Leopard 3650 3900kv ?

[Andris Golts]

Hi all installed a Leopard 3650 3900 kv motor in my 22'' mono with 120 amp esc powered by 2s 5000 mah 50 c lipos in 2p format. What is the largest diameter prop this set up can safely turn?

i guess such a small boat will not like props above 37.5mm /38 mm
the 22" is in this case the limiting factor ,not your motor/esc/lipo
