Is there a noticable difference between the I-185 M-71 and the I-185 M-82? The only difference that I've noticed seems to be that the engines are different, so, which model is better? Thanks

The M-87 can take bombs, the M-71 can not.

early one is the cats pants
bigger motor, faster, climbs better but both are feeble even with 3 stage up beyond 8K
great plane, one of my favorites online

I was wondering about flight performance differences mainly, and yeah the I-185 is one of my favorite planes too. It's pretty fast, has good manuverablity and it's got 3x20mm cannons, which is pretty good for a fighter plus it also can carry rockets which are way good for taking out bombers. Or vulching people. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

I think one of them is optimized for low altitude, one is best at high altitude. I don't remember which engine is for what.

The difference is in engine. There are two versions of engine: M-82 and M-71. M-82 or AĆ -82 (ASh-82) is a well known powerful radial with output of about 1750HP used in La5/7 family, while M-71 is even more powerful engine with output more than 2000HP. I-185 was firstly planed to have M-71, but due to unreliability and overheating problems, they substituted it with good ole M-82.

I-185 M-71 is a better performer by a considerable margin. Just don't forget to fiddle with it's 3 stage supercharger. It is a true uberplane.

What he said plus there is difference in weight: I-185/M82 t/o weight was 3328kg and I-185/M-71 - 3735kg. Naturally that had impact on RL handling as I185 had the sae wings of 15,53m^area. So I185/M82 wingloading was 214kg/m^2 and I185/M71 240kg/m^2, i.e. equal to Fw190A9. Naturally I185/M71 isn't overmodelled in turning http://forums.ubi.com/images/smilies/mockface.gif As much as La-7 climbing was tuned down to realistic values in 4.03 http://forums.ubi.com/images/smilies/winky.gif
