Might have an issue with the nipple/line clearance:
Using a 6oz. tank, still have to thrash the ignition and battery in.:
The supplied muffler bolts are a tad too long, but should'nt pose a problem. When I have all the required holes drilled for the pickup/plug wire/switches, I'll tighten it all down and locktite everything that needs it.
This one should be a hoot! The plane was powered by a rimfire 46 on 5S before the conversion.
