The RX72N HYBRID, with Built-In Speed Controller
and Dial Up Throttle Cut Down Point by, SKY HOOKS & RIGGING

NEW NARROW BAND HYBRID SUB-MICRO RECEIVER
FROM SKY HOOKS & RIGGING
The new RX72N-HYB, 5.5 gram, sub micro receiver, from Sky Hooks & Rigging, is lighter than other narrow band receivers without speed controllers. This unit also incorporates a number of other features not found in the other receivers. Now you can go outdoors to the park, with other flyers, and not worry about being glitched unless someone else is on the same frequency you are using. This thing has single channel discrimination.
The speed controller is built in and has a BEC, soft start, and 7 Amp continuous capability. The controller does not chop the throttle, but drops high throttle to one-quarter so that you can still land your airplane if you are driving a slow flyer. You no longer need to worry about whether or not you will destroy your lithium polymer cells;...the throttle cut-down Voltage is selectable to several preset Voltages. The system is capable of providing throttle cut-down at 6 V. used by some for two lithium polymer cells (POLYCELLs), 5.1 V. for NiCd batteries or NiMH cells, 9 V. for 3 POLYCELLs, and 12 Volts for 4 POLYCELL operation. You can also turn OFF the throttle cut-down, in case you want to fly four to five volts without worrying that your plane will shut down ahead of schedule. The speed controller runs at 4 kHz. This should help to save some brushes as it is a higher frequency than can be found in most available speed controllers. Only the little 1.5 Amp HF-100 controller, by JMP could be found with a higher frequency.
The RX72N-HYB does not care whether you are using Futaba, Hitec or JR, or where the throttle is in the pulse stream. The guys at the Sky Hooks lab have designed the receiver to read the incoming signal to determine which brand of transmitter you are using and where the throttle should be. If you want to change your transmitter, just do so. Also, changing channels is simply a matter of getting the appropriate crystal from Sky Hooks & Rigging and plugging it into the receiver’s crystal socket. This thing is really a no muss, no fuss machine that will stand out in front of other receivers.
Like all Sky Hooks & Rigging receivers, the RX72N-HYB is tested to 1,000 feet. Although the actual airborn range is much greater than that, we only test to 1,000 feet on the ground because it is not possible to see a small aircraft comfortably at greater distance.
The RX72N-HYB has the following characteristics:
72 MHz, FM fully proportional
Single channel discrimination
Built-In Electronic Speed Controller selectable throttle cut-down points.
Servo channel functions (3 servos plus one dedicated speed controller) 4
Available frequency channels for 72 MHz 11 through 60

Dimensions 1” x 1” x 0.375”
Range 1,000 feet
Current Draw 10 mA @ 5 Volts
Operating temperature range 0°C to 70°C
Input Voltage Range 15 Volts
RF Input Bandwidth ±10 KHz
Transmitter Compatibility JR, Hitec, and Futaba
N-HYB Speed Controller Characteristics:
Features:
4 MHz RISC Microprocessor
Safe - Switch-On. Waits for Low Throttle before starting.
Soft Start
LED used as throttle indicator.
Fast throttle response.
Motor stops on loss of signal
Motor restarts on signal reacquisition.
The RX72N-HYB ESC does not shut off power to the motor, when the battery Voltage drops below a predetermined Voltage, but reduces the amount of full throttle available to a maximum of one-quarter-throttle.
You may program he RX72N-HYB ESC to cut down the throttle at any one of the following Voltages, using the ESC Cut-Off Setting Switch:
5.1 V., 6.0 V., 7.2 V., and 9.7 V.
You may also turn off the throttle cut-down by selecting 0 on the switch. With 0 selected, the BEC still operates, but the throttle will not cut-down. The ESC Cut-Down Setting Switch is a rotary switch with five preset positions for the cut-down point for the throttle.
Control range: 1.2 ms to 1.8 ms
Valid pulse range: 0.8 ms to 2.4 ms
Nominal voltage: 6 to 10.5 V (15 V absolute max.)
Current: 7 Amp continuous, 9 Amp max.
BEC: 0 V., 5.1 V., 6.0 V., 7.2 V., or 9.7 V. selectable, max. 0.8 A
Modulation frequency: 3 kHz

The RX72N HYBRID-V, Specially Designed for Low Voltage Operation (3 Volts)
with Built-In Speed Controller and Automatic Cut Down Point for Lithium Ion and Polymer Cells, by SKY HOOKS & RIGGING

NEW NARROW BAND HYBRID, LOW VOLTAGE, SUB-MICRO RECEIVER
FROM SKY HOOKS & RIGGING
This new unit is designed to operate on a single, 3.7 Volt Lithum Ion or Lithium Polymer Cell. Its operating Voltage range is between 3 V. and 5.1Volts. The user should not attempt to operate this new Low Voltage receiver on higher Voltages than 3.7 Volts nominal.

NEW
The POLY PACK Single Cell Solution, by SKY HOOKS & RIGGING

The RX72N-HYB-V Low Voltage Receiver
450 mAh Lithium Ion cell
Lithium Ion Charger, from JMP of France
IN ONE MATCHED, ECONOMICAL PACKAGE
Designed for models weighing between 50 and 80 grams, that fly like rubber powered airplanes, but are electric powered and radio controlled.
We have flown this system using KP00 or our own SHP-1 geared drives, from 5:1 up to 8:1 ratios with 5" to 8" props. The aircraft had wingspans from 20" to 30 " and wing areas from 150 sq. in. to 300 sq. in. The servos we recommend are HS-50, by Hitec, or PICO BB, by GWS.
THE RECEIVER is identical to that shown in the article above, RX72N-HYB-V. It is designed to cut the throttle to 1/4 when the power in the battery drops as low as 3.0Volts. The maximum operating Voltage for this unit is 5.1 Volts. This receiver will operate on a 3-cell NiCd pack as well, but should never be run using a 4-cell pack.
THE POLYCELL-200 is 3.7 Volts nominal. When fully charged, it has a top Voltage of 4.2 Volts. This is ample for the operation of the recommended motors. The cell weighs 5.2 grams and has a cut-off point of 3.0 Volts. Should the Voltage in the cell be permitted to drop below 3.0 Volts, the cell will go into a coma and never return. The dimensions of the cell are 30mm x 17mm x 6.4mm and its capacity is 200 mAh. The cell has a discharge rate of 1.5 Amps and a charge rate of 100 mAh.
THE CHARGER has been specially designed for the purpose of charging POLYCELLs. The charger requires a 5-6 Volt DC source, such as a wall adapter.
All of the components for this Solution are priced individually, elsewhere in this web site:
RX72N-HYB-V Low Voltage Receiver
POLYCELL-210 and Other Polycells
CHG-POLY charger for single cell applications
The characterisics and specifications for the low Voltage receiver are the same as for the RX72N-HYB, with the exception of those characteristics mentioned here. The operating Voltages are from 3.0 V. to 5.1 V. and the throttle cut down for the 7 Amp speed controller is at 3.0 V.
