Proboat release new Blackjack 42" catamaran

[Panther6834]

Could be, I have a couple of Spektrum equipped cars with gyros but adjustments are made on the radio.

Adjustments are done from the Tx...but, the 'gyro' (called 'AVC' by Spektrum) is built their RCs.

Black Jack 42 / Day 2 of testing

Took her out yesterday for the Maiden run but only took it out on 6s, since I did not have a recovery boat or a Kayak with me at the lake. All in all in ran very nice on 6s - i did not have any Heat issues or any other issues with the front popping up but then I again I was on 6s.. Today, I will be trying out my new pair of 4s - HRB 6000maH 14.2v 50c lipos and really see what this boat has with everything bone stock. Before I start dialing my boat in and switch over to a new Dasboata Prop.. (TIP) I have been hearing a lot of people says that they have having problems w/ the front end popping up when they hit the throttle when running on 8s. How I fixed that problem was I simply added an extra pool noodle towards the front of the boat and made sure that it a tight fit from side to side so I can add about 4 ounces of weight and I have it stuffed in my pool noodle and it seems to keeps the front end down for me quite well..

I will be recording my boat session today so it will be available for your review on my Youtube channel.
Make sure you click the subscribe button since i will be posting more videos on different Dashboata props that Chris Hoffman made for my Sonicwake36 that i will be testing out..
My PB w/ my Sonicwake36 was 65mph and that was when I was running the the Sonice3prop from Dasboata...It's going to be very interesting to see what type of Top End speed I can get with my BJ42 running on 8s with the Supersonic3 prop..

How you fix that issues is I simply just added 2 200 gram weights and stuffed them up under my styrofoam that's in the front of the boat and it seems to keeps the front end down for me quite well..

Wow, thats nearly a full pound of extra weight! Hopefully some carefull set-up will be able to tune the bounce out. I look forward to seeing your youtube vid.

FYI whoever asked about the rudder slop, yes mine has it as well. Noticed it as soon as I took it out of the box and thought it was odd but apparently it is normal.

Can't wait to see your vid. Will be interesting to see how your added weight affects the boat.

ProBoat Blackjack 42'' 8s (High Performance Speed Boat) Maiden Run

Here was my Maiden run yesterday without any weights and 100 % stock..

Here was my Maiden run yesterday without any weights in it and 100 % stock.

Looks good...but, as expected, "hopping like a kangaroo" at full throttle. It's looking more & more like ProBoat/Horizon Hobby 'failed' on this one. I'm sure all (or, at least, almost all) BJ42 owners will figure out ways of making 'adjustments' to make her stable...but, honestly, a boat just out of the box should NOT need so many 'adjustments' just to be able to run it. This would be like buying a BMW, Mercedes, Ferrari, etc, and finding out you have to keep it below 55mph, or the car will become unstable.

I'm beginning to wonder if this is due to having used Lexan for the hull. Even though it's has all that bracing, is probably still not enough to completely keep the hull from flexing...and, if such is the case, the hull is probably flexing every time the boat hops. Sorry, Horizon Hobby, but this is NOT acceptable.

Some minor adjustments and this baby will be flying like a missle over the water.

I have run this boat twice and there was some hop not crazy. You cant hold full throttle at almost top speed for more than 1.5sec. I was having blow over issues. I think i will try putting the strut down some from where it was out of the box i am also running 2 zeee 4s 9000mah 100c batteries and they have some weight to them.

Just installed rubberized battery straps hope that helps my batteries came loose after a couple flips

How can you say "there was some hop not crazy", and then follow that up by admitting "You cant hold full throttle at almost top speed for more than 1.5sec"? If there was no problem, you should be able to hold full throttle continuously.

Ok so i take it back then i guess it hops. I just thought it wasn?t as bad as some were making it out to be.

And im still a newb i have only been boating for two years when i get a chance.

But ya compared to my sonicwake and miss gieco it hops

I have a blackjack 42, 2weeks now. I hit a goose @50 mph here is what happened, good didn't make it20210615_003142.jpg20210615_003142.jpg

IM also having trouble with the Strut bushing less than 6 sets of packs and bushing is wallowing out. Plenty of grease after each set of packs.

What happen did you goose it and it flipped over and damaged the Hull?
See I am going to start off with around 100 grams of weight towards the front of my boat and stuff it up under the styrofoam and see if that will keep the front end down.
I will be making another video this weekend and hopefully by adding a some weight towards the front that it will fix the hopping problem..

No...I think he, literally, meant he hit a goose - as in, be killed a bird with his boat (unintentionally...at least, I'd hope it wasn't intentional).

Yes I accidentally killed a goose with the 42. A dog run a small flock of geese into the pond I looked both ways before I pulled the trigger and boom hit the goose at "50knots with no smoke" sorry about last post I'm getting use to this whole forum layout.. 16237728122298762448810287230180.jpg

I posted on youtube as a public safety announcement. these boats are fast so be safe with these big fast boats

I want this boat to work but damn it's tough. It's weird how I can make a pass one way and it hops like crazy and when you go the opposite way it stays planted? I think you can shove an anchor in this hull and it'll still bounce..lol. What I hate the most is how much I have to work the throttle to keep it from bouncing. I know PB reads these forums so I expect a V2 sooner than later.
