. When methanol prices rose to over $5 a gallon here I started experimenting with E85.
edit....
My local prices for 100% methanol are ~$15 USA gallon and been static for several years
My Gasoline and E85 prices are ~$ 6.50 a USA gallon
Most Europe would be simalr high prices due to tax so E85 is a very very interesting option

The engines I have tried are older OS FP .25, OS FP .40, Vecco and K&B .61, newer OS LA .40, Super Tigre .45, Thunder Tiger .46 engines (several of each). They all have similar operation on E85, with the older engines running the best.
edit...
Ethanol would tend to run best at lower compression ratios (CR) than Methanol But higher compression ratios than Gasoline
Probably find the older engine are built for low CR with high nitro to bring CR back up

Realistically you can expect a drop of at least 1000 RPM, and likely several 1000 RPM.
edit...
On a engine with 10,000 RPM with methanol a drop to 9000 RPM would often mean ~20% plus drop in power and not 10% due to the drag^4 affects on props
With the cost of motors being very low relative to fuel cost simply purchasing a motor with 25% to 50 % plus bigger size in CC or cubic inch would often still make this a very interesting fuel to use when Methanol cost exceeds $ 5 a USA gallon and at $15 a no brainer
Thanks for saving me experimentation with straight gasoline from your results
Its E85 or E85 glow mix of some sorts
thanks for the links
