5: ELEVATOR BALANCING, SERVOS, EXTENSIONS & LINKAGES
Some may say not to balance your elevators because it may cause flutter but I tend to differ, If
your servo gear mesh and linkage is tight with out any play there should not be a problem
whether it is balanced or not and if there is play in the gear mesh or linkage then you will
probably get flutter either way. By balancing the elevators you reduce the extra strain on the
servos gear train and with the precise digital servos we have today, balancing will stop the
bussing sound you will get from the weight of the elevators pushing down from the gravity.
To balance the elevators drill a hole approx. ½” in diameter with either a dremel or a drill on
the inside flat edge of the elevator, approx. 3½” from the corner of the leading edge, view picture
below. If you decide to use a drill, a tip to prevent breaking the elevators seam is to start out
with a smaller bit and then go bigger till it is approx. ½”. I have used about 80 grams of BB’s for
weight but anything like small pieces of lead, pellets, buckshot or birdshot will work in the hole
to get the elevator to balance. To create a centerline, use a ruler and make a mark with a pencil at
the edge of the elevator straight inline with the center of the shaft protruding from the elevator.
Use your finger on this pencil spot as a balance point and another finger as a resting area for the
shaft. Keep adding weight till it starts to stay down or not move in a horizontal position. Do not
let the elevator fall backwards from a horizontal position to prevent the weights falling to the
trailing edge. After you get it close to balance. You will need to take out enough weight to
account for the epoxy you are going to put in the hole to secure the weight inside. Approx. 1oz of
30 minute epoxy which weighs about 30 grams should do the trick. Mix and pour the epoxy in
the hole then cover the hole with some tape and let it stand vertical so the weight is on the
bottom but at a slight angle to allow the epoxy to cover the hole as it dries.
