Hi all,
I just bought a used and completly stock revo off ebay. The previous owner has broke it in the way the manual says and has ran roughly 6 quarts through it. The fuel he used was sidewinder 16%. Here in the Uk i cant seem to get hold off the stuff. There are now two thing i need to ask;

will it do anything to the engine if i converted to a 20% fuel?

and what fuel would be the best out of the list below (the ones i can buy on www.modelsport.co.uk)

1.Dynamite Race Fomula
2.tornado fuel
3.model sport uk
4. Model technics

I appreciate any feedback,
zak
