VRC Column – Pan Cars & Data Logging

VRC Column - Pan Cars & Data Logging

The VRC development team is looking at pan chassis cars like the popular 1:12 scale cars to be added to the electric car selection. Although not finalized yet, 3D models have been created of the popular Associated 12R5 and 10R5 chassis to start testing with. The physics of these type of cars are quite different from the suspension cars and will require more research of VRC’s physics wiz Todd ‘Doc’ Wasson.

Data Logging with Novak Sentry System
Early January VRC conducted a series of tests with the NOVAK Sentry data acquisition (data logging) system to acquire actual in-car data of electric cars. The very compact and easy-to-fit Sentry system logs battery voltage, drawn amps, temperatures and longitudinal and lateral G (acceleration) forces. The tests were performed in close cooperation with electric sedan ace and Tamiya works racer Jilles Groskamp using the Tamiya chassis fitted with LRP Vector and Speed Passion brushless motors in different configurations.

Jilles will also conduct tests with the 12 scale pan CRC chassis to acquire data of this type of chassis too. The results give us actual data which will be used by Todd ‘Doc’ Wasson to fine tune the physics formulas and algorithms which he has developed for electric cars in the past 2 years. Such data was also available for 1:8 and 1:10 nitro cars and have proved to be essential and critical for the accuracy of the physics model that is used in VRC.
