brushless 1/5 4wd conversion about to begin! couple questions.

[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.

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

i think in the baja that part sits on something but not sure. when the system is setup and everything pulled tight i dont think it will sag much at all. but thats what i want to do is come up with some way to link the cable and rods without that heavy little piece. the setup on that baja in the issues of RCCA i mentioned is really clean. youll have to check it out.

[KaztheMinotaur]

Yeah I think it would be better to mount it on something.

Do the cables interfere with the motor mount or anything?

[KaztheMinotaur]

Did you have to grind the corner of the bracket where the cable mounts or the hub to get full steering throw?
