TManiaci (my dad) did the popsical stick thing to stengthen the cabane on my new hell raiser (the old one hit the ground and was too messed up to fix and ever fly again) and even in extreme, high G, 3D flying the wing doesnt twist and make it unresponsive. On my other hell raiser we did not build up the cabane and it had a twisting top wing in higher speed rolls and turns. I had a minor crash with my new plane a couple of days ago(i am A LITTLE more radical with my plane than my dad) but it is all well and flying great again after about 1 hour worth of repairs.
