Although you can use this mount to put the servos anywhere along the boom, we've found a great enhancement putting the servos right back at the tail and using the stock music wire for short pushrod wires. You'll get rid of pushrod wire weight but the real advantage is your eliminate tons of pushrod flex, your controls will tighten up and you'll find she handles a little more solid in a breeze.

Kit allows use of different size servos. I like 6 gram servos like Pico's and HS-55's on my sticks. You might think moving the servos back would cause your stick to become tail heavy but remember your eliminating pushrod weight and what your moving back wasn't up front, it was already somewhat to the rear already. We find it works out just fine and the model is still easily balanced.

39" (1 meter) Airtronics Old Style / Sanwa servo extension harness, 22 ga. wire.

Talon HV 120 is the first high voltage controller to come out of the Castle factory with a built-in BEC. This powerhouse features a 20A peak BEC with selectable 6v or 8v output voltage. With a voltage input range from 3S to 12S LiPo, and a 120A continuous amperage capability, it's capable of up to 6000W of continuous power for a wide variety of heli and fixed wing applications. The sleek aluminum case keeps the ESC cool during high power demand situations. For set-ups with limited airflow, such as under canopies or in a fuselage, there is an optional 40mm fan (sold separately; operates at 4.8 - 7.4 volts). Talon HV 120 has access to Castle's industry leading software functions, and USB programming capability via Castle Link USB Adapter. *Remove BEC Power wire from receiver before connecting to Castle Link.

The Talon ESCs are programmed to sound a number of tunes and codes using the motor as well as flashing LED patterns to alert users to certain conditions regarding their power system, such as over temperature, excessive load and locked head speed.

Telemetry Capable

Telemetry has the potential not only to improve the safety of our models by monitoring battery voltages, ESC temperature, and other critical parameters, but it also creates other opportunities to get even more fun out of flying because you've essentially reduced the risks of "unknown" inevitable crashes. Think of the benefits to be had from alarms that will sound to warn you when there's interference about or if your receiver battery is running unexpectedly low. Requires purchase of Castle Telemetry Link for S.BUS2 (Item # 010-0152-00) and compatible Futaba Radio or Castle Telemetry Link for X-BUS (Item# 010-0148-00) and a compatible Spektrum Radio.

Warranty

Coupled with our unparalleled 1-year warranty and world-famous technical support, Castle provides confidence and peace of mind that your Talon 120 HV is a smart investment. In this day of "throw-away" electronics, put your investment in a trusted name with a proven track record of support and service.

Talon HV User Guide Talon HV BEC Wire Warning

*RC HOBBY APPLICATION RATING: 120 amps for the duration of a single 10,000 mAh battery pack with the ESC in contact with a 5 mph airflow of 25?C (77?F) or cooler air. Controller temperature must never exceed 100?C (212?F). Exceeding current or temperature ratings may damage components and may shorten the life of the ESC. Always verify system current draw at full-throttle. Decrease load or increase airflow to decrease the ESC's operating temperature.

**Peak indicates amperage sustainable for 0.5 seconds - long enough for most servos' current draw transients. Always confirm servo current draw before the first flight of the model.

Photo shows an example of our "Flexi-Keeper" hooked to end of push rod and a control horn.

Control horn & wire are not included in set.

1st photo shows the .055" size with control horn for example, 2nd photo shows this part as cut.

1. Use in conjunction with an amp meter to test current to any one servo or between the battery pack and the entire system.

2. Use a combo of your amp meter and ESV to see how far your battery voltage is depressing at a given load.

3. Use in combination with our ESV to see what your voltage is while your system switch is on. A jumper plug is used to complete the connection when your doing volt only and no amp tests. Regular hobby battery test and charge cords (you probably already own) can be used to interact with this Y harness.

Here is how is how to use me:
To measure current. First set your meter to measure amps and set it one setting higher than you expect to measure so as not to damage your meter. For a typical aircraft you might start at 5 or 10 amps range to be safe. You can reduce the range later (if that is an option) once you know your not going to over drive it. For many digital meters you'll have only two settings, one low like 300mah or less and one for over 300mah up to 10 amps. Use the higher of these two settings for most applications. Unplug the jumper plug. The jumper plug is shown unplugged above at the top of the photo. Plug your JR or Futaba RX charge cord in where the jumper was (notice all black wires here) plug the banana ends of your charge cord into your meter (most meters use standard 4mm banana inputs) correctly. Your meter completes the ground wire connection between your battery and your RX or Servo (or whatever load your checking). Run your device and take your reading.

To measure voltage, Set meter for DC, if it has a set of ranges, choose a lower range like up to 10V (this setting should be above what you expect to measure). Plug the jumper back in and plug your charge cord into the other arm of the Y. Plug the banana plugs from your charge cord into your meters volt check inputs. Take reading.

If you have 2 meters, you can test voltage and amps load at the same instant. Also, with 2 Test Y Harnesses, you can take readings between the battery and also at a distant servo. Maybe you want to know how much voltage drop there is at the end of the line in your tail servos for example. In this case you need to know the loaded voltage at the battery and also at the distant servo to see what the actual drop in your wiring harness's really is. If you only measure at the servo your total voltage drop will be the total of the wiring and the battery and not just the wiring.

Not reccomended for any in-flight applications.

Tidy up and protect your servo wire. 3mm fits 1 servo cable. Works like Chinese finger cuffs, push ends toward center of piece to open up to insert wiring. Very nice for heli applications, keeps wires from straying and protects from friction damage. 3-foot packs available in Orange & Yellow. See other listings for color and size options.

Limited quantities, while supplies last... 

Example photo is of our .032 park flier size "Flexi-Keeper" retaining an L bent push rod and a control horn.

Control horn & wire are not included in set.

The Mini Hunter may also be powered with direct drive props if you like. Any two 12mm motors will fly it. For brushed use Twin 50XC motors. Remember, this model will get off in 12 feet, climb at 45 degrees or better, and is plenty quick with the brushed fans. You do not need brushless to have a cool model here, but we've got it to serve up to those wanting to build a monster.

Newest Power System? Another cool setup is twin 12mm 50XC 4.8V motors wired in series on 2 or 3S.

Specifications:
Finished weight 7.75-9 oz.
Wing span 23".
Wing area 132in. sq.
Length 19.5"

Build as 3 or 4 channels, requires 4 each .2oz or less servos, small RX like Berg Microstamp 4L RX, Castle Pixie 7 or GWS ICS300 for 40mm fans (yes one esc drives both motors for brushed). Twin Castle TBird 9's for twin brushless fans on 3-3 props. Use a high discharge pack, weight budget for the battery will accommodate 2S 640 to 3S 1000.

International shipping note: box size is 24 inches long and approximately 16oz. weight.

Note: True 20 gauge is so large there is no room inside the connector shell for insulation hence you get no strain relief. This wire is as close to 20-gauge as is practically possible while still allowing a thin silicone insulation jacket for strain relief into the shell and connector pin. This is our very best radio wire. See further description of wire types and strand counts in the bulk wire area.

Normally stocked in assorted colors. If you have preference, list first and second choice. Wire size is .062 (1/16"), puchasing an extra set of wheel collars is suggested.

WHILE SUPPLIES LAST, COLOR AVAILABILITY NOT GUARANTEED

Note: Stock machine made sizes and are lower cost and can suit many needs, find them in the connector category to fit your specific brand.

KEY: Think of a 1 legged stick man, the RX connector is the "Leg" and each side of the "Y" that connects to a servo is an "Arm".
