Electric over Glow

 25 October 2021

The model

Unlike glow fuel, electric does not have oil, does not need fuel proofer, does not need cleaning, any paint is ok.

The battery can be positioned to change the CG.

Motor direction can be changed easily.

The flying

The motor starts on demand and power is proportionally delivered, very convenient, doesn't cut off unexpectedly, is quieter and safer.

Electric may not have the same power as the voltage drops but we have throttle for that.

The CG doesn't change with electric models unlike glow fuel.

Less vibration, easier to have the prop spins true.

Other quirks

Power density is lower than glow fuel but the 'full-bore' appears higher.

Once out of the factory, the battery dies very quickly. Glow is similar, it attracts moisture, nitro evaporates, but has much longer usable lifespan than battery.

One battery is only one flight and that battery has to be recharged which takes about an hour whereas glow fuel is filled within minutes.

Battery is more expensive than glow fuel, although engine is more expensive than motor.
