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

[Rafael_Lopez]

Speed on 15* was just over 50, with the recommended 50c packs. Temps , as you find out can go up between 20-30*.

Personally on my boat, I run lower timing with an x440/3 and get way faster speeds than with high timing; cooler temps as well compared to high timing. I did this change to a customers boat that I met at the pond and he was amazed by the upgrade in performance, even with his 30c Hobby People packs which he said used to get pretty hot before the timing change.

Thanks for the prop tips, never tried a 3 blade prop before, ose is out of stock if i want it sharpen and balanced.
Going to look for this prop and try it out.
But if i only use the stock prop the 15 timing is safe to use or is it a risk to burn the esc on this timing?
Just curious what the gps would tell me if i change the timing to 15 :-)

I pulled the motor out replaced with a leopard 2200kv with 42-55 prop on smc 3cell 60c packs 7.5 degree timing got 65 mph. Esc 120 degrees and motor 102 degrees.not for just cruising around though lol!

[QUOTE=Rafael_Lopez;615744]Hi guys,

I'll chime in here and share some info that might be useful to some of you. This info has come about through development as well as from running my personal boat for fun.

1. My boat is all stock with the exception of having the bottom of the strut even with the ride pads. Prop is stock, not balanced.
2. With the stock timing of 15* I got a best of 50.8 mph with our Dynamite Reaction 80C 5700mah 11.1v packs, 6s. The system draws 80 amps continuous at that voltage/speed.
3. With the timing set to 7.5* the boat ran a best of 45.4 mph with the same packs, but amperage went down to 70 amps continuous, and motor connector temps dropped as well. This option leaves more room to play with props if you want to get back up to 50+, at your own risk.
4. I have found that depending on your battery weight, CG, and playing with the strut angle, you can minimize the bounce of the boat, for specific water conditions. Sometimes I only get a little bounce as it passes over my it's own ripples. I'm not saying blue printing doesn't work. It's just not the only option.

I am running the 50C 3S Reactions. I found that moving the strut all the way down and moving the batteries to the front of the trays, my boat easily cut through the water and did not catch air and flip. I also advanced the timing. My shaft had a slight bend in it which I eventually noticed while cleaning it and once it was removed, the motor realigned to the shaft, added a couple of degrees advance, the boat rips without dancing like it did fresh from the factory. Engine and ESC heat were very minimal but not measured. Wires were NOT HOT. I noted in one of your later posts one of the forum members took issues with the setup over your comments. My experience is much the same as you posted. While I took on a buoy in a turn at near 40 mph cracked the right front hull, a piece of electrical tape kept me running. I run two sets of bats each time I go out and then call it a day. I have also added some yellow cable ties to the battery straps to keep them from sliding under the trays and also to pull them up to re-thread to make battery changes a little easier. 20150924_095519.jpg What I would like to do is add a second water pick up to insure I don't burn up anything while experimenting. I have the GPS meter on order from LHS.

A hairdryer should loosen them up

So the graphics on both of both of these boats r just stickers that can be easily removed? I know on some boats the graphics r under some kind of clear coat.

Thanks

[JimClark]

I think aquacraft does that. I have a geico and I don't think mine are under clearcoat

V2 or V3??

Anybody know which version this is? Black hardware, antenna on port side of boat? I've been searching proboat site, google etc pics and can't seem to find this unicorn.....

Been a long week, thanks!image.jpg

[Rafael_Lopez]

That's a V3. http://www.proboatmodels.com/Product...rodId=PRB08011

[TheShaughnessy]

The square hatch gives it away as a v3 if you want to know what to look for

[pistol18]

Great, thank you both! The black hardware and different antenna pictures are not the same as the proboat website v3 pics, which is what confused me. I understand subtle changes in the product cycle though.

I just purchased a Blackjack V3, I am needing advice on the best prop for 4s running. I also would like a prop for 5s. I would also like to hear about any other upgrades that would use the stock motor esc.

ThankS
Mike

Ther are volumes of info if yo use the search function
