Hey all

Well last night I got to test out my new GV-1 on my Rap 50 SE. The only chnage to settings in the machine was to go to a full mechanical 3D set up and remove the engine to mount the two sensor magnets.

The problem I have is that when the heli was flicked into idle up 1 and the governor kicked in the whole heli would shake when a little negative was applied. The heli would sit in a hover perfectly fine but once on the ground that was when the shake appeared. The govenor manual helpfully says that if the heli shakes shut the governor off but doesn't actually tell you why!

I have cheaked the machine over and tightened everything up but can anyone suggest where else to look? The ground was a little uneven so that could be a cause.

Thanks

If you are in idle up on the ground with neg pitch, yeah it will shake. It's trying to push on the ground!

Where's that EASY button?

Yep, but I had a 90 pilot flying it and he said he had never come across it with his 90. I guess it is a little more stable.

Not sure about the 90. My rappy 30 does that. Now I don't do that anymore.

My helis will do it on hard ground but not soft, nothing to worry about just don't do it to long or you may get into ground resonance.
