I have the .60 Extra sold by AK.Not sure who built it.Its a decent plane for the money(hardware is junk).I put a Magnum .91 2 stroke with a pitts muffler.Its pretty stable in the air and tracks ok too.To get crisp aerobatics,I had to crank the throws way up,but then it turns like a pylon racer.I have a skysport radio w/out dual rates.I think that plane w/ the 1.00 and a dual rate radio would make a decent package at a decent price.BTW,the landing gear are for perfect landings only.
