Marc – thanks for the technical/historical update : )
"... get on your bad motor scooter and ride!"
Sammy with MontroseThe front-wing’s magnet or Clip assembly is T I N Y.
I have seen recommendations to sand the paint on the nose and wing to improve the ability of either the magnets or clip to work. ShoeGoo has also been recommended (I would use a Very light drop).The rear wing … is also very flimsy, I plan to use either Styrene or thin Piano Wire to re-inforce it.
I cannot determine what chassis is better – the default flat one for the Chip appears strongest.
The front axle is adjustable, but they only ship Two 4mm Grubs with the car (WTH?)I plan to experiment with NSR front Zero-Grips (for the NSR F1-86/89 cars).
The rear wheels are very hard to remove from the rear axle for tire truing.Very pretty modern style cars … but it’s going to be interesting to see how Durable they are 🙂

Sammy with MontroseTA RADICAL –
— I too am interested in the nose-wing magnet-mount methodThese are the official parts: https://slotcarcorner.com/products/sicn10-slot-it
Slot.IT SI-CN10 – NEODYMIUM MAGNETS FOR MAGNETIC SUSPENSION 6X1.5MMSI-CN08 and 09 are also available for $6usd; as well as Sloting-Plus SP118001 for $4usd.
— Rear Wing – we may need to add some parallel Styrene supports and ShoeGoo them to the stock uprights.
ShoeGoo looks messy but is less brittle than using CA and easier to pull off and replace.— Relate Article https://www.hrwforum.com/forum/-1-32-scale/74289-f1-monoposto-policar-info

Sammy with MontroseSTAB – lights on or off (night runs)? Snow or sand? will vino, cheeze and quiche be allowed?

Sammy with MontroseSee this video. At 5.38min it shows how commutators and brushes interact to make the rotating electromagnetic field that pulls/fights against the perm magnets in the Can. https://www.youtube.com/watch?v=CWulQ1ZSE3c&ab_channel=JaredOwen

1 The shallow depth of the NSR crown teeth, presses the motor shaft disproportionately against the Thin (0.50mm) “guard-flange” of the Centering Channel.
2 With the Aluminum shank crowns, the guard-flange wears quickly, shedding AL dust and distorting the shape of the Centering Channel.
3 After less than an hour (on a rolling-road) the crown’s mesh has changed (the teeth are alternatively pressing harder/loser against the pinion). Friction increases noticeably.
4 The NSR brand Brass/Bronze shank crowns take over 45 minutes before they start shedding from wear on the guard-rails. The NSR Brass/Bronze crowns also have a (0.50mm) guard-flange.
5 The Slot.IT brand Brass/Bronze shank crowns have a (0.75mm) guard-flange. After 30 minutes on the rolling-road, the Slot.IT Brass/Bronze crowns seem to have little shed, and NOT degrade in mesh/lash (and hence performance.) The slight eccentricity from the Slot.IT having a larger diameter hole 2.38mm (2.998/32 inch, 0.09370in) vs. 2.37mm (2.9858/32 inch, 0.09331in) for the NSR axle, does Not seem to have any obvious consequences.
6 Russ’ solution to use the OEM brass spacers, and Trim the shaft so that it no longer contacts the Centering Channel – seems to be an easy and viable solution.from Mark:
The wear issue appears to be either a flaw in the Design of the Crown’s teeth (too shallow) or in the Manufacturing during alignment on the Shank (computer parameters mouning the crown on the shank too close to the centering-channel). The skinny 0.50mm Guard-Band also seems like a Doofus design choice with no apparent cost/weight/performance benefit. Note that most NSRs are either short-can pseudo-sidewinders (2deg AW) or long-can angle-winders; so their overall experience with Inlines seems limited (e.g. only ocurrent models with ILs are Mosler, Clio, Abarth, LMP, F1)
In conclusion – I join John in (a) requesting that both (a) the Slot.IT crowns (b) and trimming the motor shaft be Permitted."... get on your bad motor scooter and ride!"
Sammy with MontroseJohn – please post a picture of your rollers/rolling-road !

Sammy with MontroseSimple Solution to excessive NSR Crown Channel and Pinon Wear (paraphrased from Russell’s email)
The OEM brass axle spacers on the outside of the motor pod bushings reduce movement of the crown gear “landing” or “channel” for the Motor shaft. With the spacers against the bushings on one side and the wheel on the other, the axle has very little side to side play. The crown can then be set-screwed in the proper location for best gear mesh.
Additionally: you can trim the Motor Shaft to prevent Any contact with the channel on the crown.
ALTERNATELY: “Axle Stop-Collars” like the one below the chassis in this picture, can be used on both sides instead of the brass spacers. The effect is the same, except the Stop-Collars must be carefully adjusted with an allen wrench to prevent too much friction with the bushings.
// JOHNS ISSUE REPORT //
After having major wear issues with the NSR aluminum-collar crown gear last week in practice, I installed a NSR crown gear with Brass collar. One thing I see is that the Valley-depth of the NSR crown gears (alloy or brass) forces the motor shaft against the left flange of the crown. That’s why the aluminum crown was so worn even with lots of grease. After carefully moving the pinion to allow clearance, it appears to work ok after about 45 minutes on the test roller. The brass NSR crown gear shows signs of gear teeth slightly binding as it did with the aluminum gear. Are other racers having the same issues with your NSR F1 gears?I also tried a Slot.IT Brass-collar crown which is only .001 larger in axle diameter than the NSR. I ran the Slot.IT crown gear on the roller for 30 minutes at 4 volts. The fit and mesh seem far better than the NSR. See no vibration or out of round issues with the Slot.it gear.
I will put it on track next week. If it works, I would like to Propose the rule allow Slot.IT crowns.
I want the F1 series to be successful.Lotus Jr.
