I won't give it a try, I am happy with my LiPo-powered SP for now, a possible replacement would be a -again- LiPo Cat SX... In case LiPo will be legal in Germany next year for official races, I might race in the Stock class with a 13.5 T BL motor, probably with the new Hot Bodies 2WD...
To put it short: no saddle packs for me anymore! (except in a S500 or BMax4 maybe
)
