the 52 will probably be marginal unless the s.e. is exceptionally light. we had good luck with a saito 72. hovered fine, lacked rudder authority. we took flying wires off and counterbalanced the rudder; mostly to reduce vertical fin area. just cut it where the 1/4 in. stick goes across fin. it helped a lot, would maintain knife edge then. When the canopy blew off, the rudder worked even better! had plenty elevator. Hope this helps.
