Thats what Iwas hoping to hear, it seemed like 10% nitro was a little high. Icurrently have an 11X8 on it for testing which Ihope turns out to be a good choice for flying.
It seems to have a nice throaty growl to it, Iam using an Aviastar 46 muffler which is a direct bolt on.
So far it is tuning up and running great, hope to get some tach readings soon on lower nitro fuel.
