RE: setting pitch
Sounds like you got some linkage problems to me. If you converted to the 3d setup your swashplate to seesaw arm needs to be adjusted. When your links are set up right with your pitch curve mid point set to 50% and your stick at half (to obtain center of the servo travel) you should be at 0 deg pitch. When you have this set you will be able to get 23 deg total travel with no binding. -10 on bottom and + 13 on top. After you get your links set up then go into the radio and set up your pitch curve. The pitch suggestions that bdphil made are a real good place to start. Best thing to do is check all your links from the servos up. My guess could be wrong but sounds like you've got something out of adjustment. By the way after you get it setup you might have a little more or a little less pitch than what I've mentioned depending a lot on your servo travel. Just a tip I've picked up,,never use the radio to try and fix a mechanical problem.
