Hey captinjhon! you may try to look for an E85 source by typing www.e85fuel.com then go to the refueling stations bar on you left it should give a list of all the retailers on your state, let me know your results, by the way I went flying this last weekend on my fairly new conversion of an echo 25 weed wacker engine without the ignition and converted to glo the engine weighted at 1lb 12oz and can probably bring the weight down some more, I flew it on a Hobby people's Exite 90 ARF
with the 60/35/5 gas/E85/nitro and got 8000 rpm's and was flying that plane on a 16 oz fuel tank for periods of 25-30 min on a single tank, so that are good numbers that I can be content with. Ill keep trying different combinations of fuel and maybe some modifications on the engine itself to bring those rpm's even higher, Oh! and I was forgetting one important
thing the LOW IDLE was perfect whit good trnasition from low to high speed.
