Sctcrash,

I am using all standard servos and battery packs on my set up. I have had no issues yet, they might come down the road, we will see. I can tell you that I am thinking of getting the battery pack upgrade and all digital servos as I move forward. I think the torque and the response will make the 3d thing a tone easier, but it is pricey.

Good luck on you're build.

Tom
