Looks killer - Where did you get the lower control arms and shock mounts?

I use a nice little round machine file about 3/16 in diameter in most cases, I also start tricky ones with a triangle shaped file then to round, of course I also have the small set of miniature files from HF. I also drilled the tubing with a 3/16 bit where I needed it cut killing 2 birds with one operation. Are those TSS Robby Gordon Wheels? Very nice Last edited by rockhugger; 07-15-2013 at 02:12 PM. |

Rockhugger, Glad you like the work man I just use a Stihl 3/16 chainsaw file, a hobby vice and a hacksaw (400 wet and dry paper to finish). your method sounds more involved than mine, and by involved i mean smarter ha, I will typically cut tubes at the rough angle I need and leave maybe 2-3mm excess (eyeballing everything) vice and file it by hand, the compound joints take longer as I'm allergic to measuring anything I'm constantly offering up the tube to check alignment and adjusting when needed, just got to take your time I guess. Yeah they are TSS wheels, super nice fitment. I've donated them to my brother but temporarily used them for the mock up |

Amazing tube work! I've been messing around with my first brazed frame so I can really appreciate the talent and expertise required to build something so great. Inspiration to all us hacks!

The joints look great. It brings back memories and headaches from my southern buggy. Keep it rolling, it's looking great. |

really nice work on the Robby Gs Stang Killa, I have a lot of time for anything so faithfully scaled down. Its been said before but I'll say it again, they are awesome. The rings were just tamiya rattle canned btw. And thanks for the compliments. A break now and some head scratching as I mentally package the chassis mounted servo and panhard Last edited by Stone age; 07-16-2013 at 09:36 AM. |

| Question!
Ok I have a question for you guys: I'm planning a chassis mounted steering servo up front. Assuming a parallel panhard bar AND steering linkage; Does the orientation of the servo matter?? (laid horizontal i.e. most common OR upside down vertical and to the left) And when I say "does it matter" i'm talking in terms of bump steer/ max throw etc. I searched and didnt find my answer. Ive built dissimilar rigs with both but I'm looking to optimise this one at every opportunity. Input will be appreciated |

i would say that the longer you can make the links the better your articulation would be. particularly with straight up/down travel, the longer the panhard the less of an arc you will get when the axle travels. i try and put the servo as far away from the opposite side as is possible. edit: orientation shouldnt matter as long as it doesnt interfere with anything when it swivels, but in saying this, most people seem to mount it upside down, rather than on its side. |

I'd second what Klampy said. The lower the whole setup and the more horizontal the links are, the less ill effects of axle "Float" side to side. Long as possible is better too. The tricky part is getting sufficient travel without bottoming out. The setup I'm using on my new rig is using the VP geometry of the wraith CMS setup. Here is a link to how it works on the wraith. Vanquish Products CMS and Panhard kit review for the Axial Wraith - YouTube Here is How I modded it for my chassis. The benefit is that the drag link only goes from left to right and stays in the same plane as the axle. Also, this way, the servo horn stays out of the way of the panhard bar. I've tested it and had great success with both clearance and zero bump steer. I will say though this is setup for wraith axles and the vp cms/panhard geometry. If you alter the axles, this setup may not work for you. That's all I've got! |

I personally like to have the servo on the same side of the driver for scale apperance. You want the panhard bar (chassis to axle) and drag link (servo to knuckle) to be the same length and at the same angle. Both of these rods operate on an arc and bump steer results if they don't move the same.

Man... This thing is looking awesome! Just as I expected from such a skilled builder This is key right here. I have seen what happens when this isnt correct on a real rig. Its pretty funny! steering gear box gets ripped off the frame rail when trying to steer away from the flex Keep up the good work! |

So this weekend was a productive one. The font end was re build to accomodate the drag link and panhard. The solution is pretty severe, very 'function over form' but I love that. There are Trophy truck levels of suspension travel and the Rig is pretty squat at full bump so the assymetrical design allows the drag and panhard plenty of room chassis just need some more tabs for the servo and electrics Just realised I've not taken any shots with the steering/panhard connected. I'm still designing a Delrin mount for the axle/panhard stay Rear end will be complete once the tyre carrier is brazed on Bump and droop And finally the beautiful (if heavy) EZ LOC's Im running them with the narrow offset I dont want this rig to resemble an e-maxx afterall and this way round they remind me of the Ivan Stewart baja tundra rims |
