I like this. I have been converting the TF GS ARF to B model for about 10 years. The B model flies better than the D model. In all, I have built or owned 8 TF ARF and kit planes and recently have switched to the H 9 Mustang. The flying qualities of the H 9 Mustang are better all around than the TF plane but the H 9 plane has quality issues with the wing that make it hard to justify buying a third H 9 D model to convert to a B model. The fiber glass fuselage available for the Jerry Bates Mustang really looks nice. I will be watching your build and may just go ahead and order all of the parts and get started. I used the Robart pneumatics in both of my H 9 Mustangs and with a modification to get much more reliable main gear cycling, they work very well. You might want to try the tail wheel retract that Robart makes for the H 9 Mustang, it works properly out of the box and is scale, retracting forward like the full size.
