Heavy duty 22 gauge with universal gold plated plugs.
The best for giant scale aircraft.

Check out our "Organizers" section to keep all your wires organized!

Note on twisted extensions: If you are still using 72 or 50 MHz transmitters instead of the new 2.4 GHz or Spread Spektrum technology, twisted wires are suggested. If you are using the new technology, twisted wires offer no advantage to untwisted wires. Twisting extensions eliminates interference caused by stray signals being picked up by the signal wire in the old MHz systems. The wire can act like an antenna. This is rarely a problem, but if you have an intermittent interference problem this may be the cause. The signal wire (usually orange or white in color) has little current running through it. It tells the servo what position it needs to be at. The red and black wires have higher current in them as they provide power to the servo. Only the signal wire will pick up stray signals due to the low current. Twisting the wires in effect wraps the signal wire around the power wires which cancels out electrical noise. The noise is called electro-magnetic interference, abbreviated to "EMI". Typically extensions which are around 3' long cause more problems because they are the length of a receiver antenna, but extensions of any length near a gasoline (spark) engine ignition system can pick up EMI from the engine's ignition. DA, 3W, ZDZ, and other ignitions are now shielded so well that this is rarely a problem. Also, resistor sparkplugs are used which keep EMI down. For these reasons, we offer only twisted wires.

TBM SERVO EXTENSION TESTING

TBM conducted its own servo extension testing using the equipment shown. We found that adding a single servo extension (22 gauge with universal connectors) between the Rx and the servo will cost you 1.5% - 5% of your power to that one servo. Adding another extension will cost you another 1.5% - 5% and so on. In one of the many tests run, I put ten 6"extensions in series and measured a total drop of 15% of the maximum torque that a single JR-8711 could put out. In another test, I put ten 48" extensions in series (40' of extensions) and found the drop in power to be 55%. Therefore losses due to servo extensions is a combination of plug losses and wire resistance losses.

POWER LOSSES IN SERVO EXTENSIONS
 

SERVO EXTENSION LENGTH EXPECTED TORQUE LOSS
6" 1.5%
12" 2%
18" 2.5%
24" 3%
36" 4%
48" 5%

WHAT'S THE BOTTOM LINE OF THE ABOVE TESTING?:
* With proper servo sizing, you will not experience any difficulties using extensions.
* Never use extensions between the battery and the Rx. If you need more length, splice in additional 18 gauge wire.
* Use the shortest length extensions possible.
* Use one long extension instead of 2 or more shorter ones.

WARNING - Gasoline and Turbine powered R/C model aircraft are not manufactured to withstand unlimited G's. Any R/C model aircraft can fail, be it a wing folding up or a fuselage breaking in half under too high of a load. Just as any full size aircraft, model R/C aircraft have a maximum G rating. Because you are not in the plane flying it and experiencing the G's and reading the G-meter, it is more difficult to judge the G's on the aircraft, and it is very easy to exceed the limits of the aircraft. Understand that if you perform a snap roll, parachute, wall, blender, knife edge loop, or pull hard on the elevator at almost any speed, you can be putting in excess of 15 G's, even in excess of 30 G's, and most aircraft can only designed to take 10-12 G's. If you perform any violent maneuver, you can break your plane. When I perform hard maneuvers, especially for the first time on an airframe, I am prepared for a failure and am prepared for it as best I can be. This mainly includes performing the maneuver far enough away from spectators that in event of a failure that I am not endangering others. In addition, be prepared for the manufacturer to not pay for a new airframe which is broken during flight. It is common practice for any manufacturer to not replace an airframe which breaks in the air or upon landing. I have only seen manufacturers replace airframes when they have received many of the same failures and the manufacturer determines that there was a design or manufacturing error. If you break an airframe, and you are the only one to do so, then it is probably not the fault of the manufacturer. Please fly safely, and avoid full throttle operation other than at low airspeeds.

R/C model jets, warbirds, aerobatic planes, DJI S1000 Octocopter, and UAV Unmanned Aerial Vehicles to name a few are not a toy! If misused, it can cause serious bodily harm and property damage. Fly only in open areas, and AMA (Academy of Model Aeronautics) approved flying sites. Follow all manufacturer instructions included with your plane, radio, servo's, batteries and engine. Aircraft manufacturers guarantees each kit to be free from defects in both material and workmanship at the date of purchase. This warranty does not cover any component assembled by the customer. All parts of high stress must be inspected and reinforced if necessary by a competent builder. Some parts should be glued again. High stress areas such as firewalls, motor boxes, wing mounts, landing gear mounts, etc., are areas of high concern. Seek help if necessary. In not case shall TBM be liable for the cost of any product it offers which is not manufactured by TBM. The liability to the manufacturer cannot exceed the original cost of the purchased item. Further, TBM reserves the right to change or modify this warranty without notice. In that TBM has no control over the final assembly or materials used for final assembly, no liability shall be assumed nor accepted for any damage resulting from the use by the user of the final user-assembled product. By the act of using the user assembled product, the user accepts all resulting liability. The kit manufacturers have provided you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and fly ability of your finished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model. It is the user's responsibility to inspect each component for worthiness.
