mp7.5 to brushless, of course

hey guys, here are som updates on the custom work so far.

ill post the link to the album in photobucket so you can see all the pics of the chassis.

i got the mount nice and sanded with some 400g around the edges and it clears the center diff cup now. i got kinda lucky with the measurements for this mount. the base is flush with the bottom of the chassis. this has allowed me to drill fromt he bottom of the chassis into the mount. i can tap the hole and reinforce the mount with a bolt directly to the chassis. i think this will greatly improve the strength of the whole mount.



i also cut the servo tray and rounded that off to make it look nice and neat.



i also have some twinforce battery trays that will work well for my batteries.




and the link to the whole album.

Looking good, you definitely want to attach your mount to the chassis from the bottom (as you mentioned). The thickness of your mount is also good because 5052 aluminum is a little on the soft side, but 1/4 should be fine. Nice solution to those that don't have the equipment to machine the center diff bearing hole to make a one piece motor mount. Question, any reason why you have the motor mounting screw holes offset? Just curious.

Looking good- have you considered getting some shorter screws so that they sit flush to the motor mount?

shark:

i only have the mounting screws drawn offset. once i get a motor i will then be able to decide if it needs to be offset.

BL RVO:

they are just not in all the way. mock up only. they sit flush when tightened all the way.

in the coming weeks i will be able to get a better idea of what type of holes to put in the aluminum to lighten it up and maybe add some cooling fins, but i dont think cooling fins would be much better than just leaving it alone. almost just a gimick to put cooling fins on a motor mount.
