Klims, if ya haven’t already, rig up some sort of proper battery charging system.
Not only will you dramatically increase your run times, but with a good charge the cell/s will reach a higher voltage so you can go faster.
Oh, did I mention to do the FET mod too ? 😛
keep an eye on this guy for ZZSE and xmods – only 1 item up currently, but I got my ZZSE for US$10.. and the XMOD he has up now looks cheaper than most.
