hi duckwing :-)
the alpha modells (
http://www.alfamodel.cz/) you had too in your post can be bought from "simprop" too. but in the simprop versions the servos are actually built in :-) (less work)
friend of mine bouth the 810mm wingspann coursair in the morning and after 2-4h work it was ready for flight. test flight was
nice and it is easy to fly..not flickry .
speed looks very nice for this scale compared to the original ones.
only problem he had in the coursair..engine and an other part was killed because of overheating. so just drill in some cooling holes in the plastic part that simulates the engine.
the other models, think with more work to do, but even more detailed you can find here:

think i really must start RC flying..our hole airfield is filled up with electro RC modells after we finished the real flying in the evening.
corsairs,bückers,and other stuff all around...lol
