When you get a new mobile sim embedded in a credit card sized plastic sheet, you typically discard the rest of that credit card sized sheet of plastic after pulling out just the sim card.  I believe Azhagu used that sturdy piece of plastic.

Yes anwar exactly the same thing. I think this method can be used only for small foamies with small motors.

Learning to Fly



Well, I think it depends on whether the model is a a tractor or a pusher.

In a tractor configuration, the prop is trying to take the motor mount forward while the weight of the plane resists this movement. For this reason, a strong firewall and strong bond between the plane and the motor is needed.

In a pusher configuration, the motor is pushing the plane so the force of the motor is actually strengthening the bond between the firewall and the plane. In this case, I am just using cellotape to stick the motor to the plane. It works

You should use some type of glue.  Hot glue or 5 minute epoxy are commonly used for this.

For a pusher configuration, double sided tape may work OK, as the motor pushes against the tape, instead of pulling away from it.

Double sided tape works great under pressure. I once saw on nat geo a strength test where two cars were pulling a cable joint by double sided tape in opp. directions!

Practice, and only Practice will make you perfect



Carrom Striker is another option, you can sand it to reduce its thickness, buy the cheap ones, it costs less, less weight and does hot cut easily

Removable nose, toothpicks, rubber bands. Toothpick pinning required as that is a 300 watt motor! See pics.

Theleabres. Shame on you. Guy has screws loose. You tell him  about blind nuts which are for (b)olts.

Simplest solution for loose mounting screws for elec motors is a drop of CA in the holes in the ply plate. Used this even today.

To all my friends "HAPPY LANDINGS"....



If one can get Gorilla Glue or PU30 D4 adhesive, this is very good as the glue expands when it comes in contact with moisture. Mix a bit of sawdust in glue and just a drop in your foamy or balsa plane will expand 2 to 3 times its original size. I use cocktail sticks (these are made of hard woods compared to toothpicks that are from soft wood) these are driven into the foamy's firewall, pulled out and a drop of Gorilla glue is added on each hole, cocktail stick driven in again......MOTOR MOUNT WILL NEVER MOVE..
(the black tiles are 600 x 600mm // 2ft x 2ft ...to give you an idea of size wingspan is nearly 50 inches)
