G10 V3 8,5T motor for 79,99$US. Not bad... Kind of Surpass motor price.
note: I am still looking for Surpass 8,5T or 10,5T motor... I mean, the low output ampere is interesting for a 10,5T 4900 kv (63a). But what about the overall efficiency...? And all the heat after 5 minutes... I am around 90 Celcius at the end of 5 minutes with my actual G10 V3. (cut off at 105 Celcius)
