My Brushless 8ight Project

[mxracer]

i have 2 brand new truggies , no binding , everything smooth as silk

got 7 x 4s flight power 4900 packs (so that rules out a dud pack)

1 truggy is MM 1515 1Y geared 13/52 motor temp 50deg C
other truggy MM 1512 2.5d geared 14/52 motor temp 70 deg C

both get 10 mins runtime

then i tried the 1512 2.5d on 5s with 12/52 and still 10 mins . with no extra speed and motor temp 70 deg C
