I have a seamaster that I got 2nd hand havn't flown it yet. Have seen it fly tho--looks like it will take a long run to get airborne at least 150- 200 feet. with slo throttle advance@ even longer to land, it lands at a good speed.
this one is heavy it doesn't appear to have been repaired but still weighs 7.5 lb or so with a.46 in it.
