I found it at a very good price and I grabbed it since I had it on my favorites for a long time. It's the first such large technic I make. When I started building the whole mechanism, each new connection excited me more than the previous one. The placement of the engines is extremely well thought out and clever. It is also a model that provides you with power functions inside and if you ever get bored, you can take it apart and build whatever else you want. As a final result, it is a good remote-controlled vehicle that offers plenty of fun with its operation, which is a lesson in itself for children. The only downside I find is that because its chassis is interchangeable (meaning it comes off easily and can be attached to something else), it opens very easily and so you can't grab it from the top to move it since it is connected to the bottom and the wheels only at the front of the model. An excellent choice since it has Power functions inside, although I believe it could have been a bit cheaper.
