brooke, If you go with a Hog Bipe (and you should), may I suggest building a balsa cowl for it. I think it cleans up the looks from the "stock" front end.

Here's mine with a 91 OS 4-stroke. I need to move the CG back a bit this season to make it more spirited. As it is it will do a constant knife-edge no problem, but I want to be able to get it to flat spin. The 91 four stroke isn't unlimited but it's a great match for the plane. It'll "just" hover at about 95% throttle. It's not meant to be a hovering plane, but that gives you an idea of the power.
