RE: Mojo .40 engine?
If you are not 100% set on getting a saito you may also want to consider a YS 63. I have a saito 82 as well and honestly there isn't much to separate them. The saito will spin about an extra inch of prop but the YS will give you more rpm. Power wise they are about equal. The YS transitions a little better, they both vibrate about the same amount. The only other difference is the YS has a pressurized fuel system. Don't be scared off by it, it is easy to set up and offers more reliable performance. The YS is a little more sensitive to the needle settings however.
