Alright i bought a used mamba max 7700 on ebay and ran it in my old t2 for a while on 8 realy old cheap 3000mah cells. It ran pretty good(considering the batts) Just recently i bought a new emaxx(planning on going brushless. So i sold the "waterproof" esc on ebay. i put in the mamba and am just running the twin titans in parallel. and 12 old 3300 cells. and a reciever pack(yes i desabled the internal bec) Okay. But heres the problem. When i plug everything in it arms everything seems to work runs like stink. and then a few min. later. It just shutsdown. If i didnt know better i would think its thermaling. But the heatsink doesnt even get warm. the motors dontget warm heck the batts dont even get a chance to get warm.(its in the mid 40s here) Anyone know whats going on. the next day ill plug everything in and it will work. I dont have a prob. sending this in if its broken. (Idont want to wait 2-3 weeks but i will if i need to) I Want to get a 9xl but i dont want to get it only to keep having this prob. Plus i would like to run 14 cells. and i have read that the new esc's that castle sends out(for repairs) wont run them. So what should i do?
