Title: New 91 engine test
Post by: Paul Smith on January 28, 2017, 06:43:40 AM

I'm hoping to bark this NOS engine I bought.  I can't read the instructions but it seems to be 91 cubic inches.   I've got it lagged-down to a couple of 2x4's and hooked up to an old half gallon tank.

I put the muffler on to to keep the policia off my back. 

If the temperature stays above 40 on the English scale today might be the day.,

Paul,
Had you won your bid for office you may have had some influence in allowing test runs to happen.  Be sure you anchor that beast down as the .91ci engines are rumored to tug like a freight train.  Also, take special care when flipping as you might limit your counting abilities to 9 or 9.5 when not wearing open toe shoes.

Looks like an .061 to me

Thats an AP .061

They used to be carried by Hobbypartz out in CA.

They like to turn up.

I hope it goes.  I have a project in mind.  But I won't start work until I bark the engine.

I also need to bark a Fora .049 for another project.

Well since nobody else apparently got that this was a tongue-in-cheek joke I guess I should acknowledge the clever set-up. BTW I have essentially the same engine, a Norvel .061, that I use only in free flight and which does indeed turn some impressive revs. Not like the Cyclon .049 that does 36,000 but pretty respectable. Yes, keep that beast under control!
