Hi Gang;

A little feedback on Norvel engines.... I was a helper pilot at AirVenture Oshkosh 2001 where we gave 1700 kids a chance to fly a Sig Sky Baby with a Norvel .061 engine. The Norvel .061 produced great power with reliability. Once we had the needle set it was easy starting which is good. Kids don't like to sand there with the handle in their hand while an engine is tinkered with. I was skeptical of the engines before that week but after 1700 flights I was sold.
My brother in-law has one on a 1/2 A Kaos and has a ball with it. The throttle works great also. Run with 35% nitro.
The engines do need to be broken though since they are shipped with a tight cylinder piston fit but once broken in watch out.
