Hello all,

When I take off with my HPI RS4 Evo, sometimes it will begin revving (get to about 1/3-1/2 revs) then suddenly cut out for a split second, nearly stalling, before revving back up. This was happening a bit at the track yesterday and I couldnt quite figure out what I was tuning wrong.

Anyone know what about my tune is off? My guess is LSN too rich - clarification anyone? Thanks heaps.
