OK.... I'm not going to argue with him, but I <have> to say that Kris has an exceptional motor compared to everyone elses account of the 102 - my 100 turns a 26x10 Mejzlik at 6500, a 26x10 NX at 5900, confirmed <normal> on RCFAQ.com, and with Keith Baker who claims only a 300-500rpm increase with the 102... 28 lbs with that engine is on the high side of where I would go with it, IMO, the 100/102 is best suited for the 23/25lb airplanes respectively.
In short, I think perfect for either application.
