Is it me or does the blade constantly need input for a stable hover. Once I get settled into a hover it still is withen a three foot circle. I cannot get it to hover "still" but for only a second. I would suppose its size has a lot to do with this. as with my experance with airplanes the med. to big sizes make for a better trainer. although there are a lot of small electrics out there their flight peformance does not compare with a .40 to .60 size. is this true with helis also?
