Scooter is in Vegas and our normal weather report will state 5-15 mph, this is normal. We get everything from dead calm to 60+ mph and it can all happen on the same day. Even on low wind days we get a lot of gusting and thermals. To design your own?? Why bother when it has been done for you and you can just buy the plans. My number one plane for our heavy wind days is/was the Kaos. I had them in both 60 size and the 80 inch. Neither one ever had a problem with our weather. Last year I built the Daddy Rabbit from plans. It was a class-C pattern plane in 1966 and the designer designed it just for an all weather plane because he had to travel around the country to compete. The plane won a national and a big pile of other events so it must have worked as planed. Mine is really stable in the wind. The other question is what do you want to do with a plane in the wind?? I enjoy flying the big Telemasters but that's just me, any of the bid high wing planes are fun in the wind. Weight seems to be a big factor, a heavy wing loading seems to be better in the wind then these light ARFs most the guys are flying and I tend to over power my planes just a little. Sometimes more then just a little but that has bit me in the butt once, my bad!!! I have taught students to fly in 20mph winds just so they know a trainer can do it. It's more a pilot problem with a mind set that keeps them grounded. After about 20 it tends to not be a lot of fun though but that depends on the plane. My 60 size Kaos has flown in some of our local heavy winds and other then the added power to fly into it the plane didn't know anything was different.
