This material shrinks easily with your covering shrink gun, lighter or other heat source. After shrinking, this higher quality tube stays flexible keeping your strain relief plans intact. Shrinks about 50%. 1/16 and 3/32 sizes are most popular for individual servo and park flier pack wires. 1/8" for strain relief on 2 pole 22 gauge battery pack wire, larger sizes for larger wire. Shown at right is 3/8" for locking together servo connectors you won't be able to easily inspect later.
Measurement is inside diameter: 5/16" / .3125" / 8.0mm Very economical to keep plenty of this material on hand. You'll find many uses, we even use the smallest size for wheel collars on some of our kits.

This nifty Y harness invented and available exclusively at Radical RC is handy to use for loaded voltage and current testing of your radio system. Here is what it can help you do:
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.
Custom Extension as listed above except Female-to-Female plug. Used for some power box and other misc. uses. This custom extension will have 2 ends that look just like an RX or Y harness arm. Accepts your servo ends on both ends.
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.

WHILE SUPPLIES LAST, COLOR AVAILABILITY NOT GUARANTEED
We can hand make Y harnesses to almost any specification. Use these special harnessed to reduce the connectors (and resistance) in your electrical system. Also, there is nothing like a tidy radio compartment and proper length harness can help you get there. Use the drop down menus to indicate your preferences. Generally we size these by measuring from the back of each connector. So the overall length will be greater by connector shell length. Twisted wire can be adjusted slightly in length by changing the number of twists. We try to get within about 1/2" of your spec. Please order long enough to compensate for minor variance.
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".

Our Comet captures all of the jet-age looks and excitement of the sleek 1950's design it's based on. With the included jigs, this delta wing can easily be built by those with experience in constructing built-up kits. Please note that this is NOT a beginner's kit - it requires building and flying experience to be successful.
Flying the Comet is a blast. It's not overly quick and has pleasing flight characteristics that make it fun to fly. Even at low speeds it is well behaved and has no surprising tendencies. The Comet can be powered with either an electric or glow powerplant. We've designed the fuselage with built-in hatches so you have quick access to either your batteries, fuel tank & radio system.
Specifications: Wingspan: 39.5 inches Wing Area: 470 square inches Length (airframe only): 32 inches Weight: 3 - 3.5 pounds Radio: o 4 channel system (with elevon mixing) o 3, 40-70 in./oz. servos for elevons and rudder; o 1, 40-70 in./oz. servo for throttle (if using a glow engine) Power: o Electric: .25-sized brushless motor, 60amp esc, 3s lipo o Glow (.19-.30 engine, 4 ounce tank, fuel tubing) Features of the Comet A Retro, Delta Wing Flying the Comet is a blast. It gives jet-like looks and stability without being overwhelmingly fast. Stability at all speeds make it easy to fly and easy to land. WEB-LOCK Construction There's nothing else like it. Build our wings, straight and true - with a minimum amount of fuss. Premium USA Hardware Included in each Old School Model Works kit is a premium hardware package. We only source our hardware from brand-name, USA manufacturers to guarantee the best quality. Rugged Landing Gear We include sturdy, pre-bent main gear, steerable nose gear assembly, and wheel collars. The 1/8" diameter wire can absorb quite a bit of abuse for those no-so-good landings. Bottom hatch Held in place with thumbscrew, this hatch gives you easy access to batteries or fuel. Canopy Also included is a clear, pre-formed plastic canopy. Additional items needed to complete the Comet kit: o 4 channel radio and servos (elevon mixing is needed, so a radio with mixing is needed) o Propeller o Engine/Motor mount & mounting hardware o Pushrods (two 5" for elevons, one 18" for rudder, one 12" for throttle if glow powered) o Clevises for the pushrods (6 if electric, 8 if glow). o Three 3" diameter main wheels o Covering

Did you ever get to see a Wright Flyer fly? Did you ever dream that someday you'd get to wiggle the wings on a Wright machine? I'm betting during all those many months of testing, planning, designing our famous Wrights went to bed wondering what it would be like. Then they did it. Now, you can do it. This conversion kit combined with the parts from two GWS Slow Stick slope glider kits (no longer available, discontinued by GWS) will produce a sport scale 1905 Wright Flyer. This model from the side view is scale having all the struts the original had. Omitted are all the flying wires and control cables. All the fiddly bits included on a perfect scale model (that break every time you land one) are gone. My intention was to design a model you could fly 10 times in a day if you liked and not once or twice a year for special occasions as you'd probably choose to do with a pure scale model.

How does it work? If you look close you can see our unobtrusive elevator servo (we used a GWS Pico) on the canard support strut. This servo drives the top canard which in turn, drives the bottom canard through a simple transfer rod. The canards move up and down together on thier own individual pivots like the original 1905 flyer. The rudder servo is adhered to the bottom of the bottom wing with a Dubro Micro Push rod (1/32 wire in clear plastic tube) driving the rudder. The rudder moves like the original 1905, both together. Perhaps the most exciting feature is this model flys with real wing warping. The outside wing strut assembly has a servo hidden under the bottom wing driving a diagonal rod that appears to be a simple bracing rod in the scale location. Forget the Eindecker like wings, wouldn't it be gross if this model didn't turn by real wing warping? You're going to love this feature every time you show how it works.
How does it fly? I was amazed, after some initial hiccups working out the right setup. We've refined CG and throws until it flies more or less like you'd expect a trainer to fly. It is a bit draggy so you tend to fly with a middle throttle position most of the time and you will want to be comfortable flying with both hands as this design likes rudder inputs. However, you'll soon agree it flies like a trainer. Provided in the kit is the CG you need along with servo horn lengths, control throws and even exactly where to trim the canard for that first flight.
How does it build? This is not a normal kit, it's mostly nut and bolting with some foam trimming and fitting here and there a little gluing and some finishing (staining). If like me, your favorite ever childhood toy was an Erector set, you're about to feel young again! Now I know you hated those square nuts and slot head screws (I did) so we included all hex wrench driven button heads and ny-lock nuts. There is a surprising amount of aircraft ply in this kit. The main structure starts out as a 24"x24" section of 1/8" thick air ply (cuts slower on a laser) and it's packed tightly with many parts. Needless to say, there is a lot of laser cutting time here. It has the longest hardware list of any kit we've ever designed and the longest instruction set I've ever written including several drawings/templates. Ron, who built both of our in-house prototype models said he needs 3 work days to complete one. So, please plan enough time, it's very important to us that you actually finish it and get it flying. I want to hear the joy in your voice and see the pride on your face when you tell me about it at the next show.
Whats included? All the hardware needed that isn't already in the Slow Stick kits is included here. All fasteners are good quality allen head bolts with lock nuts. There are 88 washers and you can guess how many nuts and bolts.
What do you need to complete? Add 2 motors (max 2oz, 800-1200 KV), 2 stick type motor mounts, 2 ESC's, APC counter rotating prop set, electronics (2 each 6 gram servos, 2 each 20oz torque servos (we used HB-65's), and 1 each 3S battery 1800-2200mah. Extensions and Y's. For motors under 1000 kv, use 10-4.7 props, 1000-1200 kv use 10-3.8 props.

Special notes about electric from Dave: This model makes an excellent electric conversion. My first large electric was one of these on 20 1750FAUP Cells. Yikes, I'd love to do another one with modern packs! Here is how I'd do it. Yes, this is same chart as the 4 Star 40, similar weight and wing area. An under recognized yet excellent electric conversion model. Good weight to wing area. A little troublesome to get large NiMH packs into due to the wing tube. However, with Lipo's it's super easy to fit the pack. Below are my suggestions for a range of practical power systems.
