Brison 3.2 engines 2 each with self starters
 

Never flown 3.2 engines with self starters. Don't know who did conversions. Started engines with worn out 3s 25c pack. Comes with JTEC mufflers and original ch ign. I personally would switch to RCEXEL units for advance feature. 400. each to your door. I have a video of engine starting if interested.
