**Who figured out the plastic center diff spur? -** 05.20.2009, 01:30 AM

Just curious what anyone came to?

I may start on my .5 again, and was curious what anyone did. Since my steel spur is messed up, and I dont want to pay for a new gear (pretty pricey) so that and plastic is nice and quiet

I dont mind modding the chassis a little bit. But LMK

I took a 46t kyosho plastic spur, and had the machinist open up the center hole so that it fit around the diff cup. Then I took the steel spur to the grinder and removed the teeth and a little more. So basically I made a backing plate out of the steel spur. It is hardened so drilling it was not an option. I made 4 slots with a fiber cutting disk, and then drilled 4 holes in the plastic spur. Bolted the spur to the backing plate with nuts and bolts, plastic spur on the diff cup side. Last I made some 1/4" or so plastic spacers to put under the diff bulks to raise the diff enough so that I did not have to enlarge the hole in the chassis.

I bought Linc's CRT .5 and the plastic spur works brilliantly! I haven't been able to run it much because one of the turnbuckles sheared but it works very well. I think I've got a picture of the spare spur gear I got with it.

EDIT: Pics:

Yup thats it. Unusullied, you should start taking pictures of Bigfoot or the Loch Ness Monster... That way we can get a slightly better look at them

Nobody has been willing to pay my price for those pics
