Probably, or maybe you can ask for the old version and get for $370. My high timer has the thin ears and 1st version mount but no probs if you don't crash it into the runway. Did this already ( 1st flight, radio module on transmitter went out ) Bob at DLUSA.NET provided parts (Cylinder, backplate, gaskets,and mounts) at what I thought was a reasonable price. It took about 30 minutes to strip and reasemble engine and it is my high timer now. My #2 has the thin ears and the second version mount and no probs at all. Probably 3 gallons on that one. #3 has the thick ears and stand offs. Very nice. 2 gallons on that one. It is nice to see that the manufacturer is listening to the customer and distributors and making changes to an already great design.
