What is Spec Racing?

Due to the extremly high speed of open class FPV racing it is very common that spectators, sometimes even the pilots themselves, loose situational awareness during the race and don`t know the ranking until the race is finished. With Spec racing we try to virtually slow down the race pace, so you see the competition taking place on the race course, as pilots fight for position based on skill alone.

The portion of competition that happens off-track is largely invisible to those watching the race. While spec isn’t truly more competitive, it appears more competitive to the spectator so it is more exciting to watch. Exciting neck-and-neck battles become more common when the quads are more evenly matched. This is a huge advantage of spec racing as a spectator, as a pilot, and even as an organizer. It’s one important reason why we started pushing spec racing.

Spec racing will always be behind and, yes, at least bit slower. Often, the spec class is intentionally much slower. Even Formula 1 cars, the pinnacle of auto racing, are limited from reaching their true speed potential. The fastest recorded speed in a Formula One race is 231mph, but there are production road cars that can top 300. Racing has never really been about speed, but is actually about making the best of your time while working within a given set of constraints. A performance limit is precisely what makes Spec racing more competitive on instead of off the race course.

How does it work?
You can join with any 3-5 inch analogue fpv drone you own. Before the race we measure the weight of your drone, prop size, motor size and Lipo cells. With all those values accounted for, the calculator gives a certain amount of throttle cut value for betaflight (scale) and puts every drone on a 3S 5inch level.

Example for a normal race drone today:

  • 507g weight
  • 6S
  • 5inch props
  • 5.1 prop diameter
  • 4.6 prop Pitch
  • 2080kv motors

⇒ 46% throttle cut

Here you can see a screenshot of the Betaflight Rates tab, where you need to setup your throttle cap.

Change the Throttle Limit type to SCALE and the Throttle Limit percantage to the exact number you calculated in the »»Spec calculator before.
