RE: Electric, glow, gasser. Just choose one
I chose one over 40 years ago and have never seen any reason to use anything else. Light weight, sounds great, gobs of power, I know the ins and outs and the fuel costs are not unreasonable considering the size of planes I fly and the amount of fuel I burn.
I see others at the field using "alternate" power sources fiddling with what size of this, how many of that, what prop gives you the other or what widget do I need. I see people with alternate liquid fueled engines cranking their arm off to start an engine. I fuel up, fire up and fly up. First time, every time. My planes are fast, light, powerful, have unlimited vertical performance and do everything a pilot could want. As an engineer I always say if it ain't broke, don't fix it!!!
I'll let you guess which power source I run but I'll repeat the hint, I started flying it over 40 years ago!
