Yeah, I did. The way they wrote it implied it was for air ESC's only. Glad to see it works for surface speedos aswell.


I tried out running boost/turbo during a practice session one day and you know what it got me?

Absolutely nothing. The motor didn't magically turn into a 70,000 rpm mod monster; never got more than a 20th of a second faster; never shot out of the corners like a scared cat. It just ran into its own designed-in limitations like a drunk guy walking into a hotel wall.

Boost/turbo only works in mod. So the guys thinking they'll get some sort of advantage in stock if they surreptitiously turned it in would gain absolutely squat, except a cooked motor or speedo.

yeah always check your rules. I race here in southern California and i only race at local club races. Generally the places i race at only care if your running the correct 17.5 motor or a 21.5 motor and the esc is in blinky mode. They dont really care about all the other offical ROAR rules like only minimum weights / telemetry must being off/ only charging to 8.44volts and all the other many roar rules.

You weren't using it properly then. Boost/turbo when used right will make a car significantly faster while making the motor run cooler.

I tried every single combination I could think of. high timing on the motor, low boost timing. Low mechanical timing, high boost timing. low mechanical timing, low boost/low turbo, and everything in between. Up on the pinion, down on the pinion. I still ran into watt limits of the motor. 21.5's can only do so much. It was a good learning experience nonetheless.

Did you change spur? Because you generally need vastly different gearing when using boost/turbo that a simple pinion change usually isn't enough.

There is a (not very widely adopted) class in Asia that is specifically catering for "time limit activation boost" (or something like that). Via an extra channel on the receiver, the ESC firmware will apply a different timing profile for a predetermined time period (usually a few seconds) for a limited number of times (say 3) during a single run. I've raced this as a demonstration class and there is a *significant* difference in performance. You get regular blinky ESC profile for the bulk of the race and at you discretion, trigger the boost via a button on the radio. It is quite unsettling if you're in a groove, but is also a lot of fun.Using it to blast past another car at the right time is a hoot. This event used a standardised motor/ESC combo that supports the function and just needs a third channel on the radio to activate.
