Okay so I cant do a quad just yet, but I do have a decent sized co-axial that I enjoy, but I would really like to expand on its basic performance.
Is it as easy as switching out the motor and esc and loading a decent lipo for power?
The co-axial is never going to be as agile as a quad, but those who have seen me drive RC would agree this isnt a bad thing maybe. Extended flight times and ability to carry a camera would be nice and Ive even spotted something in Maplins that opens the chance of some recorded flight.

I have an FPV camera thats dying to get airborne too.
