However, most of the times I have flown it I would have called strong winds relative to the size of the model. Is it best to wait until I test it on a still day and then test/adjust the plane for motor angle?
If the wing section is quite cambered (Has much more curve on the top than on the bottom or is flat on the bottom and curved on the top) then the faster it flies the more it will want to climb.
You can counter this by angeling the motor down if it's a tractor or up if it's a pusher, or by adding some small ammount of down elevator mixed in with throttle. Some combination of both might well be the most helpfull for a zoomy wing section.
