My 924 gram 6s dropped my stock motor Kraton to the left side. My 604 gram 5s did not. The 6s I have is a Turnigy heavy duty 5000 mah It's probably more like 900 grams. The 5s is from RC Juice it's 5200 mah I added some tape, shrink tube and a guard to one side of them so they may be a tad heavier. . When hanging my Kraton from the ceiling by a string.... I can see where it balances. I have a chassis stiffener rod that runs dead center. It's easy to tie a rope to it then hang it on a hook up on a floor board in my basement. My Kraton is balanced perfect but I have a larger motor, different ESC etc. let's just say.... that 6S configuration you want... will sag a stock Kraton to the one side, noticeable on jumps. My 604 5s 5200 mah from RcJuice would not. 18 min run time with 5s stock motor. 1/2 hour run time 6s with Leopard motor.(low KV long can)
I would not worry too much about it unless you go 6s... then it may be noticeable around 900 or so grams. The stock motor doesn't balance packs as well unless they are lighter. My 6s setup is how I get long run times. Low KV motor, 6s battery. It runs way more efficient. I could drop to 4000 mah and get the same 18 min run time as stock and have a lighter battery. I rather run longer and cooler. Hope that helps. Lol.
