The aileron and flap servos fit in cutouts in the outer wing panels close to the control surfaces using long extension leads. Actuation of the undercarriage will depend on whether a mechanical or pneumatic retracting system is employed. This is a fast but stable model. Take-off needs to be held straight by careful use of rudder as the narrow undercarriage will tip it easily onto a wingtip. Acceleration is initially slow if you have an engine at the smaller end of the range, but once the wheels are up it accelerates quickly and the climb is brisk.
Simple aerobatics are straightforward, with all the basic manoeuvres being possible.
The model has a fast and flat glide and really benefits from the addition of flaps to steepen the approach. As with the take off, the landing needs to be carefully done so as not to tip it sideways onto a wingtip. Altogether a fine flying model which really looks the part in the air. The Spitfire is a metal skinned aeroplane with some fabric on the control surfaces, so the choice of balsa sheet and veneered foam wings is consistent with the desired surface appearance. The design is well thought out and has only a couple of weak points.
