Hey guys , any of you have the katana SR? i have one and i want to see what everyone thinks and what upgrades they have done , right now im flying mine on 4S and she does pretty good , i upgraded my servos to tower pro digitals and re-hinged it with pinned hinges , nice easy movement! i just ordered a 1100 watt motor which is overkill but i want the extra power , ill be running it on 5S with that motor and a turnigy plush ESC , i flew it at the black hills huckfest this last summer , everybody was suprised and i was using my turnigy 9x radio , using a JR 9303 2.4 now , ill be competing with it this next year hopefully!
