Well I can perfectly see why you are wanting to go gas after the JJ.

but get you a OS or Moki 160/180 and be grey hairs ahead of the game!! I think a Saito 180 would be a good match. Prop wise. Just don't want to deal with the P-factor on a model like this.
Actually I had great luck with the JJ - I guess I was one of the lucky ones.
Got the gasser to run on the falcon till I can get another turbine, and then slap the fuji on a small YAK or something. Also wanted to go gasser as I wanted smoke on the falcon, and you can't get real good smoke on a GLOW engine.
The plane is designed for a prop engine, so I would hope they designed it with p-factor in mind. I guess I can do a little more research on the others that have pusher props on this model to see if p-factor is a big issue.
I guess only time will tell. If it doesn't fly right, I will have to put a turbine on it sooner than I planned.
Looks like some bottom re-inforcement and a good "L" bracket will at least let me get here in the air and see how it goes.
