I have a ergo 60 with an os 61 the problem is as it spools up there is an unbeliveable amount of torque. I think the problem may be in the blades so if figure I will ask and maybe someone will know. It should have 680mm blades however the people at Heliproz told me to run the 700mm carbon blades to get a more scale flight, would this blade change cause the exessive torque. Also the tale rotor is way sensitive, if you barely move the stick the tale will respond really quickly. I have the travel on the rudder set at 70+ 70- does anyone think that decreasing the travel will help
