Gunny I did not use the 3rd flap on the removable tip section. But the 2 inner are functional. I use 50 % flaps for landing which is about 25 degrees and full flaps for take off which is about 45 degrees. I have started landing with 50% flaps because the plane doesn't slow as quickly in the flare and I get a smoother landing.

A warning on cross wind landings. If you have high crosswinds,, 15 mph + I would reco.. no flap landings. Also you are limited on crosswind cross control landings due to wing span and ground clearance. I have found that if you need to lower the wing and give opposite rudder you will be very close to the ground with the wing tip. Also once you have bank established and change rudder it will only change the yaw but not position of the plane over the runway. If you are off centerline and have max bank rudder will not get you to centerline as in a smaller model. Our runway has a safety fence and on my second flight I almost caught the fence trying to use rudder when close to the ground. Fly landings much like a 3 channel plane. You must be on centerline and elevator becomes your primary landing tool with ailerons only to keep the wings level is the winds. Rudder will only affect your yaw.

I would suppose a good way to practice would be fly a 3 ch. high wing trainer with no ailerons. Do this in crosswinds and it will be a good example of how the herk will land in cross winds. I am very cautious about cross wind landings. I flew in Mobile with 15 mph direct cross wind and have photos of the landing. You can clearly see the effects of the cross wind landings in the video.

If you fly in light and variable winds you will have no issue and can land with any flap setting you are comfortable flying. Happy Flying.. Jim
