My limited experience with electric model airplanes has taught me: Vibration is very low, you can build much lighter structure. Lighter structure is limited by full power torque which will rip a=20 firewall out. Motors don't quit when they hit something, they keep on chewing. An electrical fire won't quit until you remove the power. Always=20 know which pocket has your wire cutters! Don't transport batteries without a plan to immediately jettison them.
