New Beam SE and SPMAR7200BX problem

[Smudgyboy]

Just finished building my new Beam SE, installed a SPMAR7200BX and set it up. I have a couple of these on bigger other Helis, and work fine with the foam provided.

Problem is when I bring the Beam into a hover the disk seems to oscillate, the tail is rock solid and I'm thinking it could be the foam. Never used one on a small heli before.

Thoughts?

Thanks

I have a regular BeastX on my 500 and I had to strap it down a bit more snug as it was able to vibrate at certain headspeeds causing it to want to roll by itself.

My other thought would be maybe try turning the cyclic gain (pot 1 on the regular BX) down slightly and see what happens, I'm wondering if it's the equivalent of a wag from high gain.
