New FLM Brushless Motor Mount in the Nude

Can you tell me how much weight an electric savage, with a Neu 1515 and and a 4s or 5s li-po will be??? An aproximation.....

And is my 1515 1Y, MGM 16018 and a 4s will be enough to have a decent power in a Savage?????

My XSS is suppose to arrived this week and i,am thinking to converti it with my brushless revo stock, and put the K4.6 stock savage engine back in my revo.
I want to have a more reliable tranny and diffs and i think that the Savage XSS diffs and tranny are stronger than revo ones.
