What kind of setup Bl revo

[remie]

No I've bought it frome some other guy.

Jasper is on a break with his project.

ps. what's the difference between a 8xl and 9xl?

if I use the 8xl I will have a higher topspeed and less run time?
and when I will use the 9xl I will have a lower top and longer run time?
si that correct?
