Mach7, thank you for the "dimensional check"! It appears that the Alliance kit is the same size as the Monogram kit and indeed, that is alluded to on the Federation Models website:

"This 1:32 scale
accurized resin kit has 19 parts and is 11" long. The correct canopy, positionable flaps, and front landing gear make this model a show-stopper. Decal sheet, assembly, and painting instructions are also included."
One point not mentioned is that the main 'fuselage' between the two 'spikes' was lowered so it is centered on the spikes, when viewed from the front.
Strangely, no mention of the 'Buck, Wilma and Twiki' figure set that they carry. These figures are definitely 1/48 scale, and as Buck is sitting with a flight helmet on, I wonder if they might have really considered the Thunderfighter to be 1/48. Looking at pix from the show, however, definitely indicates the craft was smaller than the model would be if it were 1/48, so 1/32 does indeed appear to be the model's scale. The 'Monogram ne Alliance' models dwarf the standing 'Wilma' figure in a way not see in the show's images of the starfighter prop... ah well, that is what it is...
I will avoid diving into *that* particular 'what is the scale' rabbit hole at this moment... ;^P
