Center motor mount for hyper 8.5?
 

Does anyone know where I can get a motor mount for a hyper 8.5 that places the motor above the spur? I've tried contacting Mike, but I think his spam blocker is getting my emails, I hear he's usually pretty quick to respond.

Thanks.

I know BrianG has a motor mount like this in his Hyper. What Hyper model he has exactly, I can't remember. But have you tried all of Mike's email address's? He has quite a few actually...

I tried mike@rc-monster.com. I'm looking for one exactly like BrianG's actually. He got it from Mike.

I asked too about this maybe a week ago but Mike is very busy... Brushlessboy16 is mocking up a mount atm in autocad...

i also asked him a while back. id still be intersted. i got the hyper 8 mount, which works if you get the hyper 8 diff post thingys - in my thread.

I know it ain't fancy machine work or anything but I made one for my MBX...

Just bought 1/4" thick Al and bent it at a 90, drilled and dremeled the rest. Works great but like I said, not fancy. :mdr:

like this one i made?

Great cad work! I am patiently waiting on one from Mike for my Maxx converison

thanks magman :D

If it were me, I'd leave just a little bit more material to add strength. But nice CAD work though!

New version is being worked on ;)

indeed..

i too am working on a central above spur mount , shouldnt be too far away either

I just made one on my CNC exactly same like on Cad drawings. I will make pictures. I made it for new Hyper 8.5pro project

I have 2 people I know with CNC machines. They both need to see plans before they tell me if they can do it or not.

Anyone feel like sharing their plans?

Also what type of aluminum are you guys using?

Contact B16's - his is looking great - Just need someone with capliers to take final measurements...

I have calipers :)

could i get measurements of the center-to-center distance of the center diff mount holes (where it attaches to the chassis)

also the distancece between the inside of the front and rear center diff mounts

Here some pics of mine motor mount

How does the top plate attach to the motor mount? - Any clearance issues with the rear brace?

I'll get that for you tonight with pictures so you can see if it's correct.

looks like it's all one piece.

Can't be otherwise you would have to machine LOTS and LOTS of metal away to get that shape!

I see what you are saying..

Top plate like a brace what is fixed behind with screw on motor side. I will redesign for simplier faster fix. With 12t pinion and hyper 8 default spur Medusa 60mm motor allmost tuch rear torque bar. Maximum gears are 18/52. XL motors (74mm) will not fit with low gears.

Hyper 8 have stupid diff mount what makes diff/motormount difficult to mill. I have only 3 axis machine so i need to do additional details (shims) or trimm it by hand to fit it.

silly question. but would there be any way to mount it the other way? like to get it out of the way of the rear chassis brace? looks good though! keep up the thinking guys!

hmm elaborate on that, i dont follow?

dont worry. im an idiot lol.

i thought if there was any way to mount the motor the other end of the diff, but to do that u would have to have a HUGE shaft... OR have a really HUGE pinion to clear the top of the diffmount. (i.e. a spur sized one! haha.)

edit: OR flip the diff round, then it would work maybe? u would ahve to cut out a slot in teh bottom though, not too difficult if you really wanted a longer motor...

On buggy if you flip center diff it will not fit under body. Two - three solutions to fit bigger motor, redesign rear torque bar or use bigger spur gear, place some spacers under diff or make new whole diff mount what is taller.
I designed mount for 60mm medusa motor its more than enough on buggy, no reason to use any bigger motor on that.
I will put 74mm motor to get gearing limits...

or just clock the motor to one side by 10 degrees or so

Will the motor mount in Mikes store fit a 8.5? I know it's to the side, but it seems like the only quick way to make this happen.

see my thread in the buggy forum. :) (it does with some parts from the h8 diff)

Okay, this is my first time using calipers, not sure if it's right...

for the mount holes I have 34.70 front to back, 21.15 side to side, 40.74 criss cross.

hmmm 34.7? and 21.25. were your calipers zeroed? kind of odd

Should they all be like 35.5 and 21.25, or should they all be whole number?

i would expect a hole number or half, quarter etc.. just not .4 :D

Easier to measure the outside and inside of the holes and then split the difference rather than guessing the middle... :)

chris you have a hyperst, you can measure it ;)

What parts should I order?

I don't have calipers - sorry
