ok it was not easy , but dobeck now agree the uforce800 and the zforce800 share the same motor, the said they were going to add the uforce to the application list their part number is the same as the z800 and is 8320128 they gave me a$25 discount for being a forum member , bought a safr A/F kit at the same time but no discounts on them. i will report the impact these have on my uforce when they arrive
