First, turn on your radio gear and make sure the servos are
centered and all trims are set to neutral. Then attach the
pushrods to the servos first. If using the control linkages
(non-wooden type) use the clip type one to attach to the
servo end. These linkages can also be glued in place just to
make sure they don’t come off, but still cover them with
heat shrink and shrink it with a soldering iron tip.
Once this is done attach the linkages with a hook in them to the control horn and trim your carbon
rod. Then use a small amount of glue and the larger 1mm heat shrink to secure them in place.
You may use a soldering iron tip to heat the heat shrink.
The finished linkages should look like this. Heat shrink is used to secure the joints and the U
shaped hook can be used to make fine adjustment later (similar to the effect of using trim on the
transmitter)
These wooden sections are then cut out to allow the control surface to move. Finally test your
control surfaces with the receiver turned on. You may need to dial down the throw so the control
surfaces don’t move too much.
Adjust your elevator travel on your transmitter so that it clears the
rudder. Also check your rudder throws. The rudder should move just
15 degrees either side of center.
This will usually require you to dial down your rudder throws. Start
with small throws for test flying and increase as needed.
Note:
Control linkages attach to the outermost hole
Make two cuts to cut
out the block like this
Don’t forget to cut out here as
well from underneath
Cut out
Adequate gap
