I’ve noticed that many of the Rockets use different empennage kits. Why?
Originally, the RV-4 tail was the standard recommendation for the HR2. Lately, several builders have opted for the RV-8 empennage since it has a balanced rudder, which supposedly would be more flutter resistant, and the increased area of the -8 vertical surface offers more stability. The -8 elevators are on the small side for Rocket applications (not quite enough authority in the flare at fwd CG/full flap situations), but the -4 horizontal surfaces work fine. Team Rocket now has an F1 specific-designed empennage kit, also pre-punched in many areas. The vertical surface is enlarged over the -4 surfaces, and the rudder is counterweighted. The elevators have faired counterweights, and are sized to accommodate the wide CG range of the F1 (and the HR2).
