Twin 1717 Rio 51

[RIPFENCE]

Yeah thats what I was thinking. Would I get away with 200amp speedos as there half the price of the 240 ?

i would not recommend it with that big of a boat and how heavy its going to be..6s on these motors is the upper range especially with the bigger props needed to push that hull...in the end a 240 amp esc is the wise thing to do...no one ever said biulding and powering a big boat with twins is going to be cheap!!! do not cut the corners on the esc...just my opinion

Thanks !

I have seen a 50 inch cat build with the same motors running T180's so the 200 might work.

Thanks what about mounts these maybe ?? http://www.offshoreelectrics.com/pro...od=ose-drmount

I like the vac-u-pickle mounts. I use one in my skunkworks cat. Works awesome! http://www.vac-u-boat.com/BrushlessMotorMount.htm

Or http://www.offshoreelectrics.com/pro...prod=hug-b6666 and http://www.offshoreelectrics.com/pro...rod=hug-b6666r

The .187 3/16 cables would be a lot better then the .150 you listed before. I would use these, that motor is gonna put out some serious torque!

The 180 & 200 may work in the long run, I don't like pushing the esc's to their max voltage though. That's just me. I would use the 240HV's...

a vee hull draws more amps then a catamaran..just something to keep in mind

Thanks guys much appreciated. I just dont think I can afford the extra cash for the 240 amp esc's at the moment. Do I have to plug one motor in differently to the other to get it to spin the opposite way ?

Plug it up the same way, check the direction if it's not the direction you want switch around any 2 wire connections on the motor/esc.

I would run Seaking/Turnigy 180s with 1717's way before running the 1717's with the hifei 200.. the turnigy 180's have a burst rating of 360 amps whereas the swordfish 200's have only a 230 burst I believe.... I would run a 1717 with the t180 in a second... just me... especially in a twin motor application... less amp draw....

Thanks JMSCARD should I run an external B.E.C also ? Could I get away with using EC5 connectors on the battery side ?

YES definately run a external BEC or Rxr battery pack ..

also I myself would run bullet connectors.... 5.5mm or 6mm on batts, and 8mm on the motor side... this project should have them....

Thanks cant wait to start on this build ordering the motors over the next few days.

Looking forward to seeing a vid on this boat

One 1717 would push her 40mph.

Wow, I did not think one would push this big hull that fast, cuz that's faster than stock
I am using 2 of my 3 1717 motors for other builds, maybe 2 of my 1520s on 6s in my Rio 51z would be sweet

40mph might be a little embelished but would be real close...
