Yes you must run all 3 braces.

Ok thanks.

What do you racers consider the right amount of torque for steering? I have a couple savox 1267 and ae ds 1015 that I'm not using, would they be ok or do I need something in the 300's? I think the 1267 is 277 @7.4. I think I'm going to run a hobbywing, now how do I get the extra voltage to the servo?

All I know is im going to use a novak glitch buster with my 7955TG. I'm not sure if the same will be a 100% for you since your voltage requirement is 7.4V, and the hitec requires 6V. I'm sure other, more experienced people can give you a good insight.

for the aluminium tekno servo horn, what size wrench do we need? 1.5mm?

You could try your servo rated at 277. If it seems like it struggles to keep the wheels in position while steering through turns, then you'll need something stronger.

I've heard you want a minimum of 300 on truggies. Their weight and size can overwhelm a servo that's designed for lighter cars. I personally use servos rated over 400 on truggies.

I've never used a Hobby Wing ESC, but I would assume the internal bec it has can be adjusted just like most other brands that are available. The owner's manual or you tube should make adjusting the bec pretty easy.

Thanks as always!

You would have to run an external BEC to get the full 7.4v to the servo. The Hobbywing controllers don't have adjustable BEC like the Tekin or Viper. I think 250 oz is the minimum for truggy use, 300+ oz is optimal.

Not too long ago we were running monster trucks with 100 oz "high torque" servos. Those were dark times, the more torque, the better. :nod:

So I was going over the manual today (In advance, due to excitement, lol) and I have a few things id like to ask/gain a bit more knowledge on from people who have already built it:

1) Page 5 - steps on both the gearboxes basically - It says to have a perfect mesh alternate between having both shims on one side, if not good then one shim on each side, if still not good both shims on opposite side. So as a general consensus how has everyone been shimming the diffs in the gearboxes? One on either side will suffice? Or does shimming differ from each individual kit?

2) Page 8 - The note on reaming - Is that really necessary? Has anyone here done that?

3) Page 20 - Shock length also know as droop - is this 120mm measurement from top of shock cap to bottom eye? Also I have read people discussing droop on this thread recently and how they adjust it etc. So HOW really do I adjust droop/shock length? By the shock adjustment nut? Whats this people talking about "you can only adjust from bottom" and "I use rc8t droop screw etc so I can adjust differently." I dont get what people are talking about here. Someone explain please?

I'm sure you can already tell but just to make it clear this will be my first time building a kit so please don't get annoyed by my rookie questions.

The rest of the manual seemed pretty straight forward. I get more excited to build it every day.

So as a general consensus how has everyone been shimming the diffs in the gearboxes? One on either side will suffice? Or does shimming differ from each individual kit? My kit required 1 shim on each side for the front and both on the ring gear side for the rear, this will depend on how it feels when you build it.

2) Page 8 - The note on reaming - Is that really necessary? Has anyone here done that? I did not have to ream the arms, I only had binding when the toe block bushings were not pressed in all the way. I used a C-clamp to press the bushings in all the way. After that, the suspension arms moved free.

3) Page 20 - Shock length also know as droop - is this 120mm measurement from top of shock cap to bottom eye? Also I have read people discussing droop on this thread recently and how they adjust it etc. So HOW really do I adjust droop/shock length? By the shock adjustment nut? Whats this people talking about "you can only adjust from bottom" and "I use rc8t droop screw etc so I can adjust differently." I dont get what people are talking about here. Someone explain please? Droop is basically how far past the bottom of the chassis the arms can extend. The droop screws limit this by stopping against the chassis before the shocks reach full extension. At minimum, the droop screws should be adjusted so they stop the arms at full extension of the shocks. This prevents the possibility of the shock end being pulled off the shaft. The kit droop screws are installed in the bottom of the arm and you would have to flip the truck over an compress the suspension to unscrew the droop screw to adjust droop. The RC8T screws have an additional hole in the top for a hex driver so you can turn the screw without flipping the truck over. I'm sure someone else can explain the tuning benefits of droop.

I'm sure you can already tell but just to make it clear this will be my first time building a kit so please don't get annoyed by my rookie questions.

The rest of the manual seemed pretty straight forward. I get more excited to build it every day.

No problems, all reasonable questions.

What wheels do you racers prefer? I am trying to phase out my aka and proline in buggy because I dont care for either, but I havent run truggy in 7 years. I ended up getting a BEC for one of my Gen1 RX8's and the hitec 7954. Which has identical specs to the 7955 at 6v but is a HV and goes up over 400oz at 7.4v
-I talked to Dave @DE racing last week and truggy wheels in all the fancy colors are in the works

turtletrax 04-15-2014 12:05 PM

Never mind....ordered one

I am running the Tekin 2000kv Gen 2 motor in mine. Love it. :nod:
