prop suggestions

[rchuntlsl]

I have run this set up through feclac. I am not real confident with the results. Hopefully some of you will have a good prop suggestion. So here is the set up.
32" cat running lipo 6s for 22.2 volts. 180 amp esc. leopard 5682 1360 kv motor.

Thanks in advance for you help.

You may want to re-think your motor/battery choice that's a WHOLE lot of motor and weight in a 32" cat. A leopard 4074, CC/Neu 1515, CC/Neu 1518 would be better options on 4s. I think your going to run into some issues with your selected power, JMO....

I myself plan on setting up a 32" cat in a few months, I plan on using a CC1518 on 4s with 45mm-47mm range of props on a Swordfish 200. I have the motor and props and have the hull selected just have to finish the 3 current projects I have in the works.

I am running on two 3s batteries right now and the boat does fine with the weight of the two battery packs.. The only thing I am changing is the motor and running the batteries in series instead. Just looking for a lot more speed. I have a feigao 6xl in it now with a x442 prop. I used to be the fastest of my friends, but they have all caught up. I need to dominate again.

I agree w/diesel that the hull is better suited for 4s, but seeing how it's working out for you I would run a prop in the 45mm range anywhere from a 445 to a 645. The motor is more than capable of larger props but may have handling issues if you go too big.

I would go with a castle/leopard 2200 and your 180 amp esc on 4s with a 45mm prop if it were me.

That motor is WAY too big. Why run such a large motor? You need a big prop to take advantage of its power. A big prop will make that small cat handle very poorly. For 6s and a Fast cat look for a 40mm dia. motor from 1400-1600 kv.
Also, are you running a 6xl with 6s?????? Not a good idea!

[rchuntlsl]

Cool thanks. I have a bunch of 3s lipos, so I am not inclined to switch to 4s. The boat has a very large rudder on in so it handles like it is on rails right now. I guess I will find out. I want to push the envelope with this one.

No, I am running two 3s packs in parallel.

So here is the set up.
32" cat running lipo 6s for 22.2 volts. 180 amp esc. leopard 5682 1360 kv motor.

Like the guys have been saying thats too much motor. Not by a little, but by alot. There are some basic rules to remember in FE. Not too small, not too large. Both have penalties that bite you at some point.

When it comes to motors you need to operate in the efficiency band best for that motor. There is no way your going to be anywhere close to the efficiency band for a 5682 leopard. That means RPM band, voltage powered and load. Your Cat is not going to be enough load even if you have the RPM band and voltage set perfectly.

The question you want to know is will your setup work? It should. I agree a CC/Neu would be a better choice. Heck,........the 1717 are still on sale for $70.

One other correction, I am currently running a y536 not an x442 prop.

[rchuntlsl]

I am going for a speed in the low 60's. The boat currently runs in the low to mid 40's (verified by gps) What set up would you recomend to do this with this boat. Since the motor I ordered is too big.

[LarrysDrifter]

An Arc 36-75-1, 1680kv on 6s with an X442 will get you mid 60's with a 32" cat.Use a 180 amp esc and two 3s 5000mah packs in series with the highest c rating.Proven set up over and over.Temps are nowhere near hot.
Or get a Leopard 4082 like Rumdog said.And you did say your running "6s for 22.2 volts".Not 3s parallel.

Would the motor be too big for a genisis cat?

Rumdogs suggestion of 1400-1600kv on 6s. I have ran 60's w/ a 1600kv (castle 1520-1y) in a 34" cat with a prather s225. Running 60's will pull a lot of current though, and I wouldnt be surprised if you find yourself flipping that 32" cat over at speed. 60+mph crashes are nothing like 40-50mph crashes. They almost always damage the boat.
I would also reccomend 2p for that kind of speed. Thats going to be heavy in a 32" cat and it might not handle that well but you should still be able to get good straight line speed.

The 5692? Yes.
