I love this model & wanted to keep it but its just too big & I know nothing about radio control models of any sort. This was a gift to me after doing some work for a guy so know nothing about it other the guy used to work for modelers world magazine so knew what he was talking about. Its just the aircraft , no radio or anything else ie just whats in the photos. The engine turns over using the prop & seems to have lots of compression but again thats all I know. Its made from a type of plastic, not fibreglass or wood.
