RE: Area 51 engines
I purchased an Area 51 from Extreme Flight a few weeks ago. This engine was mounted on an EF extra 300. The engine turned 7000-7200 rpms out of the box on a Vess 23A stock muffler. It pulled hovers at half and less throttle. It pulled out not much over half throttle. This is a new motor on lawnboy. On flight four however my chrystal came out of my JR receiver and the plane had a bad crash. The motor was damaged, cracked head, bent standoffs, torn muffler, and the ignition worked but had something loose. Anyway Milton replaced the engine as the warranty says ($215 shipping included) for another NEW not rebuilt. I own a DA with a solid header and carbon fiber pipe Vess 23A 7600 rpm mounted on an EF Yak and just sold a DL with stock muffler on a Dietrich extra 260 6800 rpms. I must say my experience with Milton has been great and with Chris Henson at Extreme Flight selling these engines, how can a RC pilot loose, $400 for a 50cc that pulls and turns like it is on a pipe.
