yeah the stock top plate has to be opened up a bit to fit over the 40t spur. its good though that slotting the mount at least worked. it should be strong still with as wide as the base is of that mount.

pics damnit! lol

[Ryu James]

you want pics? i got pics. tonight i was able to get some more work done and FINALLY got the motor mounted. so here are some pics of the process and then also some pics of all the brake parts for any opinions y'all might have about how best to run the brake lines.

first, used a sharpie to mark up my drill holes.





here are the motor mount plates mounted to the chassis. using plates allows you to remove and replace the motor without losing your gear mesh




so here is the motor mounted up. as you can see it is a close fit, but then again who doesnt like a tight fit? right now i have 15/40 on but the 12t pinion fits also.






here is the mounted plates from the bottom of the chassis. i didnt have any 5mm button head screws, which is what is supposed to be used to screw the mount to the plates, so i just used some 5mm flathead for the sake of getting some pics. as you can see its just like a tekno motor mount setup. unfortunately i put the forward slot a bit too close to the forward screw but it still works fine.




here is a 60mm fan i got for the motor but may just use a 40mm fan since it will sit right inside the square hole on top and provide enough cooling.




and as you can see despite the tight fit everything still turns freely.woohoo!

ok so here are some pics of the brakes although i havent started on them yet.

here is one caliper i mounted just to see how it would work. they work amazingly to be honest. its gonna stop on a dime with 4 of these. you can see where i just drilled through the hub to mount the calipers just as Kaz had explained.



here is how i plan to run the cable and tubing. for both the front and back this should work to run the cable through the shock tower.



then this little part will need to be mounted on the front and rear top plates respectively to hold the cables in place and direct the cable toward the brake servo.





anyway, that is my plan but the only issue i may have is how to securely mount the cables to the servo arm, or to a rod which then connects to the servo arm. i plan to use a full servo arm and have the front brakes connect to one side and the rears to the other so that all 4 brakes are applied when the servo is actuated. here is a pic of all the parts in the integy disc brake set. perhaps someone can explain how all the parts are used when put on the baja. actually, thats not all the parts. the long connecting rod isnt in pic. that is my main question really. how is the cable attached to the connecting rod? in a special issue of "Radio Control Car Action" called "Desert and Off Road" there is a feature on a custom baja and it has the integy brakes with some "minor mods" made to it. it looks real nice but there is only one pic really where you can slightly see the setup. i am trying to see exactly how the system was ran.

[Ryu James]

ok so i figured out the brakes. the pics are self explanatory. i just kinda jerry rigged everything to demonstrate how the brakes could be setup. i plan to do a few mods to the system but overall the is the idea.

[KaztheMinotaur]

I see. So the little piece that the cable ends attach to isn't mounted on anything? It just floats on the rod?

Just been eyeballing your brake setup, very interesting. I would have used 2 servos, one for the front brakes and 1 for the rear. I would mix them using the dedicated brake mix on my m11 radio. It has a specail setup 4th channel that is slaved to the 2nd channel, that way i could adjust brake balance front to rear on the fly via the radio. Just a thought.

I do like those cable brakes, looks very solid, and should stop the beast well.

that is a good idea. i have thought about getting the m11 or 4pk radio so that i could have 4 channels but i think i will just stick with my spektrum for now. and these brakes do have amazing stopping power. they should work well. i will try and get a video up soon.

yea ryu's is definatly getting the "class award" but i want to see it done damn it! lol

[Ryu James]

so here are a couple teaser pics. not finished by far yet but i got this 5t body to fit and got it painted (spoiler not mounted yet). i ordered the Todd LeDuc wrap from UpgradeRC and a set of 5t rims with dunereaper tires but i am looking at the MXT tires from hostile and may just sell the dunereapers. tomorrow i meet with my mahcinist to draw up the custom hubs that will be used for mounting the 4 wheel disc brakes.
i am gonna try to get a video this weekend of it running, but without brakes. probably just go to a wide open area so i wont need any brakes. this will be good to actually be able to test temps also.

Oooh.. she looks sharp..! Finally some more pictures... Hurry up man..!!!!

[_paralyzed_]

looking sexy. I like it black like it is, w/o the wrap. Looks fast.

oooo pretty!

thanks guys. i was up til 5am last night getting my shop all cleaned and organized so it is ready for me to just tuck my head down and just work my tail off. its so much easier to work in a clean environment. and i needed a good kick in the ass anyway. its a good thing i have the support of the RCM forum members. its better than AA!
