Mystic C5000 (44.8 inch) Twin setup suggestions

[xkos]

Hi,
in a few days my new hull (MHZ Mystic C5000 44.8'') is coming and i need your help in order to make it run with speed 60-65mph. So i need two motors without spending a lot of money...

Setup #1:
6s lipos 5000 30c
2x Feigao 580L 7L motors
2x Etti 150 opto
octura x442r/l

Setup #2:
5s lipos 5000 30c
2x Feigao 540XL 8XL motors
2x Hydra 120
octura x442r/l

Which one will make the little mystic run closer to 60-65mph?
Any other setup suggestions?

The setup#2 is also used in the HPR06 (about same length as yours) here

http://hpr06.speedtoy.com/setup.htm

but you probably know that, however it looks that setup#1 will be faster.

I have a slight different opinion... with all due respect, you get one of the nicest Cat hulls out there
and you are going to use "B" quality motors in her?
I'd wait another month, save some money and get a pair of good motors to go along with this nice hull.
Go with setup #1 but with a "A" quality motors... there is plenty to do before you get to the motor install/placement, that'll give you time to save some $$$
Sorry if it sounds rude, it is not my intention, I just think that a good motor should go in there.

agrees with hauled .. .

Don't go dual drive. It's a pain to build and to maintain. Get one big motor and one big controller.

you beat me to it that boat deserves A class motors for sure
in saying that i own two MHZ hulls my Lizard does run a B class motor but in the Chaparral i have gone A class all the way

Xkos, you lucky man! That is a sweeeet hull man and it deserve some decent Neu's... Post some pics or a build thread when it arrives.

I'll throw in my 2 cents worth. I have researched, asked and read up and down 3 very good forums ( here, rrr, and xtreme )
I can tell you a few things.
A 45"cat needs a lot of power to go 60+ mp/h
Power is not cheap
Twins sound beautiful. I have not done one.....yet !!

The general consensus here is do it once and do it well. This will mean good packs and good motors feed with good escs.
I have a few smelly hulls and know what low-cost escs or motors do.

Up to 30" you can go low cost and fast, beyond that length you are looking at big coins. Beyond 40" ( my biggest rigger is not even 40" ) and the coins go up at an alarming rate if you want 60 mph.

I have read here "cheap, fast, reliable...choose any two"

I have a lot of written stuff for twin-drive cats and will help where I can.
Jay Turner is a good Cat man as with Jesse J and Gerwin Broomer knows his stuff too. There is a LOT of knowledge here.

Just ask and I may be able to help.

[Jesse J]

Careful Simon, don't give me too much credit. I just try not to repeat mistakes too many times and share when I learn something.

Cheers, mate.

[Gerwin Brommer]

Same story for me.
I'm not an experienced racer.
I find it hard to chose a setup for a boat.
I only know a few things about how to build a boat the right way.
All i know is not by doing it, but by reading about it.

Thanks for your help.
I need to learn some things about new 36mm v2 medusa motors
Has anyone tried them in twin setup?
I think that a pear of 3670 or 3680 2000kv will be better choice than feigao running on 6s.
What do you think guys?

I think the kv on those motors are way too high, 36 mm motors are babys if you not going to run Plettenberg,Neu or Lehner the minimum i would run are Feigao 580L or KB45 it looks to me that you are trying to do this the cheap way and in the long run it will only cost you more money,do it right first time it might take you longer but you will save yourself some money in the long run
My Next project will be a cat around the same size i will run single motor i will use the Motor/Esc/batt out of my current boat
Plettenberg HP/370BM/50/A1 S - Schulze- Fut-40.160 WK -12S - 2X Hyperion VXG3/6S/35C/5500mAh
Bite the bullet mate do it right

I run a Toysport Twin Jolly w/ 2 Feigao 8 XL's, CC240's & 4s Lipo's. I got it with the drives installed from Mr Toth ... for me I don't know much either but I'm learning with everyones help here and on RRR!

Just got a Geko GPS so I'll get a speed on it soon! I'm guessing its in the high forties but am still dialing it in.

Not this weekend though have a wedding to attend out of town without the kids so no boat running for me(although my motor will be running)!

My intentions are to upgrade to Neu's in the near future ... and hopefully to 6S we'll see!

How big is The Toysport jolly

I did a lot of research on twin powered cats as I was looking at doing one at 36"
This is an unusual length as twin L's were maxed out and twin XL's were too much.
I read a lot on quite a few forums including non English speaking ones, the bonus is that numbers are numbers and data can be gathered from foreign languages if you know what to look for.

This hull that you have is comparable to the HPR 115 that has a huge following and some very serious speeds have been set with twins.
Some of these have used the Feigao XL motors. Despite the fact the Plett, Neu and Hacker are very good motors the Feigao is still a good motor. It is often bagged as cheap and looked down on by some.

Bottom line is a pair of 8XL's on 4S will fire a HPR 115 over 60 mph.
This I have from a reliable source. I'll not name him unless he wants me to. A few PM's will be needed to do this.

Your boat, your money and your call.

I will help where I can.

For interest. The research that I did into twin cats is about 30 pages thick in one of my info folders. Yes I am old fashioned and print stuff, that way I can read it anywhere-anytime.
