Been looking for the answer to this question for a long time. A straight forward, simple answer. I'll put out my findings:

Grid RC - Motor Mount for RC8be.
Yay! Great upgrade. What size pinion?

Answer: Mod 1 5mm any tooth (depending your set up) should, SHOULD work.

Here's my choice (19t). http://www3.towerhobbies.com/cgi-bin...0&I=LXXKB4&P=K

OH, and it has to be short shank. At least if your buying the inner mount from what I know.

Yep, HB (HPI) works a treat.

If you're interested, I have a nice B4 with tons of spares, Futaba servo, 3 batts, MMP w/5700kV that I'd sell for a good price to you Gregg.

I don't know why you were searching a long time. It's been posted many times here and it's on Grid's web site. As you found you need a Mod1 pinion. Grid recommends (and I've used) Hot Bodies pinions (as you correctly stated, they must be short shank) If you use the external support, you have fewer pinion choices (max size is something like 19T, but don't quote me on that).

Sorry Jason, I took pics like an hour ago, and then dozed off. Didn't even realize I fell asleep. Posting now.







And Billy, I don't know much about either buggy. Do you have pics? And what's the difference between the B4 and the B4.1?

Looks good Gregg. Mine should be here by Tuesday. I need to make sure that I have enough connectors. Still thinking about ordering the 206B this weekend.

I'm thinking about taking a day off from work to do some practicing at a track close to me after I get the batts.

i got mine today i got a little start on it, but then had to go out to eat with the wife.. ..

tomorrow i'll build some more...

Its all good. Thanks! I left my batt leads a little longer knowing I can always shorten them later but other than that I have mine the same way.....except for the vastly superior RX8 mines connected too!!

Vastly superior... Lmao!

I can't wait for my grid mount. And I need some more hopup parts. Thinking about the alum hubs and chassis braces. Maybe the Integy alum gear boxes.

I would like to add all that stuff too. More importantly though I would like to add money to my bank acct first!

The aluminum hub carriers are totally worth it, IMO.

Do you guys use any shims in the upper front A-arms?

Also thinking about using shims on the rear carriers to take out some excess play.

pics of my lid, looks great, david did a good job!

Integy has some really nice forged ones. They are a brand new release item. And they are cheeeap! $22. Rears are the same way, and same price. And Billy, I haven't shimmed the front, but you're right, it's pretty sloppy up there. Rears aren't much better.

And Greg, that's a nice looking Lid.

You know, the only good thing I've heard about Integy is their setup station. I havent heard anything good about their hop up parts. I'll let you guys try out their RC8Be parts first.

Do you guys have any play in the steering knuckles?

Well, they have their standard aluminum cheapy stuff. But these new hubs are forged. I'll look at them in person before I take the plunge. Either way, its only $22

And yeah my fronts are a little sloppy.

Edit: these are the ones Billy.
