Easter Track Recap & Tuning…. (Ka500 & MiniCoop)

This Easter weekend has brought us more sunshine than expected and we took advantage of every ray with long sessions at the track. This morning, for instance, the MiniCoop set a new lap record of:

  • 29.028 seconds – Driver Astoria – Dry Track

(we mean a TeamVebra only Record, of course :) ) The track was nice and dry but cold at around 8 or 9 degrees Celsius, it always took us a couple of laps to keep the tyres in check. It proved a very pleasant and successful session with quite a few “lessons learnt”.

For instance, whilst at the track:

  • We tried 1/10 Touring Racing Slicks on the Ka500 with rather dubious results. It might have given it a slightly higher top speed but it also raised its centre of gravity and made it handle a little worse in the steep corners. More importantly, they looked too big on the M03m
  • We moved the Receiver further away from the Brushless-Esc (on the MiniCoop) as we’d noticed some strange interference (at very random times) and, once we moved it, it behaved normally again.
  • We moved the Brushless-Esc a little as well to try and have a better angle for the Motor wires. I don’t think we can say we noticed any difference but it was after that small change that we got a new PB… so perhaps it did … :)
  • Changed the settings of our Brushless Etronix Photon Esc via its very user friendly,  if a tad obscure, programming card 
    • Set the ‘Start Power‘ to High (from Med)
    • Set the ‘Drag Brake‘ to Low (from Med)
    • Set the ‘Settings‘ to “manual” (having no idea of what difference this might make!)

Once back in our TeamVebra StudioLab  we also:

  • Fitted a replacement Futaba S3003 Servo on the Ka500, and re-adjusted the Turnbuckle tie-rods. As mentioned in previous posts, the steering was way off.
  • Fitted the HPI Firebolt 15T on the Ka500 instead of the Ansmann Clash15T
  • Changed the Pistons of the Aluminium  oil dampers from the 1-hole type (too slow) to the 2-hole type. We also added 3 additional O-Rings in the Piston shaft to shorten the pistons’ travel and make them more appropriate for a low M03 chassis.

  • Swapped the Right-Hand-Side tyres with the Left-Hand-Side tyres on the MiniCoop. At the moment all 4 tyres are Shimizu-Medium. We noticed that due to the fact that the track is counter-clockwise, the tyres on the right hand side (the “outside tyres” on most corners) were wearing down more rapidly than their left counterparts.

We’ve still got some work to do on the Videos that we took this morning and, very exciting, a new section of our Website should soon be up to report our Lap Times and Car’s Specs… so stay tuned to vebra.lu for more RC GEEK STUFF !
