JConcept Rulux wheels, B44 hexes, Tamiya axles
I've done the search and read all the answers and I just want to once and for all sort out all the info about mounting JConcept Rulux 4wd front wheels (3307), Team Associated B44 hex (9750), Tamiya axles, and getting them all to work properly together.
I must state that I'm using the regular universal driveshafts (part number 54015 which fit on DB-01, DB-01R, TRF501X, TRF511X and TRF502X) - NOT the wide angle universals (part number 54118) and NOT the original DB01 dogbone axles (9808152). So far, I've drilled out the hexes to 5.0mm and they fit well onto the axle, but they cannot go far enough on the shaft (before hitting the bearing) for the holes (on the hex and the axle) to align properly. I tried taking out the aluminium spacer tube between the two bearings, and that allows the hex to go deep enough for the holes to align and I can fit a 1/16" roll pin in there (Associated 7369) but without the spacer, the bearings are rubbing on the insides of the knuckle and there's a slight but noticeable increase in friction. Also, the 1/16" roll pins are a loose fit in the 2mm hole on the axle, so there's quite a bit of slop there. My next steps are going to be to try and make new (very very slightly thinner) spacers to go between the bearings and mill a bigger 2.0mm hole a tiny bit further in on the hex (but there's really very little material left there) and I'll then shorten some pins to fit on them. This may or may not work. The difference in distances are so tiny that I can't measure them with a caliper, so it's all going to be experimental and I'll post up what I did and what I get in the end. For now, what I want to say is... my experience trying to get the Rulux wheels to work has not been a painless one. If anyone else has a different experience, let us know how you did it and what axles you used.

I had a much simpler solution to running Rulux wheels on my TRF502. All i did was dremel the back of the wheel so that the hex wasnt as deep just like Losi and tamiya front wheels. Took less than 5 mins and i ran them on my car Sunday and had no issues at all.

Even more simpler!!
Take a M5 washer as a spacer and bingo. No work, no costs. |

whats wrong with tamiya rims?
if your talking about availability, you can get them shipped from Japan or HK and the worst you will have to wait 2 weeks, and best 4-5 days. |

If you read the whole thread you will see that Sim wants to fit rulux wheels. As far as im aware, Tamiya don't make rulux wheels, rulux do

some people still fell the need of design in racing buggies and especially wheels and JConcepts are the only brand apart from Losi that also offers NON Dish wheels as far as i know. Losi is not the mot popular company here in Austria for example and that mnakes it hard to get parts. So the Rulux wheels offer a welcome change in design of wheels.

sim, i did exactly the same thing as you did, to make the B44 hex work on the tamiya axel, simply bend the axel pin into a bit of a "cresent moon" shape and you should be able to tap it in no problems, ive had mine like it all year without one issue

there are two problems in my opinion with spacing out the wheels, you end up widening the track of the front end (its only marginal and probably has minimal effect) but u lose the benefit of the deeper hex, the reason j concepts went with the deeper hex was to prevent the stripping of the wheel hex that was happening in the losi cars, by spacing it out ur giving the hex less material to transfer the power through.most people will say they havnt had problems, but if u have the b44 hexes anyway, just bend ur axel pins a little and theyll work fine, and u'll never have to hunt around for lost spacers 2 mins before ur final when ur doing a quick tyre change

That sounds good. We've already stripped a few wheels
Can I ask do you use the original Tamiya pins with the B44 hex or do I need these too? http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWAX:IT AE B4/B44/SC10: FT Solid Axle Pins |

Any tips on how to drill out the AE hexs so they fit the DB01R axles?
Also, the original Tamiya pins are too thick, should I get the AE ones.... http://cgi.ebay.co.uk/AE-B4-B44-SC10...item20b6c2a7b3 Thanks for any advice |
