Step up from X443, X642, M445 or X445?

[Mattwarner]

Hi I have a FC Daytona (carbon) with the following set up:

Leopard 4082 1600kv
T180 esc
6s1p

I have some neat cooling mods and being in the UK the water is always freezing! I currently use an X443 and temps are so low I can hardly tell its been run.

I want to try a slightly bigger prop but not sure what I should go for? doing various searches I've seen people have good results with the M445 and X642 but given I am running a 43mm prop with little heat issues should I step up to something like an X445?

Thanks

m445 is a great prop for that set up.....i have a p mono with t180 4074 leopard and m445....i could run bigger but its running 47mph all ready

A 4082 1600kv will spin a M645 without much hassle. You might wanna go 2p on the Lipos for that tho, as the motor will suck some current. I have the exact same motor & esc combo and I run a 646/3 (on 6s2p 5000 mah, 25c). Motor is STILL cold but the esc is getting warm. Definitely not hot, but warm. Haven't run it enough to give any final judgements on what it can handle. If you think water is cold in England you're welcome to Sweden and check the temperatures out :)

M-props are better for speed, especially on your light hull. You don't need the bigger tounges (which is what differs M from X).

Thanks guys, i think i will go for the M445 seems to be a good choice for many on here.

Im also running a M445 on my CF Daytona and the temps are in the low 90-91 degrees on esc and motor. Lipos are only luke warm running two 45c 5000 3s in series
