The Rocrow uses a single elastic band to hold the wings to the body. This is very secure, but also allows a degree of movement between the fuselage and the wing which diffuses impact. In a big crash we want the band to break instead of the model!
We initially used black bands but found the dark pigment made them perish quickly. We now use brown natural coloured bands with great results. You can use any elastic bands, just make sure they are not too loose or else your wings will pull away from the body slightly in flight. Other then that it’s all up to you!
Put the band over the tail, fit the wing, and then pull the band over the top of the wing and over the nose. Make sure the band runs over the carbon ring in the tail, it’s there to stop the foam from being crushed.
