I have been flying a BUSA Taube 90 for years...with just a Saito 80 for power. With that small motor, it took a bit of lead up front to get the CG correct, and as you may expect, it is a slow docile flyer. I can coax it through a very slow roll, but it does try to fall out of it...probably due to it being a bit underpowered and slow. It floats well, and I even played around with programing the Tx so I can droop both ailerons and have them act as flaps,....it'll do some nice, low & amazingly slow fly-bys that way, and if there is a bit of head wind, it'll nearly stand still. Not an exciting plane to fly, but it makes a good showing at special events.
