Question: My VMAR model comes complete wtih Flaps. Do I have to use them or is usage optional?

Answer: No you do not have to use the flaps. Although we have provided flaps with the model, you can simply lock the flaps in place at a neutral position and fly without activating them. We'd suggest that if you are going to go that route, install the control horns to the flaps and run the control rods to a fixed point near the flap servo cavity trays. Some folks actually mount a servo wheel to the servo cavity cover and attach the control rod to the servo wheel or even install flap servos as they would normally do for flap operation but don't hook the servos up to your receiver. This latter solution in effect has you all ready to use the flaps should you decide to later on.

Question: My VMAR model comes complete wtih flaperons. Do I have to use them or is usage optional?

Answer: No you do not have to use the flaperons. Although we have provided flaperons with the model, you can simply use them as ailerons. You will need a computer radio to make the ailerons work as flaperons and this is entirely optional... they will work just fine as ailerons only.

Question: What are Flaperons and what is meant by the term Flaperon Ready?

Answer: The term Flaperons is used to describe Ailerons that can act as Ailerons AND act as Flaps. When we design Ailerons so that they can or must use two servos the model is Flaperon Ready.

The Flaperons in a Flaperon Ready model are not mandatory but we have designed the model so that the Ailerons can be activated as Flaperons if you use two servos for the ailerons and a computer radio.

Better Answer: Flaps are generally used for take offs and landings only. They hang down from the back edge of the wing and increase the lift of the wing enabling the model to take off and land at slower speeds. Landing at slower speeds can make landing a little easier on the nerves. Flaps go down only.

Ailerons are used all the time in flight. Ailerons go up and down.

By using two servos and a computer radio it is possible to use an Aileron like a Flap while still using it as an Aileron. This is called a Flaperon.

When we manufacture a model we always include Ailerons. When we design Ailerons so that they can or must use two servos the model is Flaperon Ready.

To take advantage of Flaperons in a Flaperon Ready model, you must use two servos for the Ailerons and must have a computer radio.

Question: My VMAR model came with a long aileron running along almost the entire trailing edge of the wing panel. My model also came equipped with four servo mounting bays and instructions for the optional cutting of each single aileron into a flap and aileron or flap and flaperon. I have cut each single aileron as instructed. Should I seal the exposed wood ends of each of the resulting control surfaces? What should I use for sealant that will stand up to fuels and oils?

Answer: Yes you should seal the exposed wood ends so that they are fuel proof. You can use ZAP-CA as a quick sealant. Just apply a small amount at a time and let it wick into the wood. A better solution would be Pacer Finishing Resin which is a thin two part system that you mix together in equal amounts and then brush on.
