Aermacchi MB-339 Pitch Stability Issue

Featured Replies

Nice airplane but, when I move the elevator up it bobs up and down rapidly. Same when I try to pitch down.

I'd like to try different numbers:

[FLIGHT_TUNING]
pitch_stability =1.0
roll_stability =0.1
yaw_stability =0.1

What numbers should I edit?

It's not bad, but no Lotus L-39. I'd love to hear what a real one sounds like from the cockpit because I'm not that enamoured with these engine sounds. No blurry scenery here. How does the plane get the blame?

One last thing. Has anyone managed to stall it? Throttle right back, stick right back and air brakes hanging out and still it flew along at 100kts. Refused point blank to misbehave!

Still, I've spent more on worse. 🙄

Good question. I've never seen blurry scenery until I started testing this beast. It's really nice, but I'm wondering why my ground textures have lost their sharpness. I'll go back to my Mooney and see if textures are still blurry.

I have a feeling that it's the speed. Maybe not since I've flown the A320 & 787 with no blurries. Maybe never noticed them.

No problem with the sound. I actually have an immersive sound system.

Update: Without my knowledge the BING data was turned off. That's why I seeing blurry default scenery.

Well, the engine sounds the same whether the canopy is open or shut.

That little bit of extra immersion, where it gets perhaps a bit quieter once you shut the lid, would be nice.  Of course, if the real aircraft has no change to sound, then hey I'm all for it staying like it is.

I'm starting to find out that Dino doesn't like to provide support. If anyone knows how to smooth the pitch, please let me know. Using FSUIPC6, the aileron and rudders behave properly. It's just the pitch that is not smooth. Default MSFS controllers are a joke. They are terrible even when  following the recommended setting on the FB page.

no way I'm knocking back the curves that far just for this AC...

I was thinking of buying this plane, but when I saw the recommended sensitivity curves.... Nope, not doing that for one aircraft.

I know it's possible to properly tune the control sensitivity to work with default linear curves, because Robert Young's Bonanza Turbo mod does it perfectly.

FSUIPC allows per-aircraft settings, or at least it did with FSUIPC6

As for FSUIPC7, maybe it can do this thru the Control settings?  If so, I haven't found out how to do it.

I mean FSUIPC7 beta and it does allow the user to specify profile specific.

It's no Lotus L39 but it's still fantastic. I'm going to have to hope that Dino fixes this pitch issue right away.

BTW, I did see the pitch issue in a review video. You can clearly see the rapid oscillations with an external view.

Not sure it's in that class. Nice enough though. It's main problem in my view, is that it has the L-39 to live up to.

The Lotus Sim L39 was ahead of its time. In P3D you could see the aging external textures but easily overlooked because it had some lovely VCs, VC lighting was superb, landing lights like no other, VC rain effects, and it flew like a dream. Added sounds from Accusim also helped especially when deploying the spoiler.

This one is way ahead in many respects, especially in the textures. Just beautiful inside and out. The lighting is excellent and aside from the fixable pitch stability issue it's fun to fly and a challenge to land. It has enough systems to keep me busy. I'm going to enjoy this one for a long time.

In conclusion, I'm very happy with my purchase and IMHO is a fantastic addition to my hangar.

This aircraft is MUCH louder than any of the others in my library.   I can't even hear discord  in the cockpit,  or in chase.
