Well...

Since you seems to hate electrics why do you want to start a debate in the "Electric Flight" Forum?

A lot of us who fly electric have flown glow for decades. Myself I had my first takeoff with a glowmodel in 1975...
But today I have only 5-6 glowengines left, and they are for sale all of them. Why? Because glow is best? Propably not for me...
On the other hand I have at least 20 brushless motors, from small 40Watts to 3500 Watt setups. Is this because glow is better? Propably not for me...
Instead of glow I use gas-engines in my large planes. Both IMAC and TUGs. Is it because glow is better? Propably not...
I have some motorgliders between 1,5meter and 3,5 meter WS. Would I ever dream of putting a glow-motor on a beautiful sailplane? Guaranteed not!

In an other thread in this forum you adviced to put a glow engine in a "parkflyer"! A plane which is made for electric only and would vibrate to dust as soon as you started a glow clamped to it? Why did you say so??? Maybe a newbie would have believed in that?

If glow is your choice stay in the proper forum and discuss glow and planes which are meant for glow please. A lot of people still fly glow and will do so for many years still.

Do you want scale sound? Run an inrunner on planetary gear and you get a sound close to a RollsRoyce Merlin. Which glow would sound like anything else than a moped?

Like to build a twin-engine model? Electric is perfect. Instead of tweaking with two glowmotors never getting them running syncroniced two brushless motors just works.

Discussing airfoils: Yes please. More interesting than this. In fact one of the most interesting discussions there is!
