Converting USA engines to R/C

Forgive me for asking a question I’m sure has been asked before but can someone please direct me to where I can find straight forward directions for converting a USA engine to run on battery power. I am using the Aristocraft TE in a trail car. Any info is much appreciated.

Here is how I go about it.
BTW the “create link” icon did not work, so I added the end codes manually.

The attached link shows an F3-A & B conversion I did, with some significant additional hints from others.

Hope this helps.
