Hi all, i did get one of the 112" beavers in army colors, plane seems to be constructed quiet well, firewall is ~3/8" thick and capable of supporting 50cc engine, 3W48 fits in to the cowl quiet nicely, there is ~6 in space (depth) for the engine, total kit wight is 12.9lb that would suggest to me final weight of about 20lb not as indicated on the box 14lb.
I originally purchased it for sailplane tug and belief it will do the job nicely.
