AreoHawk Repair Kit

The repair kit contains: CA (Cyanoacrylate) glue. Quick drying hobby glue. Foam safe. This is fast drying glue used for small repairs in the field. Because it is foam safe it can also be used on the wings. Epoxy; 2 part (2 bottles with nozzles). This is like araldite and is used for repairs where one has the time to mix up the glue and allow it to set (4 - 12hrs). It is a 1:1 mix. Once mixed do not apply until it has set a little (approx 10 - 20 min depending on ambient temp). When it is runny it can spread to areas you don't want it. Clear bottle of clear liquid. This is a cleaning substance which is alcohol based. Used to clean areas to be repaired. For cleaning surfaces prior to using glue. Before using on the wings do a small test to make sure it does not remove the paint (it shouldn't but just to be sure). White synthetic powder Micro Bubbles. The purpose of this powder is to provide expansion. It is mixed in with the epoxy to provide filler as well as glue (approx 1/4 teaspoon to 1-2ml of epoxy). So if some foam is dislodged the micro bubbles can be used to fill the gap. However the expansion is not very large so is recommended only for use on areas where smaller gaps occur. One such repair is to reseat the RDS. The RDS is a carbon fibre open box slotted into the aileron and elevators where the servo arm acts on the control surface. If at any time this comes loose it can be removed and re-seated using the epoxy, micro bubble mix.

White cloth is fibre glass Yellow cloth is Kevlar Black cloth is carbon fibre

Depending on how much strength you need in a repair depends on which cloth to use. If the area around the repair has a particular type of cloth around it, use the same cloth to repair. Do not put carbon fibre near the antennas (telemetry & GPS).

In most common repair situations they are cracks along the side of the airframe. For these repairs it is best to open the crack by applying pressure near the crack. Then apply epoxy into the crack and allow the crack to close again. Sometime it is best to use some tape to close the crack, to hold it closed, while the epoxy sets (overnight). Remove the tape as soon as the epoxy has set enough to hold the crack together. This does not mean the epoxy has set properly so give it another 2 hours before flying.

In the field you can use the CA glue to make the same repair in the same method. This will allow you to fly again quickly. Points to remember: CA sticks to most things including fingers, electrical wire and clothing. It does not stick to plastic bags. So you can use the rubber gloves provided or a standard plastic bag to protect your hands. Only use clear plastic bags as the ink on coloured bags rubs off. If you glue a crack with CA you can then apply pressure on the crack, with your hand in a plastic bag using your fingers. This is a very suitable field repair.

Remember not to use glue on moving parts.
