.Check list, Check list, Check list. You would have remembered to put the flaps up.
As far as the forgetting to put the gear down. I use the gear like flaps, pull back on throttle slow and drop gear (flaps). And with the fix on the gear locking mech. I have never had a problem. Lee At least that's what I used to think until I got the Swift. That thing drops like a ROCK with the gear down. Landing the Swift is completely different from the KR, as you basically get over the end of the runway, drop the flaps, and come straight down! That's an aspect of Ken Rand's retractable gear that never occurred to me...we whine about how KRs float along in ground effect, but with retracts I'll bet it doesn't do that nearly as bad. Too bad they were prone to folding, and worst of all, you have to remember to put the gear down when landing!
