The Bobcat is a very good flying model, i feel it is built well also, the .46 engine is probably ok, but the carbs they give you for it are total junk, go with the .42 Thunder Tiger option, the servos are really cheap also, i replaced them with standard JRs and put a TT .46 in it, but there has been a lot of guys using the servos that came with them, the plane flys very nice and lands easy.
