I'm looking to buy a new motor for my 2wd Rustler, I am debating on the track as velenion (spelt that wrong prbly) and the castle crrations sidewinder 4, I have heard a lot about castle, but I just watched a fewvideos were they tore them apart and the velinion magnet was bigger, so I want different opinions on what I should get, and I love taking it out in the snow, paddle tires on the way!!
