All motors comes with the model so its just the controllers you need
I use a Sanwa SD-10G 2,4Ghz 10channel system, it's a really nice radio system in my opinion. I have also set it up so the pump just idling when i not use the hydraulic, and then when i move the sticks the pump revs up.
I use regular 12V NiMh battery with 4000-4500mAh capacity, you can also use 11,1V Lipo.
Here is my machine
