    Whatever turns up in the Koford box stock set-ups.

    One interesting aspect on G12 came flitting through my in box this morning - As you guys probably know, in addition to the hawk 7, JK also has a "Hawk" motor, with removable endbell etc. This week it is announced that JK now have an all new endbell for this designed for full length motor brushes and "american coms" also a set of Neo replacement magnets. Hot on this announcment, Koford are making a G12 armature to fit this set-up. Sounds like an interesting combo - light, compact and quick - Now I just have to wait for the armatures to arrive and testing begining.

    What's the stock arm dia in the hawk? What do Koford have to do special to fit a X12 arm in there?

    Found my own answer: http://www.koford.com/slot/pics.html

    Hawk stack diameter is 0.513 and stack length is 0.395 but the actual armature length (front of com to back of rear spacer) is 0.905 so I guess shorter than a standard G12 which is think is 1.075

    Just called Paul Pfeiffer to order some Cahoza carbon fibre rims. If these last a long time, the tolerance is down to .0027", so they are quite true. I ordered the .394" diameter and the .787" width. In the long run, I think these may be a good investment...they cost more, but more accurate. My experience with magnesium hubs lately has not been good. Only about half of what I get are reasonably true, and lately the set screw holes have been drilled too close to the edge of the hub so they strip out really easily. I'm hopeful these CZ hubs will work out better. I got em in 3/32" axle only. Unfortunately the 2mm hubs do not come in the .394" diameter, only in a larger .422" which I think is too big for cars running 44T 80 pitch spurs....I start at .650". Report to follow in a few weeks when I get my hands on these new rims.

    Paul, you have way too much time on your hands!

    BTW: Meagan is having her party at the track on Sunday. I'll try to get some photos for you.

    Very interested in your results with these. The great thing about carbon fiber is that it's ether true or broken, nothing in between. Why are they only .787" in width? Shouldn't they be .800"?

    Perhaps the slightly narrower width is to allow you to insert a .013" Carbon Fiber Spacer on each side... I would guess...

    You're right Gary... way too much time on my hands. I have no tools & no toys to build here!

    Get that Carbon Fiber Body on Meagan's Carbon Fiber Womp for next week - I look forward to seeing pics of her racing party!

    Hey Slotcar Racer - you've got some catching up to do! We've run away with your thread!

    The run-out on the carbon rims are better! The one draw back on the "carbon fibre rims" is that when the take an impact they tend to crack and break (usually the glue holds the broken piece until you go for the retread) Other than that they are great!

    On a completely unrelated note: my carbon fibre wallet has lasted for the better part of 10yrs! (slightly frayed on the edges though- leather trim failure)

    Any advantage to the narrower rim? I just assumed the narrower rim would be a disadvantage, but that's what I get when I think and not test. I believe the Speedshop rims are right around .810 wide so were are talking about a pretty big difference of .023.

    Yeah Kevin, Jeff was very persuasive. I need to give Howard a call and let him know I haven't eloped with his loaner controller. Actually, I think I will need to get back up to Frank's this Saturday and put in more time. I want to see if Howard can fill the "sensitivity gap" on my Speedshops too. I know he did a great job of working on a CZ controller, an older one, that Hermanator now loves. I saw the Hermanator last Sunday, we had some fun with F1s on the Testarossa. Anyway, if Howard can't figure out the Speedshop sensitivity gap, then next stop is Mazur.
