Last week end my father and I went to University of the Philippines and flew the jas-39 designed by jetset44.
77% of the original plans
RCPB 24g 1500kv motor with a 7x5 apc type prop with a max thrust of 500g
The first few flight ended with crashes due to a lack of experience with this type of plane and a far too aft CG. I fixed the CG and rates for the elevons and canard and finally it flew but it now had a very forward heavy cg and had to keep pulling up. Then as was turning to land, i lost orientation and crashed it into a tree... and good thing these guys came along..
