Lrp sphere with 1s lipo cogging

[SDARCY118]

Hi all

i have being racing my Mardave v12 for a while using 4cell Nimh battery with a 13.5 gm motor , lrp sphere Esc (not tc btw but don't know which one it is as there two others i belive non boost version) and no diff. which has being pretty good but i wanted to change to Lipo.

Today i brought a 1s Lipo to try it out, first off i change the cut off to nimh not lipo, but iam still have problems..

when i apply full power from stand still its never stops cogging, if i apply 50% power it dosent cog and once i built some momentum i then apply full power..is there anyway to fix this.


Cheers

Your going to need to run a voltage booster or receiver pack with the esc to provide the correct voltage to receiver to start.

Have you changed the gear ratio to suit the 1s LiPo?
What pinion, spur, tyre size are you running?

[Paulnuneaton]

Are you running 32 dp or 64 dp and like Glen said have you checked your gear ratio

[SDARCY118]

32dp no diff(though may get one soon)

gearing 46t spur and 16t pinion tyre diameter rear=47mm,front 44mm

also anyone got any experience with one of these booster seen as it only £5 from hong kong

51.36mmpr on 16/46 x 47mm

diff won't affect cogging
