M577a2 question

Morning all, I’d like to build an ODS era M577 and having read some comments on other sites, the Tamiya M577 isnt the best tool for the job.

Comments suggest using the Academy M113a2 as a base with the 577 hull. Can anyone explain the reasoning for this? Ive got a Tamiya M113a2 but this may have flaws, but what are they?

I saw Gino posted re his conversion of this kit but the links no longer open.

Thanks all in advance.


The Tamiya hull is really an M113a1 hull and is less detailed than the Academy hull. I used a Tamiya hull on mine. It take quite a bit to bring it up to speed.

Here is my build at Finescale Modeler.



Legend now has an M577 Detailing Set as well.

@HeavyArty Yea, what he said. Honestly, the Tamiya kit, old as it is, is the only kit of a 577 to date. They just added parts to their M113 kit, so it is real easy to just add them to the Academy kit, which is much more accurate. For after market, besides the Legend set, the is a PE set from Eduard. Good luck!

Thanks Gino

From what you and Ken have said I’d better find an Academy M113. I’ll study your build log as it seems there’s a lot involved.


Cheers Ken, always appreciated.

I am always amused when people say that the Academy kit is the better M113. It isn´t. If you can affort it do the following:

  • buy Tamiya M577 and AFV Club M113A1.
  • add Legend Production M577 conversion
  • and finally put Model Kasten M113 tracks on.
    Then you have a perfect M577 kit at a 120 Euro pricetag.
    And if you are really crazy, you can build the generator from scratch like I did. :grin:

I agree, the AFV Club version is better detailed than both Tamiya and Academy’s offerings, but, it is also an A1 and will need all the same updates as the Tamiya one. At least Academy’s M113A2 has some of the updated parts; A2 engine deck, exhaust flapper and guard, second shock, second vent for the heater, proper trim vane handle, etc., etc. I think it is a better starting point.

I agree with all the above plus (to me) the detail on many parts - trim vane, road wheels, jerry cans, etc. is better, and it has the correct (A2) engine and interior parts. I also like the accessories that come with the academy kit.

Having studied the above I’m putting this project on hold for now.

Ive got the roof in the Tamiya kit, but need stuff from Academy and some AM suppliers.

So, back to the current build, an M813 using RMs M800 tractor kit - pending RM sending me some missing parts.

The M577 project is back on track, SWIDT? Legend conversion, Academy M113 and R-Model tracks ordered. Tamiya M577 is there for its roof.

This wont be here, or built, for awhile but hey ho its in the stash!
