In my post I did not recomend anything...just said it what could be done on around . 60 size ABC engines. I did not recomend Gas/glow in the first place. Just use a good RCexcell ignition and you can run about any fuel you want with correct oil in the mix. Like one guy said...you can run no Nitro at all... but the engine will run like the fuel has nitro in it. Capt,n PS you do not need a specail glow plug either.
