Be advised the Kadet Senior 'ARF' has ailerons and to fly without would require the need to deadend the aileron pushrods. The Kadet Senior 'Kit' comes without ailerons and has a two inch shorter wingspan. Agine the Kit is a kit not an ARF it is a box of lumber and hardware and plans. It is to be 'built' not 'assembled'.

Both are superb trainers but a more ideal engine size in a two stroke for either is a .61.

On the other hand the LT-40 is as successful as a long time trainer and just as superb, the .45 would be ideal. The kit I think now discontinued and the arf version both come set up for ailerons so agine to go without would require deadending the pushrods.

And as has already been noted if you learning mode 11 then to fly with three channels the rudder

is plugged to the aileron port of the Rx.
