Hi,
I have 2 L700's
1/ KOSMIK 160 - SCORPION4525-520
2/ KOSMIK 200 - PYRO750-50L2Competition
Both heli's are equal in weight and setup. LOGO717VTX 13T pinion flying at 1840-1940 RPM
Both motors are performing very well. Where the 1ste heli has about 20s more fligthtime, the second has little more power. However, the power differency is hardly noticable in my case flying F3N setmanoeuvres and freestyle. The PYRO competition seems to have a slight wider power curve, which means I feel the torque is more equal through the manoeuvres. The most spectacular noticable difference is the temperature after landing. The Scoripion is ALWAYS way hotter then the Pyro. However, I have to say my Scorpion 4525-520LE is 4 years old, replaced bearings twice (preventive ) and has at least 500 flights on the counter, which makes it a very reliable motor to me and a very good choice for the LOGO700. The Pyro competition on the other side is mechanical jewel, which comes at its price... :-)
