As promised I tried out a different fuel in my Vmax-6 LMH 110+ today. I found the results very interesting. The engine is well broken in and is using 3 shims. Todays weather was about 55 degrees, and very humid with on and off drizzles. I had been using 15% Powermaster, which has worked well. Its a 18% castor/synthetic mix. I bought a quart about a month ago, its always kept sealed and the hobby shop has good turn over. The fuel has worked well. I am almost out and tried some 10% omega airplane fuel, which is a 17% oil castor/synthetic mix. I have heard from some that the Vmax will not run well on anything but 15% or above. I think it actually runs *better* on the 10% than the 15%. The throttle response was a little smoother and there seemed to be more power at certain settings. I did give off a good bit more smoke than the Powermaster, which gives very little. So it IS possible to run on lower nitro percentages, and run well!
