simple: wobble

[roc2it]

OK, before I get my day off tomorrow and start going through my "I just bought it used" Heli I wanted to gather some opinions. I have not exactly read anyone describing the exact problem I am having. When My Rap V2 sits still it is calm but if you bump the sticks the body wobbles under the head. I had a frind fly it and he flipped it upside down and held it there but it really wobbles with input. The dampners have been changed and there are those Maveric USA colored cf blades on it. Let me know what you guys think and I will do the run through tomorrow. Thanks, Rocco

Possibly low head speed.

hello have you found wobble issue if not let me know i might have an idea ive had a few with wobbles myself

Hi. I haven't had any wooble on my machines but on a R50 of a friend of mine we had bad wobble.
We put it on the ground and went over it for defects, we did not find any defect parts so i decided too take a chance and adjusted his headspeed up quite a bit and the wobble stopped.

So far I have replaced all the bearings and the head block. Went to the red dampners. Checked the carbons for cg and balance. Changed the clutch. Have not had any luck yet. Plus on top of all that I realized that the fuel clamp was letting the fuel push past when filling and flooding the head. What clamp is really small and clamps the line well? I am going to keep pluggin at it and see what I can come up with before the snow flies here.

how does fuel get to the head when filling??
which line are you fuelling from?

[roc2it]

I have a t installed between the tank and the motor. Yhe clamp that I have on there is not squeezing the line tight enough when my pump pushes the fuel in. I have another clamp but it is big. Would rather find another type of small clamp that works well.
