I have to admit I've been mostly flying my several Avitrons (rather than helis) for my bird lately. But today I took out two of my nice 5888s to make sure they still worked properly and to recharge to 80% [optimal for storage]. Both needed minor tweaking to make absolutely perfect
again, one even req. using a hairdrier to reduce the bowed spanwise curvature ["elliptical dihedral"] of one blade each, top & bottom rotors, as well as then re-adjusting the root coning angles of each of the alu hinge-sides of those blades, of course!!
PRECISE Super-Smooth "sewing machine"/"Swiss watches" again ....!
a real joy!
