I've had it for a week now, been to the lake four times. I ran it just as it was out of the box and had no issues at all. Fun with 6 cell nimh, more fun on 2s lipo, but a 3s lipo wakes up the monster lurking within. I did change the plastic prop to a stainless steel Prather 220 but that's all I changed. I put my Android phone inside with a gps speedometer app and it recorded a top speed of 33 mph. I love the way it handles. It even handles choppy water on a very windy day fairly well, just stay away from 3s batteries when the wind is high. With 3s battery, take off gently or it will launch straight out of the water! High quality 3s battery is a must. I'm running the Dynamite Platinum 5200 mah 50c 3s lipo. I mostly run 2s lipos to be closer competition with my son's ProBoat Stealthwake (another excellent boat). It runs about 22-24 mph on 2s lipo, but when I drop in the 3s, it leaves the Stealthwake like it's tied off to the pier. The Stealthwake handles rough water better though. I did break the hatch cover on the second day out. The wind blew it off the table and it landed on the rear corner and shattered the whole corner. A little more fragile that I would have thought, but the hull seems to be pretty tough. I never was a big fan of catamaran hulls, but the Blackjack changed that. In all, the Blackjack 24 is hands down, my favorite boat.

My review is based off of 10 packs of a venom 3s 4000 mah 30c lipo ran though the blackjack 24

Pros
Very fast
Handles amazing
Never once over heated
Looks great
Great interior design plenty of room for upgrades
Only a few drops of water after each pack
Flex shelf runs sooo smooth
A good size boat that can handle some chop with out being uncontrollable

Cons
Flex shaft needed more grease out of the box
Esc had fallen off in shipping
The rubber pin was jammed from the factory some lock tight had dripped down it

Overall this boat is a great purchase at a great price only a few minor details The pros heavily out way the cons. I would recommend this boat to any looking to have a great time.

I got this as my first boat and I love it. I have a 2s 5000 100c and a 3s 5000 100c battery that I use for it. The 2s is great to get a grasp of how the boat handles and performs. Then the 3s is where you can really push it. It flies off the water and boasts a lot of power. I believe its great for beginners because it stays glued to the water. And on my 3s 5000 100c it easily pushed 35 mph stock as advertised. In conclusion I highly recommend this boat to anyone. Great job horizon/proboat.

Yea I just ran my Brand New pro boat Black jack today and it was alot of fun the 2000kv brushless motor that came with it has alot of power it can handle up to a 4s lipo battery with a 120 amp sea king esc speed controler.my opion is do not run a 6s lipo its too much for the blackjack 24 but its plenty fast with a 4s lipo.this boat is a alot of fun to play with.with a couple of up grades being done 2 it has well.so im looking forward 2 the summer.its going to be fun boat racing with my buddys.

I read reviews on here prior to receiving my boat. When I got it everything was tight, however I still removed the flex shaft and put marine grease on it by hand. I don't see a need for the gun. I tightened everything back up and ran it through two batteries the very first time out. It went about 30' away and started to glitch. The radio I received seemed less quality than the boat to say the least. We kept it close to us and the shore and ran through it's maiden voyage. No issues with the boat. Replaced the radio with the Spektrum DX4 and the receiver that comes with that radio. Unbelievable how far away it works now. I also replace the servo at the same time and put a stainless prop on. My son and I have had it out 10 times at least and it is super. Also, the 3s is the way to go. If I knew then what I know now I would only have bought 3s batteries. 30C is just fine too. Final note, as long as you are smart with it and maintain it thoroughly you'll be amazed. This is a great boat.
