Bruder Mack Half pipe dump truck

[RcBruder]

So i am looking forward to building a RC dump truck and saw a Bruder Mack Granite Half Pipe dump truck for about half the price. Some sort of sale and its brand new! I was looking for parts and as i have a bruder semi already and the rails seem to be pretty strong, i am going to keep the rails as they are until they give out

Parts I am looking at so far are:
Double rear axle with built in motors from Magomhrc

Front axle with built in motor from Magomhrc

Then for lights i have a offbrand truck light kit from who knows where.
45A Speed control so each motor has enough power.

I am not sure if its a good idea or not but i was thinking to put all three motors to the one speed control?
For steering i am using a Traxxas 2075. Its a high torque servo and im gonna need the power! I dont think im missing anything but i hope to have pictures soon! I have ordered the truck already and am going to be purchasing the axles soon! Please let me know if the parts i have listed will be good for this build!
