Aww now that's no way to encourage somebody to step up the level of modeling experience required to do more than plug in a battery and push the left stick up to the stop! [:'(]
The best thing to do is come up with the starting method that works best for you. Some of my engines readily start with a simple backflip of the prop on the compression stroke, while others just need the zing of a starter to get them going easier.
Good for you for enhancing your modeling experience with something that burns more than electrons!
