Maiden flight of Graham's Multiplex Cularis sail plane,
Oct 2013 -
Ancaster- Ontario- Canada.
This Cularis model, as initially set up, as per Multiplex instructions, had a tendency to tip stall very easily and quickly without warning.
Turns required both rudder and aileron input.
On turns, the model tucked in the nose and spiraled down.
On power, the model tended to point/pitch the nose up and then go into recovered stalls.
Down elevator was required during powered flight.
Less power, less "down" elevator was required.
Future modifications are to set the ailerons with 1/16th to 1/8th UP reflex, increase the aileron UP throws, and move the CG slightly forward to make the model nose heavy.
Down thrust will also be added.
Compared to a Radian Pro glider, this is not a friendly "floater".
The Cularis is a heavier, faster model.
