will a T180 handle a leopard 4074 2200kv on 6s ?

[Jcarlton]

im geting into my skunk works cat 32 . i was thinking of running my leopard 4074 2200kv on 6s with a T180 speedo and a x447 prop. do yall think it can handle it ? any input would be greatly appreciated .

That hull, with that KV, with that prop, and with that ESC, on 6s? My input is, ----- NOPE!

[Jcarlton]

any suggestions for the T180 . motor size ? kv? prop ?

The hull, motor, KV, and the T180 are all fine, for a smaller prop on 4s, or maybe even 5s. I would start with a 40mm, 42mm on 4s, and check temps.

ok great ill start there .... thanks for your help

I ran a "similar" setup at the SAWs a few years ago....Skunkworks cat, Castle 1515/2200, Castle 240 amp ESC, Prather 235 prop. It made passes over 90 mph pulling around 250 amps. I only made two passes each time and pulled it in as ESC temps were getting high.

The x447 is a little less aggressive than the P235, but it will still pull too many amps. Run time will be limited regardless. As above, 4S or 5S would be safer, as would an x440 prop.

Personally I think if you propped down to either an x440 or an x442 you would be fine. However as previously mentioned however either lower voltage or lower kv would be a safer setup.

I know you already have the motor, so if you must stick with that motor, here's a good recommendation:

Sport run it on 4s with a x445, x545 or abc 1715 or 1814 prop. Will be in the 50's and won't break a sweat. Will likly be close to 60 with the abc prop. You could go to 5s for short bursts. If you must run 6s then start with an x442 or x642 or a abc 1615 or 1715 for short bursts. Check your temps. I do not recommend this high of kv on 6s for any amount of time over a few seconds at a time. Add a cap bank. With an abc 1715 on 4s I had a similar hull going 63-64 on 4s. So to have fun you really don't need a lot of voltage.

Now for the correct 6s setup that will last you a long time it'd recommend a motor swap. 1700-1800ish kv, 4082 leopard, tp 4060 or neu 1518 or 1521. My choice with cost involved would be the 4060 tp. Beast of a motor for the price.

Right now I'm tweaking in a 32" cat on 4s that's bested almost 96mph with barely more kv than what your running. You don't have to run 6s to go fast I've come to figure out.

thanks for all the input fellas!!!.......love this site

ordered x440,442,and 445 props . will test like y'all say and check the temps . might look into some other motors as well .

Well to be honest I'm not much of a leopard fan, I know your not asking that, but I suppose that motor is a bit overkill for that hull. It's quite long (92mm) so you have to ba careful of your mounting. I have a brande new 1720kv tp 4060
That I could make you a deal on with the water jacket of course if your interested. I prefer tp over leopard. He build quality of their rotors and stators look a bit better and they put out lots of power for their price. Pm me if your interested in the 4060

dang wish i knew that before i pulled the trigger on ebay . will keep you in mind if it doesnt work out . just started tearing the catamaran down for a sick john deere racing theme . will post pics as i get into the build . thanks again for all your help kfx ...... also love your fightercat vids..... damn that thing is fast !!

if your going to run that high of a kv i would definitely stay away from the x series props. they wreaked havoc on any of my setups over 1700kv, currently im running a 3659 can on 6s with a M440 the M series is basically octouras detounged or "unloaded" series of props. not only did the X series give my cat too much bow lift and make it more of an airplane but it also pulled way to many amps. out of the hole the x440/x442/x642 were quick but on top they could just not compare to the M especially with my setup
