Servo Extension by JR

Available in the following lengths:

TNC Tachometer by Fromeco

The best Tach on the market - bar none!  Stand back several feet and safely take your reading of the 5 digit display.

High quality optical sensor locks on in various lighting condition from about 5 feet away. Available Store Direct - Worth the price.

Optical Kill Switch

These quality optically isolated electronic kill switches allow you to kill your engine from a spare channel on your radio should your throttle servo malfunction.  What would you do if you started your engine and the throttle servo was at full power instead of idle because the servo malfunctioned?
It just recently happened at our field on a 40% 42 pound engine that produces about 17 horsepower swinging a 32" prop.  - With an E switch it is a simple matter of hitting a switch and killing the engine.  What would you do if this type of failure occurred to you?  Would you have been hurt because your 40% plane ran into you at full power?
Specify Electronic or Magneto.

Charge Receptacle

It is important to keep dirt out of your switch system. When using a switch with no dust cap this  machined charge recepticle by Madison is universal and fits all brands of radios charge harnesses. Keeps dust and dirt out with a twist on cap.

Jomar Battery Backup

Functions with JR, Futaba, and AIR. Wired.

Jomar Servo Reversers

Servo Reverser and/or Exponential digital device provides servo reversing or exponential control or a combination of both for one channel. Size .5 x 1 x .27, weight 2 ounces.

Jomar Y-Harness with Reverser

Works with radios on 4 or 5 cells. Install in line with any servo and the servo will move in the opposite direction! .5 x 1.75 x .25 - weight .25 ounce!

Jomar Glow Driver

Glow drivers are used to provide power to the glow plug below selected throttle settings. This glow heat reduces the likelihood that the engine will die at idle or low power settings.

Jomar Sequencing Gear Doors

Gear servo and door servo travel time individually adjustable from full speed to 10 seconds. Gear doors may remain open ala P-47 or close after lowering gear ala P-51.

McDaniel Glow Driver - Single

Glow drivers are used to provide power to the glow plug below selected throttle settings. This glow heat reduces the likelihood that the engine will die at idle or low power settings.

Jaiccio Regulators & Switches

Jom Odinno - former 35 year columnist for RCM and the O of S&O Proportional radios,  developed this regulator years ago for high performance IMAC-Giant Scale and Pattern  planes. It weighs about 1/2 oz, is set to either 6 volts or 5.1 volts, and is used  on our 42% planes. Input voltage up to 15V and output current up to 5 amps. (A 42% plane with 13 digital servos will draw about 2.8 amps average if the plane is set up correctly.)

Regulator only - 5.1 or 6V.

Regulator & Switch.

Safety Clips by JR

Used to secure extension cords, battery, and switch leads.

Heavy Duty Servo Wire

Genuine JR 22 heavy gauge low resistance wire is perfect for those long extension cords needed to reach the tail or servos on wings.  Perfect when used with the CEL connectors.

Sold by the foot.

Self Adjusting Bellcrank and Servo Tray by SWB

The SWB self adjusting bellcrank and servo tray is a breakthrough in pull-pull system design. The cable system eliminates the need for matchboxes and the need to perfectly match the servos. No binding and if a servo fails, the remaining servos continue to operate the system. All hardware and bellcrank is included and the tray comes in either 2 or 3 servo configurations fitting JR, Hi-Tec or Futaba standard size servos.

Assembly is required, specify servos to be used. Servos not included.

Half Arms 1" Double Lock

3D 1 1/4" Half Double Lock

3D Full Double Lock

3D 1 1/2" Double Lock Arms

Bellcranks

Bellcranks are CNC cut aluminum and come in a variety of sizes. They are used in pull-pull systems for large aircraft to keep the tension off the servo output shaft. Additionally, bellcranks keep the line tension from compressing the servo rubber grommets due to cable compression resulting in what many perceive as cable stretch. The servo pushrods are attached to the bellcrank and 2 cables to the control surface. Bellcrank allows tightening of the cables without loading the servos.

180° or Offset Bellcranks - 3", 4" or 5"

Servo Trays by SWB

These trays with built in bellcrank come in 2, 3, and 4 servo configurations and are sized to fit standard case size servos such as the JR 8411DS or equivalent Hitec or Futaba servos.

25%-35% - 2 Tray: Typically used for IMAC-3D type flying.

35%-40% - 3 Tray

40%+ - 4 Tray: Typically used for 3D type flying.

We can help you select the correct tray.
