Proboat Blackjack 29" V3 - new hull, 2000kv motor, 120A ESC & EC5 plugs.

Thanks for the good review. One question. When you say your strut is level with the pads are you raising it up a little from where it normally sits when it comes out of the box? I've been trying to mess with different strut positions (only raising it) and not seeing much of a difference. Any feedback would be appreciated.

Hi luv2fly27,
Yes I am raising the strut. Adding no more than 1-2* of negative angle helps as well as this makes the boat ride flatter/wetter and is less prone to bouncing. This dos effect mph a little, but nothing major. It's either going to run somewhat smooth and lose a little mph or run dry with a bit more bounce.

As a person responsible for product development, I am sure Mr. Lopez ran the prop stock unbalanced for testing purposes. With all due respect, I would just like to remind you that for your maximum enjoyment, all metal props ( CNC props may be the exception here although I carefully thin their leading edges ) should be balanced, sharpened ( thinned) properly. The Proboat prop is heavy and some are more out of balanced than others in their "raw" form, and can cause excessive wear on the bushing of the strut.

That's correct, I run the prop unbalanced to see how long it will take to wear the strut bushings. Even after initial development, testing never really stops. The prop doesn't need much work to get it simply balanced, but as Darin will tell you, a worked prop will take many of hours. Usually, stainless props are closer to being balanced than brass props.

Hi,
If you are looking to blueprint the hull, reminder I have a video tutorial on that. This one is for the Blackjack/Geico V2 but the blueprinting will apply to any cat.

Just wondering about the offset rudder, was the mystic design, were it would sit flush on the back of the hull , not working ? . I have the kinteck kit on my Geico, and I find it 'dragging' in the water, seems from the video this hull has some of the same design on the rudder as the Kinteck .

Awesome videos on YouTube also, I never tire of watching them!

I got a question am ordering a prop I just don't know which one many say a x442 but I seen ppl put a x442 on a stock blackjack29 mines has a hobbywing 180a esc and a leopard 4074 2000kv which I've read it revs a higher rpm than the stock proboat set up I don't wanna order a x442 prop if it isn't going to do as well as a x445 prop I need help before I purchase this prop I know it has to be balanced and etc I just want to know which mm will be great for a top speed. Thanks

It is the same RPM on paper regardless whether it is your 4074 or the stock PB 2000kv motor running on the same cell count. Loaded RPM is another story.......Several of us said 42mm prop because you want to run 6s. On 4s, by all means the M445 would be my choice, in fact, it is my choice.
Spend some time looking at the props here at the OSE STORE, you will see a variety of props. Octura props need balancing and sharpening. The CNC props don't need balancing but still some careful thinning especially on the leading edge.
You also need to know the difference between x and m series prop. Too bad I dont have my desk top to help you, way on business and the tablet is so bad. But do a search, you need to know it to make a better choice.
If you are going to run 4s, then I would get the m445, x642 is also great. Note that in the x series, the 442 and 642 have the same dia. But the former has less pitch where as the 642 has more pitch. 4 ( pitch=1,4) 42( 42mm)...... 6( pitch=1.6) 42 (42mm)
That is how you read the props, so aside from the diameter, there is pitch to consider. The more pitch the more agressive and also the need to be cafeful with your temperature on tye ESC. Note this is just an extremely generalization, just want to give you a quick view, hopefully some other people with better knowledge will chime in to help you.

Homie u been a great help I appreciate u taking time off ur day to write that so others can learn I think umma start with a m642 I gps the boat today it ran a 52.1 with stock prop and adjusted strut I'll post a before and after video with the props again, thanks

I just got the BJ29V3..Great boat so far. Thank you for the info in the HW program card..works like a charm. With some minor motor angle adjustments, it runs much better than before...

Hi Guys,

Just joined the forum as I have recently got a new V3 Blackjack.

I have not had a quick boat for over 20 years, all my RC has been gas powered cars, and more recently I have been flying my DJI F550 Hexacopter.

Here's a few pics of new blackjack as it arrived.

Not had chance to get out on the water yet, as I need some new decent batteries, sadly my hardcsse 5000 4s are too big,,and probably to powerful too!

Thank you for the detailed picture of the inside of your v3 BJ29. Finally I can see the motor mount system and the nice beefy steering arm. Looks like they have done a nice job on this version. Your batteries should be as powerful as you can afford but, hard case lipos definitely won't fit as well as soft case lipos do.
There is no such thing as too powerful batteries for rc boats IMO.

[Nigelpugh7]

Thanks for the feedback on my post! Yes the hardware in the V3 BJ does all look like good stuff! If I am lucky today a set of batteries that I ordered might turn up and I can get out on my local lake whilst the sun is shining today. And as far as my big hardcase lipos, yes it's a shame they don't fit, as I am sure it will really haul with those fitted!

[helidan]

Hi mate!

So that's at least two Pistonheaders on here now!

These lipos might be worth a shot. http://www.hobbyking.co.uk/hobbyking...dProduct=31929

They're cheap as chips and wired in parallel will provide 6600mah capacity. I've measured inside the boat and there is loads of room for them. 5s packs look to be about the size limit in the sponsons.

Hi all, new to the forum and just purchased a Blackjack 29 V3.
Question for you, above the on off switch for the esc there is a tiny micro switch, when I push and hold this down the light on the esc starts to flash but I have no idea what this is for, no reference in the instructions.
Could this be for switching the type of battery used like the V2?image.jpg

[helidan]

I asked about the button but nobody seems to know. It's probably for programming but I use a program card.
