GP Piper Cub 20 size

       Remove this ad - become a site supporter!
I have a GP Piper Cub which is built for a .15 - .25 2 stroke engine.
Would like to request some help in choosing a proper size electric motor
configuration for it. (Power 25 Outrunner??)

Eflite set up to convert 2 stroke to electric!

Eflite guys have their electric outrunner engines with names like

Power 15 wich is suppose to be equal to 2 stroke .15
They make a Power 25 also!

you probably need a Eflite 40 speed controller and 3S 2100 lipo pack I bet!

The GP Cub would make a fine model to bring along to the SMALL event in Ottawa! this summer.

It'll depend on the weight of the plane, and how you want to fly it. I think the power 15 might be a little weak-kneed on 3s if your plane is over 3 lbs.

If you want to fly it scale/sport-ish, you probably want about 100 watts/lb (a little more if you want more sport, a little less if you want more scale). You need to find a motor/battery combo that will give you 350-400 watts (seeing that the AUW for that plane is 3.75-4.5 lbs).

There are any number that will do it, it just comes down to your budget, and how you want to fly.
Eagles may soar,
but weasels don't get sucked into jet engines.
