o.k. my Outrunner Hf iss org.4,4 KG Heavy ! By using Lipo RC Battery I will earn 100 Gramm´s less ! The 8 s /123 Li/FE Zells are only 600 Gramm´s light !
I would like to place two 4800er4s Packs into a 8 S but in the org. Hellfire there is not enough Space to Place them on a good Posizion ! I want to build a komplet Chassis, with is 3 CM longer and the Big lipos will fit in !

best Regards Stefan
