This is a nice kit with one major flaw. The main beams have slots that allow them to interlock. However, the joints are too tight causing the beams to warp during assembly both across and lengthwise. I caught the lengthwise warping and made the slots larger which took care of the problem. But I completely missed the warping on the cross beams before glueing, ruining the model completely. However, the kit is nicely cast requiring very little flash clean up and fine rivet detailing. Just be sure to file the slots on both the short and long main beams.
