I got my P-40 today (60 size with split flaps). I thought it was going to be wrecked when I saw the box at my door, but the double boxing worked and no damage to the plane.
Only detract to this plane is the covering, however, it is alot higher quality then what great planes uses. There is not a wrinkle anywhere. Paint does not scratch off eighter.
No hotglue in sight. Construction is excellently done. Retracts are installed and triple tickness ply used for mounting so they ought to last awhile. Plane is built from ply and cotonwood. full sheeted rib wing (not foamcore) All load bearing surfaces are ply and rest the cottonwood. Wood quality is alot better then the GP U can Do 3d. grain is finer so the wood does not stress fracture like the U can Do ribs can.
Web site warns of cowl warpage, but mine was fine and just slides right in place. Too much plastic is a concern. No problem now, but might be in future if it does not hold up. (should go to fiberglass like the cowl.)
Hardware on this ARF is even useable, the only other arf I have that I used supplied hardware was a Dave Patrick Ultamate.
Only gear I will replace is to use Robart horns, but thats a preferance, not required.

Overall great plane, seems much improved over the older designs. I was worried about VQ quality due to other posts, but have no issues based on this plane.
