Thank you very much.

Your Aviastar .46 should run fine on Omega 15% nitro fuel. I'd recommend trying a Fox RC Long glow plug w/ idle bar or an O.S. No. 8 plug. The 15% nitro content is a little high, so a medium/hot plug will likely run more reliably. A hot plug like an O.S. No. 6 (A3) may cause pre-ignition issues with higher nitro fuel.

Good luck!
