Hi all, Just wondered if there's any way to tell the ohms on old scaley controllers from the 1970's. I've got a few of varying colours and there does seem to be some difference between their power. Thanks

Hi,
That throttle was first released in 1968 & was available in various colours over the years.
They were a standard 35 ohm resistance.
I still use them on my old layout. They`re a lot better than the modern throttles.
Variations in performance could just be down to age & ammount of use.

There was a very large batch of throttles sold circa mid 1970s which are potentially dangerous as they have the heat shield missing. If you have blue or yellow throttles from that period look through the top vents to check the shield is there.....if not, chuck it....

(between 1966 & 1972 there was a larger, black race tuned throttle, available in either 15 or 25 ohm)

Cheers,
Kev.

Or you could take a multimeter, set it on a suitable ohms range (on most meters that'll be 0-200 ohms range) and measure the resistance.
(Don't be surprised if the actual resistance is 20 or 30% away from the numbers Kev quotes, there's quite a big tolerance on most manufacturer's quoted values.)
