I test ran my Wren 44 in the airframe... and as expected, it fired up without any issues. (even from a dry system) It spun up... heard the propane "Pop"... and I watched the fuel go up the hose. And, as soon as it hit the engine.... the noise came up, and the HDT said... "Running". I've always been amazed on how quick this little engine goes from a start command, to running.
Once again an example of 'trends' making our hobby more expensive. Propane start is superior in so many ways,
especially how quick they start and how simple they are to fix if things go wrong with all the separate components exposed where you can get to them.
My 44 is an old manual start job, still going fine in a Bobcat 50. That's one plane I fly carefully reminding myself it's a turbine conversion of a $150 Chinese glow powered model!
