Hello all, I was wondering if anyone on here knew where a person could get a hold of the longest 1/8 scale dogbone/driveshaft avaiable? I'm looking to build a FOFF out of a exceedrc madstorm with solid axles and such, but need a longer driveshaft to go from my center diff, which will get locked eventually, to the axles. Any input is appreciated. Thanks

let me tell you this converting a indy truck to solid axle is and will be expensive i have a custom solid axle short course truck made out of a Kyosho MP5 and i have about $2k into it if you include the price of the mp5 originally but i got it for free but still have around 1500$ into it and it still cant run, needs more parts still...


me personally i would just get the kyosho foxx like i linked in your other thread will save you ALOT of time and money in the long run...


also random question if you are still interested going the custom route. how much experience with rcs do you have and any machining experience? cause what you want to do WILL require atleast fabricating a few of parts(indy suspension lockouts,4link mounts,etc..) or just spending countless hours trying to find the parts that "Look" like they'll fit but they are really not even close in person


hate to burst your bubble but this will save you some cash... that 180$ may seem cheap for the madstone but by the time you lock out the axles(and turn them into solid axle) get a tvp chassis, different center trans, driveshafts will be way over 600$ and still might need more or different parts



may not look like it but this is about $1200 there in this pic(have a nice body with some addons(that costed around 250$ or so)







now tho unless you have already started on your project.. first thing is if the output shafts on the diffs are 8mm and 99% of the time the output shaft on the center trans is only 5mm


this is the longest/cheapest/most durable drive shaft i could find when i set out and made my truck

have ran it on 4s has a tiny bit of slop but never got looser after the first time i ran 4s on it


also will need these and be able to drill out a side of it that the set crew from the driveshaft can fit through

those make it so you can stick a 8mm driveshaft ona 5mm output(but they NEED to be modified first)

Instead of trying to find a longer dog bone you can make one out of the existing dog bone. Simply cut it in half, insert each end into the appropriately sized steel tubing (brake line works well) and weld them together. If you don't have a welder or know anyone, a welding shop shouldn't charge too much to do the work. Brazing is an option but requires a torch. I've seen shafts soldered together using brass tube but that's a real pain and requires a really big soldering iron or another form of indirect heat.

You would be better off ditching the doc bones for a sliding shaft or cvd's though as they'd be less likely to fall out and get lost. Traxxas Summit axles are pretty tough and can be cut down or lengthened for different applications.

Sorry for the late reply. I like the shafts that taco put up, they seem good. I have some fabrication experience, I have made up an entire roll cage for the said beast of mine... have it bolted on instead of just on the body posts. I was going to make body panels for it, but decided against it. So I think fabricating 4-link mounts, brackets, a-arm lockouts, etc won't be too difficult with the right amount of homework on my part. I have scrapped the idea of using crawler links from the madstone based on how much effort it would take to make my own links. Would much rather make my own with revo link ends, plus that way I can get the wheelbase that I need. Those sliding shafts would make that part a breeze haha I'll definitely take a look at those summit shafts to see if I could use them. I have to look at the output shafts on the center diff to make sure it's 8mm or not. I know the shaft on the diffs are 8mm though, and would like to say that the center is the same, but I'm not 100% certain. I'm thinking of making a bracket of sorts to mount up my bottom links under the chassis and making a different bracket that will mount on to the top of the chassis for the upper links. I'm going to be buying another aluminum chassis to hack up for the foff so I can get proper clearances for the links/ shafts. Will probably have to relocate the radio box, throttle servo, fuel tank etc so it everything can fit properly. Hardest part is getting all the extra parts for it, and I have a hobby shop near where my son goes to karate that will carry most of the parts I would need for creating the links, and it wouldn't surprise me if they have the shafts I would need... But probably much more expensive than online. Then Canadian tire for all the metal materials that I would need for brackets, etc. Thanks for the help and input guys, much appreciated.

ps taco: that is a sweet rig you got built there
