Su-27 tires popping and pulling up in air?

[D4n]

Why are the tires popping when breaking for only 2 seconds? The brakes are far too strong currently.

 

Also, why does the aircraft pull up and go left-right-left-right in autopilot?

[BIGNEWY]

what speed are you applying the brakes?

 

have you trimmed the aircraft?

 

If you can add a short track showing the issues we can take a look

[Winston 60]

Tires blow out when you are way too heavily loaded and apply the brakes for too long. Try reducing the amount of fuel you're taking or reduce the armament loadout somewhat. Taxi slower and use the brakes in very short applications.

Ok, maybe you're right, taxiing with 40-80 km/h could be bit fast, but with MiG-29S tires NEVER pop...

 

Could the braking power be fixed, so that it breakes a little softer?

mig-29 currently still uses simple flight model

[bolek]

Wobbly autopilot at low speeds (e.g. < 550 IAS) is an old bug. It has been there ever since Su-27 got the new flight model.

 

It can also happen at higher speeds when the aircraft is not trimmed before engaging autopilot. This part may be not a bug but a real behavior, I don't know.

Why? What's unrealistic about current MiG-29S behaviour? Only that it looses too much speed when turning, right?

That's much too fast to taxi. Keep it under 35 Km/h and you'll be fine.

 

The real Su-27 has an automatic braking system (I suppose like anti-lock brakes on a car) that unfortunately isn't modelled in the game. To help avoid popping tyres when you're braking after landing dab the brakes quickly on and off.

The whole flight model is unrealistic, just like with the Su-33. Stall behaviour, ground behaviour etc., while the Su-27 has all those modeled correctly (pretty much as close to reality as possible).

Both, the MiG-29 and Su-33, will receive this treatment as well at some point.

I really don't see why ED doesn't add an axis assignment for the brakes on the Su-27.

Other aircraft have it: L-39, MiG-15, MiG-21.

This would solve all breaking problems.

Those are study sims, the SU-27 has simple FC3 aircraft systems

I seem to recall the real Su-27 has no brake axis, it's just an on/off button.

Might be wrong here but if my memory serves me right, that's why it doesn't have a brake axis in the game.

The L-39, MiG-15 and MiG-21 do not have one IRL either to my knowledge, so there's that.. all those planes (including the Flanker) have it as a button on the back of the stick.

FC3 still aims to realistically model hydraulics, physics (including flight model, engine model and whatnot) while providing easy to use systems. Hence, I wouldn't see a reason why they didn't add them to the Su-27.

Braking shouldn't have anything to do with it being study sim or not.

You dont understand Codefox.... The MIG-29 has no AFM YET. The SU-27 has. They are both FC3 aircraft. It has nothing to do with being a study simm or not. It's just a old flight model from the beginning of times. I'm going to love seeing DanielNL complain about the MIG-29 AFM when it comes out. Going to be lovely times.

That's exactly what I said..?

If it every comes out... And from what I heard flight physics will be even better then for MiG-29! :)

Don't know about the Su-27, but all the others have a brake lever similar to a motorcycle brake. So you can brake gently if needed. I don't see a reason why the Su-27 would be different, as a pilot I would definitely want to have full control over my brakes, but as I said I don't know enough about the Su-27.

Su-27 has toe brakes IRL.

[codefox]

Thanks for the clarification.

So, as I read from the other posts, it's actually perfectly possible to adjust the braking power on those planes (MiG-15, L-39, Su-27)?

[Esac_mirmidon]

According to the Su-27 real manual:

 

-Never exceed 50 Km/h in a straight line.

 

-Never exceed 20 Km/h in a turning less than 15m radious.

Yeah, especially ground handling with Simple Flight Modeling does not take into account A/C weight and tire friction, etc.

 

Can't wait for the remaining FC3 A/C to get their Professional Flight Model soon! :thumbup:

[cardboard_man]

 

-Never exceed 20 Km/h in a turning less than 15m radious.

This is the main one to follow. At-least for me its the reason i pop my tires turning onto the runway with a full load.

[D4n]

Toe brakes meaning what?

[mvsgas]

Toe brakes meaning what?

 

That you use the upper part of the ruder pedals (the part closes to your toes) to apply brakes by pressing on them.

Yes it's perfectly possible. And yes it's confirmed that the Su-27 has toe brakes.

[Chrinik]

Initially I thought it´s a troll post...why would someone complain about something that is entirely his fault, and ask for a fix when he just needs to fix his behaviour and be more gentle?

 

And yes, the taxiing in the MiG-29 and SU-33 are very forgiving because of Simple Flight Model...that will change.

I mean, in SU-33, if you have any forward speed, you can turn in place like a crazy person and spin around super fast.

 

But meh, it made me giggle.

 

ProTip: don´t taxi too fast and tap the breaks repeatedly (I still have them on W for reasons...)never had any issues since adopting to it. This keeps your breakpower low and doesn´t overstress the wheels even if you find yourself going a bit too fast, until they give us an axis to assign, it´s the only option.
