Twist:

Their appears to be some advantages to having a relatively high twist, say -8º.

    1. More lift in hover and slow forward speeds.
    2. The sections of the lower blade will have a greater pitch then the section of the upper blade located directly above it. The retreating blade is the retreating blade and it will therefore have even greater pitch, which is good, but it's angle of attack will not be any better because of the low relative air speed.

Consideration for Initial Testing:

Posting on PPRuNe by bugdevheli Aug. 8 / 03

The blades on Bug 1 were hand carved/planed using templates, the wood was spruce. when the shape was correct, i applied a layer of glass fibre and then finished of with a gel coat to put the balance and centre of mass right. The finished blades gave me no problems at all.
