RE: flyzone diablo
I just took my Diablo out today for the first time. Had the same cg issues - too far back. Plane does seem to float on full throttle instead of fly. This also makes me wonder about the deflector. However, I'll have to fly more to decide. We noticed radio issues when testing. Moved the receiver back and it was better. The engine cut out momentarily several times when flying though. Now, cg I can mess with, but transmitter/receiver issues I don't like. I'll put in my call to Hobbico tomorrow too.
It is a nice looking plane. The upgrades are what sold me (I have them, but as a beginner I am reluctant to try them out yet). That dirt scoop on the bottom of the plane is something else!!
