Thanks. I read that thread a while back before becoming a member of RCU. I even came up with my own gas/glow brew for regular two stroke glow engines. It is 1/2 gasoline with 25% oil and 1/2 0% nitro glow fuel with 25% oil (I made the glow fuel part myself). It worked great in a Fox .40 R/C with an OS A3 plug. Never had a dead stick.

If 7500 is the max for the Ryobi then, my 7000 isn't as low as I thought.

I'll try some nitro tomorrow and report back.

Do you think a Ryobi could fly (not 3D) something like this:

I mean I have made dozens of regular size glow PBF's and I would love try a giant scale version.
