Jim, I think a lot of people overpowered their Falcons and Sr. Falcons! As you found out, modest power flew the Sr. Falcon quite well! Carl designed those airplanes to fly on the wing and they did quite nicely! That's why they are classics along with Hal deBolt's designs.
I've got a Midwest deBolt T-Craft sitting in the box out in the shop that would fly pattern manuevers with a K&B .40 and still fly pretty good on an Enya .19.
Artisan, I would love to own a ST PDP Bluehead again. My Southern R/C Tigertail would be a perfect home for it.
