Yes it is possible to change to any other fuel. You just have to re-tune you engine.

Run it easy the first couple of tanks while adjusting the tune to compensate, and it will be fine. It would probably be fine if you just filled it up and floored it, but better to be safe than sorry.

You can switch to any nitro fuel up to 20% with only having to make a simple HSN adjustment....a little richer is what it will need. Now if you go up to 30% or higher, you have to also go to a colder glow plug and retune the carb HSN richer....I use Dynamite big block R5s in mine with 30% fuel.

edit-some people don't go colder on the plug when running 30%, but it's always best to run the proper plug seeing as how engines aren't really all that cheap and glow plugs are.

Right. Stepping up from 15% to 20% will only require a slightly richer tweak of the HSN. Your factory glow plug (R4) will be fine. Don't worry about temps either, tune for performance.

Going to 20% is no big deal but if you go over 20% then there are things you need to do. If it were I, I would put the 20% and see how it does. Then tune as needed and make sure it is not getting to hot. The only thing I have run so far is 20%.
