RE: BSE .61 LX DUBB JETT
huey-pilot said this in another thread. It seems like I read a few things about this engine in this forum so you may try a search.
"I have a Jett FIRE 60LX on a Diamond Dust, the engine weighs the same and is the same size as the Jett .50, it turns a 8.8x9 APC propeller at 19,600 rpm and a 8.8x8.5 APC more than 20,000 rpm on a pipe that was purchased with the engine."
