I have a 2 plate quad with the equipment on the top plate. It sounds like I should measure from the IMU and PGS to the middle between the two plates. Do you measure from the bottom of the IMU and PGS or from the top of them.
Thanks for the help.

You need to measure from the actual center of gravity on the Z axis. Where that is will depend on what you have under the quad or more specifically how much weight you have below the lower centerplate, the greater the weight the lower the CG will be. To start with you can assume the CG to be the center of the bottom center plate, you will enter negative numbers for the Z axis for both the IMU and GPS, when measuring the distance for the IMU, measure to the center of the box both horizontally and vertically, same for the GPS pod. It will fly using that as the CG but later you may want to fine tune it some depending on what you're carrying, getting it as close as possible to actual CG made a difference on my big hex, not quite as much on the smaller quad.
. Can someone recommend a rod length that seems to work best and do you just use 5 minute epoxy to put it together. I have a 2 plate quad and the equipment and GPS antenna will be on the top.
Use the longest one in the kit, the GPS has to be as far away from the IMU and control box as possible for it to work its best, too close and it will take anywhere from 5 to 10 minutes to get a lock. I used gap filling super glue with a shot of kicker to put the carbon rod into the aluminum parts, no problems so far, epoxy will work too.
I read in the manual that failsafe should not be set lower than 10%. I have a DX8 and a AR7000 receiver. When I try to bind with say 25% throttle it will not let me and gives me an alarm because the throttle is not a 0. Has anyone else had this happen.
I had the same problem with my JR 11X. What I found that worked was to set the RX in bind mode then turn on the TX with the throttle down, quickly move it to half way, then hit the bind button on the TX, worked for me don't know if it work on the DX8 but worth a try.
