Hey, thanks Ron, The two parts that I really found difficult, or tricky were the p/e etch intakes on the side. Those took a bit of prefitting and planning before actually glueing. The whole assembly kid of interlocks with each other and its hard to find the "right" steps to assemble it in. The other was the ammo rack. Some very small fidly parts. In order to fit the correct amount of shells in 1 bin, I had to use all the parts Dragon supplies for both bins. Just placed two side by side instead of one as Dragon suggests. The only drawback is one bin has to be closed. Other than that, everything else was pretty straight forward, but a better improvement than the original issue of the Nashorn. Though, if ever I build another I'll surely go for the Lionroar or Voyager p/e sets.
