Octura prop size for 32" cat

[Tony]

Hi guys,
I'm running an Octura x642 prop with a 9xl motor, and a 125amp esc. Will these props work for my setup as well? BTW, these are all Steven has in stock at the moment.

I assume you are running 4S. Those props will work - if you want to go slower. All have less pitch and/or less diameter than the x642. I run m445, m545 and m645 props on my MeanMachine with that motor on 4S and the cat runs great. The motor will handle more prop than the x642 - but as always watch for heat issues as the ESC may get stressed. The boat must be running freely, not too wet.

Once in awhile i run 6S, but most of the times 4S. You hit it right on the nail. I am having heat issues. This is the reason i was thinking of going to smaller prop. You mention the 9xl can handle more prop than the x642. So, do i prop up or down?

Fluid will most likely Jump my back for asking but how long are your run times? That will play a part in your heat. If running 4S with the 642 prop for say 4 minutes you should not see to much heat. Also, Is your strut adjustable? If running to deep of a strut it will add unneeded amperage.

I know these are "SILLY" questions and statements but fluid can still kiss my prop nuts.

My run times are around 4-5 min for ZippyFlightmax 2x 2s1p 7.4v 4000mAh 25C in series. Strut is adjustable. I ran the boat this morning with the strut down, and the motor, batt dean plugs were hotter than normal. I'm going to raise the strut up a lil, and try again this evening.

Why the attitude? Why would I "Jump" you - are you a hottie? Do other guys jump you often? Lose the attitude dude.

Sir, you have already made one very inflamatory remark in a previous thread towards to Fluid " And this is why HAY T. IS BANNED ON RRR! HA! I would love to kick your ass ya queer. So tough behind a computer. I imagine you got your ass whooped upon daily in school didnt you? This isnt YOUR forum there jackass. Dick"

and now you make another one. I for one do not want lose Fluid's insight to this hobby because of remarks you have posted. Bye the way he is not banned on RRR.
Now back to the thread

Oh, come on Douggie. Relax. I think Fluid has some pretty thick skin. Was I wrong in posting what I did? That is the question. Did you play any part in helping the O.P.er? I am curious if anything helped. Especially if it is a vemon boat he is running. I dont think I was in the wrong when Jay jumped my statement about the other thread. And Finally yes, he was banned. I dont lie.

Ok. So while you guys are at it.... I raised the prop up a lil, shorten the y series lipo connector about an inch... Ran the boat about 5min. Everything seems cool to the touch, accept the motor, which still abit hot to the touch.

[Boatman]

I personally have never had a Feigao run cool after a run that long. I am assuming that is what your running 9xl. Usually 4 minutes is the longest I run before bringing it in for a cool down and battery change. Also Getting rid of the deans connectors will reduce even more resistance and switch to some 5.5mm bullets. How was your speed?

Yea. Its a 9xl motor. I am using 5.5mm bullets betwwen the esc and the Y connector end. Only from the lipos to the Y ends are deans connectors. I am getting some 4mm bullets to replace the deans. Will these work with the 5.5mm bullets?

I haven't check the speed yet. But, she flies.
