Last night (Thursday) was the turn of the Tottenham class of sports based on chassis and motors from late '60s-early '70s at Raceway 81.

There are a set of rules for you to see on the website under UKRRA. Basically any motor raced in the period up to 1972, C-cans of any make without cut-outs around the endbel, . any ceramic magnets over 0.500" long, any endbell and hardware except alloy endbells. Armatures must have min diameter of 0.500" and stack length of 0.440" minimum.

It was a hard night's racing, with eleven members in attendance. These chassis have all been built in the last 12-18 months.





The B final.



The A final.



Winning car, 30 turns 26 guage, Koford magnets, 7/40 gearing.

Mike,

Good stuff and I really like the guide flag lead wire clips in the last picture.

[Mark Johnson]

The braid clips are SCD made by Chas Keeling. he's been a supplier in the UK since the early 60's.

It's a version of one of your chassis from the independant scratchbuilder web site, I had to fit a straight axle, runs very well on our track with hard tires fitted for the race, top qualified too.

Quality line up must build me one of them.

Mike, just curious, how sticky is the track you ran that iso on. The design was originally designed to combat tons of brown stick it in the full glue days. I never tried one in limited or retro style track conditions. Very nice job on the chassis.

Way more vintage than our current series over here. Way to go!

The track grip was inconsistant, slippery at times I was using JK wonder. Wheelspin off the line, but superb through the esses and dounut, We used to run 1/32 with full goop and it's not like that, the track has not been cleaned in a few weeks but we only use it twice a week. temperatures are low about 4 degrees C outside and the track room is about 15 degrees and never really warms up in the winter. I am able to power round with visible drifting, feels very good to drive. I also have a Emmot style drop arm chassis with a Group 20 in and was going to run that but it lost power, that also is very smooth with the lesser powered motor about 0.2 sec slower per lap. the track is flat apart from the banking.

Wow, wonder rubber. Would never guess that that chassis would have enough bite. Cool. Sounds like fun.
