Well, the only thing I see is that I REALLY DON'T LIKE THE ESC BEING UP SO HIGH. Think I'm going to contemplate cutting that top plate from the middle screws back, and chop that receiver box down. Hrmmm...
Edit: After further contemplation, I think what Wiseman 454 did really is ideal. Unfortunately, I don't have much in the way of extras to work with (just getting back started after 20 years), like the crawler servo mounts he used (any idea which one that is?). So I am trying to figure out a way to keep the inside part of the top plate (the part that crosses over to the battery box) intact, along with the inside wall of the receiver box, to keep as much of the rigidity of the original design as possible, and to use what I have.
What I don't like about this idea is that it brings the RX8's posts pretty close to the new inside edge of that aluminum plate when you drop it down. Electrical tape would work, I suppose. Laying the ESC with posts inside leaves about 5mm to the back of the motor. Is that enough? Any thoughts?

Check out the factory team servo mounts for the Associated T/B4.

If you have someone who can cut you some carbon fiber, assuming you don't want to modify the stock top plate at first, you can make the plate over the servo mount pretty easy.
The stock servo mount pieces are actually pretty beefy, and from what I understand on the ofna forum about the mounting of the speedpassion ESC, you could have uses the stock mount positions for the servo assuming that you used a smaller ESC like an RX8 or MMM.
I'll will be giving this a look and see what I have to rig it up that way. But I would say compared to how high the ESC was on conversions that hung it over the rear center driveshaft, this is still lower.
here are some pics of what wiseman has now as the speedpassion ESC popped:

You will find it's difficult to use high kv motor on hyper 9. Because with 40t spur gear and T8 motor, you can not use small pinion. So is there any bigger spur gear can be use on the center diff??

With a motor the diameter of the T8, 13T will be the smallest pinion you can run - maybe a 12T if you do some grinding on the can. A 36mm motor will give a few more pinion options. I'm not sure how the front/rear diffs are geared on the H9/9E but truggy diff gearing (10/43 or 10/44) would definitely be a good thing.

No, anything larger than a 40T spur will come below the bottom of the chassis. Unlike other designs, the center diff can't be shimmed up.

Hmm, not sure I understand why you can't get smaller than that. I'm guessing the diff outdrive cup at the front of the center diff against the motor can would be where the clearance runs out first. The cup should be 13m od, same as a 13T pinion. The Tekin can and the 40T spur should be the same diameter. With a little relief on the can, and maybe on the diff cup, I'd have thought you could sneak a 13T in there without much problem.

For a 36mm motor, it's ok. But if you want to use T8 like me, you will find it's difficult....
