Hi dear friends!

I would you like your suggestion regarding my hesitation what to chose.

I am now building a Yak-54 86", DL-50 setup. I'll use these servos: 6 x Futaba S3305 analog servos. At 6.0V they provide about 9 kg/cm of torque. It is about 130oz/in I think. I am from Bulgaria, here we use metric system. However, I hope this is ok now. I'll use a 4kg JR servo for throttle. I'll also "feed" my system with 2 x 4000mah 7.4v Li-po with normal standard connectors (Futaba style).

My receiver is Futaba R149DP. I was interested if this system will be secure and giving the necessary power to my servos without any problems for 3D flying ->

I see the connector jacks are the same, which means that I can run about 6 AMPs continuosily on both cables, coming from both batteries. I couldn't find anywhere what is the stall consumption of 3305's. I'll use dual 3305 on rudder and one on each surface (Elevators, ailerons). I read that the capability of the powersystem is 5 AMP cont. and 15 AMP momentary. Is this enough for flying hard 3D preventing all kind of failures due to lack of amperage and voltage to the servos?

If you have any other ideas or propositions about what could be used on this plane and setup, I am open to consider it and to discuss!

Waiting for your answer, dear flyers!
