What's servos perfect match for Large Electric Helis?

I like to hear from your experience about new age's Large Electric Helis.

How strong of the torque?

How fast of the servo rotate speed?

Less current when heavy loaded. Longer life span...

I know, you will expect less backlash, nicely gears fit....

Not too costy!

Boeing supply the Dream Liner. But we like to supply dream servos!



S03N3 Strong Digital MG 2BB servo had test datas just measured as below:

4.8V 0.188sec 29.0kg-cm 4000mA

6.0V 0.160sec 35.0kg-cm 4700mA

7.4V 0.134sec 42.0kg-cm 5300mA

8.4V 0.126sec 44.0kg-cm 5800mA

Guess this is the best brushed core motor standard size servo among all!

Like her sisters, she come with full CNC metal case.
