Throttle channel in Mission Planner loses resultion

[GoogleCodeExporter]

No matter what Throttle gain is set to, the full resolution of the throttle 
channel is not passed to the simulators.

This may be due to this line in Simulation.cs

  throttle_out = ((float)MainV2.cs.hilch3 + 5000) / throttlegain;

The result is either available throttle range is compressed into the middle 
where 0.0 and 1.0 are far above the bottom, and below the top, of the actual 
rang, or if Throttle Gain is set too high, it maximum throttle is not reached.

so what are you actualy saying?

throttle is scalled from 0-10000, why are you scaling throttle from anything 
but the default?

Throttle is by default scaled by 10000, but then the lower 1/4 and upper 1/4 of 
the range of 0-100 reaches X-plane as 0.0 In other words when ArduPlane sets 
the throttle to (10%), X-Plane sees 0.0. When it sets it to (90%) X-Plane sees 
100%. 
ch3 out might be set in eeprom to be 1100 for 0% and 1900 for 100% for a 
particular radio. 1100 thru 1300 all maps to 0%, then it increases linearly, 
and tops out way below 1900.

Increasing to 15000 helps, but it is still impossible to get from 0-100 to map 
to 0-100 in X-Plane.

Sorry if this isn't clear. I feel the reason is the line of code in mission 
planner that I included with the magic number of 5000 in it.

Hi Justin, verified the issue
and the fix is this
throttle_out = ((float)MainV2.cs.hilch3 / 2 + 5000) / throttlegain;

hil / 2 = -5000 to 5000  + 5000 = 0.0-1.0
