And that is not that important to me either,seing how I am on the straight about 3 sec on a 28 sec lap,but want great eff. to get the runtimes.
With my buggy,on 4s it is good on the track,at first was all i could handle,but after running the buggy on 5s now and getting some good throttle control,I will never run 4s in the buggy again.
I am thinking I may be running 5s only and possibly with next batt purchase getting the 6s tp or fp packs.
So I will have to decide between the 2d or 2.5d then it looks like.
