RE: weight VS stability
One of my buddys has a gws corsair about that same size I dont know how it lands yet as my 2yr old tried to catch it while it was coming in on the maiden and I had to ditch. We are flying it again in the am. Are there jogging paths at your park? also your guts will all fit in a $35 ez from gws or one of the biplane kits or if you go to the sig manufacturing site they might have a kavan blue devil left $90 this model flys very well and has some style. if not check the auction block and get something in a high wing for cheap and bolt in your stuff and fly the heck out of it for awhile then wreck it good and start flying the corsair again.
