RE: eagle 50 helicopter
I would definitely suggest you invest in a simulator. xheli sells one. Don't fly your eagle 50 until you can fly the simulator proficiently with the tail in, and then you NEED to master head in. Why? Because then you will be prepared for just about orientation your bird may take and correct accordingly. When flying heli, there is little time to think. You just have to DO, and that comes from knowing. If you are nervous, go back to the simulator.
As far as setting up a heli with a pitch is concerned and the mechanics within, there are tons of threads and articles in these forums with alot of really good smart advice. Believe me, take your time in research by reading, practicing the simulator, and testing your copter with training gear on. When you get comfy and the bird is trimmed out, take the training gear off and fly it. It has taken me a couple months to get to where I am now and it takes discipline. I am no pro, but I can fly circuits and fig.8 because I took it slow and I have only been doing heli's for 3 months. Resisting temptation to fly when its a bit too windy outside or the heli is not tuned just right is important. You need to get to where you just won't crash.
I have had alot of succesful flights on my Eagle 50 and I burned out my main motor in a month too. It happens. You only really hear about the guys who's motors have burnt out on these forums. Of course I doubt anyone is breaking the 100,000 mile mark on the 370SD either.
If you are gonna try doing custom electronics upgrades like brushless for your eagle 50 you should maybe read up and see what others have suceeded and failed at before you go burning up expensive components. It sounds to me like you are a bit excited which is perfectly fine my friend, but breathe a little and be patient. Do your homework first. You will get alot more satisfaction out of the hobby when you can fly without nerves and keep the bird in the air for the whole battey, and land safely with NO DAMAGE.
You will get there.
