(I learned this from a very experienced flash pilot who was not having any issues.) Once I got into that routine, I never had another issue with snapping or landing approaches. I do tend to still come in fast as I too am still a bit nerve wracked from the past snaps. I am sure keeping the speed up helps too. But, staying off the rudder helped me the most. After coming in fast, then there is a lot of braking to do. One needs a good brake controller to maintain control, especially with electric brakes. I have tried 4 different E-controllers and currently am about to test the LG15 on the next flight. It seems to be the only one that works well enough to avoid brake dancing.
Cheetahs are great engines. The only thing that I have seen come up with our jet guys that use them is the brushless starter upgrades use a lot of battery. Not sure if the new ones have that solved or not. Have only seen a couple come back from their routine service with the brushless starter upgrade and the owners were really POed cause they could only get two flights off their batteries that used to give them 5 flights before the upgrade. Other than that they seen to be great turbines with lots of power. Very reliable in starts too.
That is not normal. Typical consumption with the brushless starter is not different. My cheetahs and Rhinos are in the 450 mah per flight, so I do 6 flights per charge on a 3800mah battery. Talk to Manny about your problem, something weird is going on if you are using over a 1500mahs per flight. Maybea some huge restriction on your fuel system?
what battery are you using?
