Sorry for the late notice but it looks like hobbyking is having a flash sale (available for the next few hours) on KEDA 63-64 190KV motors for ~$36.3 USD. These appear to be a nock off of ‘hacker’ branded motors, but are likely of a lower build quality. However, with a ‘rated’ maximum current of 90A and 190kv they appear to be your best ‘torque-for-your-dollar’ to be found at the moment. Stock is still available in the Australia warehouse.
Anyway, if your looking to pick up a motor for the next o-drive batch this could be worth a look.
