Default HOR Racing 32" cat

Hi all

I've decided I want to setup a new boat (more or less from scratch). I really like the look of the HOR Racing 32" cat (http://www.horracing.com/product_inf...products_id=99) - does anyone have any experience with this boat?

I think I'll go for a single motor/prop setup.

I figure I'll need:
- A motor
- An ESC
- Batteries

A stringer driver with cable (http://www.horracing.com/product_inf...roducts_id=318)
A rudder (http://www.horracing.com/product_inf...roducts_id=205)
Trim tabs (http://www.horracing.com/product_inf...products_id=35)
Turn fins (http://www.horracing.com/product_inf...products_id=32)
A propeller (any suggestions?)

Basically, I'd like everything I need to make a good fast boat, and I'd like to do as much building as possible.

Thanks for any input or comments

Andrew

You don't need trim tabs or turn fins for a Catamaran. Are you sure you don;t mean the 32" Pursuit Mono hull?

His hulls are very nice, well made compared to some other Asian hulls.

Please clarify your intentions.

Hi BackEMF - thanks for your reply.

I'm only just entering the world of fast electric boats - thanks for clarifying that trim tabs and turn fins aren't needed.

Regarding the strut/shaft, am I right in thinking that that strut it too short for a single prob on a cat? Would I be better off with a strut/rudder combination that is specifically deisgned for a cat of this size?

Thanks!

Many have built that hull. Really depends on your budget for electrics. You can go all top end or lean towards a more budget build. I did a twin verison of that hull for rather cheap. I called her el cheapo lol. She was pushing 60mph on $40 worth of motors lol.

It really depends on what your expectations are for this project. You want ALL out speed or a milder more enjoyable sport setup that is more reliable. I like milder sport setups my self. Decent speed, decent runtime and relaible. Some guys get so fixed on going so freaking fast it clouds there judgement. When you start speed chasing your very rarely satisfied.

Hi Diesel6401

I get most of my enjoyment out of building, painting and getting it ready - I'm really not that bothered about getting all out speed.

Do you have details of your build anywhere? I would really appriciate knowing what motors, struts, rudders and shafts you went with. I would prefer to make a dual setup over a single one, but I was put off by the additional cost. However, if it's only a bit more, I might still go for it.

Looking forward to your reply!

Andrew

OK - I've decided that I'm going to buy that 32" cat.

I'm going to go with a single prop, to keep costs to a minimum.

The only thing I'm unsure about is which strut to get - do I need an especially long strut if it is going in the middle of a cat?

Would http://www.horracing.com/product_inf...roducts_id=335 be OK?

What sort of size motor would you recommend for this sort of boat?

The twin I made was really only good in the straight, it dogged in the turns because the batts had to be centered in the middle of the hull. For better turning the boat would run better as a single motor with the batts in the sponsons. should run awesome that way. Just my 2 cents. the twin setup i ran was:
2 seaking 80amp HV esc's wired in parallel
2 suppo 3126 1600kv outrunners
2 3s 6000mah 25-50c nano-techs in series for 6s1p

I ran the hor stingers that i converted to 3/16



If you want a nice reliable setup Ihave been running a leopard 4074 1774kv motor in a 29" cat and been LOVINGIT. Has been my favorite leopard motor to date. Add a swordfish 200 which is slowly becoming my favorite esc and you will have a winner JMO... Prop something like s220, m445 or a m645 (I am currently running a modded x447) and you should have a nice setup. Ithink the m445 would be better though, mild prop for this setup that should yield low temps good runtime and decent speed while keeping stress on the system low. JMO

Thanks for that, Diesel6401. I'm thinking about using the Leopard 4074 2000kv motor (probably on four cells) - I've found a pretty cheap seller of them ($85 inc P&P).

