Default RE: GSP Sukhoi very tail heavy. HELP!!!

Waall I'm sitting here figuring the 69.5" wing has maybe 900 squares in it, and Brent thinks his plane will weigh no more than 12 lbs, which would produce a wing loading of something like 31 oz/sq ft. That's the same loading I flew my Creek Sukhoi at, which wasn't bad at all. I enjoyed that plane for two seasons, did a lot of good flying with a YS 1.20, APC 17x6. Just not quite enough power for all I wanted it to do, so I retired it to use the engine on another project. So yes, probably a bit hot on the landing, but could be a very workable combination with the FPE 2.4. I guess my only suggestion now would be to balance the prop well and tune the engine for least vibration, since there's not a lot of mass in the airframe to absorb gasser type vibration.
