All right, with all these whizzy new gas engines coming to market and electric this and that, along with mega $$$ YS four strokes, just how much thrust is really required to achieve the "stupid power" that everyone seems to crave? Last year at the US Nats it was windy and nasty and the electric setups didn't do so well in that. Can anybody actually quantify how much is enough and perhaps offer opinions on how much pitch you need to keep the thrust going at higher speeds? Put another way, for the mythical perfect power system, what prop would it turn at what rpm (static)?

I'm just trying to find the best power system for my new Pentathlon kit and it is getting a bit cloudy out there.

BTW, the new ZDZ F3A 40cc gasser is quite attractive at $550 with ignition. Much better than I was expecting...Still not cheap, but the operating costs are peanuts after that first big hit.


Thanks,
Mark
