Although it’s possible to accurately calculate every important bit of data to determine the optimum power system for a electric model, most of us will prefer the "educated guess" approach. Unfortunately there is some knowledge required to make an "educated guess", and that is hopefully what this guide will provide.

For those completely new to the world of aero modeling and who also intend building a new model, I suggest starting from the beginning of this guide. Even if it doesn't all make sense at first, it will eventually. Some trial and error might not seem like the most economical way of learning but it can sometimes be the most effective.

Many people will only want to access certain information, so each topic has a heading. Look down the page to see if you can find the information you need.
