Hyper 7 Conversion
 

I received a package from Mike today. He did a fantastic job on the motor mount. Now I can finally start working on my conversion in earnest :)

I still need to construct some shelves / trays to mount the batteries, speed control, BEC and receiver. Then wait for spring :D

That motor mount looks great! I assume you'll probably do 2S lipo on each side of the chassis for balance?

Planning on using 5S2P A123 pack. Four cells on the right (servo) side and six on the left. They don't have the energy density of lipos but the fast charge and high discharge capabilities negate this to some degree.

Hey, that motor mount looks very familiar (mIke made the mount for my Hyper 8)! :)

If you plan to fill the chassis with batteries, make sure you leave room for the receiver, UBEC, and ESC. There is not much room in front height-wise because of how low the shell fits. Even with a conservative layout, I had to raise the body mounts because of this...

Looks very sweet man! Is that a 1512?

Bye:018:

I think Mike sent me photos of yours when I was originally inquiring about having a mount machined. Good to know regarding the body, I'll have to do some experimentation after the battery mounting system is in place.


Yep, 1512 2.5d.

Your buggy looks very nice. Mike is actually making a motor mount for my 1/8 buggy right now. I hope it turns out as good as yours. :027:

I haven't seen anything Mike has done that did not turn out nice. I wouldn't worry about it to be honest.

that is a very nice mount

that looks nice. should be easy to balance the buggy with the motor in the middle like that.

It should be pretty close. The servo weighs around 2 oz, the speed control is 2.5 oz and the receiver is half an ounce. The A123 cells weigh 70g/cell or about 2.5 oz each. As long as I can find a simple way to mount all the electronic gear on the right side of the car the side to side weight balance should be almost 50/50.

cool, i hope to do that soon. nice mount.:004:
wich esc are you gonna use?
thanks, mike.

I'm going to try my luck with a Mamba Max for now. Hopefully the Neu/MM cogging problem isn't too severe. Racing season doesn't start for a month or two so I have my fingers crossed that Castle Creations releases the firmware update to fix the issue before then, or just release the Monster Max :)

Pretty sweet.

Do you know if a Feigao XL motor will fit with that mount?

And how would I go about getting one of these as well for my hyper 7 project :)

hi, welcome to the forum.
this mount is made by mike, site owner.
e-mail him about it.
and yes, a xl will fit.
as long as the mounting holes or 25mm apart, any motor will fit.

Yes, it should. The Neu motor screw layout is slightly wider than the XL series and you can see in the pic of the mount that the Neu has to sit somewhat cockeyed for the screw holes to line up with the mount slots. An XL should fit perfectly. I actually used a dremel tool to widen the slots a hair so the motor doesn't have to be cockeyed and can sit lower to the spur, which allows me to use smaller pinions.

how is your gearing?

Thanks for the welcome. I've been a lurker for awhile. Some have probably seen my video work with sleebus.jones on youtube.

As for the XL, I was more worried about the length of the motor can. From looks at the pics, that rear support rod looks like it may be a little too close for comfort when a longer can motor is dropped in there.

an XL is 14mm longer then the 1512.

I understand your concern about the length of the XL can. However, you have to remember that the Neu is substantially larger in diameter, so it will get close to the rear brace even though it is shorter in length.

I have my 10XL out of the Revo right now, so I could make a quick test fit if that would help you out. It'll have to wait until tonight when I get home though...

Another thing you should pay attention to is the XL motors shaft is not quite as long as the Neu motor shafts. These guys have their pinion gears set on the shaft with the set screw out, you my not have enough room to get a set screw on the shaft in that orientation. You might want to have Mike mill a slot down in the face of the motor mount to allow access to tightening and losening the pinion set screw if you have to turn it around.

I ran into this once when making a motor mount once. It worked fime with the longer Neu shaft and the pinion set screw at the very end of the motor shaft, but the XL shaft was just a little to short to work without turning the pinion around, and then I couldnt get to the set sew cuz it was inside the clearance slot in the aluminum motor mount.

Not sure if it will be a problem, but just something to be aware of is all.

I would most appreciate it. thanks :)

Nice setup, Gives me something to work toward, along with Briang's design.

I've got my Hyper7 stripped down to the chassis right now, I'm talking to mike about getting one of these mounts fabbed up.

Great work, can't wait to see it all come together.

I think a Feigao XL motor should fit but I'm not certain of the screw spacing on the Feigao motors, someone else probably has a better idea about this than I. Email Mike and let him know what you're looking for. I think he has also made a more traditional mount that places the motor off to the side of the center diff.

EDIT: I should have refreshed before posting :)

Does the body fit ok with that motor mount or will it need to be raised?

My Kyosho has a motor mount like that and it has TONS of room under the body... the motor is nowhere near hitting the body on mine...

Yup, what GD said: plenty of room...

Mainly, it gets tight on the sides and the front where the shell is the thinnest...

More progress:

I made some shelves for the batteries today and did a rough layout for the electronics. I still need to finish my battery packs, add balancing wires and shrink wrap them so they can be velcroed to the shelves. It's a hefty beast, weighing in at 8lbs. 12oz. Unfortunately I'll have to wait for the snow to melt before I can really test it out.

Most importantly, the body still fits :)

It's alive :D

I tested it briefly on the patch of dry pavement in front of the house, sadly there's not enough room to let it hit full speed.

Jake your buggy looks AWSOME :004: :004: . Is that a rc- monster center diff mount ?.

Yes it is, Mike does awesome work!

That thing looks so amazingly nice :004: :004: . The motor mount looks pretty familiar. i think I have seen a couple people now with that same mount. :005:

Very nice job! Looks great.

Lots of battery wire and power poles.:p

The mount works great with little (if any) flex. It works, so why re-invent the wheel? :)

How is the Sport BEC treating you?

Nice buggy conversion! Are you running a 5s2p setup with the A123 cells?

Balancing connectors, I may try to clean them up a little but there may not be much I can do there.

Yes, it's a 5S2P A123 pack. So far so good with the SportBEC, it doesn't have a definitive contour so I stuck a piece of velcro on the flattest side and affixed it to the shelf I hung off the center diff mount. Time will tell if a more secure mounting method is required. I don't have any experience with other BEC devices so this may not be anything special but the SportBEC acts as a pass through so no modification to the Mamba Max receiver connector is required.

Here's a current/voltage graph of a few speed passes I did today. I should pick up an RPM sensor so I can get an idea of speeds I'm hitting.

You're not even beginning to work those batteries :). I'll bet you are getting some pretty good runtime!

I was just fooling around outside today in between heats at the carpet track. Won't have a real track to race on for a couple months. The graph above was on dusty asphalt with Pro-Line Road Rages.
