Available through Icare-rc. In Canada that is!

Where can one find this ESC? Do you have a link?

Got it, thanks.

Pete,
I have heard this story a few times and not just on CC controlers....., this must be a serious manufacturing problem I'm sure????
Is it the caps, FETs or something else going bang?????
I work in engineering and find it hard to believe that in this day and age they can't make a relatively simple device work 100% reliably???? IMO.....

I guess my biggest fear is I have no clue as to how high the amps will fly when I grab the trigger... and from reading in the forums nobody can hit a twin setup dead on. So I feel it is better to be safe than sorry.
And where do you find the AS 150's?

This is a bit late. You can figure your amp draw if you have the proper info. It is soley your responsibility to educate yourself on your setup, asking other folks is fine, as long as you realize its just that, other folks setups, not yours, not your experience and not your conditions or equipment.

The motor manufacturer will have ALL the info you need to figure your motors max capability, if they do not have this info, find another manufacturer. This info coupled with your esc (same thing here, if the esc manufacturer cannot provide white papers on the esc find another manufacturer) info and the type of info you have researched on your prop choice you can easily figure your amp draw, again education in your hobby saves your wallet.

No one can tell you what you will experience with your setup without standing beside you assisting, there are so many factors involved, the biggest being your knowledge of your equipment.

Here is a simple question. Do you know what can happen to an esc when the batteries are disconnected and the esc is not discharged? If you cannot answer this then educate yourself a bit further instead of building that big rig and "wondering" what it will do, or why it burned up.

graill, I have educated myself on what the system will do and why but the problem is that most of the knowledge on the motors, cell count, esc's and hull size is mainly based on single motor setups. My problem is not what I can get away with in my setup but how much and little can I get away with.
Fisrt is my speed goal 100 + mph
Second is that I do not want more than 6s per side.
These are things that havent been done together that I have seen. I want to run 1527's but on 6s will it give me enough rpm's to meet my goal? Now knowing that the 1521's will give me the rpms but will they handle the load and and to go futher with that they are only rated for 21 volts. I do now understand that buy there being two motors instead of one the amp load will decrease, but by how much? These are basicaly the things I was asking. I thought the purpose of the forums was to share ideas and pass knowledge from one to another.

And yes I do know the answer to your simple question :
Anything electric has the abillity to shore energy and eventhough stored for a short time it still has the abillity to discharge that stored energy, sometimes in more violent ways than others. So by all means you can short out a esc after it has been disconnected from the cells used to power it.


Please don't take my answer and replys as smart azz......
but I'm trying to build a nice boat and not trying to do it by making a exact copy of the next guys boat.
Case and point: http://hpr06.speedtoy.com/setup.htm
scroll down to Flo...... 161 kph thats a 100 mph setup!

[vvviivvv]

You should copy his new set up... 208km/h

so say the neu 1521 1y on 6s it's max watts is 3500 Does this mean the amps should be around 150 max??? And I'm clueless about figuring out what amps a certian prop will take

Dont worry about it, forums are vanilla. Tracking folks new builds are always exciting, post pics and results.

208kmh???? Wow!!! What's the setup on that? Who's is it????
Back on the question of ESC', Has anyone used Suppo gear? I have 2 70A units in my HOR and I am yet to get it in the water but they also do others upto 200A from 2-15s LiPo's (3 models)....

Florian sho... cant spell it known as 'flo' was
2x LMT 2250/7 HiAmp LK/WK
2x Schulze 40.160 WK
2x 8S HackerTop Fuel 5000mAh 30C
2x PropShop 4518/3

[KillerDave]

Is there a link to his build? Not that I wanna copy but it might be good to see.....

[vvviivvv]

The boat wasn't built with them motors I don't think... I'll try find the build later

[Gerwin Brommer]

Flo ? 208 with an hpr115 ??
Or Achim Kurreck with his hpr135 on Neu's ??
