big kitty - Cyclone 45 build

[Jesse J]

I will have to measure, but for now I am guessing not more than 2.5" maybe closer to 2"

[Jesse J]

Yep my memory was right - 2.3 " below sponson.

Well Jeff, that cable is nothing short of AWESOME!! I got her in and my stuffing tube was in just the right place (I actually installed it before the cable got here - I know tisk tisk). Now all I gots to do is mount the GIANT esc to some brackets and make some battery shelves. I was thinking in the sponsons I could throw down some ply shelves that would elevate the batteries 1/2" or so incase of any water infiltration.

Question: what is lower end rpms one should run a motor? I have a pair of 5S 6600mah packs I was wanting to try for the maiden voyage, but that would be turning the motor at not even 20K.... is that too low?

Glad you got it. I did somthing different on the coupler for you with 6 set screws. Do solder the end of the cable before you set the screws to it.

Pretty low rpm but depends on the prop you are spinning. I would rather see it around 25-27,000. If you have the torque then a big bad prop can push it decently.

Ya, you always set me up with gorgeous couplers - a man who takes pride in the details! Will do on the soldering - wudnta if you hadn't said so.

Kinda what I was thinking...

Question: have people been seeing the Monster 2000 heating up? I have thrown a couple water lines along the outer edges, but was wondering if I should do more water cooling and/or hook up a CPU fan as well?

Jesse not enought people have run the monster to get enough feedback... I've had a few of them... I ran one with no cooling at all with a scorpion 4035/800 on 10s for 3 minutes...and she ran kinda hot... 150 degrees..... I would recommend cooling lines and a cpu fan just to be safe til you get a baseline, like I say because no one has enough experience on here with them to say so.... let me know when you get your "loaner" program card

[Jesse J]

Copy that, will do - I have a huge CPU fan just sitting here. So you got your DF?

Today!!! missed it yesterday...home is a long way from work and they needed a signature... the post office lady knows me to well though... she called me this morning and told me she had my package... LOL...

[Jesse J]

she called me this morning and told me she had my package... LOL...

Hope your wife don't find out

took out the little kitty and got her wet. Kinda wondering if this motor is gonna get me up to 60 without burning out first.

Here is video, its a quickie with no effects... just a documentation clip.

I ran her on 6S2P (7200mah total) and a X460 prop and after a minute or so brought her back in and the motor was probably 160-180... I have a water cooled mount, but it doesn't seem to keep my temps down. The Monster was warm, maybe 120 or so with two cooling lines along the outside fins. I am thinking of making a big water box to set it on where the whole base is cooled, ahhhh.

Does this prop sound too big? or the motor just too wimpy?

Also, please comment on ride attitude.

well i run the t600 1400kv on 6s and it stays around 130-140 after 2 minutes. i think you have 2 problems going on here.
1) i run it in a much smaller, lighter 32" cat
2) i use a m445-447 prop

i think a 60mm prop is going to require alot more motor. those are torque monsters but a 60mm prop on a $29 motor? that probablly aint gona happen. from what i have seen $450 neu 2215's are turning 455-457 in 43" cats. that is alot more motor, a little less prop and just a little more hull..

Jesse, see here my Monster ESC:

I added watercooling to the top only for now, but the 4074 on 4s is a very cool (literally) combination. A good 4 minutes of wot running and everything was nice and cold. For watercooling the Monster, see here:

Very easy to do, very effective.

I run the 1400 on 5S2P and a x450 D/T & thinned in a 29" Phantom cat. It does a decent 50+ mph, possibly close to 60, I have to GPS it.

I first tried 6S1P but, felt it was excessive rpm with a 45mm prop.

The temps & amp draw for 50Mph are very nice & low. I want to try some other props before the water goes hard here.

Using turnigy 180 esc @ 15D timing, plug & play basically.

here you can see real numbers from eagle tree with a m445 on 6s... it is allready pulling 163amps

[ray schrauwen]

Thats why I say 6S is too much, too many amps. That is why I went to 5S. Turns a bigger prop.

My buddy runs one on 6S in a PT sport 40 and it does a good 60mph.

For $30, what else could you want?

Try a Leopard 1090kv 5692 on 7S, I am...

Think outside 2S, 4S, 6S, Etc...

[Chuck E Cheese]

why is 163 too many amps???? keep in mind that by turning a bigger prop the amperage is going up even though voltage is going down...

remember that when the end result RPM is the same a 6s system will draw less amperage than a 4s system. given that the kv isnt changing i am sure your lower voltage/big prop is drawing less amperage but i am curious by how much. i feel that 160 amps isnt out of line and perfer the way the hull handles on smaller props at higher rpm... this also is peak amps, not average..
