Ok guys I have a spare 15t motor laying around still new in its package and I wonder is it possible to run this with the stock esc? What is the esc turn limit?:confused2:

I highly suggest new esc, stock is garbage. I burned 2 of them up. To answer your question it is listed at 27t.

I think the weak link on this boat is the esc..

Yea UPDATE I ran this new boat today at the local lake and about halfway through my 4000mah 2s 25C lipo the esc gave out. So when I got home I realized wait a minute I have all the electronics out of my Apache 24 which is under construction right now so I did some soldering and moving of things and came up with this.......

It should do for now in a few weeks I am going to get a VXL3S system from my friend. And i will run that with a better cooling jacket on the motor with a 3s and see where it goes from there!

I think that may be to much kv for a apache. VXL motor is 3500kv correct? Anything above 30mh on a apache I read the hull cant handle. Good luck though, I would love to see if you can get it working right :rockon2:

Cool, glad it is working well for you. After I blew my second one I bought a waterproofed xl-5. A little more $$$ for a brushed esc but sometimes I don't mind paying for peace of mind.

Diesel here is one on a 3600kv motor and 3s everything else besides the esc of course is stock and it seems to be fine to me. Now keep in mind i understand it will need to slow down some before turning sharply but it seems to handle ok here......

You sure that's a 3600kv motor on 3s and a 42mm prop?
it is faster than stock but not 40k rpm. :confused1:

What motor are you running with the Traxxas esc?

that video does not look like a VXL powered Rio ep on 3s.. :confused2:

it isnt but if the kv is the same than whats the difference?

What motor are you running with the Traxxas esc?

I was running a Titan 12t on a 7cell nimh. Hit 19mph with stock prop. I put the stock 550 back in though because I converted it to a rescue boat and needed lower rpm higher torque the stock motor had for pushing a stalled/flipped boat.

You said it was a VXL motor, now its not.. :confused2:
a VXL motor on 3s is a monster!
almost 40,000rpm and on the stock 42mm prop tha Rio ep would fly! :rockon2:

No i did not say the guy in the video was using a vxl system i said i am using the vxl system in mine and i was showing the video becuase it had a brushless system in it that had basicly the same kv rating and cell count

read post #13 and on..
I don't think the video you posted has a 3600kv motor on 3s, that would be right at 40k rpm and on the stock 42mm prop it would move out real fast
he is posibly using a 2s pack :thumbup1:

im not saying that you said you were confused i was just clarifying for you 55. I dunno either that or its like a 15-20c 3s just a guess on my part. anyways ill be ordering 2s and 3s so i can try both.

Clarifying, I'm not sure what that means?
I was asking about the video not your setup, because the video looks slow for a 3600kv motor on 3s with a 42mm prop.
the video you posted that I was talking about looks more like he may have used a 2s pack or even a 6cell nimh pack with that motor and prop :thumbup1:

hmmm interesting i will have to try the 2s first then and if im feeliing lucky and heat is low then ill try the 3s

Well I ran it with the current setup with the apache esc and the apache motor and the motor died within two runs on the 2s lipo. So then I swapped in a venom 15t motor I had laying around that was used once before for a run to test in the apache and within one run the apache esc died. Thats just my luck:doh:

the venom 15t sucks some amps, and they don't put down much power..
go brushless bro!

I am now considering I used all my leftover electronics up in this boat:olleyes:

Just have to wait for more money now :thumbup1:

My buddy blew his apache motor after only about 5 runs... SUX!!!
