P39D&Q climb not matching charts

[kroker]

Both P39 models climb around 100-150fpm less than indicated by the in game charts, at the listed weights. For example, the D never gets over 2500fpm where the charts indicate 2600 or so. WEP climb in the Q maxed at about 3125, but should be 3250. Mil power climb for the Q is off similarly.

DT shackles or clean?

Also, what do you have the auto-climb speed set to?

That was clean, with no DT equipped on spawn. The Q had the 4x50cal option as that is the only way to make the specified weight.

Climb speed was the default from using alt-x, 162mph indicated. I tried some other speeds thinking the default speed might be off. Climb rate was better at some alts and worse at others, but was always less than shown in the charts.

The altitudes I tested were around 3-6k, where climb for the 39 should be at maximum. I didnt check any higher alts.

Be sure that the weight of the P39s match what is indicated in the climb rate charts. If the weights match and your climb rates show otherwise, then you may possibly have a bug in the P39 autoclimb.
