Hi Carl,
I had a quick look at the specs that you sent. Your interpretation of the specs is correct. Run a little expo on cyclic initially until you get a good feel for the heli. On your DX8, just go into the menu by pushing the scroll wheel and then scroll down to D/R and Expo. Press down on the scroll wheel again. The one that normally comes up first is Aileron. If you look three lines down, you will see Expo. Scroll down until you have the block around the number values and press down on the scroll wheel again. The block will start flashing. Now roll the wheel to the right to increase the value up 30 (as indicated in the spec sheet that you've attached. The numbers in the block will now display 30 30. press down on the scroll wheel again to stop the block flashing. Now scroll up to the first line that says Chan : Aileron. Press down on the scroll wheel again to make the block flash. Scroll one click to the right and you will see that it now says Elevator in the flashing block. Press down on the scroll wheel again to stop the flashing. Now scroll down to the Expo value again and press down on the scroll wheel again to make the block around the numbers flash. Once again use the scroll wheel to change the values to what your spec sheet stipulates ( 15 15 ). Once done, press down on the scroll wheel again to stop the block flashing and use the scroll wheel to scroll all the way up to "List" again. Click the scroll wheel to exit to the main Function list again.
Pitch is pretty much as you've said. Just follow the spec sheet. You may want to tweak these values to your own liking.
If you look under the helicopter help forum, there is a "beginner" help section where Tony has made some recommended initial pitch settings. It will give you a good starting point.
Something else you can try is to create a new "ficticious" heli model on your DX8 and play around in the menus to get to know the workings of the DX8. This way you will not screw up your actual heli programming.
That was quite a mouthful and I hope I made some sense.
What I really like about this forum is that you will get lots of help. This forum was my savior with all the good advice.
