Westland Welkin

On my "must build" list for 20 years, I've twice failed to get it quite right.  This first effort was 60" span all built-up for 2 speed 400s, but the wing was not strong enough.  This version is 48" span all Depron for 2 GWS IPS motors, and has flown but is underpowered. My only successful Welkin is the little X-Twin free-flighter!
