Default .061 to .074 size to electric

Building a Mini Kaos and the plans call for a 061 to 074 engine. I'm going electric and need info for the correct size motor and ESC. Would a 370 and 18 amp be too much? I'm thinking it would be. I'm old school and have always used nitro. New to electrics. Battery most likely going to be a 3S 2200mA.

By choosing a smaller prop, a power system cannot be too much. You cannot overrev a motor with too small a prop.


Plane type and mass are leading when choosing a power system.

Not a specific answer for you, but in general ...

It is a good practice to have some headroom built in.

And pleasepleaseplease, do your RC equipment, wallet, ego, battery, controller, motor, house/garage/car a big favour ... get a watt-meter. It will more than pay for itself, will save you at least one fried motor and one fried controller. Will also help you finding optimal setup.

Without a watt-meter you are in the dark. Until something starts to glow Name:  frown.gif
