Additionally, a basic performance parameter that you should want to meet would be for your aircraft to be able to perform a go around with all the deployable drag hanging out. I know my KR will climb, although not crisply, with full flaps hanging out. I recall Mark Jones writing about how exciting it was taking off with the belly board hanging down once. With both deployed, your climb performance may be in the negative numbers, which is not a desirable trait.
