RE: Jetmach Sport E for Kolibri
Tailplane done.
The plans call for a bass 'spar' at the trailing edge. I have used balsa instead and inset a 1/8 x 1/2 spruce spar further forward. I have also added a couple of 1/8 x 1/8 spruce ribs. None of this is probably necessary but I don't know how much extra stress the turbine will put on the model so I am going a bit over the top. Hopefully I haven't put too much extra weight at the back. Time will tell.
