Quick setup questions...

[Naushad]

Just want some up-to-date opinions here...

I've rebuilt my kyosho fs. It has a orca 7.5 t with 21 pinion for stock spur. I have also installed a ko propo servo and a ko propo speedo.

Now...

1) the back end swings out. I already have a roll bar installed only on the rear. Do I need to add weight? If so, roughly how much?

2) have you guys got any tips to ensure lipos are snug in the compartments? I'm using intellect lipos.
