G'day

A Kadet Senior built from a kit and built to the plans does not have ailerons or flaps. It has a lot of dihedral too. The dihedral makes it want to keep its wings level and makes it yaw as well as roll when the rudder is used.

On my 3 channel Kadets, I put the rudder on the aileron channel; on my four channel Kadet, the controls are in the normal channels. This makes swapping from three to four channel planes easy as the main "turn" control is always in the same stick. The downside is on the ground. Three channels are steered from the aileron stick and four from the rudder stick. This is no great problem though.

To turn a three channel Kadet, you start the turn with the rudder then once the plane has rolled (a secondary effect of the rudder) in the direction you want to turn in, you add up elevator to keep the nose up AND to keep the turn going. Once the turn is started, you can release the rudder and it will stay in the turn so long as the elevator is held up. When you a finished the turn, you release the elevator and the plane will roll back to wings level. You can also stop the turn more quickly with some opposite rudder.

As soon as you reduce the dihedral and add ailerons, you now use the ailerons to start that initial roll and the plane will also yaw in the direction of the turn. You also then complete the turn by holding up elevator to keep the nose up. Again, you finish either by just letting go the ailerons or by giving some opposite aileron to level the wings.

I have several Kadets. Most are built to the plan but on has ailerons. It has about half the normal dihedral. It can be turned either with the ailerons or the rudder but it is neater with the ailerons. But on both cases, it is the elevator which actually pulls it through the turn which keeping the nose level. If you go into a turn with either rudder or aileron and then hold the elevator, it just stays in a banked turn forever going happily round and round.

People look at my Kadets and think they are great big floaty unresponsive lumps. Nothing could be more from the truth. They are really extremely agile if you push them around. Flying them inverted is fun. They really don't want to do it but they will. You need plenty of height as without ailerons you cannot really do a proper roll and have to come out of inverted with a half loop in the direction of down and as a result, you need plenty of height to do this.

Sounds like your model was engineered to take the Saito 91 so it should be fine. Just go easy on the throttle and make sure you have a nice low idle so it will stop or it will just want to fly on forever at idle.

As an aside, I was flying a Telemaster Senior (8 foot wing) yesterday with a Magnum 61 four stroke. It takes off in about 10 feet even with that relatively small engine and then putters around. I don't find it as nice to fly as the Kadets but I am using it to brush up on my rudder use. It really needs some input from the rudder to turn well.
