Hull recommendation - Single or Twin Catamaran?

[properchopper]

I'll place my recommendation in the Mean Machine column as do others that have built and run them if for no other reason than Aeromarine Laminates is a U.S. company that builds RACE BOATS for serious racers and will be excellent sport rigs for that very reason. Given that fact, their hulls, like the MM, are designed to excel out on the oval in racewater. (If I wanted to exercise some accurate sarcasm I'd say that the MM will run circles around the Rivercat) Sorry, OD'd on Starbucks this morning...

Here's a video posted by a customer of mine of a MM I built for him : TP Power 1515-size 2220KV motor/T-180/4S2P 65C 5000's/"El Kabongo" version M545

I can't disagree there. Different boats, different purposes. If I'm not mistaken, the mean machine is good to about 70mph? So as long as the OP is ok with that, it would be a great choice. A cheetah is also another great choice. Again, speed limited and I can speak from experience that it wants to lift off the water at speeds over 60-65mph. All the boats mentioned could be good choices, it just depends ultimately what the OP wants. And yes I picked up on your sarcasm earlier in your statement. It's ok I'm not going to feed into it.

The shocker is on the large side and I really love that hull (had one) but you'd need to run twins in that one.

Why would you say "you'd need to run twins"?

[kfxguy]

Why would you say "you'd need to run twins"?

I stated that on the fact that he has some 4074 motors he wanted to use. I wouldnt think that one of those would be all that great in a shocker as a single. We already know a shocker can run quite well as a single, just not with a leopard 4074......

[properchopper]

Why would you say "you'd need to run twins"?

He's operating from the same knowledge base that's telling a first-time builder who has a 4074 2200KV Leo, some 2S GensAce packs and will be running in large lakes that: "... If I'm not mistaken, the mean machine is good to about 70mph? So as long as the OP is ok with that, it would be a great choice...."

"... A cheetah (sic) is also another great choice." For a 4074 2200KV on 4S ? Seriously ?

"....I have a new Leopard 4074 2200kv that I was going to use in a Villain Ex conversion, but now after getting seduced by a bunch of youtube videos I'd rather use that motor in a nice cat build."

you two need to play nice ha ha ha,

obviously either you didnt read the whole thread or you just simply cannot read or comprehend. Maybe go back and read before you post your sarcasm. You know what, you seem to be hell bent on being an EDIT (hello)???, so for now on i'll just let you answer all the build questions since you seem to be all knowing. excuse my ignorance.

so a cheetah would be no good on 4s with twin 2200kv 4074 motors? hmm. ok.

i was fine with what you post initially had you left out the sarcasm that you usually throw at me. so...


here's a line from the first post because obviously you havent read it:

"I'm looking for hull recommendations (and build threads?) for a single cat and a larger twin motor cat that would be suitable for a pair of those Leopards each powered by a pair of 2s 40c 5000's (4s)."

so with me reading that I would think he has three of these motors, one for a single cat and two for a twin. so i recommended a rivercat as a single. others recommended a mean machine as a single, which i agree with also. I also stated "if I'm not mistaken a mean machine is good to about 70mph" and with that statement i left myself open for correction if need be. Then i recommended a cheetah which would run well with two of those motors on 4s each. EDIT I even agreed with you on the mm running circles around the rivercat. So from what i see, your the one who is the antagonist.

Let's keep it on the surface fellas.

Thanks

Skip to 1:07 for mean machine.
Sorry bout the music lol

That runs real nice.
Are you running 2 4s packs parallel, or 2 2s packs in series?
(It says 4s2p, but it looks pretty light, no?)

I'll place my recommendation in the Mean Machine column...

Another good running boat.

I'm really starting lean towards a boat that'll turn hard...

I stated that on the fact that he has some 4074 motors he wanted to use. I wouldnt think that one of those would be all that great in a shocker as a single. We already know a shocker can run quite well as a single, just not with a leopard 4074......

For a little clarity on the motors and how many...
I'm building one boat in this size range and I already have one motor, the 2200 kv Leopard.
They're dirt cheap right now and I'm fine with buying another for a twin motor boat if I find a one that I like enough to dump more money into.

The MM and Cheetah are my top contenders at the moment...
I'm half tempted to drop a wad on the CF Cheetah, and power it with twin Leopard 4074-2200's on 4s with cut down high pitch props?

[keithbradley]

I'm not too worried about the added complexity of a slightly larger twin, it appears to just cost more for the most part and takes more time to build.
I really like that there is no prop walk, the torque is neutralized, the cog is lower and the rudder becomes a center line unit.
Overall, it becomes more "scale" looking with twin struts.

All true.

I'm also wondering about running the 32" Rivercat on a pair of large 28mm or small 36mm motors on 6s using 3x 2s 5000's that are shared by both motors?
Is the 32" hull even capable of taking motors down in the sides? Is there good access to those areas?

I've built a couple twin powered river cats. Fitting 36mm motors is reasonable. I would run 3s per side or 4s per side though. 3x 2s is a bit of an awkward setup in this hull.

I say build a twin powered mean machine... be different!

That runs real nice.

Yeah its two 4s packs. its pretty heavy actually. i had it set up nice to run like that. it looks light, but its not. it looks like its on the edge, but its not.
