So upgrading to the New JRH Crawlmaster brushless motor that he has on pre-order won't be a good idea then.:roll: From what he says some breakage might occur...
So installing it in the prototype chassis will probably tweak it a little :shock: :roll:

Sweett!

I haven't seen a chassis get twaeked yet from motor torque. The couple that I've seen bend were the result of a big fall.

Kool8) . Cause it'll be getting a new motor/esc combo from JRH, So we'll see how it goes"thumbsup"

I would imagine that you would have something else snap before the chassis started to twist up, something in ht etranny or axles or driveline would most likely fail first. unless everything is made of steel!!!

Hey Brad,
can you please tell which is the distance between the lower links mount point on the chassis ?
The reason I ask is that I tryed to design my own tvp chassis but ended up with a 14" weelbase, due to a very long belly.
My front lowers are about 110mm eye to eye and don't think they are longer than 'standard crawler' ones. Due to the triangulation angle I cannot shorten them without changing the mounting point.

Perhaps I scrolled this thread a bit too fast, but I saw a photo of the sw3 chassis with a R2 tranny on it.
The tranny was fixed only with 2 screws on a side. Is it sufficient to take it in place ?
Besides mounting the r2 that way the output shaft has a great offset about the chassis center and it is not aligned with the bevel pinion in the axle. Trying to put the R2 shaft almost in the center causes some weight bias on one side: is it worse than having the shaft disaligned with the pinion ? Of course the sliders and yokes give some freedom but isn't it better to reserve it for articulation ?

Thanks
Filippo

Try shorter links."thumbsup"

The lower link mounting points are 3 1/2" apart.

The R2 tranny is solidly mounted by the 2 screws shown in the pics.

Both the Stampede tranny and the R2 tranny have offset outputs for the driveshafts. Neither tranny is offset enough to bother driveshaft angles. I wouldn't worry about centering the outputs of the tranny in the chassis. As long as your ride height isn't set too high, the driveshafts shouldn't bind while the suspension cycles.

Any updates on when the side plates for the prototype chassis will be available?

The chassis material should be ready for pick-up now. I've got a bunch of skid plates machined already, as well as some link mounts. As soon as the chassis plate blanks show up, I'll sand them and send them out to anodize. Then start machining them.

That truck is awesome. Where did you got those bottom links. I want to get the same ones. I hear that material is great for sliding over rocks. I was wondering about the upper links plates if you can make them black too like the same color as the black chassis. I would relay like both the chassis and the upper links plates.

Brad (Bender) makes his own Delrin links but you can buy them in different lengths from Finishline RC (not sure if Finishline still sells online but I think they can hook you up) Tell them Robb sent ya!;-)
