Flaps add lift, but also add considerable drag, and slowing the plane too much with or without flaps, will lead to a tip stall.
Dennis-
Or a regular stall.
Technically, there's no such thing as a tip stall, it's just that sometimes, one wing stalls before the other.
In either case, without doing some wind-tunnel testing, or finding someone with the same plane who HAS installed flaps, we won't know what they will do to the flight characteristics. But don't try to land it like it's a Piper Cub! It was never designed to fly that slowly.
