im building my second ace seamaster. these arfs are really great float flyers. just dont over power them. they fly great with the recomended engines. i use a os .52 4-stroke and i can take off at 1/2 throttle. price is 199.99 at quantum hobbies with free shipping(and its a big box). kit is built staight and strong. i use fly wires on the tail. I attach a 2-56 wire from the stab to the fuse to give the T-tail some added strength because i tend to get a little crazy up in the air.
heres a great review
