Hi the grip is 4.437 wide 3.200 high .500 hole back of the blade to center hole 1.125 drag link hole .312 thickness of grip 1.700
tips will need to be repainted there was packing tape on them of course when I pulled it of some of the paint also came off one blade.
They are about 5 years old. They have less than 5 HRS on them. The previous owner just quite did not under stand the start procedure and melted the turbine wheel. He could not afford to repair the engine and started parting it out.
New from Helicycle the blades are $4800.00 I'll sell them for $2500.00
If you are still interested I can post a couple pictures.
Pair of Helicycle rotor blades could be easily adapted to an experimental helicopter NACA23012 7.250 Chord 115 inches long
