Trumpeter provide the air-brake tanks on the Frog 7 (Baz/Zil 135 chassis) but no indication of hoses or cabling - any pics of the underside/braking schematics of this vehicle? I've been Googling this for 2 days with very few results!

Hello Ian,

I have a good few photos here, hope you find what you are after, I have no time to browse through now:

Make sure you search using Cyrillic letters.

This is for a Zil-135LM:

Thanks both - very much appreciated.

Has anyone else building this kit noticed that Trumpeter have forgot to add the 'outside' exhaust pipe on both engines? The manifold is there with the connecting hole, but it's not pointed out in the instructions and there's no corresponding parts in the kit. Not a biggie as it's well hidden inside the engine bay, but strange...

Something I have wondered for a long time: does one engine drive the rear pair of axles and the the other drive the front pair? Or does the twin engine driveline get combined into one at some point?

Was surprised when I saw there were two transmissions. I had expected the twin engine output to be combined at the bell housing and then go into one tranny like the twin engines in the Stuart..

No - left engine drives the left wheels, right engine drives the right wheels! There''s a video of one starting up and it lurches from side-to-side as the engines 'balance out'. If you look at pictures of the engines in the bay you'll see that it has one gear selector lever connected by a link bar to both gear boxes. the same for the accelerator (again missed by Trumpeter).
