| I just put a BLS 251 on the tail. I'm using a GY611 to drive it. I went with brushless because:
1) No brushes. I know, your thinking Duh, this guys a rocket scientist but,..... The real issue is arcing. Get rid of the brushess get rid of the arcing. Now, you should be able to get the gain a little higher with out frying the servo, inducing hunting due to the servo.
2)Power. We use brushless motors in our helis, because... they are more powerful than comparable brushed???? Yes? No? I'm going with yes. Anyway, I think that these servos are under-rated. I attempted to turn the servo arm on the BLS251 with the power on, and the heli moved. It felt more solid than any servo that I have ever run. And it didn't make that humming sound that all of my other servos make when you move the stick while attempting to hold the servo horn.
3)Longevity. I have had motors burn out on servos, well before their time. Tail servos are a prime example. I have had three tail servos burn out, and that was before I could spell "three dee".With more and more servos being driven directly through an electronic device of some sort and not the stick on the transmitter. The speed of these servos are actually getting a workout. You have governers on your throttle, gyro on your tail, and now flybarless on your swash.
On the other hand, there is leading edge and bleeding edge. That would be bleeding with two $$! And only time will tell.
I'd rather be flying |
