Lightweight planes fly better. For some reasons why, CLICK HERE to go to the "Lightweight Planes Fly Better" webpage. This webpage has some examples which may interest you.

All the clevis' and horns offered below are specifically for giant scale airplanes. I prefer the Hangar 9 swivel clevis and horns because of their adjustability, though some planes do not have hard points which will work with bolts. Some planes must use fixed horns.

Most engines are not set up for the throttle and choke to use standard clevises, so we offer the ballsnap which has proven to work the best.

BALL BEARING HORNS

BALL LINKS

TBM Ball Links

$3.99 YOUR CHOICE

RIGHT HAND Part# TBMballlinkR

IN STOCK

One Pair of 4-40 Ball links with aluminum screws and locknuts.

These are a must for the double truss control arms. They also work well with aluminum arms. The load puts a twisting force on the arm. Due to this twisting force, do not use these arms with plastic servo arms because the arms will twist causing control surface flutter.

double ball link

$5.99 Part# HAN3619

IN STOCK

One Pair of "double" 4-40 Ball links HD (heavy duty) with aluminum screws and locknuts.

Available in Right Hand thread only.

These are for connecting servos in line. Depending on how you want to set up a 2,3,4 or 5 in line rudder system, use the double links between the servos. The servo furthest from the cables needs just standard ball links, the others need doubles. You can use a single on the last servo as shown, or use a double, depending on your connecting point. Shown is 3 servos with a bellcrank. The bellcrank connects to the cables so that there is less strain on the last servo's case. Nowadays, with the strong cases of the JR-8611 and Hitec JS-5955 servos, it is not necessary to use a bellcrank. In between each servo, use a 1.5" titanium link. Though the double ball links are all right hand threads, you can cross thread a left hand titanium link end into a right hand ball link without a problem.
