Single Or Dual Motor Set-up?
Why settle for a 3 litre 6 cylinder petrol motor if you can easily fit a direct injected 5 litre 8 cylinder diesel motor with turbo and intercooler. Just imagine the sheer power! The torque is immense!
Well, I asked myself the exact same question when I started building my Axial SCX10. The nicest thing is that it is a really simple conversion. Sure, you need to buy an extra motor (both the same) and an ESC that can handle 2 motors. ATees is your friend here as they sell the Hobbywing WP-860, which is made specifically for 2 brushed motors. It is waterproof, has a 100% dragbrake, can handle 3S LiPo and uses “jumpers” to change the settings. You also need to get a dual motorplate and 2 identical pinions. So both 16T for example, but that’s about it.
Keep in mind that the amount of torque is going to be huge. On my SCX, every time I hit the throttle, my SCX tilts to the left, so I had to counterbalance it on the right. Also keep in mind that your spur gear will take a severe beating, so a metal spur upgrade might be a good idea. The same goes for the (middle) plastic gear in your transmission.
Last but not least are your driveshafts. The life of your stock plastic driveshafts will last shorter than with a single motor. So upgrading to metal driveshafts might be very wise as well. Boom Racing and ATees has you covered here. Metal spur and pineapple gears and Heavy Duty Voodoo Driveshafts, they have it all.
