Quark 2M - Back to cutting innocent trees!

Fred,
I had planned on trying to reduce the expo on the controls once I had got comfortable with the flying characteristics. I will reduce the elevator throw a bit and try 30% expo for the next flight.
Thanks,
Martin.
Fred:
Hi Martin,
30% sound like a good start. You should not see much difference, just a bit less push on the stick.
The benefits will be a much sharper response of the elevator, a bit more in "phase" with the rest of the controls if you see what I mean :)
Let me know how it goes :)
Fred

Flew the Quark again yesterday. The winds were 10-15mph and occasionally 25° off the slope.
The model flew well with the elevator expo set to 30%. I will reduce it to zero for the next flight.
Everybody on the slope was surprised at the quality of the slow speed handling and the roll rate :D
With a couple of mm droop on the ailerons the model climbed very well.
Martin.
Fred:
Very nice Martin :clap:
I totally removed the expo on mine on the elevator. Much better I think, more "in line" with the rest in the controls for responses.
Glad you enjoy your Quark :D

Whoops, removed too much lead from my Quark and that old adage of to rear a COG one hectic flight with heavy landing was true. :(
Managed to break both carbon wing joiners, fuz was a little sad and broken. Wings not a mark on them.
Mending fuz was like a 3 D jigsaw puzzle put the balsa bits back in place and hold all square and add thin cyno. Did add some fuz reinforcing inside the fuz. Anyway all fixed and COG is now at about 65mm from leading edge which is very safe. :)
My question is how long do the carbon wing joiners need to be??
Is 320mm long enough for the front and 260mm for the rear?
If not I need some new Carbon fibre rods!
Feedback welcome, thank you.
