Tommy,
As to speed you will find that the 9x8 will give you much more potential than the 10x7 even at the same rpm
If we ever get any warm weather in the next month or so, I might for giggles try the smaller diameter prop. I do think while no doubt it will be spinning faster then the 10"er it will not have the ability to fly the model faster, in top speed. Do hope you prove me wrong however.

A tuned exhaust is nice for its extra power; but one needs to set it up exactly right and it is very easy to get it wrong...[

Would you care to educate me on the correct way to set one up? If this is a far too common question, by all means a link would be more then adequate as well.
Thanks!
