Rapid progress in electric model power technology now allows us to offer the Rafale in a version with retractable undercarriage. In this form it is now capable of ground take-off from level, closely mown grass strips as well as from hard surfaces. The net result with this twin-engined aircraft is much greater scale fidelity both on the ground and in the air. A matching 3-part pneumatic retractable undercarriage with steerable nose wheel is available as an accessory set. The update is completed by a new fuselage, molded in Kevlar fiber for extremely low weight (Kevlar kit) or molded in fiberglass (FG kit); it offers maximum strength and contributes to the Rafale’s phenomenal flight performance. All formers required for the retract system installation are pre-cut using CAD data, and are supplied in the set.
The key factor in making this new version feasible is a completely new power system concept. The previous system consisted of two relatively small ducted fans, which are now replaced by a single, highly efficient 120 mm impeller unit. This all-carbon electric fan is a completely new development, and generates up to 40 N static thrust with a suitable motor. The single motor and fan mean that the overall cost is lower than the previous arrangement, even when power system components of the highest possible quality are employed.
With the recommended Plettenberg HP370/40/A1 motor thrust of over 45N can be expected with over 2kW input. As was the case with the original twin-fan Rafale, the two-part fuselage makes it easy to install and maintain the impeller system. The kit includes finished, accurately made FG bifurcated pipes of refined aerodynamic form which are responsible for the efficient flow of air from the intakes to the fan unit, and from the fan to the divided efflux.
