P.S. from my last post ( I always forget something). There were some questions about power loss with E85. Some posts claim there is only a few hundred RPM drop in power when compaired to commercial glow fuel or methanol without nitro. This is not my experience. Realistically you can expect a drop of at least 1000 RPM, and likely several 1000 RPM. This is a substantial power drop. To get a good idea of how much power you lose, download the free "extended prop" software and calculate the power loss from:

The software available at this website is among the most usefull I have encountered. Some programs are not free, but the prices are one step above free and top notch.

Good luck!
