DX8 throttle response
 

I have a DX8s on an airplane and I don't have any throttle response till i get to half throttle I know its just a setting i don't have right

First of all, just try switching to an unused Model Memory and Reset it to Factory Defaults. Bind the receiver to it and see if the Throttle Response is the same. This will ensure that all Trims are at Neutral, no Throttle Curves are set, no Subtrim is set, and no Mixing is enabled.

Electric? Or gas/nitro?

Pull up your servo monitor screen, that should be your first stop for troubleshooting any issue like this.

I changed my throttle curve that seem to fix my problem

A bit of quick research showed that the speed controls I have are consistent.
The normal servo control pulse is between 1000 us (0%) and 2000 us (100%). The speed controls start the motors spinning at about 1100 to 1150 us.
a "factory reset" of the transmitter settings usually sets the defaults to about the normal servo pulse range for 0 to 100% travel.
Some speed controls can be set to different ranges, and some have a "learn mode" that adapts them to the transmitter at power on.
You might find a couple of little yellow boxes at your friendly hobby shop, or a model show. One is a digital servo pulse readout, and the other a servo tester.
They work quite well for testing speed control motor combinations. I also use a watt meter from Bantam.
