could be batteries too if they are having trouble holding voltage then the current spikes higher. I dont think higher timing is the answer though.

My lipos are good. They are holding up. They aren't even breaking a sweat with the current drawn by the motor. The peak only increased that much after I've switched over to a HW80A. I don't see any decline in motor power. On the contrary, my e-savage seems to be running faster. Batt runtime is lower though.
One thing I've realised is that my feigao 5407L 3511kv at 4s is rotating at almost 52k rpm. But it has been holding up for the past 6 mths or so. The power seems to be as good as new. Maybe I've got a good one? The motor temp used to be around 80C. But after a chassis mod, the temp dropped to 61C. The entire chassis now acts as a heatsink for the motor which explains the the drop in motor temp. And oh the chassis + GP arms mod did increase the weight of my e-savage by close to 200g. It now weighs slightly above 4.1Kg. But a mere 200g increment in weight shouldn't be seeing a 50% increase in peak current right?
