lykke til anbjørn :)
also known as good luck for the non norwegians in here :)

Thanks guys

Well the first test is done and I must say it went far beyond my expectations.
The boat is extremely fast and handles like a dream.
It turns crazy fast.
After lowering the tabs until level with the hull line it is very stable.
However the speed is out of another world
I barely dared to go past 70% trottle for a second or two.
I have the LVC set to 3.0V as pr Hyperion's instructions.
However after 5 min or so running without a cut off I decided to stop running.
After charging I found that each pack have been drained 4400-4500 out of 5500mAh. That is on the limit and I think I should increase the LVC to 3.2V
Temps where very low, below 50 degree C on the motor (118F), esc about 40 (104F), and batteries about 40 (40F)
The drive line hold up fine and when inspecting everything after running there is nothing that needs improvement.
I have the CG at 33,5% but I think I might need to go past 35%

I tried to connect to the esc to download the info from the run but I could not connect to it.
Anyone have a detailed description of how to install on PC and access the data on the esc?
I do have some video, but the files are very big (HD) so I don't know where to host them.
Atleast some blury pictures.

anbjorn...great job.. i am doing one of these myself..what are you getting for speeds with the x460 so far?

[Jacked1]

Can't wait to see you put the hammer down and get a speed reading!

Awesome Anbjørn, good to hear her maiden run was a hit.

I also had problems trying to directly communicate between the 40.303 and the PC. I have not yet tried the 5V-ISO cable only the direct USB (its an air controller)

For the videos, I would suggest youtube of Vimeo.

Anbjorn,

Have you tried hooking a computer up the the Schulze yet? I am unable to view anything on the 40.303, but the 40.160 and 32.200 work fine. Just curoius.

Yes I have tried but no success.

Curious for seeing that monster in action


Altough schulze released a new firmware version, V05, for the 40-160 and for the 32 200, that allowed again the logging of the amp draw, it is everything less then accurate!!!

For having an idea, when the eagle tree measures 185 amp with mine DF35,5 with the NEU 1527 1.5D and an M447 cupped prop, the schulze logs a maximum of 50AMP...
Tell me about precision...it´s more then 300% inacurate

don´t get based on the amp draw logged bu the speed controller..or everything will go on fire.....

[Anbjorn]

Based on the temps after the test I believe I am well within amp limits, atleast for the esc and batteries.
I have not tried to give it full trottle yet as I am sure it would take off.
Will ned a CG of minimum 35% to dare to go past 70% trottle.
I assume temps will go up when I am able to go up in speed.
I would estimate the speed yesterday to be minimum 70-75mph

Cool if somebody could point me in the right direction for a good logging setup.
I have been looking at the Eagle Tree website for suitable equipment.

Awesome job so far Anbjorn . I use the Eagle tree system I would imagine ordering from here would be closer for you...http://www.hobbycity.com/hobbycity/s...&ParentCat=172

Here is a picture of my Eagle tree setup

Garado and Anbjorn,

I did a little test last night with three Schulze(40.160, 32.200 and 40.303). The 40.160 and the 32.200 hook up to USB adapter and interface with the computer no problem. I can download logged data and make any changes to the software(although I don't change anything for fear of pooooof). When I hook up the 40.303, nothing comes up in the main box, however the hyperterminal screen on the right does show it connected. A little odd, but I will contact Schulze to see if we can sort the problem out.

As for the datalogger I am not sure if you want the eLogger V3 with external current sensor or if you want the boat one you mentioned above. Eagle Tree does have a 300 Amp current sensor which looks large enough to squeeze both 6mm wires through if you have enough room to do it.


Peter, were you only mesuring one half of the batteries(1P of 2P) and what kind of currents were you seeing?

Ideally, the Schulze should log all that data.

I was spiking to 135 amps per side Tyler but I was going a little past there 100 amp limit so I cannot vouch for exact accuracy

[RaceMechaniX]

I had a feeling that was the case, but good to know.

once up to speed the current levels off to about 80 amps per side , I was using 20/30 cells and pushing them to the raged edge , best speed to date is 72mph on 2 X 11C packs , betters cells and more prop and 80mph I believe is within reach . this is an incredable hull for high speed stability
