Used DA50. Runs great. Bought it from a club member and it ran awful. Sent it to DA to check out and they ended up rebuilding the entire engine, including new piston, rings all new gaskets ignition sensor and complete carb. rebuild (cost $128.00 and I have the invoice if needed). The engine runs like new now. The only defect is a broken top corner of the fin on the head (my fault, dropped it off my bench). Does not in any way effect the running of the engine Comes with a pitts smoke muffler, a canister muffler, Ignition, spinner, and stand-offs. Sold the airframe it was on so just selling engine now. Great price for this engine. Shipping is approx. $18.00. Any questions please ask. Trying to cut down on my hanger
