How do I adjust neutral position on Tx sticks back to zero?

[eturn23]

I plugged my DJI FlameWheel F450 into the Naza assistant software this morning and noticed that the neutral position of the Elevator control was somehow "bumped" to -85. When I push the Elevator up it maxs out at 880. When I pull it down it goes all the way to -1000. Rudder and aileron go to zero when I take my hands off the sticks and have full range from -1000 to 1000. Throttle also has full range.

I don't know how to reset the Elevator control on my Spektrum DX8 radio so that when I take my hands off the right stick it returns to zero. I tried re-calibrating the sticks in the assistant software but that didn't solve the problem. I think I have to make the adjustment using my Tx, but I don't know how to do that? Any ideas what might have caused the change? Yesterday all the controls were at zero (except throttle, which I keep at -1000 when I'm not flying).

Thanks for the help.

Added some trim by mistake? You may have adjusted your endpoints (look under dual rates, D/R). You have to move the sticks with a DX8 whilst looking at the D/R screen to see different directions of movement. Good luck! Plenty of help on the forum.

PS- How new are you to all this?

Ben- I am pretty new to R/C quad copters. Built my FW F450 in late June so I've been flying for about a month and a half.

I adjusted the Elevator trim so that the neutral position is zero, but that changes the range from -1000 - 880 to -940 - 940 in the Naza assistant software.

When I look into the D/R and Expo menu on my DX8 radio, the D/Rs are both set to 100 and the Expos are set to 0 as they always have been. There is a -2 below the lower left quadrant of the graph with an arrow to the right pointing at a -1 under the right quadrant.

The Aileron screen has a 0 - 0 below the graph and the Rudder screen has a -1 with an arrow pointing to a -1 below the graph. Could this be the problem?

I would like to get things back to the way they were yesterday where I have full range of the Elevator and the neutral (hands off) position is zero.


Thanks
