what motor for a cf cheetah?

[kfxguy]

What motor should I run? I have a 1515 castle 2200kv and a 4082 leopard. If I need to get something bigger, let me know. I prefer castle motors. You have one you wanna sell let me know. Im not worried about esc.....ill get one that's over kill. I wanna do at least 70mph.

That will be a task with a Cheetah. The 1515 is a bit small but a 4082-92 will be good. I think the sponson mod may be necessary for over 60.

Sponson mod? What castle motor do you recommend. I don't really care for leopard motors.

The only castle motors that would work are 1518, 1520 which are hard to find or the bigger 1717 found on ebay from the traxxas xo-1 car. Nothing wrong with the leopards similair quality and performance

I was gonna suggest the same. To give you an idea, a 1518 is 82mm long and 1800kv and a 1520 is 88mm and 1500 kv.
TP has some nice motors as well, they Are my second choice.

And the sponson mod is to take that built in trim tab out of the rear step on the bottom of the ride pad.

All those motors mentioned I can't find except for the 1717 motor. Is this motor overkill?

[srislash]

Nope. It would work great. Should be able to put a decent prop on with those hulls wide as they are.
Might have to get a bit custom with a mount so it fits under the hatch. But... Nothing is impossible.

There's a ton of room in there for a 1717. I ran a 2215/1y in mine.

On the sponon. Basically the last ride pads angle of attack is too steep. It needs to be sanded flat so that it's close to parallel with the pad ahead of it. Otherwise they run like a manta ray with the nose down and the tail chasing it. Most have enough flesh in the pads to do it without adding anything in side but if it gets to thin you'll want to add some material on the interior.

I have a Cheetah that I'm working on also. I'm running a Leopard 4092 2080 and a Swordfish 240 in mine. Here are a couple of pics of what is meant by sponson mod. If you hold a straight edge on the sponsons you will see the rear sponson is not even with the first two. I started with Bondo and wound up sanding most of it off as it is Talcum power based. went with Dura Glass which is not and doesn't hold moister like Bondo does. I am then finishing with Icing to get it smooth.

Boat will be here tomorrow so ill look and see what your talking about. What if I get an x-01 speed control and convert it to water cooling? Could I run that on 5s or 6s you think with the x-01 motor?

I doubt it. Car Esc's are built for short little amp burst'. A 1717 will pull a solid 180 amps with a big wheel.

Well a mamba monster 2 like I have is rated for 120a continuous and im sure the x-01 esc is rated for more. I guess that doesnt matter tho....I can't find one. The esc im getting should handle it but ima make sure beforehand. I already have a 4082 leopard do I may try it first. Im having a feeling the castle I have is gonna do better tho. Just got my new gps in so ill do some testing sunday. Boat should be here tomorrow so ill see if I get get it together real quick and see. May have some gps issues because its a cf hull.

Ok I just looked at the TP motors for sale here on ose. They look nice. Are they as good or better than leopard? So now my choices are:

Leopard 4092
Castle 1717
Or
TP 4060 (40mm x 92mm)

Which motor you think and what kv to run 6s?

[srislash]

I would go with the TP around 1600kv give or take.
