It may actually be my fault with the mt410 as I was under the impression if I didn't beat on it, I could run it stock. To get it to where it needs to be imo, it needs another 200 spend on it, which brings it to £600. with no wheels/tires/body. It almost seems, imo, its a 1/10 truck and running gear, that can take 1/8 electrics. Again that's my mistake, as the clue is in the name, MT410. The chassis has to much flex, bumpers are useless, and its just not strong enough for the price point.
I remember seeing the EXB roller, and in hindsight for me that may have been the better purchase. How are they holding up generally in regards to the chassis bends etc? When you say may need 6s, is that due to weight etc?
