As Minn..said, tou definetly want spoilerons. 10mm. up is what worked best for me. They aren't violent at all. In fact I forgot to retract them and flew the airplane from takeoff with 15mm. up on both aileron. I was trying to figure why the airplane wasn't doing the maneuvers correctly. I then looked at the transmitter and was in shock. I quickly moved the flap switch back up and the rest of the flight was better. It was OK though with the spoilerons up. If it is calm, you can land the airplane nicely without spoilerons. Add some wind and it will take off again, land again, and repeat that sequence several times. With 10 mm of spoilerons it lands like a normal airplane. With 15mm. it lands as soon as you start a flare so be ready.
