There seems to be a new trend in leting the engines to run faster so that more thrust is produced due to the engine being in its power peak. Sur the engine will be louder but tuned cans and muffled can get more and more popular hence the fact that smaller props for a given engine become more popular.

I plan to fly a ZDZ80RV on 80x300 can from RCS with a Mejzlik 26x10. It seems that I should get between 6500 and 7000 with this prop and muffler combo.

Question: what are the effects to the engine as far as temps, longevity, fuel consuption, etc. ?

Lots of guys around here load their engines to death and I want to be able to prove them wrong, or if it is me that's wrong, at least I will change my prop.

Thanks all.
