I would add right thrust too. These small micro planes have a fast spinning prop and if you build it light, lotsa prop torque. The HH UMX planes have very obvious down and right thrust angles, so a little right is good. 21" may be a little big for the p51 gear,...unless you can get her to weigh approx the same as the UMX version. Otherwise, 17-18" with a little wider on the wing and elevator chords perhaps? But of your going profile, 21" may just work out well. Keep it light and use glue where needed. Don't When I started building I always overdid it. Then thru time, all those places I overdid, never really needed any...haha!

Best of luck! And report back! On a side note, my Sbach is still around and perfect for a slow sporty flight when 3D isn't in the mood. Tho she can 3D, I just love watching her fly patterns with those destictive colors!!

I did re-size to a 17" half was just too small.I am gonna go on and do a big one too.Just gotta get the electronics.Re sizing was an adventure I did it by accident on this.I found a set of old plans for a balsa Storch; well 39 pages later I got plans to build one as big or bigger than the cover plane on RC Airplane.....Needless to say that one won't be built in the foreseeable future.I did get one the right size this morning and I think I have it figured out now for repeatable success.
