Size prop for 32" cat using Leopard 4082 1500KV with 6S?

[barryaclarke]

I am order some parts from OSE and would like to order a set of 3/16" SS props but do not know what size. I am building a 32” cat running 6S on a Leopard 4082 1500KV using .150 flex cable with a 3/16 end. I am looking mostly for the best speed without overheating everything. Any suggestions would be helpful so I do not needlessly toss money out the window……..

I use a m545 on a 2200kv on 5s about the same rpm water-cooling is a must but esc and batteries are fine

Youre better of with a .187 flex. Your .150 will last a while, but will break eventually. Ive run that set up in a 37" cat and used an X445. Speed was 62 mph on gps with temps very low. (Dont remember exact numbers).
