Bruder 8x4 conversion(hopefully)

[Sloan]

Hello all,
first off I would like to say hello to every one on this forum I'm new to rc equipment and I'm in dyer need of som help to get me started.
Basically I'm looking to convert the bruder merc 8x4 dump truck but don't have a clue what parts I need or where's the best place to purchase them. I'm guessing a motor gear box drive shafts diffs axles and wheels not to mention hyds for tipping mechanism if it is hyds, but how do u know all this stuff fits together not to mention how all this connects with the radio handset.
Sorry for not having a clue but I'd be really gratefull if someone could point me in the right direction.

Also I'm not sure if this post is in the right place so appoligies if it's not

oh and happy new year

regards
Steven
