experience before get wet First plane really no special requirements good pilot though prefer high-wing sport-type planes myself have flown wing load ings 16 oz per sq ft 22 oz per sq ft am now flying 185 oz per sq ft because find suits ani lazy flier low wing loading much amicable inthe air takeoff plane will also cruise half-throttle lower wing loading would descend higher wing loading Liberal use halfthrottle low wing loading gives flight times 10 minutes critical point water takeoff just plane starts climb out very easy pull up plane too soon before has built-up speed low wing loading will forgive high wing loading will snap-roll right will have dunking plane upside down water has no serious conse quences though can get quite frustrating lower wing loading pays off ways two
