Vinny mentioned: "second one has jr 3421s in the tail /hitec digs in the wings" - just wondered what spec they were.

I have just found the following spec's though:

Elevator: 2 JR 3421
Rudder: 1 Jr 9411
Aileron: 2 Jr 2721 or any good standard size servo.
Flap: 2 Jr 2721 or any good standard size servo.
Retract :Jr 341 or any mini size servo
Nose steering: Standard size servo

So that seems to answer my servo-requirements question.

Thanks a lot for the help guys.
