i tried many times to drill my strr 10t pinions, and barely dented them. you won't ever touch it unless you are a talented machinist from what i can tell.

I'm not even in the same solar system as a "talented machinist.". I gave up and used set screws on the flats.
 
Can someone confirm the diff shim size needed is 13mm x 16mm?

What I have is installed or I'd measure one.

EDIT: found it in the manual and 13x16 is correct

Couple questions - Do the Ofna CVA's change the track width? And is there much if any benefit to running them in the back axle if it's non-steering?

Also are the RC4WD alum knuckles worth upgrading to?

IMO..........

The OFNA CVD's are great for front steer and give you a HUGE
advantage in steering when mixed with the RC4WD Knuckles
The gain in "THROW" of the RC4WD knuckles is greater thus
giving you more steering (APROX 20%) But would bind with just dog bones.

If , however you are going "Non steer" in the rear (IMO) there
would be no bennifet ;-)

As far as track width:
"Track Width" is measured using Center of tire contact patch to center of tire contact patch..
Track can be affected by wheel backset..as well as shimming the wheel Hub but not
by the OFNA CVD's unless you are cutting them and modding them for shorter length axles


Regards Rick

another thing with dogbones is there inherently more slop in the driveline. but that really isnt an issue unless you decide it is on...:thumbs
i have the rc4wd knuckles and love em. they are also BEEF. i use an ofna Universal drivshaft in mine.


new topic:

i am just using some Tamiya Grease on my gears. not a lot either, just enough to keep things smooth. http://www.toysonics.com/tamiya-87022-molybdenum-grease-10-g.html

its awesome sticky stuff too. another options is the anti wear grease. its about as thick as epoxy, is lasts forever.

While building my last truck I did some searching here and saw recommendations for Mobil 1 synthetic grease (for car brakes / bearings / etc), so I've started using that since we had some in the garage. Haven't really run the truck yet but it looks like it'll stick to the gears pretty well.
 
I don't want to sound like an idiot. I can't seem to find ofna Titan 40274 shafts. I need four I lengthened my mad force. I would like the most beefy and most available cva.
 
Are those in stock? I couldn't find much in stock a few months ago.

I did find the HPI setup in stock at wapak hobby shop back then

86567 122mm bone (long side)
86566 86mm bone (short side)
86504 8mm axle pr.
87235 CV rebuild kit pr. (assembly hardware)
 
Got Titan shafts yesterday. Man are the nice. Hate to cover them up. Had to drill the pin hole put for the kyosho pin, bit that wasn't a problem. Now that my axles are beafed up. I need to bead up the old 3906 emaxx trans. Onto search for more info.
