I flew my Solius and m60. I tried the fox but there wasn't enough wind for it. Having the electric motor on the Solius helped a few times. The m60 few great- it handles light lift as well as big winds.
Robert and I stayed later and winds calmed, but the lift returned. Robert had his sloping machine, the mini Radian, flying great. So well that he couldn't tell when the gyro was on or off. We even had a mid air, but it just bounced off the Solius without damage to either plane. We left about 4:30.
It was fun having a beautiful dry & sunny day with four planes buzzing around!
What Chris didn't mention was how well the little umx Radian handled the slope. It was a delight. Easily managed the winds and stayed up on the slightest breeze. Could do big loops and relatively fast speed runs along the face of the slope.
Much, much better slope plane than I have any reason to suspect it would be.
If you have one don't hesitate to slope it even it the winds seem too high for the little guy. It easily handled the same winds that was keeping the M60 in the air. It can do it ... and do it well.
