Yellow Aircraft ARF's are a little more expensive than the competition but you get what you pay for! I have the 30 size Extra 300 with a Magnum 52 four stroke for power. Quality was very good, Monokote covering was wrinkle free and the parts fit was excellent. My only complaints were with the wheel pants which don't match the covering material and the manual which had an error in wing mounting dimensions. Flight performance is good and landing manners are very docile (no tendency to tip stall), excellent for someone wanting to transition to a low wing aerobatic type aircraft. More advanced flyers mignt find this plane a little on the tame side due to a fair amount of dihedral and a semi-symetrical wing.
