This is really the basis of my suggestion for a lighter propeller load. The 35-DS isn't exactly the best engine that PAW ever made. This was discussed on the Barton site quite a few years ago. A few examples went back to be "re-manufactured".

I used to run mine with a 12x6 or 11x7 - it was a bugger for vibration, but not prone to overheating/going hard.

Didn't PAW once try one with an18x6, just to see how long it would take to fail? ISTR it ran for many hours without harm, until they got bored with it and had to go home.

Still, I'm more fond of their smaller ones.

Mine used to run hot and tend to go over on a 12 x 6 prop when flying my Custom Cruiser. It was not exactly smooth either with that prop, or the 11 x 8 I used to use before the 12 x 6.

Thanks for sharing your experiences Ray. Will try a lower pitch prop. My .35 TBR will fly again as I am refurbishing my Cruiser.

you are right with 12 x 5 the engine run hot that was my fault. I run the fuel too lean needle quarter turn to half from close ! how you smell it? I thing I cut the end of the video !
