I think it's going to be the right thing for these planes if you want them going over 220 mph though.
It not the servo alone...I´m (and a lot of my F5D mates) happy with Dymond D47 or d60, good enough for 220mph...and cheap (20€ )
They can handle 2s lipo
If you want to have digital servos...I would try Graupner Des Servos...cheap and proved in fast planes.
