[steinersamuel]

Im building my first twin cat! I've got a carbon fiber fightercat Daytona. going with two leopard 3674 2650's, two t-180's on 4s per bank. I'm looking at the cnc props fightercat offers. the 5018 3 blades seemed rite, but don't have money to waist. If anyone can advise I sure would appreciate it!

Sam,
I ran 2 cr x442 S/B props by Dasbotas on my E kos with smaller 28 can motors and got high 50's out of it on 4s.

They were 2 blade tho..

I bought a pair of octura x442's and a pair of x447's!
Are the 447's going to be too much??
I bear a lot of people running singles with similar motor batt combos with great results.

You just have to keep an I on temps of motor,batt and esc. A few full throttle blasts and bring it in and shoot them with temp gun.

Run times will be shorter also.

I am running a Daytona twin on 3659 EDF motors from HK. They are 1900 kv. I am running them on 6s. I know you are running on 4s, but this is just to give you an Idea. Im using T180's. I am spinning Octura 447's and the boat will run almost 80 mph. My buddy has the exact same set up but is running ABC cut down props. I think they were 50mm that he cut down to 45mm. His boat ran 89 mph last outing. Both boats will come in after a 2-4 minute run and nothing in the boats are over 120 degrees.

I also run a apparition twin. it has 2881 kv 29mm motors in it. I run it on 4s 5000's and CNC 442's. runs in the low 60 mph range and everything is around 115 degrees after running a 3-5 minutes.

Conclusion---I would think that the 447's should be fine. If you are worried start with the 442's and then prob up.

Then I would start off with a 442 then 445 and probably end up at 447. run one and check temps. I like to keep mine under 120 degrees on everything. At 120 degrees you are pushing everything quite a bit but not to the max. I'm assuming you are still running it on 4s.
