Good point mark but.......
Can you take someones eye out with a lipo from 30 yards?
I like the idea of lipo for next year, people say it will be cheaper but in reality we know it wont be as we all know we will have at least 2 packs.
I did try one briefly though and it made the car feel so much more nimble and nicer all round, the hardest part was keeping the front wheels on the floor.