So I just need to decide what parts to order from HOR, so far I've got:
A Hull (32" cat) http://www.horracing.com/product_inf...products_id=99
A motor mount http://www.horracing.com/product_inf...roducts_id=388
A strut/rudder/4mm flex shaft combo http://www.horracing.com/product_inf...roducts_id=335
5mm motor - 4mm flex shaft coupler http://www.horracing.com/product_inf...roducts_id=149
Pushrod http://www.horracing.com/product_inf...roducts_id=200
Pushrod boot http://www.horracing.com/product_inf...roducts_id=201
Bronze prop (almost the same as an x447, but cheaper) http://www.horracing.com/product_inf...roducts_id=366
Flush water pickup http://www.horracing.com/product_inf...roducts_id=184
Small water outlet http://www.horracing.com/product_inf...roducts_id=177
Silicone tubing http://www.horracing.com/product_inf...roducts_id=107
Bulkhead nipple http://www.horracing.com/product_inf...roducts_id=183

And from elsewhere:

A cooling jacket
A 120A ESC (Turnigy)
4mm to 3/16" shaft sleeve
A Leopard 4074 2000kv motor

Is this list OK? And is the strut/rudder I picked long enough and suitable for a cat? I've already got radio gear and batteries.

Thanks again.
Andrew

What you have picked will work just great!

He does sell a 4074 2200kv motor that is very nice too.

The only thing that you may want to change in future is the drive cable.

The one you get from HOR is a captive square drive that you either remove t he motor to lube the shaft or remove the strut. Both are a bit of a PAIN.

The strut is fine to start with but, you may want to convert the strut/rudder to a 3/16" american standard drive shaft that can be removed from the rear by loosening the flex collet. This way you don't need to remove screws or re-position your strut after each Re-lube.

You must re-lube every day out.

You will need 2 Octura Lead Teflon bushings, drills & a .150 flrx cable, preferably Hughey cable or this guy on ebay has great flex cables.

OR, just get the modified strut assembly from OSE instead... : http://www.offshoreelectrics.com/pro...prod=ose-80085

Thanks BACKEMF. I think I'll start with HOR's cheap strut and rudder, and move up to OSE's modified one if I find HOR's too much of a pain. 4mm is standard for flex shafts in Europe, so that's not too much of a problem.

The 5mm - 4mm coupler I linked to is off collet design, so it would be possible to remove the flex shaft by just loosening that - I guess I'll find out when the stuff arrives.

The Leopard 4074 is available as a 2000kv or a 2200kv - which would you recommend?

On four cells (14.8v):
2000kv = 29,600rpm
2200kv = 31,680rpm

Is the 2200kv going to be going too fast? I'm currently thinking about going with the 2000kv motor.

Many thanks again
Andrew

Just to let people know, the cost of all the items from HOR:
$191 without postage
$237 with postage

I'm very happy with that price - I feel that $237 is pretty good for a complete hull with all drive hardware - only the electronics are required seperatly.

If anyone can see any ommisions or incompatible parts on my list, please let me know! Otherwise, I'll put in the order in the morning.

For that propeller, the 2000Kv is better for starting out.

Johnny, HOR, has great stuff at great prices.

There are some really cool original hardware pieces on his site.

I'm waiting for my 32" Pursuit mono to come. Very excited to see it.

Another question:

I've found an almost identical hull on ebay: http://cgi.ebay.co.uk/32-3-EP-Fibreg...item3360830c89

The price works out to be exactly the same once postage is factored in. The hull looks to be a relitivly similar moulding.

I'd rather have a yellow and black hull than a plain white one - are there any disadvantages to getting the 'unknown' hull from ebay? Would you recommend sticking with HOR, or is this ebay one OK?

Actually, it seems that the hulls might not be stepped quie as much - maybe it would be a big hurt to performance to go with this unknown one...

Thanks!

Hi Andrew ,

It has been stated on another forum , that the hull your considering is less desirable over the Apparition hull , due to its quailty of glass work - i may be wrong , but i'm sure this is the case .....

All the best ,
Brad

Thanks Brad - that doesn't surprise me. I'm sure a HOR hull is going to be better than a no brand ebay one.

I'll stick with the HOR hull then.

