If you look up this Heli RTF: "Venom Air Corps Night Ranger 3D" it comes with 6Ch Tx for £179.99. Could this radio be used for ekectric park flyers? If so, you could buy the Heli, and with the addition of another receiver, servos, ESC etc, you could have 6Ch Park Flyer? Is it the range or what that would make this unsuitable for small electric aircraft?
