KBDD’s newest product is The Tony Whiteside Extreme Edition upgrade kit for the 50 Nitro or 600 Electric size helicopters. The kit is commonly called the TWEE kit. The kit contains paddles, 92mm tail blades and 2 sets of dampers. The paddles and dampers are a totally new design and material composite. The 92mm tail blades are a new material composite. The paddles are even more stable than our existing paddles yet are quicker. They compare very well with paddles costing $60. The dampers are a one stage progressive damper which are soft around the middle yet get very hard during hard 3D. The 92mm tail blades are our previous design but with a new material composition which makes the stiffer than many carbon fiber yet are still more durable than carbon fiber. You can spend nearly $100 buying comparable products which may not perform as well.
