Caution: This RC model you will build and fly is not a toy! Although it may seem to be light and slow in flight it is capable of serious bodily harm and property damage. It is your responsibility and yours alone to build this model correctly, properly install RC equipment and motor, test the model and fly in accordance with all safety standards (and common sense) as set down in Safety Codes valid in your country. If you are just starting RC modelling, consult your local hobby shop or an experienced modeller in your local RC club to find a good instructor.

You must build the model according to the instructions. Do not alter or modify the model, as doing so may result in an unsafe or unflyable model. Take time to build straight, true and strong. Use proper radio and other equipment that is in first-class condition, properly install all the components and test their correct operation before the first and any further flight. Fly the model only with competent help from a well-experienced modeller if you are not already an experienced RC pilot.

Recommended glues

Unless stated otherwise, use medium cyanoacrylate (CA) glue (KAV56.9952 Power CA Medium). D-box sheeting and wing ribs are better to be glued using a water-resistant white aliphatic resin, like our KAV56.9960 White Glue SUPER (alternatively, you can use this sort of glue for most of the wood- -to-wood joints). The highly loaded parts (wing roots, wing main spars, firewall etc.) should be glued together using 30 minute (or slower) epoxy offering high strength and enough time for the correct positioning.
