The 2 problems I have found with the wheel hex are as follows:
1. The aluminum is WAY too soft. Give it 3-4 good race days and you will see where the hex starts to round out on the inside causing slop.
2. When you go to tighten the set screw on the hex the whole hex wants to tweak the way you are tightening it on the axle (cause of the slop). At first you dont really notice it but once you put your wheel on and give it a little throttle you will see how much the wheel wobbles.
The only work around I have come up with was before tightening the hex set screw, put an old bearing over axle and then install your wheel nut (without the wheel), tighten wheel nut so that it pushes the bearing into the hex and then tighten down the set screw. The bearing helps align the hex on the axle but even doing it this way was not perfect.
I like the keyed axle idea but the hexes need some refinement.
I'm going to go back to my stock Kyosho swing shafts and FLM axles. Never had issues with that combo.
Just my $.02

Please keep me updated after you have a chance to run on them for a little and let me know how they are holding up.
Thanks!

help guys - The current (if I can find one) Ultima SC-R SP. I have never owned a Kyosho SCT. Is this kit worth the money? OR wait for I guess is a new one coming soon? If I buy an SP - what upgrades do I need right out of the box? Thanks.

I have been making some tools for kyosho cars for a couple months now and would love to share them with as many kyosho drivers as possible. The first tool is a kyosho shock tool for removing the shock cartridge, its a great replacement for the one that comes with the kit and strips out easly. It costs $12 in the u.s and 15 overseas. the second tool s a turn buckle wrench that has three sizes on it. the one side has 2 sizes in it that fit the kyosho turnbuckles as well as the lundsford and ae turnbuckle. it will also fit durangos and any car with a 4mm turmbuckle. the other side is 5.5mm and fits all kyosho 10th scale trucks, the losi 4wd sc and some 8th scale vehicles This wrench is $17 in the u.s. and $19 for over seas. if any of you are interested please email me at [email protected] as i am not always on the forums. thank you for your time and i hope to be able to provide some of you some great tools..

Mads- Kyosho has been out of SC trucks for quite some time. A new SC truck is in the works based off the RB6 platform. I already have some on order and they don't exist yet - heh heh.
I have a ton of Kyosho parts in stock as well, (not yet on website) so don't hesitate to call. Can't wait to rub fenders with you soon!
