Wingtip missile drag

[Cab]

Looking for a sanity check:

After firing one of the wingtip missiles, does anyone else feel like the drag from the remaining missile is too high?

[Kayos]

Agreed, I don't think it should be that much.

[Cab]

Well, that’s it then.

100% of DCS respondents agree the drag of a single wingtip missile is too high. 

[Krez]

The drag is too damn high!

I was planning to test a variety of planes to compare to the F1 because I think the F1 suffers from FAR too much missile drag on the tip missiles. Glad others think the same.

The F1 often didn’t fly with empty missile rails because of the impact on drag- although wingtip missiles and rails improve high alpha stability.  It’s a relatively small jet, any asymmetric load has an impact

Maybe. But it seems significantly more pronounced than in other small jets such as the F-5. 

Here is a track of what I see:

The question becomes is the F-5 under representing the asymmetric load or is the F1 over representing.

Yeah I've noticed that it does seem to be excessive versus other modules, but it might be right. I have yet to see actual data either way.

I also found that payload drag, not only wingtip missiles, seem a bit high. Applying trim once you fired a missile is really not optional.

I've tried some loadouts at 25k ft alt and its a big difference when you're clean and with any loadout. Even just wingtips and missiles on it. As soon as you jettison the plane do accelerate fast. It stuck around 400kn IAS with any loadout in general.

Yeah the mirage is pretty sporty with just the wingtips, surprisingly so given its overall low TWR, but I guess its pointy. But yeah any sort of other stores slow it down considerably.

This comes with other discussed flight model "issues", like lift at low speed, yaw stability etc. These are fine tunes that will be (hope so) adjusted over time.
