How are those ofna gaskets for the center diff working? Any problems?

hunter306 · 02.22.2007, 05:51 PM

I'm working on a Hyper 7 - yes, one rev. behind conversion right now... Does anyone know if that motor mount that is used in the Hyper 8 conversion in this thread would fit the Hyper 7?? The designs look VERY similar.

I like the center mounted motor, gives the car a much more balanced look, and I'm sure "feel" on the track.

Also, if I can just use your expertise. I've got a Quark125b controller, and a Lehner 1940/7 Hi-Amp motor that I'm planning on running... will that fit be ok? Or is that under-powered?

@lydiasdad: The gaskets seem to be working well for now, but I really haven't run it all that much. I'll probably end up getting a Kyosho center diff and the Kyosho spur as a spare in case I run into any problems with leaking.

@hunter306: Actually, I was originally looking at getting the 1940/8 but they were out of stock, so I got the 1512 Neu instead. From what I understand, they are comparable power-wise, and the Neu has PLENTY of power. The 125B may be a tad difficult to squeeze in there. I had trouble getting it to fit while allowing proper wire routing and clearance on the shell.

Since the Hyper 7 and Hyper 8 diffs are interchangeable, I would think the mount would work.

The center-mounted motor does look/feel balanced, but a layout with the motor on one side and the batteries on the other frees the area over the CD for all the electronics.

Hey Brian, Thanks for the help.
Couple more questions!

Where did you get your hands on that Center Motor Mount assembly?
--What online store or place sells that part?

Do you still have those 2 unfinished lipo trays? What are the dimensions?
--If you do, I'd like to take them off your hands, let me know where to paypal the shipping money!

Also, I see what you are saying with the Quark125b... it is huge, I've got one in my Electric LST2 and it was a pain to fit, but I think it'll work. These cars have some decent sized trays on them!

I had the motor mount/center diff mount custom machined by Mike. Drop him an email for more info. It is quite solid. He even re-centered the mount for me (stock is set up so it's slightly off-center).

Yeah, there was room on the trays, but I didn't want anything mounted on the plastic for strength. Everything on the buggy is mounted to the metal chassis.

One last question, I edited into my last post...

Do you still have those unfinished battery trays? What are the dimensions, can I pick them up from you?

I made the one for my LST2, but I don't want to go through that hassle again if you've got a couple you're offering!

Oh...wow...I actually read this page (and most of the one before it). I can't beleive I missed this. :007::007: :032:

Does it bolt right on, or do you have to drill holes? Also, did you need custom dogbones or did the stock ones work?

Excuse my laziness for not wanting to read all 6 pages of your thread, but who made that centerdiff/motor mount? It looks awesome (as does your entire buggy).

MetalMan · 02.28.2007, 11:21 PM

I do believe the center diff/motor mount was made by Mike :).

squeeforever · 02.28.2007, 11:46 PM

Yea, look 4 post above yours. :p

BrianG · 03.01.2007, 12:12 AM

Yes, made by Mike. Did a very good job too! Sturdy and purrdy! :)

BrianG · 03.01.2007, 12:43 AM

It bolted right on - no extra holes. And those are the stock bones. Not only was the CD moved to center, it was raised about 4mm - enough so the spur clears the chassis. And the bones fit better now than they did when the CD was in the stock location!

I'm sure it helped that I sent Mike the whole buggy so he could take whatever measurements he needed.

BrianG,

Can you tell me what gearing (pinion and spur) you are using?

Thanks.

BrianG · 03.05.2007, 10:26 PM

46T spur and 14T pinion for now. It's VERY fast, maybe too fast since I have a 2600 kv motor in there. I'll probably get a 12T pinion so the speed is more controllable for the track...

Excellent work. So when are we going to see a vid of this beast in action.
