The problem I described on the YA-47...the indicated CG was just not correct for that plane...We moved it forward one half inch, added weight to compensate, and it flew like it should with only a Quadra 42. I, too, have a GS TF P-47, around 22+ #s, with a G-45..With a 1900ma 6 V battery over the tank, it balanced to the plan, and the throws set slightly above plan recommendations... A beautiful handling plane, even when not using the big flaps.. the trick is to keep about 1/3rd power, and FLY the plane to the numbers.., flare, and let it sink on the mains, the big cowl, prop, LG, and flaps will slow it down quickly with the nose up, as speed drops off, the TW will come down.... when three pointing, this heavy plane will still give the LG and TW a pretty sizable rap when it drops....
