Sinergy, Dick, the 26x10 in question on the DA 85 is a mejzlik 26x10. It is using a jtec pitts style muffler. I think a 26x10 or such is the best prop for any of the 80-85cc engines unless using a full pipe, but thats my .02
Yes for a 23 lb model and a loud Pitts in cowl - the 26x10 is a good choice for best power
but in that I personally dislike noisy setups - I use -when at all possible a silent can or a full pipe -and the power with the pipe setup right can be 30% better easily. still smooth, cool running, nice transition etc.. no loading up in any position.
I guess I will have to borrow a 28x10 Mejzlic just to "see" once more what the real load difference is with the 27x10
It is easy to get tricked if the reading is done on a 27x10/28x10 which is NOT the std ol model .
