Throttle signal jumps

Posted by Sebastian Gralla on December 7, 2011 at 10:51am

I have switched today to the new 2.0.56 code (was running RC1 before, I know, old code... :D)

I now have a problem, my throttle signal (from reciever) is normal until 1500, when i push the stick a little mor up, it reads about 1800, no way to get values in between there.

so the copter behaves like these values show: i can't get it to hover, it's going down, or up pretty fast.

recalibrated several times...

It worked on RC1, have not tried other versions in between.

my hardware:

APM 1.0

Orange RX 6Ch reciever, 2.4ghz DSM2

any suggestions?

Ok thank you all, I solved it.

seems like my transmitter jumps to maximum throttle when trim is not centered.

solution -> trimmed it up a bit, and now it's working fine :)

Do you have any mixes setup on your transmitter for that channel? I am not familiar with your radio TX, but maybe you have the channel assigned incorrectly. When you calibrate in the Mission Planner, do you see the throttle smoothly climb and fall as you move the stick?
