We seem to have a Nitro habit in the USA, In Europe nitro is exspensive hence they use a lot of FAI and 5% nitro the Irvines and MVVS engines do fine on it by running a hotter plug
most engines will do fine on 5%

Also just engines in the UK just released a CID ignition conversion system runs about $80 not too bad , their test bed was a 80 size 4 strk thus running a gas/oil mix
I would guess with the new 2.4Gz radio systems ignition noise not an issue

There are now 2 other options diesel and gas conversions martin
