RE: A not so SUPER TIGRE
Mine is the China version. There was another 4* 60 at the field. It had a os 61 FX. Just from watching it fly it appeared to have more power than my 75.
I have a tach, it is leaned out to the max, then I back off a few hundred rpm. I am running a 12/8. I have also tried a 12/7.
