Nice boat but dont deal with mhz usa they arent reliable,if you want mhz products go direct to Germany theyre much more reliable.Have read some real bad things about mhzusa so beware.Have a look on RCuniverse and see for yourself theres plenty of threads on them.

i saw them on youtube tonight 144 km/h  :-))

mind you, the RC top fuel  Drag racing boat looked fast too, the full size versions in America do 250mph in the 1/4, but look extremely dangerous  %%

the engines for this cat will cost a fortune  >:-o it's either NEU or PLETTENBERG, or similar high performance engines and they all cost roughly the same, over 200 quid each, the large Cat on the NEU website has done 126 mph.

These watercooled engines are a fortune compared to their aircraft counterparts, i had no idea there was such a huge difference in price  :o

well, maybe i could use the aircraft engines then, just dont tell them; or they'll nag me/warn me to buy the more expensive marine versions, but i need to check out carefully the aircraft engine's specs.

the only main difference that i can think off will be the lack of cooling, but there might be something else too, but you can make your own watercooling easily anyway, just bend a thin tube around the case 6 times, like the Graupner version.

i'll investigate these aircraft engines this weekend and if they're ok, i'll buy them on the quiet!

to be honest, i'm reading a lot of BULL*** with regards to these hi- po marine engines on other forums, it's all about buying ``bling``and this ``bling`` costs a fortune, because i'm sure that you can also use large scale ``Buggy or Helicopter`` engines as well, but you need a decent shaft diameter, between 5 and 8mm.

i bet all these monster engines are the same, just dressed differently.

but i cant afford the expense, maybe it would be cheaper to get a smaller cat, with a single Plettenberg; or two of those Chinese cheap purple motors.

after all, it's doubling up on everything that costs so much with these twin motored cats, spending that much money is crazy.

Why not go with a petrol powered cat you will be able to see 60 -70 mph and cheaper by far than leccy.

Hi Mal X,

Unless you've got the budget, equivalent to the price of a small car, I'd suggest you do as I do and only watch these video's on youtube...

If you're willing to go not quite as fast, with a smaller cat and Chinese motors, you can get very respectable speeds at a fraction of the cost.
But; if you don't have the skill and experience to build and set-up a fast cat, never mind; it's going to be a bottomless pit where you'll be throwing in cash indefinitely...

Keep in mind that the high speed crashes can be very costly, no matter what motors or ESC's you're using.

Regards, Jan.

No need for 4 or in that case even two,one fully modded zen will push a good sized cat to 50 mph,smaller cat at 40"-45" will do 60 easy.If you want a bit more twins or one inline setup will get you 60 mph.Heres a vid of my mates cto3 with twins she hits 60 mph no problem shes 67" long.The green hull in the pics is another friends and has two inline twins he has her for sale now in fact it might be sold now hes in the states though,she was built by comision by the builders of the real one and cost arround $15,000 or more at the time maybe much more i cant remember exactly.

Hi John J,

The motors I was referring to come from Hobbycity, I'm using the Ø36 mm motors in my monohulls.
If you need more power, the KB45 series is cheap.
Keep in mind they need very(!) good watercooling and running a lot of partial throttle isn't advisable, you get what you pay for...

So far, these motors have worked for me, only a single failure in eight motors and that was my own doing.

Regards, Jan.

these petrol engined cats aren't that fast :-

http://www.offshoreelectrics.com/proddetail.php?prod=neu-2215&cat=117

this Neu 2215/1Y 30 Cell electric engine will give a 53'' cat a top speed of 126 mph, as will the Plettenberg etc, the petrol engine cats just look like bling that's all, yes; all of these top electric engines are seriously powerful and expensive, but if you want speed then you need to go electric.

http://www.neumotors.com/Site/Boat_motors.html

but you can probably get the same speed with only one of these Neu motors, in a smaller 44'' hull ( a HPR 006 hull or a Mystic)  this will half the cost, you dont really need twin drive, some Germans only use single drive and they get up to 150km/h and that's with a less powerful motor!

all of what i'm talking about here is for a future boat, right now i have to think what to do about Magin 1

Thing is theres not many cats will actually go over 100 mph and stay on the water {-),even if you can get one to go that fast it will not be running round buoys it will be running straightline courses.If you think a 60 mph boat is slow come back and tell me that when you have actually driven one  %).You sound like your an expert allready yet you havent even got a fast electric never mind anything else.I wont waste my time anymore,carry on  {-).

sorry, i did mean to get all mouthy, i'm just very fed up with Magin 1 that's all, plus i've been working nights.

yes i notice that these really fast electric cats are used mainly for speed trials only and when they turn or go round buoys they slow right down, maybe because of the fear of capsizing them

hi  :-)), yea' thanks, but still watch what i post in please, because i still need advice, i think i'll keep Magin 1 for a rainy day and finish her off when i'm more experienced with fast electrics, she looks good and i'm sure she'll be fine, but maybe only fit for the current Graupner engine that i already have.

spending loadsa dosh, is only really viable on a far stronger/ faster hull form, that already has powerful engines and this is definitely the HOR 32'' Astec cat :-)

speaking of which, i sent him an email tonight, but he hasn't got back to me so i'll ring him tomorrow, they all race what i'm after too; so she'll be ok.

i dont want to spend too much on my 1st Cat, i'll only go crazy on my 2nd...

i now need to research a colour scheme for her and re-do my decals  %%

http://www.astecmodels.co.uk/catalog/product_info.php?cPath=2_86&products_id=789

this is the one i'm after, i've spoken to him quite a lot recently, it is not the standard engine from China, he's fitted an even more powerful version, he's also got a twin motored version too, this Cat is 4'' longer than MAGIN 1 and an 1'' wider.

i'll get her in JANUARY  :-))

i've got a custom paint job for her plus the decals

http://entertainment.webshots.com/photo/2317566400105369285MQWOwZ

i'm not sure which metallic paint job i prefer, i think the purple/ pinkish looks maybe best, but i've loads of racing decals etc... i have a large spray compressor, all i need is another airbrush
