Let us introduce the Rudder Master.
Below is a list of some of it's significant benefits followed by more detailed information.
1. The servos no longer fight each other causing high battery drain.
2. Near perfect neutral centering.
3. The bridge across the top of the units take the loads from the rudder and put them directly into the aluminum tray rather than the servo bearings.
4. Drive the rudder anyway you wish, pull/pull, push/pull, or a single push rod
5. Light weight, the entire two pulley assembly including the output horn weighs 4 ounces (not including the servos).
6. Less mAh per flight
7. More than enough strength to handle the newest high torque servos.
8. Smooth quiet operation with no metal to metal contact.
9. Easy conversion or initial set up, four 6-32 screws and you're ready to go.
10. Lots of BLING!
The Rudder Master incorporates the advantages of spreading the vibration isolation mounts onto a wide foot print with the mechanical simplicity, accuracy, and torque absorption of a cog belt drive. The majority of the rudder loads are taken off the servo bearings and transferred into the aluminum tray through the bridge across the top of the assembly. Most of the shock loads from the rudder are absorbed by the belt rather than being transferred into the servo gear train.
I'm sure you have noticed that after synchronizing your rudder servos at the neutral and end point positions you would still hear the wine increase when you moved the rudder stick to positions other then the three synchronized points. This is because no two servos are created equal and there will always be some disagreement between them in their positioning. The Rudder Master's cog belt has just enough give in the belt to allow the servos to take the positions they want to take while bringing the rudder back to the same neutral position time after time. This is a real plus for anyone who flies in the IMAC aerobatic competitions.
We have done extensive testing with the super powerful JR 8711 servos and the results have been excellent. The strength of the belt, aluminum pulleys and aluminum pulley splines exceed the strength of the servo gear trains by several factors. The Rudder Master comes complete with everything except the servos including the double shear output arms. These arms will allow you to utilize pull/pull, push/pull, or a single push rod.
If you are planning on using one of the 400 in. oz. plus servos on your rudder you should consider our high torque servo tray pictured at bottom right. It is specifically designed to overcome the problem of poor neutral centering that comes with mounting 400 in. oz’s of torque on a 2” by 1” foot print through tiny rubber grommets. With this design the servo keys onto four studs that protrude from the bottom of the tray and are tapped to accept a 4-40 SHCS. The servo now becomes an integral part of the tray. Vibration dampening is provided by four Mil Spec rubber grommets at the four tray corners. This increases the mounting foot print for the servo by a factor of 8 which directly related to your rudder returning to the same place every time. The tray and all mounting hardware weigh less than 2 ounces.
