I just had CH IGNITIONS convert my FA 325R5D to pumped gas igntion system.
Planning to run it on a TOPFLITE P-47 85" c/w ROBART air retracts front and rear.
TopFlyte manual recommends 41 - 70 CC for gas engine. If I have worked out the conversion, my engine is 53cc., therefore in the mid range of the recommended engine size.
The engine weight prior to conversion was 5.4 lbs. Don't have it back yet to weigh but I am estimating the converted weight will be no more than 6.0 lbs.c/w the KELEO exhaust.
Your comments are welcome as is your advice and experience.

Going to finish in "Bubbletop", but have not selected the paint scheme yet. Any cool suggestions?
Thanx All
