where did you get the heli motor/collective/etc parts? This is an interesting idea that I might take a shot at here once I have some more time.
The heli parts came from a pair of KDS Innova 450BD helicopters that I bought from a gentleman for a very reasonable price. I believe he owns this site: (http://www.kdsmodelsusa.com/ENTRY-LEVEL-KDS-Innova-450BD-Combo-FBL-p/kds-450bd-fbl-combo.htm). I actually bought them a year apart, and it looks like they're no longer available. The kits were complete aside from the battery and receiver.
From those kits I used the central assembly minus the tail bits and redesigned and 3D printed new side plates to match the Osprey design. I actually used a photo of the original plates to help place all the mounting holes. I originally used the KDS ESCs that came with the kits, but recently purchased a pair of Castle Talon 60 ESCs to replace them. The Castle ESCs have a proper governor mode. I'm sure I'll reuse the other ESCs in an airplane.
If this whole thing works out, I'd like to replace the rotor head with a 3-blade model. I need to take proper measurements, but I'm thinking a pair of these would work: (AliExpress). I'd also like to swap the symmetrical blades for more efficient ones like this: https://www.rotormast.com/product-page/twisted-blade-set
