Great up grade kit for the black Jack 42, now I have cooler temps & and the trim tabs really helped with blow over’s. And considering how far the kit had to come shipping was very fast. And also the prop that comes with the kit really works well on the 42.
Great kit I highly recommend it.

I got 14 mph on my stock setup after installing the prop. I set up the trim tabs with the stock prop. Then put on the RC prop on and was impressed.

Great upgrade kit. The trim tabs do a great job of keeping the front of the boat down when doing some high speed runs. Play with your battery placement to find just the right spot to balance it out. Also, I really like the cooling upgrade. Drilling the holes for the placement of the cooling hose outlets and the trim tabs is not a big deal. Just take your time in drilling the holes (measure 3X, drill once). I used a marine silicone for a good seal around where I drilled the holes. RC Boat Bitz has some good videos for installing the trim tabs and cooling hoses. Again, not a big deal installing this kit and certainly worth it.

With this upgrade it totally tames the black jack 42 and it allowed me to hit 100kmh and had no flips! ESC and engine temps are down too! A must upgrade for the black jack 42!
