I have a Bobcat 50. yellow

1) instructions:
1a nonlingual are of poor quality photos
1b CG location was WRONG, very wrong about 6" instead of 10.1"
2) landing gear wire is soft, bends to easy, no temper = no strenth
3) landing gear mounts:
3a poor design jusrt one edge glued to a rib, and one edge glued to the trailing edge
3b poor workmanship, just a spot of glue holding the gear block in....it failed
4) covering material of poor quality, trim layer blew off in flight some color still on wing.
5) front blind nut mount plat came loose from tail boom IN FLIGHT!
6) Red paint was discolored on fuse near engine.
6) fuel tank cause fuel to faom up. no padding just stuck into the formers inside the fuse.
7) motor mount blocks were of soft wood ad began to fail.

I would guess that no "beta" models were produced from production tooling and no test builders/pilots were used.
