A semi scale model of the American aerobatic aeroplane for 30-40ccm petrol engine or 3-4 kW brushless electric motor for experienced pilots capable of the classic pattern as well as extreme 3D style.
The fuselage is of - now classic - ultra light design featuring balsa and plywood Kevlar®/carbon composite reinforced parts, detachable fibreglass cowl and large fuselage/canopy hatch allowing perfect access to the entire power system and RC gear. The engine or motor is to be fitted to a plywood/composite reinforced box using a radial mount.
The two-piece all-balsa wing with a symmetrical airfoil uses a carbon tube joiner; the wing halves are secured with screws to the fuselage. The large ailerons are controlled by a single servo each. You can install the supplied SFG winglets to the wing tips.
The empennage is a light all-balsa work; the horizontal tailplane is a single-piece, glued into the fuselage. The elevator and rudder are controlled by servos installed in the tail part of the fuselage.
The entire model is covered by the ULTRACOTE® iron-on film (ULTRACOTE® is the trade mark for the ORACOVER® film used in the USA.)
The main undercarriage features carbon composite legs, fibreglass spats and lightweight wheels; the tail wheel with a carbon bracket is coupled with the rudder.
You will need a reliable 30-40 ccm petrol engine or at least 3 kW brushless electric motor, at least 100 A ESC and 40C 4,000-5,000 mAh 8-12S LiPo pack.
You will need at least 6-channel RC set to control your Edge 540 - the precise set-up of servos, optimized dual and exponential rates is the must for aerobatic flying - the pattern as well as extreme 3D.
You will need 5-6 fast and strong standard size digital servos, like Hitec HS-7955TG, D954SW.
