| One Off No Prep Scaler
Build is shaping up quickly. I have dubbed it 'What-N-TarNation' though that has nothing to do with the Paint Theme I will be doing on the body. Should have it set as a roller by this time tomorrow, if not artr. I have a SW4/5700 here I am probably going to toss into it for now. have to get a servo. Have a decent Hitec here that should work out well. Its an older one, but its digital and pretty fast at 6.v and has plenty of torque for steering a drag rig. Traxxas TRX4 chassis rails. RCAWD (not rc4wd) SCX10 ii skid plat Atomic Front Shock Tower traxxas 2wd front bulk head Slash F Arms Atomic Castor Blocks Traxxas steering blocks 2 No name f and r aluminum bumper mounts/chassis braces SSD Wraith High Ratio Tranny Vanquish Top Shaft Vanquish Idler Gear Shaft Robinson Racing Idler Gear TA Slipper Fast Eddy Ceramic Bearings in Tranny and Backyard RC Ceramic Bearings in SSD Axle Traxxas bearings in front steering blocks Traxxas front turnbuckles SSD O.D.

This looks like fun, I always thought a solid axle drag car would be interesting, maybe not the absolute best but fun. Whats the front end from? |

Bandit front end from Battery tray forward. I trimmed it a bit mocking it up. Now that it is where it should be, I will get another bandit chassis and trim it to the needed specs so it fits better overall. But this will suffice to get it out making passes.

Solid axle is what the arb sway bars do....... my concern would be rail twisting. I remember a viscous 409 that literally twisted the whole launch Hang up and Drive |

With the Tranny being 1.83:1, and the O.D. gears being 3.5:1, I should be seeing about a 5.35:1 ratio not including the pinion spur. That could really open it up for some good top-end speed in 132'. | |

I am all for this! I can already picture those phat tires on that solid axle in the back of F100. Awesome work, looking great. _________________ https://www.instagram.com/island_crawlaz/ SCX10ii Yota TRX-4 Bronco |

This looks cool as hell, but I have to wonder if that axle is going to hold up to high speed passes?

Been at 1/2 a standstill. got everything installed, but a servo. Still haven't picked one up yet. But have one in my cart at Amain. Got the body trimmed out, still need to clean up with some sandpaper to smooth out the cuts. Then mount and paint the body. Been getting back to work so been busy and not taken the time. Will be doing that this next week while Im away for the week. Will swing by the local shop and see what is avail. just going to grab a simple servo. Maybe the new Hitec Drag Servo just to put something in it. I also want to mod the bulkhead and cut up bandit chassis to help fuse them into one piece. Hopefully will be able to get a servo installed and get a few runs just to see what happens. I thought the drive ratio would be lower than it is. Maybe I am missing something. The Tranny is the High Ratio tranny at 1.83:1. The axle is the SSD with the OD set of 8/27 3.375:1 For spur and pinion it has a 15p/54s which is 3.6:1" Should that not equal 8.8:1 FDR? Seems to be double that when I roll the tire one full revolution. Anyways, Once I get a servo installed, I'll take a few runs on 2s just to set it up, get it tracking correctly. Need to get a decent front bumper setup on it. May grab one of the new Traxxas Drag Slash front bumpers as it looks pretty decent and will help provide a little protection when she dirfs it. hopefully it wont. lool |

Twisted axles anyone? lol May need to get some 1/4 inch hardened steel rod and cut a couple new ones. maybe buy a couple good Cro Moly screw drivers and use that steel. if it does prove to be too much, I'll replace them and see if I can take out the diff gears next. lol True Scale Drag Shit 101. lmao But just to have the scale build with some details would be cool. Got an SSD motor I can stuff into it. Maybe make the hood lift and add engine bay details etc. Some zoomies and a through the hood blower off the top of the engine. It would look bad ass as hell I'll need to relocate the esc and rx next to the tranny to put the engine and maybe an interior for shitz n grins and run it for more of a show than competition if the axles have issues.

I can totally see scale 1/4 mile getting super popular. I'd love to see front mounted motors on scale looking transmissions, hard bodies, wouldn't that be something.

I’m not convinced that the solid rear creates any issues. I don’t hear of any dogbones twisting or snapping, and by adding the sway bar we try to act like a solid rear. Proper preload, I think it’s gonna be fine Hang up and Drive |

| Re: One Off No Prep Scaler Originally I wanted to use the SSD Tranny, but the DR on it is far too low. If it was a 2 speed, or could be regeared for a nearly 1:2 ratio wit the motor, that could be doable...

| Re: One Off No Prep Scaler Thats what I am thinking. Yet, twisted shafts are fairly common in 1:1 drags.

| Re: One Off No Prep Scaler I don't know about durability but the BRX01 2 speed tranny is scale-ish and is supposed to be pretty quick. That is relative to Crawler trannies in general so who knows if it would be quick in this application.

Ordered a RudDog servo for steering duty. It'll be here next weekend when I get back home from the week it looks like. Should be able to take some test runs. Time to get on the body theme. |
