Yes, everything is stock, exept for the esc.

Hi, here is today's run! I think i'm getting somewhere! https://youtu.be/81y4eRw-WK4

Nice! Any changes? I just put an M445 prop on mine and it really woke it up! I'm still on 4s...

Yes, a few changes!
1-i sharpened the stock prop.
2-i moved the COG to 9''3/8 from transom.
3- i place the batts right behind the motor.
and 4- i added foam for more flotation.

i tried the Grimracer 42x55 and got to 61 km/h. With the octure x442, got 58 km/h. i didn't use the gps for the last run, but it looks faster with the sharpened stock prop.

You should try 5s with that boat, it a great adrenalin rush!

How is it going Boilo? Any updates yet?

Well, i received my props!!! And a tested the x443 on 4s, it was a bit slow, around 42kph. Then the x442/3 4s i got 51kph. And after this a ran the x440/3 on 5s for my last run of the day, and a got my NEW SPEED RECORD, 67kph. But on the last run i had to move the batts about 2'' forward, in order to keep it on the water, and even then, it was still a bit too dry. I cant wait to see what it will be with my new esc and motor! I will post the vid here in the video section in a few minutes!

[boilo56]

Here is the complete run not edited. You can skip from 4:50 to 5:40, it is only my cam looking at the grass. https://youtu.be/HLZRM0FBfdA

[boilo56]

Finally, my parts are arrived !!! Look at these beauties!IMG_20150612_175829.jpg I'll test the setup tomorrow, and see what kind of upgrade this will be!

[Turbo Dan-O]

Nice! Why the new ESC? And what are the motor specs?

[boilo56]

Hi, The motor is a 4 pole inrunner, 2200kv, winging 2.5d continuous current 70amp, peak current 100amp max power 1200w. This is what is written on the box.

I'm waiting on my batteries to finish charging to go try this setup!

[boilo56]

The new ESC is 'cause the MM2 need to go back in my Slash 4x4!

[boilo56]

But i tought it would be a good idea to install the traxxas telemetry on it, for voltage and temps!IMG_20150613_115619.jpg

[Turbo Dan-O]

Oh cool! I would love to do something like that. I always thought that had to be "built in" to the ESC.

Edit: Just did a search for it. That is wicked cool! Be sure and post up your results!

[boilo56]

Just got back, I tried the X440/3 and the X443. It was too windy to go WOT, but on the X440/3 i got 70kph at 2/3 throttle. i didn't movitor the speed for the X443, but it looks crazy fast!https://youtu.be/s089W3KTqoEIMG_20150613_133425.jpg

[boilo56]

I have some problems with my new ESC. The led starts blinking after a few minutes of use. The batteries were full. See what i meanhttps://youtu.be/zb6Ifl_HHQU Please some help would be very appreciated!

Hi went running the boat again, everything was fine! Here is the first complete run:

[boilo56]

Here is the second run:

Here is the third run:

[boilo56]

And here is my last run of the day:
I wasn't able to go WOT on the first pass.

With the front of the boat coming up like it is it looks like you have to much positive angle on the stinger ( angled up to much prop end ) or the centre of gravity is to far back.

[boilo56]

Good thing to know, i was thinking of lowering the trimtabs a bit, but adjusting the stigner angle seem easier. Thank you for your input!

[boilo56]

But it was so cool to see it riding only on the prop like that!!! I will try it again some time!6-14-2015_003.jpg

Also, the COG is around 9''1/2 from transom. Batts were far in front.

[martin]

Cg needs to be around 9.75" in from transom as a starting point, re stinger & tabs angle start with them neutral ( parallel with the hull bottom ) & then adjust as needed.

[boilo56]

The trim tabs are at ''0''. Stigner is around 1 to 1.5 degrees positive from factory. Maybe if i move the ESC right behind the motor. Would it help the COG?

[martin]

Your cg is not far out, moving the esc back would help but I would take a bit out of the stinger angle & run again.
