I just finished mine. No real issues so far. One thing I did was go over all the joining areas in the fuselage and run a bead of epoxy. Mine seemed to not be glued together very well. It may have been just fine but I didn't see a lot of glue around the joints. I am powering mine with a GMS .76. I am going to maiden it using standard servo's but I am going to buy metal gear servo's ASAP. I fly off a grass field which is much too wet to fly off of right now. Will have to wait until the flying field dries out some. Also, I bought the Airtronics RDS8000 and the receiver that goes with it. This will be my 1st 2.4 bird. I have to say though, the 300S is a really nice looking aircraft, i just hope it flies as good as it looks. I currently fly a World Models Clipped Wing Cub, Senior Telemaster, two Kadet Seniorita's one of which is on floats, an Extreme Flight Vanquish and a GWS Formosa. This is kind of my move on up aerobatic airplane. I don't have much desire to fly 3D but would like to be able to fly good solid aerobatics. i also just purchased a Hobby Lobby F-86. My 1st EDF.
