Hi everyone, i am building my first drone and thinking of buying the TBS 400kv pancake motors. Only problem is that i cant find anywhere that gives the motor sizes ie 4108 or 5004 etc. It only says TBS 400kv everywhere. TBS is also not listed on ecalc to test my build out but with the motor sizes i could find a similar size motor with same kv and check results on ecalc. I did send TBS a private message a couple of days ago but no luck yet. I would also like to know if if these motors would be able to work with 4S config? Thanks in advance and happy flying all.
