only clip it if you can already fly well.. generally more power won't help with the wind, unless you are underpowered and the wind is carrying the plane away from you.. weight and size are large issues when it comes to dealing with the wind.. as well as the wing loading.. if you have a big wing with lots of lift it will have a tendency to catch the wind more than a smaller wing with more weight.. also a large flat sided fuselage, such as a cub, will catch the wind and push it sideways.. the best thing to do is to get a ~60" wingspan balsa plane, something such as a sig four star 40 would be a good step up from your super cub if you can fly it well, and the 4 star will handle 10mph winds fairly well and higher winds with experience!
