HK Genesis Build/Help

Your rudder is roughly in the same position as mine, but I run the stock blade with the offset bracket. I don't have issues with tracking once the steering was trimmed out. What prop are you running with the new motor? I noticed low speed stability issues before the hull was fully on plane when I tried a small diameter, higher pitch prop vs. the larger diameter, lower pitch prop I ended up with.

Right now I'm using Octura X445 and X645 props. I also have this 48mm CNC prop https://www.offshoreelectrics.com/pr...od=cnc-4814250 that I haven't tried yet.

I've run nothing but ABC props on mine, which have significantly noticeable less lift at the transom than the Octura style props. I'm no expert on setup, but I do know that the optimal strut height and trim angle would likely be different between our two setups. By default, you might try a little positive trim angle to help lift the front of the hull, which might be running too low and causing steering issues. The di-hedral style hulls definitely behave differently at slower speeds than those with flat ride pads, and prefer to get up and go before stability sets in.

When the hull gets onto plane and I start to get to full throttle, it seems to not track very strait or stable.

My Genesis is setup for saw runs (same motor as you ) and it gets a little a little unstable after getting on plane, instead of making adjustments to tame it down it slows it down so trying putting a little left turn into it when you get on plane this will bring down the left sponson and then you can pour on the throttle

its the torque roll off that large prop and skinny hull, I also use the offset bracket and it also improves performance....you may also notice you dont have to do this in choppy water that this hull loves because that chop touches that left sponson and keeps it planted

good luck!

I have a Genesis and it's amazing with a little bit of work. A few mods and tuning & you will have a nice performing boat.

I run mine with 2x 6S packs in parallel.
ESC - SeaKing 180Amp V3
Motor - Leopard 1800kv

One of the best mods that you can do that hull is fill in the empty pockets on the back of the hull as they catch water and can cause speed issues and twitchy handling. Once i filled these in the boat became much much much better!!!! I also recommend filling the tips with some carbon powder and epoxy to help. I also run added Carbon Fiber 350mm battery trays on each side. This helped stiffen up the hull greatly!


For props i would say it really depends on what type of running you are doing. I run a CNC 42mm 1.9 pitch and it's perfect for just cruising around. Decent speed & temps after a 7min run ESC/Motor/Batteries all come off around 110-115 degrees. If i am doing just speed passes and getting crazy I run a 48mm 1.9 pitch. This prop i only use for speed runs though as after a few passes things start heating up quick. Really it's just a matter of what you are looking for in the boat with your prop selection. I would just recommend being very diligent about checking temperature of all electronics as you adjust and change props / setups.

What kind of 6S battery do you run?
I ask this because 6S 5000mAh batteries are too big for the Genesis.

[Thunder29]

Turnigy Heavy Duty 4000mah 65-100C 6S packs.

Here is a link to the hobbyking website showing the exact packs.

They fit perfectly. And running a pair of these in parallel makes for a great setup. Not the best pic's I took these in a hurry to show you.

By the way. These Turnigy Heavy Duty batteries are some of the best i've run in boats. I haven't found any other brands of packs that hold up as well as these guys. Especially for the price they are a knock out deal

[Alfa Spirit]

Ok,

4000mAh batteries is the max. 6S size for the Genesis.

5S is the optimal choice for the Genesis hull IMHO. Anyway this Mystic hull is awesome

[Thunder29]

I also run some 5500mah 5S packs. They fit almost exactly the same as the 6S 4000mah.

And i completely agree this hull is really nice with just a few mods and a good setup.

I had that same torque lift on the left side when I started going up in prop sizes. Cured it by moving the left side battery forward a half inch at a time till it stopped torquing over and it planes level now.

Alright,

I did some upgrades to my Genesis. I installed a new TP 4060 Motor 1650Kv 6D wind, and a Seaking 180A ESC. I also made the battery trays longer, giving me more adjustment to the rear. I'm running this setup on 6s, but am disappointed with the results. While the boat is quite fast and has great acceleration, I still feel that the hull runs too wet. I have not once had to worry about the hull flipping from running too dry. I have had the strut at a raised position, I'd say about 3mm up, but maybe I've gone too far? On my last run I adjusted the strut angle so that the front of the prop pointed into the water more, and this made the hull run better, but still wetter than it should run. I've been using Octura X445 and X645, and am planning on getting some ABC props next.

With the new motor and ESC, the hull currently weighs 111oz, and the center of weight is at 31.8% before batteries. I had to make my battery trays longer to put the weight farther back, and I feel like with the batteries in the back this thing should be trying to flip over? Anybody have advise for what I should try, or what I may be doing wrong. I admit that my batteries are not the best, and I'll need to get a higher C rated battery next, but I'm kinda lost at this point.

[MadProps]

still too wet, more positive trim, I had to file my strut to get enough adjustment

check your private messages..... I have a video I made to setup the genesis for another guy ..
hope it helps it should run with an attitude like this when you have enough positive trim... running an octura prop

[fweasel]

ABC props have much less lift at the transom than the Octuras. Switching to a 17-45 series prop will dramatically improve your ride attitude situation. I run a 1915 prop on my 6S and 8S setups.
