Default Kahuna's Build

I thought it was time to finally post up my Losi after a sad failure with the cast Bullys. The Bullys were bullet proof just to heavy for me.

Thanks to all the previous builders this rig was by far the easiest to tune and build.

Here's the specs

Hitec 7950 for steering
Kopro 949 for dig
MMP
CC BEC wired straight to the servo
1" SLW .675 / .475
Novak 21.5 17t pinion
Lungsford Links and Steering
NW Traction hybrid reaches soft fronts/firm rears (lol firm rears)
Losi shocks 32 1/2 front / 22 1/2 rear 15mm / 11mm
Panther Cougars

The rest is mostly stock, no need to upgrade.

Here's the pics

With body


and now naked


rear articulation with the shocks inverted and not binding


Close up of the lower shock mount


Shot of the lead tape rap I'm trying for a static mount on the axle

you have any problems with the 7950 wired to the servo? I had mine hooked up that way runnin 7.4v to the servo and the servo would spaz out whenever the front tires were up against a rock

how is yours setup?

I have both earth and hot leads from the BEC to the servo and only the signal wire is connected to the Rx.

No glitches yet, knock on wood though.

Yea thats the way i had it hooked up, So i set cc bec to 6.0v and ran it thru the rx and no glitches, not sure if the servo didnt like the volts which its rated for 7.4v, It was a major headache for me Good luck

Hey Sean,

Lookin good. You are correct about your Bully weighing too much. I think that you might want to try a battery with a higher c rating as the Losi will probably puff up that 20c batt.

Are you going to Teds with this truck on Friday? Do you have a MOA kit for it yet?

Ran this for a bit, as long as I don't run them past the 10m mark they seem to be holding up.

Still deciding if I will convert them into 4s like my other cells

This rig works very well. Some really neat stuff done to it which seems to make it a little more agile while still being very stable. With a little more work this might be a very hard to beat truck, regardless of the driver, lol.

Figured I would update the build

Steering works for now, but I need to pick up some stainless



I call her the O.D.B. Chassis.
Wanted something with a high break over clearance








Bodies is alright, may change it out after I get back from Australia



Lastly the flex shot
