New Racing Engine Series – MkII

Dualsky has completely redesigned its GA engine series and is launching its Racing Series MkII, a thermally optimized version of the highly successful GA engine series. The open design allows for even greater power output thanks to improved cooling. This range of engines is capable of powering models in the 30 to 120 classes. By varying the stator sizes (4114, 6210, 6215, 6230), combined with the high pole count of 28, the series delivers specific RPMs tailored to each model class, featuring low internal resistance and high efficiency. The unique propeller mount with a lock nut based on the collet principle guarantees a permanently secure hold. The motors feature a temperature sensor mount, allowing optional constant monitoring of the motor’s temperature via telemetry. The motors weigh between 175 g and 600 g and are classified as lightweight, with a power output ranging from 800 W to 3500 W. Also included is a sturdy tail mounting bracket for easy installation directly on the firewall. The connection cables are equipped with gold-plated connectors. The following motors are available:

– LEO 4114/GA 800 with 530 KV, 640 KV, and 810 KV

– LEO 6210/GA 1500 with 245 KV, 490 KV, and 545
KV– LEO 6215/GA 2000 with 230 KV, 405 kV, and 465 kV–
LEO 6230/GA 3500 with 180 kV and 200 kV

We’d be happy to help you design the right drive system for your dream model according to your individual preferences.

Pilatus PC-6 Porter (1500 mm) by Kavan

The Swiss single-engine, multi-purpose STOL aircraft, the Pilatus PC-6 Porter, has been recreated by Kavan as a rugged RTF model.

The model’s fuselage is made of highly durable EPO foam (extruded polyolefin) with rigid internal carbon-fiber reinforcements. The C3548-750 brushless electric motor, paired with a 10x6-inch three-blade propeller and a KAVAN R-40SB ESC with a powerful BEC—required to power the six onboard servos—is mounted in the nose. In the nose, under the removable cover, you’ll find ample and easily accessible space for the flight battery (4S 2500–3500 mAh).

The model’s EPO foam wing consists of two sections with carbon fiber spars and a tubular carbon fiber connector. The wing is secured with screws. The ailerons and flaps are controlled independently by two servos each via short, straight linkages. There are also functional position lights and LED landing lights. The easily removable carbon-fiber wing struts are secured with wire clips.

The tail surfaces are also made of EPO foam. The rudder servo is located in the vertical stabilizer, and the elevator servo is in the fuselage. The control surfaces are operated by short, straight linkages.

The main landing gear is a fixed wire landing gear with spring-loaded scale struts. The wire tailwheel is connected to the rudder. You can purchase a float set as an option for the model—removing the wheel landing gear and installing the floats and water rudder is a breeze.

IBEX 115 HV Acro Controller

MAV Sense is expanding its wide range of speed controllers with the IBEX 115 HV Acro for use in glider or conventional acro models. With adequate cooling, the ESC is capable of continuously delivering 110 A (peak 170 A/2s) at 2–12s thanks to its heat sink. Thanks to its compact dimensions of 88 × 32 × 20 mm, the ESC fits even in tight spaces, weighing just 125 g. It features a powerful 15-A BEC (peak 30 A). Like all controllers in the IBEX family, the IBEX 115 HV Acro offers modern features: overcurrent and overheat protection; BEC voltage adjustable between 5.5 and 8.4 V in 0.1-V increments; configurable current limit, acceleration, and electromagnetic brake; support for common telemetry protocols (Duplex EX, Hott, MSB, PowerBox P2Bus, S.Bus2, SRXL2) for voltage, current, power, capacity, temperature, RPM, and energy; optional propeller positioning. The controller can be programmed via the transmitter, the MAV Manager PC software, or the Jeti or Smart-Box.
