Hey Chris

I can confirm what driesbabe is saying in regards to the rcexl ignition systems. They are all but bulletproof when used properly. Some of the caps that plug onto the spark plug can be tight and they need that extra push to connect.
The RCGF 45 engine is a joy to use. I have an old ACE BIG BINGO, and this engine hauls the plane across the sky. I know that you will have a blast with this engine. The plane you have it in is perfect!

Best to you.

Henry
