Anyone new to electric models always asks, what do I need? Download the file below to see a table of Brodak Electric Power Systems ranging in application from .02 to 65 sized models.
The easiest and most direct way to determine what system you need is to start with the size prop you would expect to use if you were powering the model iwth an IC engine. Don't think 35 size or 40 sized, think 10" prop, 12" prop, etc. Start with the colomn on the left and read down to your prop diameter then acroos for a set of compenents that will get the job done. By all means cross check to the "List Your Set-ups" post in the All Amped Up forum and you will very likely see a match - or close to it.
