well you can swith brand's alone it is 20%.. but i would stick to the brand you broke it in with ... just my 2 cent's

Genius

you can use any type of fuel with any percentage of fuel. sometimes people use 5% to break in and then 30% to race. You just have to retune the engine when you switch cause different fuels even if they have the same percentage they have different characteristics or burn a little different. Its probably best though if you just stick to one

i have changed brands and percentage many times never with any problems....

switched from different fuels (blue thunder, cosmo, odonnell) but all @ 20% nitro, didn't have any problems... my engines seems to be running well even at 4 gallons

just stick to same nitro %, brand would then be your preference...
