OOPS!!!!!Don't get the Mikado Swash Driver...thanks to my good buddy TOSH...I just realized that the main shaft on the rap 90 is 12mm....
the Mikado one is for a 10mm shaft
I'm not sure what swah drivers are available for the 12mm setups...you could always just modify the stock washout unit...basically you could just drill a couple holes and use set screws to hold it in place...my buddy did it with his trex 600 and it works great....
