Hey now, how come we Wedico modelers have to switch our king pins for Tamiya ones, to be universal? Ha ha. Why don't you Tamiya guys switch to the Wedico king pins!
Honestly, the scale does not bother me one bit. Some of the draw to the Wedico trucks, for me, was that they better match the die-cast Ertl models, giving us some great scale loads to choose from! Scale Art models are also a bit closer in size to Wedico, then they are to Tamiya also. Not that it matters much! I like both Tamiya and Wedico models, but like Lynn says, I'd much rather assemble a Tamiya! Box stock, they are more user friendly.
