OK, clarification: I at times run the 200 watts on 30, but generally about 70. Sorry I was not specific enough. Appreciate reading my post carefully enough to accuse me of illegal operation. ________

Since the published max windloads are at a relatively low speed (50 mph if I remember), is there a calculator to recalculate at higher speeds, or are there too many variables for this to be done in t
