Mechanical Brakes

that looks like a good idea, id like one as well if he makes some ,lmk , if not i could use some aluminum and make a spacer to allow me to gear back to a 16 tooth pinion or smaller , which gives me better motor temps


thanks

heres one more pic to show the clearence



ill have to get a measurement on the thickness of the adapter, to clear the brake pad bolts, and then use a long shaft pinion

I got a response from Mike today. He said he would try and make a couple of the spacers I posted sometime this week. It should be pretty easy for him to do with just a couple tweeks to his program for the front motor cover.

I'll post up some pictures when I get it and install it.

sounds great, if it would fit the motor i have id take one as well, but i dont plan on running this motor forever, just need some $$$$$$$$

[jhautz]

It should fit any motor that has a standard bolt pattern. If its the 9xl you are running it will fit.

Just send Mike a note and tell him you want one of the motor spacers he is making for Jeff. I'm sure its no sweat to make another one once he is set up and machining them.

ok i just sent mike an email....

i mocked up to check .... and it should work sweet, i used spacers i had and i think its about 4mm thick so that is right, and i will have to dremal a very little on the outside brake pad (1mm) and will also trim a small amount off the heatsink/motor clamp to ensure the brake disk wont hit .. heres some pics from my mockup, oh and i have plenty of shaft for pinion mounting, i used a 15 tooth in mockup but i should be able to use less as well

Could Mike possibly add the 4mm to the front of the heatsink/motor clamp during machining? That would take care of two problems at the same time, and you could free up a mm or so by combining the two. That would maximize the motor shaft available length. Just a thought...

[jhautz]

Yea linc. That would work for sure, but I dont think Mike makes those motor heat sinks in house any more and changing a big part like that is sure to be alot harder to do than just making the simple adapter plate, but its definitly worth asking him about if you want it.

I personally am not planning to use a motor that requires an clamp/heatsink so it woulnt work for me.

Entjoles, The plate I asked him to make for me was thicker than 4mm. I think I will need 6.35mm (1/4") to clear the whole brake mechanism. Thats what I asked him to make for me.

ok thanks, ill shot him another email

i also trimmed off part of the hs/clamp and got lots of room

it will accept a 14 that i have and maybe a 13 if i dremal the brake pad plate

so i could just use a neu adapter plate with part of it cut off right?

this is the size i will need when i get a diff. motor w/o the heatsink clamp

my 4mm + the hs.clamp of 2mm = pretty close to what you came up with

i wish i had a caliper

Xray is releasing a new buggy in a few weeks and there are lots of folks dumping the ECs and TQs for good prices so they can get the new one. I think they are awesome buggies, infinaltly adjustable and tough as nails.

I know a little off topic for the post, but I have an XB8EC (with e-brake) and think it's an awesome buggy.

There's a good looking XB8EC roller deal here on e-bay right now:

I used a spacer for a while, but it was a hassle to line up the spacer, motor and mounting holes. I glued the spacer to the motor to hold it but the glue never held for long. If you can get Mike to add a few milimeters to his mounts or the heatsink that would be prefect. Another idea I had was making a spacer, and using the unused holes on the motor you could bolt it to the motor. If you countersink the holes and use short screws you should be able to use the extra holes on the motor can to secure the spacer to the motor, basically making it one piece. I will dig out my old spacer and try it out.

i picture a custom built ( by mike) center dif plate that has the ESC in the rear near the motor and a mini servo in the front with a bell crank for the rear brake.

so how much and when can i pick it up? :-) ( im serious)

ok heres what i have been up to, i got the neu spacer and modded it to clear the rear disk, i also did some dremeling on the rear brake pads, geared 13/48 for now as i am planning on trying my 9l in it(thoughts on this motor??2700kv,4s in a truggy)





got this in the mail today from mike, great idea jeff, and great work mike, i will use this one when i get a neu motor



**shark , your mount is cool, same basic idea, as for using these spacers, it works great and there are extra holes in mikes mount to secure it to the motor and then use 2 screws in the diff mount so it works great

thanks for the ideas guys , im sure this will be a great improvement over motor brakes, now i just need a mmm, and a neu 4s battery

Looks good. I got my brake spacer from Mike on Thursday. I installed it over the weekend, but havent had a chance to post the pictures up. I'll do it tonight. It works just as planned.
