I just ordered a Junfac center drive shaft. Curious how it will hold up. Junfac Hardened Universal Shaft 95 130mm 5mm Hole 90032 | eBay Junfac page Hardened Universal Shaft (95-130mm) 5mm hole [J90032] : JunFac.com I know, it's for 5mm output, but it will not be a problem to adapt it for 8mm on a lathe. |

Been using Junfac shafts for years in my 2.2 rigs. Only ever used Revo shafts in my big rigs, or 1/8 scale shafts.

Thanks to cmbscx10 I've got my version of cvd on my old Mad Force. I used a pair of Losi XXL CVD's cut to the length and connected with a bushing. However I need to fabricate a thicker bushing, as the one you see was too thin and the set screws didn't hold up, it need to be at least 3mm. And you need to grind the axle where the set screw sit on the axle, kind of how a driveshaft is connected to the pinion. Or you can weld it together, if you know how to. I tried and I didn't liked my result Last edited by Tzicul; 11-21-2016 at 03:44 PM. |

Bottom line is I wish custom shafts in Uni or CVD flavor could be ordered and I think the vendors like a super Shafty and machinists are listening. Let us know how your new idea holds up Last edited by cmbscx10; 11-22-2016 at 11:20 AM. Reason: Added photo | |

| Re: *** Twin Force Upgrades *** Hopefully not by me. The pulse DS are 88mm which are 2mm too long for the short side. Too bad cause at least they are 4.5mm shafts. I spent a shirt ton of $$ finding out what doesn't fit and what does.

A little more research can be done for a cheaper price maybe but since you have the Stubs form the Pulse DS i woudl get these Kyosho 1/8 Inferno MP9e TKI Center Universal Shafts – Dollar HobbyzKnock the pin out. ditch the pinion shaft end and put your Pulse stubs on. The long DS is basically trash unless you want to cut it down. | |

I thought about cutting it down and welding it at school

RC4WD just released some knuckles. Is there any benefit to these? Are the stock ones weak? Aluminum Steering Knuckles for Kyosho Mad Force |

I have read quit a bit on the stock knuckles and short of clearancing them for steering angle if you have Uni's they don't seem to break or have a lot of negative comments on them. $33 plus shipping buys a lot of stock knuckles but that's my .02 end of the year bonus. | |

Didn't had the chance to try them furthermore. Hopefuly this week/end. But, compared with the first version, they are bulletproof. Consider this tipe of connection is commonly use to rotate a differential, hence two wheels, so why wouldn't it resist to only one wheel? Sent from my Sony Xperia Z5 |

| Re: *** Twin Force Upgrades *** One and a half year later... and they are holding strong! Thanks cmbscx10 for the tip, using Losi LST driveshaft. And if we are talking about this, there are my latest upgrades. For the rear driveshaft it was pretty straight forward, only had to reduce (on a lathe) the output of the pinion from 8 to 5 mm 27797665_2250185201662195_657458035193025862_o by Serban, on Flickr For the front driveshaft I had to fabricate that small piece of metal, nothing too complicated. At this moment, the only difference compared to the last picture is that I'm not using that Junfac driveshaft, but I have on both ends the RC4WD ones. However, I'm not very happy with them, after not even 2 minutes into the first run, the rear driveshaft (the only one installed at that moment) fell apart in the snow. Luckily, I was able to recover all the bits and pieces from the snow and rebuilt it. Furthermore, if you look closely at the rear driveshaft, I manage to fabricate a protection for that little pin that fell apart. It's made from 12mm copper sleeve, painted in black so it's hard to see (it's what you use to connect two copper pipes). The thicker pin stay in place just fine, no chance to loose it so there is no need for a protection. 28071345_2261663467181035_7286519468941265187_o by Serban, on Flickr 28162024_2270927476254634_2540872341883534830_o by Serban, on Flickr Last edited by Tzicul; 06-02-2018 at 02:13 AM. |
