New HK Mono

[hookedup]

It would be nice if they sold the motor separate as a repair item or something? The 36x60 one that is.

i know right?? kinda weird that this motor is in a few of their new boats, and they dont sell it just by itself.

[ray schrauwen]

They might. I noticed they sell some replacement parts.

HOR Racing sell some of the black TFL motors as their SSS series. I have a couple & they run strong & cool.

Here's my Outer Limits maiden run. All stock except the prop which is a 440/3 blade. After the run the motor, batteries & ESC were only 'Tepid'. Barely warm. I did run an M445 on it too but it was more unstable in the turns. But again there was no temperature in the motor, ESC, or batteries.
There's heaps more speed in it yet. But I'll have to learn how to set up a stepped hull properly first. Especially the turn fin. It's set up vertical like the rudder. A common practice in Europe & Asia with stepped hulls from what I've seen. The turns get very skippy if I tried to turn too tightly.
Any info on setting up a stepped hull would be greatly appreciated. Stinger angle, COG, turn fin, etc.

Looks like it running pretty good,
May be if you tilt the rudder in 1/8" that will help a little in the turns with the skipping.
Have any pictures of the setup and cell placement,
Also setting on hardware you just ran ?

I would make the turn fin perpendicular to the bottom. My El Lobo IV skipped in the turns until I got the setup right and I fried a couple ESC's in the process. As lenny said moving the rudder in a bit will help to plant the stern.

Thanks for the tips guys. I will certainly be trying that today.

Set up on that run was as it came out of the box.
Stinger Parallel with the last step. I've since read that it should be parallel with a line drawn from the first step to the transom. This will effectively put a bit of positive into it, in relation to where it is now.
Turn fin vertical and as deep as it would go.
COG. The pack was run where it is shown in the first pic. This made it 32% from the transom.(not the back of the boat). It's the black mark on the side hatch lines. The transom is actually level with the rear hatch line
If I put the COG at just in front of the first step, the battery needs to be where it is shown in the second pic. That makes it 37% from the transom. The forward black line on the side hatch lines.
I bought this because I've never done a stepped hull & this thing just looked so good. And I've got to say It is well put together & beautifully finished.
The only draw back is the brittle hot glue type stuff they use to fit the motor mounts & trays. They don't scuff the glass or wipe the 'waxy' finish off with a bit of Acetone before gluing anything in. The battery tray in mine had come adrift in transit.
That's why I epoxy some carbon rods in along the join lines in all of these types of boats.
As always, any help will be appreciated.

thanks for the pics and stuff, im thinking about getting one of these to replace my persuit that I hate. Not sure If i want to get this one or the smash shark.
I like the hatch on these boats compared to the persuit, they are flat where they join the deck of the boat, so taping them up works a lot better.
I know these boats are cheap and flimsy, but for the cost of re enforcing one of these, they are worth it!

[ray schrauwen]

Does the flex shaft come out the stinger or is it the square drive captivated type drive line?

[iamandrew]

I think its a 3/16 square drive 2 piece

[785boats]

Ray.
Yes. It is the two part drive but the beauty of this one is that the flex & the stub are both 3/16". So putting a welded flex & stub shaft in will be a piece of cake.

Andrew.
The hull itself isn't flimsy at all. It's really quite tough. The steps really stiffen up the bottom of the hull.
How can you hate the Pursuit? They are a great handling boat. Much better than this one (so far).
I'd be interested to see how the Smash Shark handles.

I tried out a few changes last Saturday but made the handling worse. After angling the turn fin out to be perpendicular to the bottom of the hull instead of parallel with the rudder, the boat spun out too easily in a sharp turn. Changing COG or stinger angle didn't help.

But that motor ended up spinning an M447 prop with ease to give the thing a good turn of speed. Still nothing got hot.
Those TFL motors are really powerful little beasts. I've got a 4074 2200kv & a 3674 2075Kv motor & they are the same...strong & cool running

Cheers.

How sharp of a turn? Sharper than the buoys on a oval race course? You may need a larger turn fin.

[Tunda]

Did you run that m447 prop on 4s?

[785boats]

egneg.
It does get around the turns at our larger race course at our other lake. But the course in video, in my first post, is much tighter & I can't get around it as tightly as I can with any of my 'normal' race monos. Yet.

One problem I feel, is that the turnfin bracket is mounted about an inch inside the chine on the transom. There's no room to move it out to the chine as the bracket will be dragging in the water. The transom between the bottom of the hull & the overhang is too narrow. I might try to jig something up there. But I was also thinking of trying a bargeboard turn fin like I've seen some European set ups have.

Tunda.
Yep. That's a 4s boat.

[iamandrew]

So its not possible to make the turn fin bracket higher?

[Tunda]

Got mine ready to test also thanks for the info. I was going to try it with the stock flex shaft set up but decided to change to a 150 cable it was simple to do the 150 liner fits inside of the stock liner and put it back in the stock stuffing tube thats it.........150 cable with 3/16 prop shaft.
