How can that be? it is geared 17 / 78 wich should be pretty low and I use standard settings and a team orion carbon lipo battery.
Is my gearing too high or is something wrong with my system or settings? 
Really would epreciate any help.
Best regards

cogging in a brushless system is caused mainly in 2 ways.
1 is as posted a sudden drop in power in when you give the gas, this from what i can gather happens more with lipos than nimh`s.
the other cause is when a sensor wire is old they seem to be less tolerante to heat than when new so when the motor is warm not hot then you give beans from the line it sees loads of power that it thinks might cause it damage so it hesitates or cogs
a new lead will sort the problem i would also check the winds in side to make sure they havnt got to hot and the laquer started to burn off.
i hope that helps i too have had a coging motor which was solved with a new sensor wire i think they start to blacken inside causing resistance which causes the problem.
