Blackjack 2300kv motor upgrade ?

[Pete32200]

is it possible to run a proboat or turnigy 2300kv on 4s with the stock esc? I already have a pair of decent 2 cell lipos and figured it would be more cost effective to upgrade the motor instead of getting a new ESC and a Pair of 3s lipos.

I have heard of guys using the Blackjack ESC as an upgrade to run 4s on the shockwave that has the 2300kv motor and was thinking that it would pretty much be the same thing.

Should be faster on top end mph but may lose a little acceleration getting there. All depends on what you want.

Ever thought of buying two 3s batteries to match your 2s? You could then run 5s, and either have an extra set or run 5s2p. I personally run a lot of battery combos like that (in my big boat I run six 3s batts for 9s2p, or four 3s and two 2s for 8s2p, ect...). You could then run 4s for "sport boating" and 5s when you want a little extra speed, and 6s when you wanna go fast and buy new parts

BINGO, 5s on the stock motor/esc = , without a doubt would perform better that the turnigy 2300 on 4s. Spend the money on the other matched batts. Set the motor timing to high run 5s witha x642 and that thing will rock. JMO

Is that why it seems like im burning up esc's on 5s im not running everything on high settings? the cutoff voltage is the only thing set to high. Do i need to set timing and throttle curve to high too?

How many esc's have you burned?
Switch motor timing to high, disconnect the esc's internal bec (with a small flat head lift the locking tap on the esc connection that plugs into the in rx and pull out the red wire) after that run a seperate rx pack, that will help with heat on the esc. What size prop are you using?

This is the second or third. One went on 4s it was an older 45amp stock esc and two went on 5s only 1 caught fire tho. running stock composite prop 1.6x2.5 with ss hardware and turn fin. dual water cooling. Had one heat issue on a motor added more cooling fixed that issue. then today puff the esc. Does it help to know that its unsoldering the blue wire bullet connector? Happened on both 5s. Also stock bj motor everythings stock but 5s and running hardware.

At this point I would replace the motor. Your stock prop shouldnt be drawing that much current (unsoldering wires and killing esc's) unless there is another problem. Make sure there is nothing binding in your driveline. If not, I would replace the motor. Ive had a couple Feigao's that would kill esc's at the drop of a hat but you couldnt tell by looking at the motor.

I agree with the above. Something is def wrong with your setup especially if the stock prop is killing them. I would return that motor and change over the conectors to 5.5 on all ends, batt/esc/motor. I love those 5.5 on everything. Something besides the esc is the issue.

I didnt mean to steal the other dudes post! is the 2300 better then the stock B J motor? lol just to keep topic. First run with new hardware it ran about 180 degrees added more water cooling dropped to about 110 (normal i think on 4s atleast thats what ive gotten) so didnt think much about it. Ran today same effects right before it shut off and burned. running cool batts were not heating up esc was not hot nothing. checked the water pickups everything was clear let it cool put the hatch back on didnt tape it up turned it on it went through its 5 beeps and i hit the gas to do a prop direction check (quick blip nothing harsh) and boom fire works got my batts unhooked and let the boat finish its cheech n chong session. now here i am yay!

got a quick question about running 5s are u running 1 2s pack into one connector and a 3s pack on the other to get the voltage ??

Yes that is correct. The packs have to be same discharge rate "C" and same capacity "mah" I also use packs of the same brand. The stock esc is wired for series with the jumper between both connectors meaning voltage is added, mah stays the same.

So a 2s 5000mah 40c lipo + a 3s 5000mah 40c lipo will = 5s(18.5v) 5000mah 40c

The BJ motor is without a doubt a much better motor hands down.

At 180 the motor possible de-magged or did some serious damage. I would believe your motor is the problem on why you are burning through esc's please send for warrenty or change asap before sticking another esc in that boat.

Thanks for the heads up i was damn sure about to do it too. Okay i know im beating a dead horse but if you take the total voltage of a full charged 5s combo by 2s+3s is 21volts total on the head correct? being 8.4v and 12.6v right? or it dont work like that? Is that to much to be right at the limit for the 45amp esc do i NEED to d/c the bec. also people talk about 6s on the stock esc thats 25.2v BAD BAD BAD?

[boogeyman]

thanks deisel that clears things up for me
