As regards the blade pitch guys there appears to be some discrepancy between punters. Some dictate 11 degrees at full throttle and 6 degrees at 50% stick. Others 6 degrees at full. What opinions? I find that at close to full power my RPM comes down, dunno if this is a week motor/batt (using the Walkera heat sinked brushless and 1800 10C batt) or too much pitch (using the around the 11 degree @ full power version).
