Are you using the HengLong electronics? I've never used HL stuff with this unit but my understanding is that it's a bit different than installing into a Clark... but I do know there are guides in a few build logs floating around.. ><

As for physical installation if it didn't come with a mounting plate, as some of them do for the Tiger, Panzer III, etc. then yea you'll likely have to 'make it fit'

...been trying to find you a good how-to but I've run out of time. Will check in asap!
