you can trim for hover.

good luck.

hi cudaboy

thanks for the reply.

tried those things. now she is fine reg those problems but she broke her landing struts.
so grounded for the time being (my hobby shop is closed for a week i guess).