Hi Andrew [sm=thumbs_up.gif] ,

Don't get me wrong , for the price that they are being sold at they are worth percevering with especially if there paint work is going to fit in with what colour & scheme your considering as i know they are being produced in different finishes . Just a matter if you are prefering the hull in question , buy it & work on it - such as strengthen the hull with Fibreglass where it requires it etc. , i know the next scale ( 36" ) up from that supplier has a following . The hobby also involves perfecting our boats & considering what will get them there .... . If you can visit a club meeting in the U.K & just talk & walk around pits you will visually learn a lot ....

I'm happy with my Apparition , they are a good boat to get involved with hobby with - not a pic of my boat ......

All the best mate ,
Brad

Thanks again Brad. My opinion keeps flipping between them - I'm now back to the ebay hull!

I enjoy making and working on my boats most, and I'm more than happy to reinforce or add more fibreglass. In fact, thinking about it, I prefer fibreglassing to painting (I'm much better at it) - so I'd be better off with a coloured hull that needs reinforcing than a strong white hull that needs painting.

That would make the ebay boat a much more attractive option, as I'm not particually looking forward to having to paint the entire outside.

So, in summary, I'm now decided on all the HOR hardware, and that ebay hull. If no-one can see any obvious problems with that, I'll go for it!

Wow - get that boat directly from R2hobbies, and it's £5 cheaper than ebay. Register on their site, and they take another 10% off.

That leaves that hull at $65 - amazing!

I've now placed my order with them for the hull - thanks to everyone who helped me decide what to get.

I'll place my order with HOR for the hardware in a moment.

For anyone looking at this thread for reference, [link=http://www.r2hobbies.com/eng/proddetail.php?prod=rcbt0452001_code]this is the boat I have ordered[/link].

Right - that's everything ordered:

Turnigy/Seaking 180A ESC
Leopard 2000kv 4074 motor
32" fibreglass cat hull (yellow and black gelcoat)
Two 2s lipos (4000mah, 40C)
All the hardware from HOR
A cooling jacket for the motor
A 3/16" sleeve for the prop


I'm really looking forward to this project - hopefully it should keep me busy building for a few months!

Just from what I've seen and heard about that hull, I would stop payment and get something else
it may not handle the power your going to throw at it because of the quality of the hull [:-]

I think it'll be OK.

I'm planning to add a couple of layers of carbon fibre around the points where the motor is attached, the shaft leave the hull, and where the rudder/strut attaches to the transom. If it's not rigid enough, I'm also considering glassing in some 6x6mm beech stringers along the length of the hull.

As I said in post 18, that's the sort of project / modification I enjoy doing - I usually end up only using the boats a couple of times once I have finished building them - then I want a new project !

Are there any other sorts of quality issue I need to watch out for apart from rigidity and flexing?

I've read up a lot on it on various forums.

It seems that when it was initially released (June 2010), the gelcoat was a little rough in places - all the reviews and comments from 2011 boats say that the gelcoat is excellent quality and very flat.

As for the hull being poorly made - it is a $65 hull - I'm not expecting it to be perfect straight away. In addition, I'm not trying to break any speed records.

I owned the 32" single drive hull and the finish was perfect with very sharp sponsons.

Sold that as it was too small for a twin then they released the 36" twin hull. I bought one of those and I'm VERY happy with the quality of hull, finish and very sharp sponson edges.

A steal at the price they are asking and I always add Carbon/Kevlar matt to my hull anyway.

Also bought an Arowana. Excellent hull & finish, needs extra CF/Kevlar matt but again, very inexpensive and a nice deep Vee. The one thing I do not like on the Arowanna is the transom is angled oddly and I may need weges to have the hardware mount the way I want. Other than that, nice boat.

You have to take in the fact that Hydro & Marine sells hulls of similar quality, not too thick of glass layups and the prices are triple! You also get more colour choice from R2 hobbies.

Yes, you could buy these chinese cats at R2Hobbies .com slightly less than ebay after you register.
