HELP NEEDED - losi xx4 lipo stick conversion

[David W]

I am wanting to run lipo stick in a losi xx4. I have built a second car with a solid chassis and want to run stick packs. I have tried them in and they seen to fit quite snug and a bit tight to get in.

Has anyone got any advice and pics of theres.

Could do with finding out what is best for holding in the lipo and if any triming of the chassis is needed? Also does the car need balancing with weight?

Thanks!
