Jim, the Tri-Track Product Page is saying that the Tri-Tracks speed is 24"/s. When I run my Tri-Track that I just got, I am getting about 8.5"/s on a fresh 3S Lipo.
I am using a RC control system, hooked up to a Sabertooth.
Do you know anything that could cause my speed to be a third of the advertised speed?
Thanks
You could jumper over the motor controller to the battery and see if the motors run at the desired speed. If they do, then there may be some issue with the motor controller or the control signal it is getting. If the motors turn slower, then check the voltage at the motor leads when the motors are turning to verify the voltage is at the rated value.
Hey Sienna, LTNS… I will have to look at it. It may be a value based on a 30:1 motor by mistake. Whatever the reason I will fix it.
Ok the OD of the driven sprocket is 2.75", the RPM of the 12vdc 50:1 motor is 120, so the calculated vehicle speed is. 17.3" per second. This is calculated from the no load RPM, so it’s going to run a little high. Calculating with the (12vdc, 30:1, 200RPM) motor gives a value of 28.9" per second, and with the (7.2vdc, 50:1, 175RPM) it’s 25.2" per second. So it looks like we forgot to update that spec when we changed the chassis to use the 12vdc 50:1 motor. Anyway I’ll update the website specs.
