But yes, I really really want a CD. I had been working on a mount end of last year, but its a pain and expensive to do. Got halfway thru it. I wanted it to mount in at least one set of tranny holes and have motor forward. Later decided just to mount on a skid plate like a traditional diff.
Lately I saw the (G?) maxx CD mount that mike made. I would really like something like that w. his slipdiff. I've got time to put this together, so I'll wait on those. the tekno mount is a simple mount for now and to see how it performs. If need be I'll step upto the 80mm 1100kv if needed.

What is the amp draw on that thing btw?


That is one sweet mount. But I prefer the motor to be at the center. Anyway, I believe that number of people might be interested in the mount and maybe you can start a thread about this mount. And when you have enough people, I bet the price must be much lower. You can ask Mike to machine this.

Oh thanks, its still in pretty rough stages still. I made a number of diff designs, but only the one was much advanced.
CAD is freaking hard lol. After playing with it I can really see just how great Mike's work is.

IDK if I would actually had emachine do the work, I was just using the proggy to play w/ over the Xmas break. It works well for simple things, but I was having a hard time doing others, like putting bolt holes on the side. The only way to do it economically would be have a large # of pieces made. 1 or 10 is not much of a price diff.

I would def want to prototype something 1st, I highly doubt it would be right on the 1st try, and I don't want to make some POS like the Kershaw DD kit.
I had thought of giving up on it as the Kershaw kit was supposed to come out soon and the Flux just got announced when I was doing it. I figured it would be a mostly moot point then, but seeing the weaknesses in both the designs, there is def some room in there for a good mount.

I did angle the motor on purpose as the width between the chassis is fairly narrow (74mm) and there is not enough room to fit a motor like a Neu and the spur gear if they lay flat, plus it puts the driveshaft at a hard angle and the spur have would to end up sticking out the side. I calced an angle that would lay the most flat and off to one side, but be flexible enough for a variety of gearing options. What its rly designed to do is have the motor going fwd, leaving back open for batts, and space on the side for the str servo. God knows just how it all would end up fitting together w/o some prototyping 1st. Unless you've got access to cheap machining, its an expensive process

Yeah it is too narrow to fit the motor if the mount lay flat on the side of CD. Plus, the drive shaft will have to be positioned at a certain angle which will cause inefficiency and stress to the drive train. What I meant by motor at the center was the motor is positioned right on top of the center diff.

Really hope that Mike can start working on that CD mount for the emaxx. With this mount, the CD can be easily fitted on the Savage. But even then, my guess the mount would still cost around $60-$70.
