After much prep I tried to fly my brand new Dymond Blitz. I laterally balanced the wing, noticing the right wing was heavy right out of the box. I taped the antennae on top of the left wing (behind the thickest portion of the ribs). On seven attempts with power (a 05 with a 12x8 pusher prop, the wing rolled left and dorked the lawn.
What is your opinion? Should have left the right wing heavy? Antennae became a stall strip? Excessive torque?

Dymond suggested the wing may have been heavy originally to compensate for the motor torque. Any suggestions?

Dan :stupid:

It may roll that way from torque. Try throwing it without power to see if it is the airframe doing it. Right trim in the ailerons or down/right thrust in the motor might also help. You may have to launch at lower power and then let it build speed before powering up. Without a rudder to keep it straight torque may have more effect than a conventional fuselage. Hard to figure out when all you have is a few seconds of flight time to watch it. Do you have a good zero on the ailerons? One might be a smidgen off of neutral.

If anything, I was progressively giving the wing more right aileron trim but to no avail. I did try a highstart on only the first attempt but the CG was too far aft (although forward of the recommended 220 mm from leading edge!!!! I was able to cut the motor quickly and flatten the landing out for six out of the seven flops.
