Setting up the 744 with FSUIPC?

Hi all, I've got a registered FSUIPC v3.7 for FS2004 and it seems a great program, but I'm just looking for some advice from some of you who may have used it on how to get the best out of it with regards to the PMDG 744.I assigned the four middle levers to engine 1-4 throttles using FS. I tried to configure them in FSUIPC. Setting the max was easy, but setting the idle and reverse proved a challenge. As anyone who has the quad will know, there is a rest spot for each lever, and then there is a "click" spot behind it. I try to set idle to the rest and reverse to the click, but it doesn't work, reversers automatically come on even at the rest. So I see that there's an option to assign reversers to another axis, so now I'm thinking that it might be easier to just assign them to one of the three free axis on the CH yoke. But I cannot figure out how to disable reversers from the separate engine controls, and route them to the CH yoke instead. If anyone could help me with this I would be very grateful!!Also, what should my settings be for the Yoke, Pedals and Throttle Quad in FS Sensitivities? So far I have them all set with all values Sensitivity to the max, and null zones zero. Is this correct? If anyone could clarify the whole sensitivity/null zone issue too it would be great because I'm not entirely sure what they really mean, thanks!Ok, thanks a lot in advance for any help!
