There is only one limitation that affects the functionality. After my son and I to stuff with motorized mini motors, remote control module and battery pack have, we had to have noticed that that the trolley is so stiff that it can not be moved from ordendlich Mini Motor. We did it after some Fieselei connect a power engine to the trolley. For this one must now say that the Power engine ample power has to move the trolley, but the two coils, in which the cord is wound for the trolley are placed only on the waves and not ordendlich fastened, which -for fast forward and retracting the cat the cord quickly ausleiert and often needs to be tightened. At this point, a constructive remedy would be helpful.
Luckily, however, is a highly modular, so everyone has the opportunity through their own ideas to improve the system.
All in all, a really great model, I had as a child and a fishing technique crane which was not comparable but with this model.
Really great and inexpensive despite the high price
