The O.S. Speed B21 Ronda Drake .21 Pink Edition Engine was developed using the Adam Drake engine specs, and given a pink livery update. Plus, these engines have been broken in by Adam Drake himself using Adam's "EBIS" engine break in services! Now, the same "Oil Bath" break in service trusted by Ty Tessmann, Ryan Maifield, Robert Battle, Spencer Rivkin, Mike Truhe, and many others is now available to you, performed with the knowledge and precision that has made The Drake a legend in RC racing.  

Finished in Ronda Drake's signature pink color scheme applied to the cooling head and carburetor restrictors. This engine features the same bore and stroke, double counterweight embedded crankshaft with DLC coating, ceramic rear ball bearing and O-ringed inner head as the O.S. Speed Adam Drake engine. With all these features this is truly a race proven machine.
