My diff setups will not work for you guys racing in TCS events, as I use the TOP Sabre FWD car oil gear diff, built per instructions with Team Powers 400 000 weight gear oil. Filled to just above the diff cross joint. To use this diff you need to add the two red shims, (come with the diff), either side and then add some 0.3m and 0.2mm shims. Make sure you still have a little side to side movement within the car. I also spray Nulon silicone grease onto all of my gears, which makes the drive train very free. Good thing is it does not fling off.
Other thing to remember on the new MO5 V2 is to place some tape over the gap in the top of the chassis and battery compartment, otherwise, if you do not place the tamiya anti-wear grease as directed in the instructions, your gearbox will fill dirt and cause issues.
I agree with Granpa and Orlando, that just putting someones elses setup on your car will not make it handle the same. We all drive differently and have our transmitters setup different. Getting your radio setup correctly is just as important as having a gun setup.
Just my two cents worth.
