Bare Genesis and Apparition Hulls

[FighterCat57]

I've read some crazy stuff on this site... but 21 pounds of batteries in a 36" cat NAAAAAAAAA
805g X 12 LOL

It's a torpedo!

That's my Genesis

OK, that explains it. =)

Nice boat Rumdog

A twin setup 2x4S, 2x5S or 2x6S but 9kW

FC have you run this motor; Turnigy 500 H3126 Brushless outrunner 1300KV ?
I saw the scorpion 3026 1400kv Mudl used was rated over 1600 watts. I read these Turnigy 500's are closer to 1500kv @ 1500 watts, and for $20 a peice... probably an affordable alternative ? It might not run 80 but it should be very fast on 6s.

Mudl' s Genesis is very fast, A high voltage setup is a good idea. You should try 8S for 2 combos with two 1200kV motors
Low current, less heat that's good. Two Turnigy Marine 80A-HV ESC aren't very expensive

Yes. I run them in Das Boot. They are excellent motors with a TON of torque! Pete Z has water cooled mounts for just that purpose. Also, TFL is designing the water cooled mounts for production within the month.

It will have 2 outrunners per side inline and 6s banks of 5ah 40c batts on each side. (two outdrives with one on each side like a normal twin) Each motor will be around 100amps so 4 x 100amps(or a little less) x 23volts = 9200w and run counter rotating x457s hopefully when all done and maybe cut them down depending on the motor. And i am thinking the T600 1400kv and just not run it to it's limits or the 1300kv or 1600kv Turnigy 500 H3126 and run 80amps per motor. I have seen plenty of these ran on 5s x 2 so it won't be that much heavier. 5.4ish pounds of motors and batts if i use the smaller motors.

I don't know why that would be so far fetched? I am just trying to do different things.

I got the 80 HV's... I just don't want to sack up and get the scorpion motors @ $160... but as always you get what you pay for.

That would be 12 6s packs.

[RCKong]

seriously dood, I have found there is a fine balance between boat size, its capacity, weight, and power. If one of these is more than the other it negatively effects the performance of the machine. Thats alot of lipos to have to get from the bottom of the lake.

[Jacked1]

I think there is a misunderstanding!
Bahahaha! I agree 12x6s packs is INSANE and would be very expensive after it sank the boat!!!
I am talking about 12 cells total so 2 6s packs.
so just 805g x 2.

And my setup prolly wouldn't be able to make it to 9kw but it would have the potential. Anyway i just think 4 motors would be freggin awesome!

[RCKong]

My bad...LOL

Do you have a genesis? Your plans may change once you have the hull in hand. I planned twin 1520's with 6s1p per side. To even fit 1 6s 5000 mah pack i the sponson, some trimming of the deck lip is needed. I opted for 9xl's and 5s1p per motor. Still a snug fit.

hmmmm.. i would prolly get the 4 x 3s packs so i dunno if i could put 2 in the middle and 2 in the sponsons and put the motors back as far as possible? but anyways if it all doesn't fit i will just move it to a bigger hull or run 4s and higher kv. Thanks for the info!!

And sorry FighterCat for junking up ur thread!

I've got a couple of 8XLs for mine, but after seeing the size of the hull (it actually looks small for its size, and its a lightweight) I,m thinking twin UL-1 systems on 4S each would be more than enough.
