Pitbull assembly

[LUW]

Hey guys! :)
I haven't been much active around here lately, mostly because of frustration. I'm still without a servo, so no half 8 fun for me. I ordered a stock replacement, but it's only going to arrive in 30 days :mad:. I think I'll try to import one; it'll be more expensive but won't take forever to arrive.

Well, so to keep in touch with the hobby, I begun assembly of the PitBull chassis. Besides Kyosho's oil shox and bearings for the wheels, everything is stock. So far, I've done this:

Things look to be going ok, but I have a few doubts:
1) Can I do without the front and rear torsion bars? If not, I'll have to drill the chassis to screw their base in.
2) The stock chassis has 5 screws to assemble the central diff to the chassis. The 5th screw is under that little "tower" to the left of the gear housing, on the bottom pic (there's a screw on top of it). Can I leave the central diff assembled with only 4 screws?
3) How will I assemble the stock servo and braces? On the stock chassis there are 4 holes to the right of the front shaft where the servo braces are screwed in. Do I have to drill the chassis?

For now I'm not sure about the above. Very probably I'll get stuck in other parts, but I'll post my doubts when I get there.
PS: Anyone know where I can find a new stock servo for sale?

I Have a brand new one never used ill send ya
just pay for the shipping and its yours :)

let me know where you live so i know how much itll cost :D

[leapingbug]

O and for your other questions
You dont need to torsion bars on the pitbull
you only nedd 4 screws to hold on the center diff (they are the ones that together make a perfect square under the chassis)
The servo you could mount with servo tape Parma makes some. But it will pop off every now and again so if you want to mount the servo a litlle more securely youll hafta drill (just make shure you use a counter sunk bit) :D

or use shoe goo to hold it.

Thanks man! :) I'm from Brazil, so by airmail I guess it will be around what, 10 bucks? And you sure you don't want to sell it? I'll pay market prices, no problem at all. I'M DESPERATE!!!! :D
And thanks for the other info too!

I would rather use a permanent solution, like drilling the chassis, but unfortunately I don't have a drill press. I'm not sure I could do a decent job using an eletric hand drill. So I guess I'll have to glue the thing down. Is shoe goo better then servo tape that leapinbug suggests?

[BiGRoB21]

shoe goo will hold the servo down better and when it is needed to be broken loose will still come up fairly easy

[LUW]

Shoo goo it is then, since I don't have the drill press. Thanks Rob! :)

no problem, just remiember you dont need much. just a small blob on the bottom of the servo, then press down and let dry over night.

[LUW]

Is the precise positioning of the servo critical? I mean, in the stock chassis, you will place it exactly where it has to go, but I'm afraid that while gluing it I may end up putting it in a non-optimal position.

And would it be interesting to mount the servo to the stock servo mounts? I think that maybe they could aid "stabilizing" the servo in position.

[BiGRoB21]

just make shure the link is stright so it will not pop off when at full throw. also make shure the ball cup dose not hit the center drive shaft. its not hard get it right.

Well send me 10 plus market value for the servo and your shipping adress and ill send it out to you as soon as tommorow My paypal acount is
Takaad101@hotmail.com :D
If you need an extra stock esc/rx i have one let me know

[over_powered_rookie]

if i knew how to load pictures id show you how i have mine done with a Hitec HS-81MG servo...no drilling required and yet its bolted in place with the holes provided in the chassis

No problem. But I still have to find one online for sale. Do you know where I could find the servo? Thanks for the offer, but my RX and esc are ok. Besides, if I ever have trouble with one of these three again I'll definitively go aftermarket.

over_powered_rookie, you bolted it in but didn't need to drill the chassis? :confused: If you don't have anywhere to host your pics online, send them to me (mini@werner.med.br) and I'll upload them for everybody to see.

Almost done!

leapingbug was kind enough to solve my servo problem, and as soon as it arrives I'll try shoe gooing it in place, so I think that's taken care of. But I'm stuck again :(. This time with the stiffy plate. BitHed added a "pre-production" stiffy plate with my chassis (thanks dude! :)), and I want to install it. But how? Will it just go over the central dif and screwed over the rear dif and the steering assembly, kind of like this?

But if it goes there, how can I attach the antenna base? And should I then just shoe goo the esc over the stiffy?

[quikslvr]

I attached my antenna by drilling a hole toward the back of the Stiffy and using an aluminum antenna mount. I have my receiver and Mamba ESC mounted on top of the Stiffy.

How is everyone securing their batteries? I have a Thunder Power 2100 3 cell that I'm trying to hold in place without much success at this point.

[BitHed]

...LUW thats the ticket :D And just make a hole for your antenna mount and you are laughing :D The STiffy looks SO much better in pictures than in real life :o

[FHM101]

If you are using the rear motor option, couldn't you swap your steering posts and mount the servo using the front motor slots with something like a set of laydown mounts from an 8th buggy or AE or Losi electric truck/buggy steering servo mounts? You may have to fab an adapter to get the spacing right, maybe a CF plate with the servo mounts attached that had holes in line with the inner motor slots?

[LUW]

Looks like I'm getting along! I already intsalled the stiffy plate:

As you can see, I put the shinny part of the stiffy plate facing down, and not upwards like everybody else. That's because Bitty gave me a plate with a small cut already made on the left side, so I just made it bigger so that the slip gear didn't touch the plate, but the cool shinny side is out of view.

Up front it was easy to install it, I just unscrewed that trianglar piece that goes over the steering columns and put the stiffy under it. But at the rear I had an issue. Part of the wing base has this "tail" that goes down and hooks to the rear torque bar. So I made a longitudinal slot on the stiffy, crammed the piece on to it and screwed everyting in place.

And I think I solved the servo placement problem, and at the same time solved the antenna base issue: I used the stock parts. The antenna will stay in stock position, and the servo, supported by the stock servo braces, I'll only need to glue it down with shoo goo.

[LUW]

I also shoo gooed the esc on the stiffy.

So I'm basically done. I just have to wait for my steering servo to arrive in some weeks (HUGE thanks to Tim/leapingbug ;)) and I'm back on the saddle again. And then, more aluminum goodies :D.
