H&M No Step 2 s 14

[wayn]

Hi everyone, I have ordered H&M No Step 2 s14 mono hull.
Dia 25-5" x 8-25", light weight fiberglass and gel coat Hull. I want to get ideas on setting it up for oval racing, but restricted to 7.4 v (,2s) lipo battery, I want input on motor size, hardware,etc. I have a ETTi marine water cooled 90amp esc, also a turnigy water cooled 120amp esc. I want to know wheather to use a strut or stinger? Also I need it to be fast.
So all you over sea's boaties I need you all to rack your brains , so I can give my Aussie mates a race and a half.
Cheers To All

Bump. Just bought one off of the Swap Shop. Looking for a good suggested motor for this boat running 4s. I have a 10xl that might work just for sport boat usage, but any input is welcomed on the motor...

[Rumdog]

SV, UL-1, or Proboat setups would be great.

Ammo 2300 as well.

Is there much difference between:
1. Feigao 540 10XL 1,734 RPM / Volt (0
2. AquaCraft Brushless B36 Motor 1800kv
The numbers say they are close, but is there some other factor that I am not aware of that makes one better than the other?

if you want to run 2S you will need a much higher KV motor, i.e a 2000KV motor is just good for 4S so a 1700KV motor will definitely not spin fast enough under 2S!!!
go for at least a 4000-5000KV motor, a 540 06L Feigao should do it
IMO the main concern is that to go fast you'll need a lot of amps, way abov what your ESC and the motor can handle!

[Rumdog]

electric has stated that he'll be running 4s.

[ED66677]

Electric yes but not Wayn!!!

Both ideas are welcome. I could just decide to run it 2s2p instead of 4s1p.

[ED66677]

Higher voltage is the way to go!!! at same power 4S means twice as less amp than under 2S... so smaller ESC, smaller batt...
a 1800KV motor won't be enough for a 25" hull, you will need at least a 2000-2200KV one, I have a 8XL on my 29" DF copy and spin a 42mm prop (43.5mm is the very max), if you go for a lower KV motor you will need a much bigger prop and even so it won't go fast, using a bigger prop will be a serious issue due to the prop torque, check this thread to find out what's best http://forums.offshoreelectrics.com/...ead.php?t=4159
and a XL type will be quite heavy but for sure will be a blast, this has been done by others! a L type would be reasonnably fast!

I'm building out a syncron hull right now which I think is pretty similar to your H&M No2. Steven also has (or had) a syncron and recommended for me a 540 8XL, and a 240amp ESC for 2S1P setup.

Chief, are you saying you're going to fit the 8XL in the Synchron and run it under 2S???
it won't go fast! never!

[electric]

I think Chief meant 4s. I am going to try it out this weeknd with a 10xl I have laying around for fun. I probably will see if I can trade the 10xl for a 9xl or 8xl in the swap shop.

Whoops, that was a typo! Should be 4S

Thanks for the catch,

[ED66677]

ok Chief much better then! BTW the Synchron is 28,5" long if I'm correct 8XL/4S is a perfect setup
Electric, if you can, go for the 8XL, IMO even the 9XL will require a too big of a prop for this size of hull because of its lower KV
