I have been flying a Tower high wing trainer for 6 months and was given a second trainer as a gift.
I would like to know the possibilities of setting up this one with 5 servos, to be used with flapperons.
Will it make more or less difficult to fly. Or would I be doing this just because I can or a learning experience. Would it float more and land slower or what. What else could I do to make this one different from my first.

Also with 4 channel, If I mix rudder with ailerons with rudder will this help adverse yaw. If yes, how much do you mix and will it affect takeoffs. I using JR XP6102 with Thunder tiger 46.

You CAN add a servo. It can be installed right next to the original one or you can install both in wing bays.
It shouldn't make it harder to fly as long as you don't add too much flaps and remember to fly first and worry about the flaps as a secondary thing.
It will probably float more unless you add too much flaps at which point you will be adding more drag than lift. This point is hard to reach in many trainers.
It should also land slower but how much is an unknown.
Changes? Less dihedral, tail dragger conversion, separate flaps (can't do this with 4 channels but you can't do flapperons with 4 channels either).
You can mix out some of the adverse yaw but you would be better off learning to use the rudder stick. IMO

I have a Hobbistar 60 with flapperons on it that never get used. I posted a thread about this very thing, All the advice I got from here was "you don't need them". I got a computer radio and a servo and put them on it anyway. Someday I am going to learn to take these guy's advice.

Flapperons are ok for short runways, but full strip flapperons will have a tendancy to put your nose in the dirt unless you simultaneously add enough elevator to compensate. They will also cut your roll rate. The only way you can use flapperons with a 4 channel is to adjust the linkage to the ailerons so that they are both down the same ammount from their center position. What you can do, is install a servo in the wing bay for each aileron, cut the aileron at 1/3 of its length from the fuse, and use the existing torque rods for the flaps. but to do that, you're going to have to remove and rehinge the ailerons. You can do any nomber of things to hold them both in preset positions, and later, when you get a 6 channel radio, all you have to do is add a servo.

Flaps are usually used as an airbrake or to make the stall speed slower. On a trainer, the stall speed is already so slow that with flaps you would almost certainly need to cut the engine to get it to quit flying.

As far as adverse yaw.... that is what trainers do. They have lots of dihedral. Your best bet is to take advantage of this problem with the airframe and learn to use the rudder if you haven't already. Try flying your airplane without using your ailerons, use your rudder to turn. That will add a new challenge.

Once you have learned all you can from the trainer you can either do as bruce suggests and remove the dihedral from the wing or convert it to a tail dragger, but I wouldn't add flaps, it's pretty pointless IMHO.

Keep in mind that there is a lot you can learn from a trainer, so keep at it until you are using the rudder as much as (if not more than) your ailerons and inverted figure 8s are no big deal, then get something a little more sporty.
