That's news to me, it's not by design that it's doing that.  I'm not sure what's causing that.  I'll take a look at it before the next version.

Pyro,
     I am glad to hear from someone at HTC on this matter. Hopefully its a simple matter and thanks for your attention.

To add a little info:

The speed vs GPH appears to related to true airspeed. Like Ive posted before the altitude effects can be ignored. It appears as the model sits this is already the case. I airspawned at 30,000 feet and the GPH was identical to the ground.

Whels,
    While you brought it up it was not gone through in much detail and some of the few facts presented were false. The ME-163 was able to refire its engines in flight but it was not a normal procedure. In fact you only needed to supply fuel to the combustion chamber and they combustion process started itself. The GPH did not decrease as a function of fuel level. The fuel system comprised of two sets of pumps, a primary and a inducer pump. The inducer pump prevented cavitation in the primary pump by increasing the inlet pressure a small amount. The primary pump supplied the majority of the pressure to the combustion chamber. As long as the inlet to the pumps remained covered by the available propellant the the pressures were constant. As previously stated the altitude effects the thrust output by a small margin. Hopefully with a little explanation and some anecdotal evidence we can at least get thier attention.

hehe hard for me to  go into detail as i am not a engineering guy or aerospace person. But 4 years ago i knew the GPH vs speed wasnt working correctly, and posted a ? why, but never got any response :(. heh now Pyro says news to him, guess they dont read the boards much lol.

Whels,
   I cant really comment on that because I am not Pyro. Lets just be glad its getting fixed or least looked into.
