Roche P12V2 First Race - Lower grip Asphalt
Speedy RC Queensland State Championship
Following a break of about 7 months, I raced the freshly built Roche P12V2 last weekend at the Queensland State Championship.
I found good pace for the A3 deciding final between myself and TQ driver and current National Champ, Michael Stone. I lead the whole race but choked and clipped a marker with only two corners remaining. Congratulations to Mick and all the drivers for the close fun racing.
Thank you to Roche-Team Powers Japan member- Shota Watanabe for a few initial suggestions and especially to Paul Sims at Bezerk RC.
The (Bezerk) custom machined battery tray allowed for an extra 0.5mm of raised main chassis clearance. This was tested to suit the large bumpy track which included many reflector markers and a few plough discs. The Bezerk 2.5mm carbon main chassis plate is a standard type weave.
This should be a great start for outdoor asphalt tracks. Just change to around 2mm-1mm pod droop. If using a standard chassis then subtract 0.5mm from the front ride height balance.
V5S Actinium was spaced 1.5mm for stability on the bumpy high speed flat sweeper. (anti-clockwise) There was also 5g on the left front arm. AMR 0.7mm body mounted 2-3mm forward and high rear rake.
Smooth tracks can easily be set with a lower ride heights depending on tyre wear.
The Team Powers Electronics setup was faultless all weekend. After a chat with Norwegian National Champion, I guesstimated the gearing and Actiinium V5S.timing for a broad power torque tune at 20 on the can. I turned it up to 25 for A3 and rollout practically remained unchanged since Q3 at 99mm. The ESC tune was relatively conservative at 8K and modified mode ( blinky zero timing) for the smoother overall throttle profile. Everything stayed cool all weekend and end voltage of the EZpower 8600 1s was around 3.85v.
Thank you Speedy RC and Roche. I shall also be racing the new Destiny DTY12S.
