Blackjack v3 runs to hot on 6s

[waterproof]

In the op's defense, it's stated that this setup is ok on 6s. It was tested extensively by proboat to put that on it. Now take into consideration that out the box before he started jacking with it, he said it ran just fine. In my mind, the problem is not the boat, it's the user. He did something to cause this. Plain and simple. This boat runs just fine on 6s if you don't go messing with it. Now he's got to put it back the way it was stock and it will be fine. It also says you need 50c or higher batteries.

Waterproof.....if this was my boat this is what I'd do:

Put castle 6.5mm green connectors on it
Shorten all the wires as much as I can
Put 6.5mm castle bullets on the motor
Put the strut back where it was stock.

I know you say it should be good to go out the box....it was until you tampered with it. If you would have left it like it was, it would do as it was designed. I'm not sure your reasoning for moving the strut (go faster maybe) but there will usually be a trade off when you go messing with things. If you put it back to stock settings, make sure it's greased, make sure your using the recommended batteries and stock prop...it will be fine. If you want more speed, your gonna have to do some upgrades....starting with the connectors....it's that simple.

I have not messing with anything, raise the strut 2 mm from stock so the sponsons hit the table and the boat rest on the strut, the guys that run the proboats cats recommend this to get it stabile and run lighter.
Raise the prop should do so the boat run cooler because it runs lighter. Out of the box the strut is little to low so the boat runs little to wet.
I did it because i want cooler temperatures and it not reach 45mph like the strut was.

Like you said it works fine the first run, its maby because i was easy on the trottle, after i get tip about to run more with full trottle i tryed to run with more trottle and then everything was hot.
Timing was stock on 15, and now it is 7,5 and it help but not on the connectors.
I always regrease for every run.

Thank you for the advice, the wires from esc to motor is long and zipntied under the front of the hull.
It got 5,5 motor connectors from stock but its a good idea to shorten them and try 6.5mm.

6s to do 45? Should be easy as pie. A lot of us get to the 45 mph mark on 4s. you may just need to limit run time

I'm in the 50-51mph range with my Lucas Oil on 4s

but his one sounds like its running wet
possibly the batteries are a little to far forward ???

I'm not at all impressed with the V3. I sent my V1 back due to the hull splitting apart between the forks at the seam. Proboat sent me a V3 to replace. The V1 was my first boat but I had it running 55+ on 6s turning an Octura x440 while being nice and stable. I tried tuning the V3 the same exact way and i have one heck of a time making 45 on 6s

Here is a update.
Motor wires will be hot on 6s. It is not an issue since it works. I also lower the strut almost back in stock posission and it help a bit on the connectors. Now it is around 55-60c and it could also show higher temps up to 80 but most of the time they are 55-60c.

Now i have run it on 6s around 17 times and its work very good all the time.
Esc are around 45-50c and same with the motor. So the bj v3 is 6s ready :-) motor wires is not a issue.
They will not melt even they reach 75-80c and i have not reed about someone that have burned the esc on this boat.

Crispyspa, i reach 50mph on a good day with my stock blackjack.
I dont know the v1 but v2 is mutch more poor, not so mutch fiberglass and it must be blueprinted to not blow over at full trottle on 6s.

The version 3 is a way different boat, it runs very stabile.
I think the boat run more wet since you dont get the same speed.
What is your setup?

Everything is stock, 2000kv motor and the 120 amp ESC. Timing I assume is/was at 15. 6 cell. Stock prop with the bottom of the strut about an 1/8 above the pad. I tried lowering it, but to no avail. The thing with the version 3 strut is that you cannot put any angle on the prop because the slot doesn't give enough room. I hogged out the slot to give more adjustment and I reprogrammed the ESC timing to 7.5 to try out an x440 prop.

By the way, a Turnigy program card works on the v3 120a ESC.
