Smell . . . now that's something I can latch onto. Plus sound, that I get but adding my minimal novice 2 cents as a Sportsman I would say my pros for electric are:
1) No idle adjustment.
2) No clean up.
3) Quiet.
4) Instant on; instant off.
5) No smell.
6) Ease of changing power systems.
7) No pulling glow plugs from a 7000 RPM motor.
8) No need for a starter.
9) Ease of installation. No pipes, plumbing, or reinforced firewalls.
10) No change in CG.
11) Zippy Rhino packs or TrueRC packs are now REALLY cheap.
12) Neu, Pletty, AXI, and Hacker have all broken the code and come up with numerous options.
And that's all I can think of at the moment.
2Sunny,
Only the first point to start and keep it simple.
Do you remember you did start the thread : Downline vs. Upline speed?
This was the first post you did receive.

You need to take into account your idle speed setting for the electric. Too fast and you are making additional thrust going downhill, slower speed will allow the prop to produce more drag than thrust and slow you down. You just need to experiment and see what idle setting will slow you down. Also braking action built into some esc's if used correctly makes a big difference in downhill speed.

Did you forget this already? (Did you forget to response?)

I do use airspeed control/cruise control and a data logger in my Taurus.
The trottle servo in the plane is controlled for that by the airspeedcontroller, so need no any adjustment. With my "trottle stick" I adjust setpoint speed.
For me it isn’t important how to generate speed or brake-power, electrical of glow, only how to keep the airspeed of the plane constant, on the value I want, because that is most important to fly pattern and model airplanes also in "bad weather conditions". Downline vs. Upline isn't a problem for me either, I only hear the engine does makes some more RPM Upline so it cost some more money (Dutch!).
Picture of the Taurus, white circle the ::Prandtl tube of the airspeed control.
Second picture detail of the Prandtl tube.
To have a powerfull linear output of the glowengine, also in any position of the plane and on any moment, I use two extra fuelpressure controllers one on the carb and one on the tank, so the output is the same as electric, only not limited in time.
