Well, the final piece of the puzzle has fallen into place on this thing. Took some more modifying, but I got a motor in it now, and she fits like a glove!
Back when I made the new plate for mounting the center diff, and cut down the RCM mount to get the center bones leveled out so they'd go through Gregers' chassis supports, I'd completely overlooked the fact that lowering all of it down into the chassis, created a problem
So, since I'd already done all of that work, and removed material from the RCM mount, there was really no turning back. And since the 1520 was so long, I had to use a shorter motor. So I modified the upper deck
to accept a Tekin T8 1350kv, which is a little shorter than the 1520
And it fit perfectly, all tucked down in there nice and snug like. haha
