It was sold as a direct replacement for the GWS Dragonfly's swash, which of course it isn't. The Dragonfly, like most other FP helis on the market, uses 3mm balls on the swash and fly bar control paddle, however this one was supplied with 3.8mm balls. Problem solved replace the balls... not possible, no longer manufactured. So Nikki from heli hobby tracked me down and shipped me some 3mm balls. However I've since moved on, and there is since a much better mouse trap.
Enter Xtreme, with their lovely Swash, Paddle & Blade grip.
