RE: cost per flight hour vs. glow
YS 170 engine with a hatori pipe and header and the proper Hyde mount. Around $1000. Fuel about $3 a flight. Airframe wrecking vibration and oily discharcge that seeps into everything. Constant problems and expense of parts breaking and trips back and forth to Verano. UPS will kill you alone. Where's the debate? For my $ E. has been a lot cheaper.
We are running $100 Dualsky outrunners or the AXI generics Atlas for less that $150. The power I'm getting is as good as any glow system I have seen. It does not suffer in the wind or heat either.
The Atlas comes with a 3 year no ?'s warranty. TP and Hobby Lobby has the best customer service, much better than the glow company's I have dealt with. Mike
