what mah lipos are people using?
 

ive got an rc8be and just need to get some lipos for it now what sort would be best? ive got 2 reedy 5500 60c 2cell packs i was going to put in it but wasnt shore how long they would last. i need to be geting 15 mins of run time would these do it? i run a tekin rx8 speedo and a tekin 2000kv motor and dirt and astro tracks.

losi8e 6 cell 1400kv, 30 mins on 4500kv 30c with about 4000mah used, i am not very throttle happy though

Assuming good gearing, and careful throttle application (no blipping, smooth on/off and rarely use full throttle as it's not needed), 5500mAh is easily enough for a 15 minute race (including the last lap basically).

mbx6 eco 4 cell hobbywing ezrun 150 tekin 1900kv, intellect 6800mah got 22 mins on 16/46 at herts yesterday

Losi EU E
 

Losi 45/15 gearing, Hobbywing 80amp ESC & 1965kv HPI Motor running with 4s 6000mah NanoTech lipos - 22 minutes runtime.
Was running a Monster Mamba & 2200kv motor & getting just over 20 minutes runtime.

Tekin 1900 using either Gens Ace 5800 45c, or Vampire 6200 70c (my arse)Would be fine for 15 mins,2/2s Serpent Cobra

1900kv 2x2s 4s total, 4000mah nanotech 12min runtime

went 6s, 2x 3s 2200mah. I only need to make 10 min in my area.
