My Giant Big Stik arrived yesterday (my test bed plane). Bought it on scratch & Dent from Tower for 112. Damaged wings (cracked ribs)which i fixed in a couple hours. Should be able to test the 25cc and above with it. I made a plate that mounts to the firewall yet has mounting hole for different size engines, so swapping will be easy. First to go on will be the 25.4 Stihl.
