AWD Upgrade: One way bearings
 
Hi! Im just a zipzipse'er at this time (Hey Charlie!). The xmods look pretty cool (can't believe Im saing that about a radio shack r/c).

Just a idea from my previous reincarnation racing the Predator Sedan way back then before the rc10tc3..

You guys with the awd upgrade might check to see if there is any company (Boca Bearings still around??) that makes one way bearing in the size the xmod takes.

If you get two, and install them on the fronts differential outputs (or was it the rear to front drive shaft?) Ugh! Been too long. it will allow the front end to "freewheel" under deacceleration, and awd when accelerating.

Thus you get the "punch" on acceleration, but dont loose as much speed when letting off the throttle (example into corner).

If it helps, think of it creating sorta a "diff" between the front and rear awd. In short it helps reduce "scrubbing" and allow more "fluid" control on drifting.

Also will slightly help regain some runtime, reduce motor heat, and possibly help slightly with tire wear.

(I did check to see if anyone posted this tip yet, didn't see anything relevant, so if this has been covered-sorry)

Hehe, Tenth Tech Pretator...

It's not as easy as replacing a couple bearings. You'd have to find a place to put them. I guess you could gut the front diff and install a one way in there, but the with the ball diff upfront (slips a lot) you get most of one way effect, without completely losing front wheel braking.

Don't one way bearings only spin one way? Not sure but if its true then wouldn't you loose your revese?

You'd get only 2wd in reverse. But you don't race in reverse, so who cares? :D

My old Yokomo SE had this kind of setup, as did my friend's Kyosho Fantom. It worked well, but I can't really see an easy way to make it work with the XMods.

Personally, I don't mind it the way it is, because with a gear diff up front, braking helps load the front wheels, and makes the car turn easier.

Oh yeah, now I remember what a one way bearing is! It basicly only grips when going one way and is like a regular bearing the other. I was thinking it can only move one way so if you try turing it backwards it wouldn't budge. Yeah I have one way bearings in my 1:10th scale nitro (It doesn't have reverse anyways). I think they do help it roll more but for these since they dont have real brakes, your breaking distances "might" increase slighty. Well don't take my word on it, I'm just a 13 year old kid:rolleyes: . And thanks neurokinetik for reminding me:) .
