I agree with you Ti-Pilot. It would be nice to see some titanium parts. It would work great in high stress areas like the mainshaft and feathering spindle. A titanium flybar would be great too since I keep bending them [:@]
A full titanium head might be a bit on the heavy side though as it seems that weight is very critical on helis this small. A well-machined high grade aluminum head would be great though because as you said the machining and material chosen by Helimax leaves alot to be desired.
I'd love to see an aluminum maingear with a replaceable one-way bearing. That would be awesome!!!
