Alright, so I finally got sick of my single cylinder gas engine rattling the crap out of my airframe and being really annoying sounding in the air and came to terms with an electric conversion. The plane I will be converting is a 33% sd models yak. I have learned a little bit of the basics towards large electrics but still have alot of questions and I dont want to blow the money on the wrong stuff. So the idea I had towards the equipment goes like this. As far as the motor goes I know I am gona get the A80 hacker, but i'm not sure wether to get the A80-10 or the A80-8. I have already bought a 160 hv esc so that is for sure. But in the battery department I still need some help, I know that what I choose will have an either good or bad effect on the esc, so heres the question. I know the batteries will be 5000mah, but what would be the best for my setup as far as 5s or 6s, and either 30c discharge or 40c. Once again, I have no idea what I am doing so explanations would be well appreciated, thanks in advance guys.
