The G-21 series has to be one of (if not the most) sucessful engine familes ever produced. Through FRV & RV versions and displacements of 29, 35, 40, & 46 ALL made their marks in Speed, Combat, Racing, Carrier, & CLPA, not to mention their impact in RC Pylon & Free Flight.
Thank You Jaures and SuperTigre for a job well done.
