Allan,

Bravo for proposing a modern F1 Proxy Series. Of course, I have seen many historic GP Proxy races but never one for F1 cars from this century.

I have a number of Scalextric F1s from the era you have proposed, though nowhere near Alexis' collection of vintage 1990's Scalextric! I applaud your suggestion that a low-power motor become the spec motor of the series. Without magnets, the motors Scalex puts in these cars turns them into ballistic missiles. If the spec motor is to be a slimline FF can like the SCC Minnow, it should be a drop-in fit for recent Scalextric F1s. However, there is another issue. The Scalex releases prior to around 2004 were powered by the fatter FC-130 can. For instance, the Renault R23 #8 (C2398A) which models Alonso's 2003 championship-winning car, has the FC-130. Whereas, the Renault R24 #7 (C2581) that reproduces Jarno Trulli's ride from 2004 is the earliest car I own with the FF motor. All Scalextric "modern" F1's since then also have the slimline motor. The track width across the rear tires, shoulder to shoulder, is a touch under 58mm. Rear tire width on my cars varies from 11.5mm to 12mm, though I have replaced the stock tires with urethanes. The real F1 cars increased tire width and overall width for 2017. We'll have to wait and see if Scalextric's 2017 models (Williams and McLaren) follow suit.

I hope the above is useful.

The 70's-80's cars from scalex were much stronger than the current crop, much less prone to damage and have the great benefit of being very cheap....why not use them with standard 18K motors. Everything else free choice.
Makes for good racing on our Club Track.

This one OK only $39 preorder Scalextric

Looks a good car Austin. The thing with some of the cars is a difference in Wheels etc, even the newer ones such as the latest Lotus which had a extra long motor shaft, but the same motor and the Mercedes had smaller rims but bigger tires, but it all came out even in our club class. The benefit of using a less powerful motor is an advantage in control on these rocket ships. A very fun class to compete with. Open Wheel action and Paul Gage has tires for them too.

all MT-SL motors have 12.70 mm - 0.050oo in. 1/2" long shaft from the outside end of the bushing housing.

Mark os that to show the longer shafted MT2 that would work in the Lotus.
Bob

Thought the SL2 was no longer produced. Where would I pick those up?

I would think the If SCC has a lot in stock
M/T-SL1 Slim Can Motor
Slim can FF-050 housing
Perfect NC1 type replacement for many makes using slim can type motor
Rated at 14,700 RPM @ 12V, 77.4 gcm
Great lower performing motor for Classic type cars
Will work in MRRC and some Scalextric cars using slim can motors

Allan I while ago I sent you a F1 setup this way, you still have it ?

There are a pile of BWA ff050 and NC1 motors on epay by BWA at the moment .
Al Penrose has lots left if thats what you are looking for.
Bob

by god... I want to have a horse in this race, no matter the motor, and would also like to host a leg of it !!! on my woodie ...

Perfect F1 track!!!

Thanks Mark. Can you give me the length of the shaft on the FF050.
