Had my maiden with my DL50 today. Ran like a top. Getting 7400-7500rpm with a Xoar 22x8. Dont have quite 2 gallons thru it. Using Penn air-cooled oil. I only got 2 flights due to elevator problem grounding me. Have it in a Aeroworks 50cc 260 and vertical was outta sight. Plane came out a little heavy (19lbs), but thats not unusal with my planes. This is my first gas engine and I dont ever want to go back to glow.
