I built a Telemaster 40 this spring. I did put the flaps on mine. I also used one servo per aileron which made rigging a lot easier. My suggestion to you is that if you do build it, cut the dihedral to 2 inches and not 4 like the plans call for. They are almost too stable with that much and very diificult to do much more than fly when you get good with it. I built mine with a AXI electric outrunner in it and the performance is unbelievable! If you built a few kits you'll notice that this one goes together a little odd compared to the others. The Germans build their stuff differently than we do. It's not bad, it is just different. It is easy to build and very satisfying. Good luck and keep us all up to date.[8D]
