Another lovely day at the Cotswold track today… my neck is nice and pink to prove it!
In 13.5 touring my main aim for the day was to find a good ESC setup. I use Hobbywing technology with a Much-More sticker on the side and a Speed Passion v3 motor. I’ve been unhappy with the low-end feel of both the 518_stock and 119_stock firmwares, so I decided to start afresh with the latest 211_stock.
After a long practice session I made a small breakthrough. Too much boost timing seems to bog the car down badly. Running at 36 steps with the motor on +10 mechanical timing resulted in ballistic speed throughout the rev range.
These are the settings I was using in the end (indicated by “+”). The car was as fast as anything else on the track today, although motor temps were close to the limit. Gear ratio was 7.3:1.
Unfortunately my racing was cut short by a silly driver error (watching the lapped traffic not my own car) which saw me flip into the grass at high speed and break the rear shock tower mount – again.
Mini class was a real pleasure. Although there were only three entrants this time (would love to see a full heat), I had some super-close battles with John Timberlake’s 4wd car. He had a couple of tenths per lap on me in qualifying and the first final, but in the second final I seemed to have regained a bit of top speed while John lost a little grip, and I managed to sneak ahead of him for the win. A little rubbing, but nothing unfair, and great racing. We had both knocked almost a second from our best laptimes at the first round.
I’ve made a few changes to the front of the Xevo in an attempt to keep the rear end more planted (ackermann and bump stops mainly), and they seem to have worked. The car has been super stable indoors and out for the last couple of race meetings.
Here is the setup for the tarmac track. On carpet my only changes are to the gear ratio (20T pinion), front tyres (Sweep 25 with glued sidewalls) and additive (Nosram carpet).
