All you FE experts have any thoughts on leopard 4074 2000kv on 6s?

[jimbo--jones]

Picked up two 2000kv leopard 4074s for a bargain.

I got two turnigy long 6 cell 5000mah 25 to 35c batteries. These are 2.5cm high by about 30cm long, and they fit in nicely side by side in my apparition hull, allowing easy COG adjustment.

I know 6s on 2000kv is too much rpm, but these are the batteries that I'm gonna put in.

I'm using 2 Turnigy 180 marine escs and octura x442 and x442r

MY QUESTIONS IF YOUS WITH EXPERIENCE CAN PLEASE HELP ME OUT:

What will go wrong?
Will there be too much heat?
Can I just not give the system full throttle to keep the rpm down? ( I know the escs dont like running at half


Im thinking if heat is going to be the only issue I'll have that covered.
Installed 2 dual flush mount water inlets (4 intakes and 4 outlets)
If thats not enough I have a self syphoning fuel pump thats going in to keep cooling when boat is stationary.

I have lost a feigao 10xl and T180 on 6s before because of heat, so im making sure I dont lose another set up.

Any feedback appreciated, Thanks for your time

The pumps will not help your speed controller from blowing up...you already know whats going to happen so why do it? Its going to be insanely fast but its going to smell after too

i run a t180 and a cc1515 2200kv, i have maybe 10 runs and no problems yet

Whats the reason for the esc blowing other than over heating/ driving into a short from motor windings melting? Both escs will also be getting cap banks infront of them.

if this boat is going to be used for one pass up and back then it may hold up..but for any sort of length of time running the esc's will more then likely blow from too many amps/heat buildup..i do not believe you will be able to keep them cool and your amp draw is going to be over the esc's limit...its sounds like a fun expiriment though

i am by no means an expert but even with these motors on 4s lipo the boat would be a rocket and much much safer on your electronics..and you could actually run it until the lvc kicks in too which is better than the popping sound and then magic smoke lol

My buddy runs a Leopard 2350kv,swordfish 240 hv on 5s2p and it comes in cool.
I dont understand why because it gets thrashed for 3 mins and hit 69.3mph on the gps.

cc 1515 on 6s

240hv would be part of the difference and prop choice is key too

[britscoot]

m455 was the prop.
It is freaky when this thing comes in cool.
Its a 32" cat and nothing special.
did i mention it comes in very cool....lol

I say a cc1515 1y on 6s is too much RPM and your leopard on 6s are going to be way to much also. I woulnd't run either setup, possibly blowing a setup chasing speed isn't worth the $$$ to me. If your wrong your gonna blow a possible 2 motors and 2 esc's. Could be a $400+ learing experience, or you could get spend under $100 and get a new batteries. JMHO

Sounds like an expensive disaster waiting to happen...........

Cap banks won't help if the motor is being pushed to hard. I have smoked ESC's and the cap bank was just fine.

[jimbo--jones]

I know 4/5 cell would be the safer option.

I only wanted 2 batteries though, and not 4 batteries to get the capacity and to get them to fit in.

I got the 6 cells because their capacity is ok, its a single battery, and they are low profile.
