Allright, went to the hobbyshop to buy a Tensor 4d today. What do you know they didn't have anything I wanted (except the motor) I could have bought a battery and charger but I figured I should wait and see what people recommend. So then, what battery is the optimal one for 3d flying with the Tensor? I would prefer to know beforehand just in case they decide to try and talk me into something more expensive.

Let us know what motor, recommended AUW(all up weight) and whether you are going to fly indoors or outdoors.

OK, I'm using a 370 outrunner, weight recommended to be around 12oz, planning to fly outdoors.

I use a 2 cell 1100Mah 8c 15c burst from XUS HOBBY on ebay. Just do a search for li poly. I have 6 packs now that I picked up from $17 - $20. I get 10 minutes of 3D flying with the PARk 370. There are two 370 motors though one is for two cell and the other for 3 cell. If you get the one for 3 cell that have these batteries too for 1/3 more the price. Although the discharge rate is only 8C the packs barely get warm after 10 minutes adn haev all the power you could want.

3S, i like the kokam 640s best as there light, however olyquest 880mAhs are awesome too
