I've got an old RC12L (no LW, L3, or anything else
) that I'm going to be running with Peter & the rest of the crew at Redmond Hobbies on asphalt. My current problem is figuring out how to install my IRS132 (large diff D-ring, fiberglass axle, clamping left side hub, 3-bolt setup, etc.) setup to the rear pod. I'm not sure what order to put the parts on, the spacers, and other parts than what it came with on. I know I need to pick up an un-flanged bearing to go in the center of the spur gear, and obviously the rings go on either side of the hub. I know that I need to put a flanged bearing in either side of the right side (diff side) hub. after that, I get confused...
The Associated RC12L instructions (circa late '80s) are no help. They had me putting thrust bearing assemblies between the pod and left hub as well as the pod and the diff assembly.
I figured out that the RC10L SS "axle spacers" (or something along those lines) replaced them so I picked up a pair of them. I'm not sure if I still need to use them, just use one on the clamping hub side, or what. Also, there's that stepped "spacer" thing that came with the IRS parts. And then I suspect I need something on the outside of the right side hub before I put on the nut to adjust the diff with. Some sort of a cone washer setup? I did pick up an Associated #3435 "Belleville Washer" setup, but it looks like it's supposed to sandwich the wheel and everything over towards the diff, and I *think* that I'm supposed to be able to take the right side tire/wheel off without having to lose diff adjustment. Any suggestions? Maybe an exploded diagram/picture or two? Link to a PDF of assembly instructions for some other 1/12th scale that uses IRS parts on the rear?
Once I get the rear pod done then the other big question is if I should bolt it to a fiberglass or graphite chassis. I've got both in my pile of parts.
I suspect graphite, but the fiberglass would flex more and that might be better for asphalt. Comments? I'll be running it with an "old style" front end (I've got a couple of them).
One last one for now... Suntan lotion vs. Paragon? That Paragon is nasty stuff from what I've read (and smelled). What's the story with Suntan lotion? Any partiular brand? Particular SPF?
Alternately, I've got some Trinity Touring car tire cleaner and traction compound stuff, but it's for rubber tires. I'm guessing I would NOT want to use it on the foams? Any other less nasty foam tire stuff that might be better/easier to deal with than suntan lotion?
Thanks for any suggestions!
