RE: props mvvs
The .60 runs perfectly with a 16x6 prop, so the .77 will have little work with a 15x4, and have spare to boot.
The APC wide, has good hovering potential, but is very heavy, and consequenly slow to respond to throttle.
A wood prop would be best. Eventually carved from a larger one. The Zinger would be my favorite to bash.
In every large prop, there lurks that smaller, prefect one.
