Dear Sirs;
I have flown a Chinese made trainer Venus 20 for the past year, now I can take off and land without mishaps and do some basic aerobatics(loops.rolls, snaps rolls.hammer heads. etc). I want to improve my skills, I am wondering whether the world model's Rambler-30 a good choose or not, Can I do knife edge with it? How powerful the engine needs to be ? Thanks.
