Thanks guys for your help l didn't order the arrma. I just ordered the e revo brushless edition with the DuraTrax LiPo Onyx 3S 11.1V 5000mAh 25C Soft Case Battery.
Thanks Woodie. I only have nitro rcs, l really don't trurst lipo batteries, l don't think that is save to keep them inside the house. I don't have a garage lol.
But if l use NiMh on the kraton is just plug and go, or do l have to set the esc.
