The construction took a few hours and a lot of fun (my now about 40. LT model) ... error-prone locations are not noticed. Only criticism: if you can down the tailgate with the landing gear extended, this does not reach to the ground. All other functions and the design per se, however, are very well done! A special praise deserves the very easy access to the battery box, if the battery / batteries should be times empty: just the two major page elements (with the "windows") remove, dissolve 5 pins, Box slightly pull forward to the last holder to solve and even the box can be removed. The cable is long enough so that you do not have to assemble solve beforehand or connect after installation.
