ACCESSORIES

SWB

$18.00/pair Part# SWBcaf

IN STOCK

SWB's cable attachment fittings

They work well. You need two sets to do 1 airplane if you want to use them at both ends.

SEE BELOW - for the Kevlar or Steel pull-pull cable.

Included:
- Ball links
- 1.5" Titanium Turnbuckles
- White cable guides

* Brass tubing for crimping the wire is not included.

AIR WILD

$5.95 Part# AIRcaf

IN STOCK

Air Wild's cable attachment fittings (package of 4 - enough to do one plane).

They were redesigned for the higher loads of today's high torque requirements.

This is a nickel plated copper body with a steel 4-40 nut and rod. It offers 3/4" of travel.

It can be used with steel or Kevlar up to .059" in diameter.

I used this on my 35% Extra 260 using Kevlar cable. It's very easy to use and it has lots of adjustment. I just slipped the Kevlar through, tied a large knot and that was it! I put the parts together with just a couple turns of the threads. I really tightened it a lot, and there was still lots of travel left over.

This works with a variety of fishing line, steel cables, and Kevlar thread. The Nelson terminators must use the Nelson cable we sell, so the Air Wild offers more options.

I tried it and I like it!!

PULL-PULL CABLE

nelscbl

$4.95 Part# TBMppcsteel

IN STOCK

TBM 1/32" pull-pull twisted cable - 24'

We use this steel cable exclusively with Seiko servos. Strength is up to 2400 oz-in torque servo with 1" arm, or 9600 oz-in torque servo with 4" arm. (A Seiko 105 servo offers 1800 oz-in of torque).

Stainless steel cable is commonly used for pull-pull systems in the larger aerobatic and scale model aircraft. The advantages of using stainless steel cable is the high strength, no flexibility, and immune to temperature differences.

Steel cable is recommended for a pull-pull system that doesn't use pulleys though bellcranks are fine. This popular cable is suitable for any size R/C model up to 50% in size.

The cable is obviously metallic. The receiver(s) antenna should not be placed close and parallel to the pull-pull cables. This could have some effect to the operation of the radio. Carbon fiber, wire, and aluminum pushrods also require the correct positioning of the receiver antenna.

$2.95 Part# TBMppckevlar

IN STOCK

TBM Kevlar cable - 24'

We use this Kevlar cable with all rudder systems up to the Seiko servo.

Kevlar eliminates any radio interference problems which can occur with steel cable.

"I used the Troy Built Models Kevlar pull-pull cable as an initial rudder setup on my 28% Edge. I also purchased an offset 3” SWB servo arm and SWB wire tensioners. I was very disappointed with the wire tensioners because the white looping side that accepts the kelvar (or other pull-pull material) had a limited amount of adjustability. It is threaded just enough for what I felt a safe number of threads for strength and then there was no further room for tensioning. The include picture shows the threads bottomed out. The SWB system comes with a titanium turnbuckle but I ended up having to tighten just the ball link side. This was a major disappointment since I didn’t like taking off and on the ball links. Note that in the picture I installed one ball link on the top of the control horn and the other on the bottom so that the crossing Kevlar would not rub. Installation of the cable was very simple, a few knots and some CA to hold the knots is all that is needed to secure the kelvar. Do NOT use terminating crimps because this will damage the kelvar strands. I did not even try the metal pull-pull system for fear of radio interference so close to the 72mhz radio antenna, which is why I selected the kelvar. After reading a number of Internet posts I used the crossover installation method (right servo control horn to left rudder control horn.. I was never able to keep the system at the correct tension so I changed my airplane to a servo in the tail push pull system. In review I should have tried a straight installation of the pull-pull. My other reason for going to a push-pull was I needed more weight in the tail of the airplane. I did use the kelvar to connect my tailwheel to the rudder using a spring on each side of the root of the rudder and then the kelvar connected to tail wheel control arm. This has worked perfectly for over one hundred landings and being dragged through the grass during taxiing."
