30000rpm unload? never try rpm so low, i see in another post that saw boat have more than 40000rpm unload
my leopard 4082 1250kv turn well on 12s life on my fc daytona i know it's not recommended but speed is fun
i'll try with something around 38000 on 3s

thank you ^^

I would go for a Tenshock TSCZII 1540/7 3230kv on 3s.
For esc a t120.

You know you can prop up and not put such a strain on your whole system, my 47" in my signature below goes over 70 mph with 28,800 unloaded.

i'm looking for tenshock 3230kv i think it will be nice with my cc hydra 120 and i have 3s 4500mah thanks
i'm waiting for a x532 prop from china too

yes i need bigger esc and motor, i could test prop up with the 120 esc ^^
i was thinking under 30000 unloaded setup can't go at those speed
47" mono at 70mph
