Black Jack 26 Twin

New speed

Congratulations on your new speed, that is outstanding!! put my boat back together I only ever managed to get 47 mph. I then blew it up again and have now put everything back to stock, still runs between 39-44 mph depending on which prop I throw on. But it no longer blows up.

That is wrong and perfect at the same time! I love it!

Once you find some glassy water and play with the struts, maybe throw on a set of sharpened and balanced copper beryllium props you might hit 70.

And I hear you'll hit 80mph if you take the stickers off. Even I know that and I've been RC boating for only two weeks now...

Congratulations on hitting 74 miles an hour that was insane you have your boat running like a dream.

[NitroVal]

Wow, 74mph is insane out of a 26" hull..

WOW nice job

[bwells]

excellent job but I thought we were told the BJ hull is not capable of those speeds! In your last video, you did 3 different props but I only caught the last 2, the 642 and 442. The 442 did 5 mph better than the 642. This reminds me of my big boat that came with a 22 pitch prop and the 4.3 v6 would turn 4200 RPM and do 44 mph but would not get me out of the water on a single until 200 feet( 6 feet , 200lb). I thought that I need to prop down and take the hit on top end to get the hole shot. Slapped on a 19 pitch and got the pull needed and the motor now turns 4700 RPM and does 48 MPH, A win win situation. Thanks for your testing and I,m going to try a 4 series pitch on my BJ26 and increase diameter as needed. Excellent job on that boat and a nice looking lake!

Awesome!

Great Job!

i was wandering ,why did you remove the drivers Canopy ???

[Eggy]

Nice job, didnt think that the BJ26 hull was good for more than mid 60's, but guess i was wrong :P

i was wandering ,why did you remove the drivers Canopy ???

I bet you that the Canopy's have been cracked when he was flipping the boat. I blew over at mid 40's and cracked one canopy, later the same week i blew over again and the second was gone.

[jlr3rd1]

ok true :) i didnt know if it was due to weight or drag? but bet you are right

[mudl]

Hello

thanks for the gratulations.
Cannopy's are broken by a turn over.
I will try to reduce the weight of the boat to drive much faster.At the moment the boat is at 3200 gramms ready to run.And i think its to much.Maybe i can beat 80 mph

I LOVE THIS FRIGGIN BOAT!

I am in the process of building a BJ26, and think I am now going to twins. This thing is awesome!

Thanks for posting it and giving me some new ideas!
