The RX72 HYBRID with Built-In Speed Controller by SKY HOOKS & RIGGING

The WORLD'S LIGHTEST and smallest, 4 channel, fully proportional FM receiver, with a built-in, 7 Amp, BEC speed controller, at 3.3 grams as shown, or 2.9 g. without the shrink tubing. Cur off Voltage for the ESC is 5.1 V. The BEC does not cut throttle completely, but drops the available high throttle to 1/4. This promotes a landing withoiut the often fatal zero throttle that can be so difficult for slow flyers.

Still lighter than the regular RX72-JST receiver and speed controller combined. Even lighter when you consider that there are no connecting wires and plugs between the receiver and the speed controller.

Other HYBRID Receivers for Special Appications such as low voltage and POLYCELLs

At 3.3 g. , this 4 channel, FM, 72 MHz receiver is perfect for indoor and back yard R/C. The RX72-HYBRID is available on any channel from 11 through 60. These receivers are in stock. Compatible with PPM transmitters: HiTech Focus-4 or higher, Futaba, JR, and Airtronics and Multiplex. Size 0.0938" long x 0.75" wide x 0.25" thick. Single sttick transmitters may have compatibility problens due to an unusual location of the throttle in the pulse stream.

Other Models of RX72 Receivers Available

Click Here For RX72-JST, 2.8 g.

Specially designed for indoor radio controlled flying, the RX72, with JST connectors is ideal. The sockets match the super light WES Technik linear servos. Weighing in at 2.8 g, (with servo pins, shrink tube and antenna) this little gem is a 4-channel receiver. Special servo adaptor plugs are included with the receiver, for those who wish to adapt standard servos.

Click Here For RX72-PRO, 1.9 g.

The RX72-PRO is for the purist, looking for extreme lightness and is available without the JST connector sockets. Instead, solder terminals are provided to allow direct connection to servos and speed control. Model RX72-PRO is a 5-channel receiver, its weight is approximately 2.0 g. (with wires, shrink tube and antenna) and its dimensions are 0.8" x 0.525" x 0.3". Otherwise the PRO has similar specifications to the RX72. The RX72-PRO is ideal for helicopter work.

These units are regularly in stock. The retail price of the JST, F, and PRO models of the RX72 is $110.00 in U.S. Dollars, or $145.00 CAD equivalent.
