Can any one tell me the wing area of the Su31 from Phoenix? I just finished mine and have a 61 on it and had to put 6oz on the tail to balance it out, now its close to 7.3lbs dry. I've read that normal flying weight is 6lbs, and it lands hot with that. I'm trying to figure out the wing loading but cant find the wing area anywhere.

Its really easy to measure the wing area. Unless I am not understanding it. Have a look at this. www.mediafire.com/ Not sure whats the easiest way to paste an image here so I guess I'll just use media fire until someone tells me otherwise.

By the way I built mine totally stock and am using a .55 AX. My dry weight is 5.5 pounds. And yes it lands hot if you don't balance it correctly. Right now with the battery positioned ahead of the CG and with a big aluminum spinner and the cowl on it is a pain to land on our short runway. If I take off the cowl it lands nicely. I need to put the cowl back on and move the battery back until it balances in the same place as it does now without the cowl on. No added weight, the cowl is on, and it lands nice and slow. I would assume that you already tried moving your gear around to balance it instead of just chunking weight in the back..?

Oh yeah, it hovers at 75% thrust as well. With a 12 x 6 K-series Master Airscrew.
