Gas engines can be used for pattern, but they are not going to be competitive, that's the problem, there is no way gas can compete against top glow or top electric engines/motors in AMA Masters or FAI.
To be competitive cost money, at least for know.
Absolute statements like this one just make me more determined than ever to complete my latest design and get it flying for next season. Planning on the ZDZ40RE F3A w/ tuned exhaust. I guess I have to show you the way. The trick isn't so much the design and gas power....
For me, it's the trying to design in enough lightness and simplicity so that average builders can do the same thing. I have threads on both the soft mount and the wing techniques I used. I may start one on the prop mods I am making. Wood composite props are not only much lighter than the plastic stuff, they are far stiffer.
