New Tailplane

Instinct F5J.  We are ready to start building the first tailplanes, the first will be 25g glass, Rohacell, 25g glass then we are going to try the 50g glass on the outer skin, this will give us some good weight comparison vs strength and dent resistance.  Once we are happy with the results we start our first wing.

To ensure that the cloth is pressed nicely into the complex curves of the mould both at the leading edge and the tips we chamfer the edges of the Rohacell, this reduces the 'step' and prevents air being trapped, this also increased strength and gives a blemish free surface finish at the edges of the core material. This is tedious and time consuming but well worth the extra effort.
