Rockets drag before and after firing.

It is the same. 

There is no speed change after firing rockets and you seem to permanently have the drag associated with them.  Bombs and fuel tanks appear to work normally.

Thanks, wanted to evaluate this also. Did a flight yesterday and after trying to land after firing rockets, I needed so much power to maintain flying speed. Will try to get a track or two when needed.

I second this. I tested some missions and this is true. 
This aircraft has problem with payload/drag/speed before and after firing rockets (don't know HVAR or Tiny Tim)

Hi @-Rudel-, sorry for the ping, but wanted to fill this thread with some tracks.

 

Not totally scientific, but this should show the difference.

Caucasus mission new, Corsair set to 3000ft air start with 50% fuel.

In both scenarios I set 2300 rpm and 34 in MP and didn't change cowl flap position after spawn. Descended to about 2700 ft.

• One short track is without wing rockets and automatically without the stubby rocket pylons. Speed achieved in level flight was about 214 kts IAS even in a slight climb to 2800ft.

• Second track starts with eight rockets attached, speed at around 2700 ft was around 181 kts IAS. After firing all rockets and keeping 2700 ft, speed went only slightly up to about 185 kts IAS (don't know if this was just a bit PIO around the 2700 ft mark or not).

So questions persist:

• Are the stubby pylons so draggy? How much difference do they make compared to no stubby pylons?
• How much faster should the F4 go after firing eight rockets both losing the weight and drag of them?

Thanks for checking

Jens
