Thanks for the replies. I think I will stick with the 1.20 like I originally planned even though it seems big. I had a smaller bipe several years ago the flew with the .80 and thinking back on that it did not seem overpowered at all so I believe the .80 is out of the question. That Super Stearman did require quite a bit of extra weight up front also so possibly the bigger engine will be a plus. Thatnks again for the info and opinions.
