Im thinking of putting a Scalextric motor into my SCX NASCAR COT just wondering if anyone has does this ?

Im am thinking if i use a standard Scalextric motor i will need spacers but was wondering if i use a Scalextric F1 or Bike motor as they are longer then i wont need spacers?
Do you need the conversion kit to fit any different motor into SCX cars ?

Does anyone know or have any tips on this

Why? SCX offer some higher performance motors, OR the SCX motor can easily be tuned to perform better.

hey pal , just seen these rx-4h , scx motors , maybe a way to go and no spacers etc etc

oh by the way thanx for the drill the other day car is flying

cheers

Ive never been a fan of SCX Motors

How can you tune a SCX motor to perform better other than running it in ?

There are ways to improve scx motors Rick at south city is a bit of a whizz with them but to tell you the truth i just run in a 42b if thats what you have and put on a 10 tooth pinion and find the performance the same or better than a scaley motor anyway. The 42 motor is a bit slow but the 42b 42c pro turbo etc all go up in performance. Ian at our club fitted a scaley motor to an scx car and it was pretty easy just using a "liquid" mount.( a liberal dose of hot glue or epoxy)

Do you know what Scaley Motor it was eg F1 or not a Long Can motor ?

Guess he used the Slot It adaptor ?

[oswald900]

Just checked the car and its got the RX42 motor in it GGGGGGGGGGGGGGGGGGGGGGGGGRRRRRRRRRRRRRRRR

[FLY in the wall]

I hate to mention these words but Slot.it has a plastic widget adapter for FC motors in SCX. The other problem will be can drive for SCX vs endbell drive for Scaley.

[oswald900]

Thats why im thinking about a Mabuchi in it but ill see how i can get the car going first

[FLY in the wall]

I did measure the motors and I think Scaley is OK for length but it is end bell drive so you have to do some mods as SCX is can drive. Typhoon would work but it does not resemble scaley so depends on regs if you race. If you don't race then....

The problem everyone has is finding an equivalent to scaley. If you don't race then slot.it green would be close?
Another idea would be FF shaft should be OK but performance would be better. Have a good look at new SCX offerings there is probably something there.

Want to go really quick on a budget? Little Ripper but you'll need a big track.

Now I just came back from the pub and Google has Google goggles which i could probably pass but SF does not.

A lot of cars were released with the 42 motor and it is good for small tracks but its a bit too slow for open wood tracks. We race 42b cars against scaley cars in lots of classes and there is little difference in performance with the black stripe motor once you put a ten tooth pinion on the 42b. The slim can scaley motors are another thing altogether they are way more powerful then either of the other two but a little more "peaky" to. I personally don't like them and think its a hard choice for clubs to allow them or not in classes whic allow the other 2 motors as they have a clear power advantage over the other types. As an aside Ian just liquid mounted a black stripe into his scx car and it worked very well. His car came with a 42 and he had black stripe lying around.

If you are just after outright speed get a RX-4H motor, 25,000 rpm, they fly and no messing about with spacers and glueing.

RX-4H runs at 27000 RPM so why would you want to put in a Scalex motor?

SCX build quality is very poor with 1 in 20 motors being much quicker than the specs above indicate. Fastest motor I have is a Turbo armature in a RX-42 can. It revs much harder than a Turbo Plus and the torque is so great it spins the wheels as soon as it accelerates. Easily as fast as an orange endbell Slot.it. The only reason I swapped arms is because in the turbo can it ran as slow as a RX-42 so I did some experimenting.

An easy way to get a quick SCX motor is to fit a Parma deathstar 16D armiture. They go straight in and run really hard with lots of power. Or you could fit a Group 20 arm and really have fun. Won't be drivable through corners but down the straight nothing will touch it.

I put one in my Red Bull Aston Martin certainly is a lot quicker - feels more like the Pro Porsche (same motor) but doesn't have very good brakes

any suggestions for how to improve the braking?

cheers

[munter]

Lower gearing will improve brakes but compromise top speed....best to adjust a crown wheel by a tooth or two but if you are using standard SCX rear axle;rims/crown then go for one tooth down on the pinion.
