Rudder servo tiller arm?

Iíd like to install/build a rudder servo tiller arm like those used in rudder servo trays. Anybody know of a source? Use a servo case? I donít like pull-pull wires attached directly to the rudder servo. Thanks, in advance.

What you're talking about sounds like a bellcrank... and yes, SWB is the place.
Several different sizes available.

Perfect, thank-you. I use SWB all the time and never saw these. Makes my day for a nice EHMW Ultimate 1.85m Kit.

You're very welcome. SWB is great stuff... it's so functional, but yet it's great bling too... you can't go wrong.

Good luck with it.

Essentially, these bellcranks are the included components used in the SWB servo trays. If you have an SWB multi servo tray hanging around, it's got one of these bellcranks on it... whether it be a single, dual, or triple tray... You can also use these if you have a tray and want a different bellcrank(longer/shorter/etc..).... or use them just like you are by apparently having your own servo mount... So yeah, just an FYI I figured out quite a while ago.

Again good luck with your Ultimate!

SWB really needs to make a servo arm removal tool. I finally found a gear puller that works perfectly when setup perfectly but it is like a monkey and football kinda thing getting started.

hehe - building is fun and adding a bellcrank and a high-torque servo to a plywood tray will look right at home. Interestingly the rudder servo goes really low in the bottom of the fuselage in order for the existing pull-pull wire exits so it will be by itself and hopefully out of the way.
