This is 100% a cogging issue and is usually caused by getting a motor with too high a KV rating. Higher KV = higher speeds, but also equals less torque. I tried converting my Bugsta to brushless and put in a 4300kv motor using the original 17t pinion. On 2s I pretty much had to kick it to get it moving but bloody hell was it fast. Too fast in my opinion. After trying 3 different motors, 4300kv, 3300kv and 2200kv and numerous different pinions I have now got a setup I like. I now have a 2200KV motor, with a 15t pinion, 5000mah 45c lipo, which in a race with my brothers car is exactly the same top speed as a "standard" brushless bugsta, and I would say 25-50% faster than a "standard" brushed Bugsta. It is really drivable with minimal cogging. If I want to go faster I put my 3s lipo in and get 50% more speed (till I hit something). I hope that helps when people are trying to find a decent brushless setup as I had a lot of pain to get to where I am today
