You can make that rover 4wd by getting two rovers and rob the motors from it. Super easy a 10 yr old would have it done in ten min. I tested the rover 5 with 30 pounds on it with mine running 4wd, no more than 20 pounds and the rover is still fast.

@jstarne so would i be able to do it because im 10 lol

@daradu yes you should be able to do it , just have parental supervision when soldering and double check all your connections you have made with djs video before applying power. -Josh S

@jstarne1 dagu has a few models of the rover 5, including one with 4 motors and four encoders. i know that ez-robot can order these for you also, but im not sure if thats common practice. either way the 4 motor with encoders model is much cheaper than buying a second rover to pilfer parts from. -Miles

I have purchased the 4 motor option before. The reason i suggest the pilferage of parts is you have spares in case you mess something up or want to make a change ect. I know when I mod bots there is usually cutting involved lol.
