RE: Razzle 3d?
I flew my Razzle with a supertiger x-61 and it did okay. It took all it had with a 14-4 to hover it, would not pull out very well. When I recover the wing, I will put a 4-stroke 90 or something close to it to help with the power department.
Good luck with your 61, it just might do better than mine.
