Interesting investigation! Thanks for sharing!

Thank you Jim, a very informative test.

I tried this today Jim, amazing difference, snappy acceleration and braking. I have a technical home layout, very impressed with the outcome, noticeably quicker. Thank you for sharing.

4 laps hell yes I'll take it !

I use nylon axle shims for both the rear and usually a .05” for the front axles..

Thanks for doing the hard work for me Jim. Now to just find it on eBay =)

I never realised the weight difference between the stock/aluminium setup. This is definitely something I’ll be trying soon 👍🏻

Interesting results Jim... I've never tried to measure this as you have.

Good stuff!

I had so much trouble with aluminium Spurs grinding away and the gears chewing out ,I went back to brass with less problems .

Even allowing for WANTING difference this vindicates my thoughts on this. I also balance the wheels and gear, and run a dial indicator on the gear to ensure it’s true 90º and concentric to the axle.

It would have been interesting to see how the lightweight rear with the motor shaft still intact and without the axle stoppers would perform

Just a question that is bothering me. If you are reducing the rotating mass of the axle and gear are you not defeating some of the reduced weight by using axle collars that add weight? And by reducing the friction from the motor shaft and gear collar contact do the axle collars not add equal friction? Not being critical just curious.

Not if you use lightweight collars and .2mm aluminum spacers and a drop of oil.😉

The reason why axle collars are better than using the motor shaft to keep the gear in place is explained in the Slot.it FAQ N0.26 which explains why we developed the 'M' crowns. Simply, the motor shaft and the groove rotate in opposite directions when they are in contact. This is much reduced if you either use collars (if allowed and if the groove of the crown can be modified by your club rules) or 'M' crowns

@@roarr62 Seems like the M crown is an incredibly complicated solution when a simple collar mounted externally on the left hand bearing or internally on the right hand bearing would achieve the same result.

how much rotating mass can an axle of .093" diameter have?

Doesn't make sense. You lightened by an alloy hub spur and hollow axle, yet added back onto the rotational weight 2x axle stoppers. What does the actual rotational weight weigh with these two axle stoppers as well, as they are included in the physics of your rotational weight. If you had of used 2x bronze bushes each side instead, then the weight would have been less as the formula would have changed due to bushes doubling positioning as spacers

The aluminum hub gear saves 1.6 grams. Both axles stoppers (with set screw) weigh .3 grams. Net savings of 1.3 grams not even counting the axle. Bronze bushes weigh more than the axle stoppers, plus the axle stoppers won't be affected in a crash if the wheel is pushed in.

My name is James and I would like to know if an 1/28 scale AWD drift car can run on a racing track and if so how

Any car can be “slotized” but 1/28 is not a common scale in Slot Car Racing, most raced scales are 1/24, 1/32 and H0, RC is totally diferent from Slot Cars, I’d suggest to pay a visit to your local Slot car club, you’ll see and almost sure, you’ll get hooked into the Slot car racing😉
