Although I value ideas and suggestions I get on another form, I thought I'd pick more brains here.
I have a micro lite heli project with counter rotating rotors that I have made of laminated marine plywoood with a top cap of 1/4" solid oak combined with the 3/4" marine ply to come up with 1" thick. The rotors are 48", 8" constant cord. I feel I need to glass the rotors. Some say to use epoxy resin and some say polyester will be fine and cheaper. Thoughts??
I may have to cut holes aft of the 25% balance to lighten the aft part of the blade for balance. Is it really necessary with a solid 48" rotor blade? If I do cut holes I would probably fill with foam and then glass. I understand polyester resin will eat the foam and the need for epoxy resin. Thoughts???
If polyester will be fine on the wood, is there a special glass I need to get as far as weave and weight of glass fibers etc. The glass actually will only help keep the ply together and protect the wood as I see, not to add strength to the rotor but some. I would appreciate any good input on this. I have an album of my build on another site if anyone is interested. Thanks
