RE: A little issue with which engine, Webra speed 50
I use FIA fuel in my Webra's If you use too high of a nitro content they don't run so well and like to over heat. High compression engines, I have a Webra speed .61 on a Nitro planes Bobcat that spins upward to 14000 rpm on FIA fuel and I could get more if I leaned it but I like em a little rich, I don't need ALL the speed LOL Great engines though.
