Small footprint speedo
 

Does anyone know what brushless sensored speedo has the smallest footprint?

I'm thinking it may be the Tekin RS series unless anyone can think of another manufacturer?

It doesn't have to be high power as its for vintage racing with a 10.5 but I would like it to be quite cheap.. :)

The Speedpassion Reventon-S can handle up to 9.5T (according to Schumacher website) and is quite cheap and quite small:

33mm X 33mm X 19mm

Tekin RS is about 30mm x 30mm x 10mm high (plus a little bit more height for post/wire joints), the RS pro being a bit higher with its extra bank of fets. I run my RS in my GT12 car, with 13.5, but its perfect in my 2wd buggy with a 10.5 also. They will run to 7.5 I think limit, so fine for your vintage car I'd have thought.
I've not observed anything smaller, but that's not to say something smaller doesn't exist?

If you want really small, go brushed and a Tekin FX-pro

just found this one as well:

Dualsky XC550-TF-MJ 65Amp

http://www.ebay.co.uk/itm/Dualsky-XC...124693a&_uhb=1

Dimensions(LxWxH):34.5 x 33 x 21.0mm

not had any experience of these though so not sure what they are like.

Yes I'd typed that, but deleted as the op said brushless the only ;-) I'd run my FX-R and a 15 tripple or my old losi 16 quin. I really must attend some vintage races.

In a word, Awesome.
I have the 850 and a 800 model of the dualsky Speedos and brilliant. Very very happy with mine and with the usb programming dongle the tuning is excellent.
I know one guy who the 550 and is very impressed with it while using a 6.5 turn motor on it.

The Viper speed controls are also small, same size or slightly smaller than the tekins rs

Only problem with the Viper kit is that no one is importing or supporting them in the UK at the mo, which is a real shame as they seem good pieces of kit, but you really need to make sure you use firmware A30 or A55 as well or you may have issues with thermalling motor/esc.

Another vote here for the dualsky, amazing piece of kit

Im really temped with the £65 Dualsky - I notice that it is rated down to a 6.5T. Out of interest, how well does it handle a 6.5t in a 2wd buggy? any overheating/cutout issues when advancing the timing?
