Sadly no, only thing I know is downgraded radar range. But wait, seems Soviet radar had about 5 modes, WP` had only 3. And Yugoslavian/Serbian 29 is not WP MiGs, they were 29B afaik.

The export USSR avionics were supplied with a simplified counter-countermeasures system. But the radar range did not change.

I was wondering have you compared the radar ranges given in soviet, german and yugoslav manual as well as number of radar modes?

[AeriaGloria]

Yeah, and only missing radar mode is SP which even domestic models were made without sure third batch. Radar, TP, CC, Helm, Opt, Fi0, toss, 6 modes!!

 Every manual I have read fire all the sub variants sure identical radar range

The question is not the R-27ER or ET, even if everybody talking about their compatibility. 

The point is: the MiG-29 9.12A and B versions, so as the 9.13 only had the R-27R. There were no R-27T for the MiG-29 serial production versions. The longer ER is a way different question, since their length simply did not allow to use the flap. Here is a ukrainan 9.13:

Here is a russian MiG-29SMT (which is very far from the 9.12):

But the 9.12A and B had no these weapons, or if they would have, that would be only the ER. The T and ET belongs to only the Su-27 family.

The flap isn’t blocked, we’ve seen 9.12/13 fly with R-27ER just fine. It’s very close! But apparently works. Your second picture shows it with ER and flap down. SMT doesn’t change the wing. It’s not that far from 9.13.

R-27T was only a matter of procurement. APU470 is a cooled rail. Asked a MiG technician - yes it could use the T, no they didn't have them delivered. Model - baseline 9-12. Photos of APU470 preparation TBD.

Regarding Su-27 not being able to launch it from AKU - it's not about loosing lock, it's about AKU doesn't incorporate cooling system in the first place.

maybe we can remove the bottle since it's mass is stated in the manual...

Yup, and place a checkmark "Pilot is on diet"

This later is difficult, since pilots are entitled to their flier's supplement.

Even the first photo of a Ukrainian 9.13 shows an R-27ER, from what I can tell.

Yes, you are right. The SMT is actually a 9.13 with a bigger back and some avionics upgrade, additional refuel probe and a modernized cockpit. Butt all the delivered SMT were actually a refurbished 9.13 airframes. And yes, it seems the flap was not blocked, my mistake.
