8711

Is an absolute Amp hungry servo and is overkill on many of todays Jets.

I use it on my Giant Scale Acrobatic planes that have extreme control deflection.

The 8711 is also only slightly heavier then the 8611a. Don't get me wrong both are the best but you should make sure u have an electrical system that can handle the 8711 should u max amp her.

Typical LG style Battery from Fromeco and TBM are good for a 10 amp draw per battery.
