KNPC's 43'' Conquest build

[knpc]

I'm starting a new cat biuld. The hull is a 43'' Aeromarine Conquest with an Avernger hatch. I have almost all the components for the build, just waiting on the motor which has been ordered. I've been able to do a few things, mostly planning at this point. Just about everything for this build was bought from OSE and forum members.

This is the plan so far
- 43'' Aeromarine Conquest hull reinforced with CF
- Speedmaster strut w/ skeg
- Speedmaster rudder
- .250 flex stepped down to 3/16
- CC Hydra 240 HV
- Neu 2230/1y (725kv)
- 10s2p 35c lipos (four 5s 5000mah packs per run)
- motor mount from Peter Zicka
- 8mm-.250 coupler from Jeff Wolt
- decals from monojeff
- prop?

Here are a few pictures. This is by far the biggest hull I've built, everything to this point has been 4s or 6s setups.

I'm open to any setup suggestions you guys may have, like I said this is my first BIG cat. A couple questions to start with. As far as c.o.g. I was thinking to set in around 33% with room to adjust forward and back 1'' or so. Also what props should I try, would a X460 be a good place to start?

U running twins or a single?Oh duh a single. I see the mount. that 2230 is a beast when It moves a mono with a prop that size @ 70 plus mph I think that 2230 will chew that 460 up and spit it back out at you lol hell yeah try it. But I bet It can do more.

Single motor, one big Neu. I'm not looking to break any records, my goal is for it to run mid to high 60s, maybe 70 and stable.

Aww sh.. 70 will be cake I bet for a big Neu.

Forget about the boat, your kid is adorable. That being said, that setup will fly. You may need more than 33% C/G with the speeds you are going to hit. I just built my 1st cat as well. An Aeromarine Cyclone. Certainly two different approaches to a build. I wish I got one of Peter's motor mount esc setups, it is truley a work of art. The best of luck, and enjoy the build. I will be following your build.

An x462 or x465 are pretty standard for that motor and hull. Depending on the use you could go up a bit like an x665. That was a bit too much for the Lehner 3060 in my Stryker cat but your big Neu should eat it up. I like the Avenger Pro hatch on this hull.

The conquest is a fantastic boat! Hands down one of the best handling boats I ever built and ran in that length. I ran a pro mod zenoah with these props http://www.voodoopropellers.com/ Having said that, I don't know if they can be used with an electric setup but I do remember running close to 70 with these prop's and handling really well. (I don't remember which one's, it's been a few years) perhaps someone else here might have experience with voodoo props??

It's nice to have some options I guess..

Thanks. It's our first. she is almost 3 months old and is such a great baby. I thought it was an interesting size camparison and snapped a picture.

I've been watching your Cyclone build. It came out real nice, paint is great too. Looking foward to a video


Thanks for the prop advise Jay, I'll give the x462 and x465 a try and go from there. I like this hatch much more than the stock one as well, completely changes the look of the boat IMO.

First of all, congratulations on your baby! May she outgrow the conquest real soon.

According to my cat speed formula, the speed ranges for the following props are:

x462 ~ 63mph
x465 ~ 66mph
x468 ~ 68mph
x665 ~ 75mph

I am all done with small boats as for the past year, I've been contemplating on a Conquest 43in build. I've got more 6S than 4S setups, and it would be nice to go with 12S in that hull. I wonder if the 725 kV would be too high for 12S as the 485 kV sounds too low?...

In any case, I'd love to see how it turns out, maybe you'll have it done this summer?! Keep us posted.

Looks like the King of the pond is building his defense !! Caileigh could ride in that thing, she is so small, 1/12 scale human?

No challenging anyones expertise but weve yet to see a GAS prop as effective in an FE as they run in a different rpm range. Fluid has already told us this and I honestly cant remember seeing a gas prop run good . So i got to agree with him.Nothings impossible I know but stick to the octuras in the 55-65 mm range. ABC makes some good props too.

I've been running the big Neus for several years now and this is my take on it. In my mono I ran 12s and all sorts of 3 and 4 blade props in the 65 to 70 mm range from voodoo and prop shop and the motor handled all of them. What it comes down to is finding the right prop that the boat likes. For my mono it was a 6515 or 6715 prop shop prop with a little work done to be more mono friendly. I would figure out what prop the gas guys like running with that boat and start there. An X465 or 467 wont work that motor very hard on 10s. I agree most electric motors dont like gas props but the 2230 has no problem with them.
