New Spec Class Racing Comes To Music City


This will be Music City Multirotors first attempt at organizing a spec class drone race.  The hopes are to bring in new pilots that are unsure of exactly what they need to get started.  Spec racing eliminates a lot of the hassle that goes along with designing and building a copter for racing.  With everyone running the same equipment it should be easy for beginners to get help,  the specs were selected based on a number of factors including price,  build time,  build difficulty,  performance,  and availability.

There is a kit available on banggood that has everything you need except the FPV gear and R/C control that is appropriate for most people.

The rules are as follows but are subject to change:

Mandatory Specs


Realacc X210 214mm (4mm VERSION ONLY!) Carbon Fiber FPV Racing Frame

 The frame must be unmodifed and in its original intended state.

You can also use the original frame from Lumenier


Racerstar Racing Edition 2205 BR2205 2300KV 2-4S Brushless Motor

These motors are available in other colors just make sure the specs are correct.

4 in 1 version of racestar or cicada is allowed 20a


Flight Controller:

Can be any F1 or F3 generation flight controller.  F4 generation flight controllers are NOT allowed.




Any 4s lipo is permitted,  there is a voltage limitation rule set a 4.20v max per cell.  So you CAN run lihv but it must only be charged to a normal voltage of 4.20v like a standard lipo.



PDB,  FPV Gear and R/C control:

200mw VTX max with Raceband.  

We recommend everyone start buying switchable power output VTxs as we may be running races on 25mw next year.
