Single Servo mod:

I have run this mod for over a year and a half of heavy bashing with no issues, Bondo even longer. It is not recamended to run this mod with out the Bad Ass Creations Steering link as the removal of the saver and second servo adds stress this part.

Pluses:

1 - Monster torque, 333oz or 416oz with optional BEC
2 - Extreamly tight steering, due to the no springy servo saver
3 - Very quick steering, .17 and .14 respectivly
4 - Weight savings, only one servo

Minuses:

1 - Some have reported broken stock bellcranks with this set-up but it is very easy to switch the servo to the other one and stock bellcranks are cheap.
2- Racing applications, you lose the back-up of another servo to finish the race on. Alltho doing this will very quickly burn up your remaining servo.

First, remove your old Twin servo's, savers, links and balls.(notice I am running GPM aluminum bell cranks in this picture. It is recomended that you not run aluminum bellcranks with this mod since you are eliminating the servo saver, and the stock plastic bellcranks provide a bit of flex to protect your servo. But there are a few people who do this and report no issues, the decision is yours)



Install your Bad Ass Creations steering link acording to the included instructions.

Next dremell a bit on your bulkhead pin brace to allow clearence for the Jato link at full turn. I just used a sanding drum for a few seconds, it dosn't require much.



Then install your new Robot Servo, henceforth refered to as Bad Ass Servo. It dosn't mater which hole you put it in.

Next, you will need to cut down the Jato link rod so that you can completly screw both ends on so they touch. You can dremmel a bit off the ends so they are a bit shorter if you want the servo arm and bell crank to be perfectly perpendicular but it is not necessary.

Next, intall the fisrt end of the Jato link with a 440 x 3/8 screw to the corresponding bellcrank.

Next, turn on your radio and reset your EPA's to zero and zero your new Bad Assed Servo.

Then, install the servo arm so that your Jato link lines up with the outside hole and install another 440 x 3/8 screw (use locktite on this one) into the servo arm.




Adjust your travel settings so that your new Bad Assed Servo turns Lock to Lock just barely touching each side so no servo whine is heard.

Your mod is now complete. Now go impress yourself and all your freinds.*

BondoNutz runs his servo off the Mamba Monster ESC which provides 6v (the same as a standard reciever pack) and is plenty to power this beast to 333oz of torque.

Now if your hardcore like me, the servo can handle 7.4v so you install the BEC and get 416oz.*

FOC Conversion:

TiNi Gear is installed on the top shaft to gain additional topend, I've just started doing it to all FOC tranny's. You must loctite the screw that holds the pinion gear well...Take this opportunity to shim your topshaft for no slop.*





Slight dremel work done to case halves to make the gear fit.







I like to stick this top plugs in while the case is apart, they are difficult but you can do it!!

Foam Bumper mod:

I can't remember who originally came up with this mod, but here it is.

You need some pieces of very stiff but still plyable foam ( this stuff came in my TV Box) and you cut it to fit inside your front and rear bumper between the bumper and the brace like this.





The boy runs into stuff at full speed all the time and the braces have yet to show any sign of damage.

These are the most usefull ones I think, I have some more small ones, I will post them if wanted.
Like how to make dish wheels look better, cleaning a Mamba Monster, some conversion/battery info by Bondonutz, shock tuning by Bondonutz, A home made tire balancer, a huge list of helpfull sites etc.
Hope it helped you guys, as much as it helps me!
