    Hi Nice build of the battery. I think you are right, if they are dropping by 2V, with a load of just 20-30A, they are not really suitable for a higher load like 150A it more. What are the specs from the manufacturer? Bye Fabian

    Electric Surf Board

    Hi Chris Both would be fine for me and a big help. Actually I have an offer from China 1200$ for an Impeller because of the complex geometry (CNC). Maybe I am actually doing an overengineered solution. I am really interested in looking at your files. My private E-Mail...

    Electric Surf Board

    I am trying to build up a pump. The problem is the CFD actually...I am not sure where to start. Second, I have already tried to print one in metal. Big fail because of the supports, needed to build up the impeller. Which diameter are you using? What are the main specs? Maybe it is possible to...

    Once again, big congrats from my side. Good job, nice ride, cool video and a nice spot. I would like to talk to you about your jetpump. If it would be ok for you :D

    One question: When I have printed something from metal there was a shrinkage. I have checked i.materialise.com what was the shrinkage there? I think this is still something unknown with steel?

    Hi Chris To ask for a est. prize I need the building volume...or something like this. But the metal parts are really expensive. What about CNC?

    Cool, I have seen it already. Are you buying the defect Jetsurf?

    Electric Surf Board

    That sounds cool, I am trying to animate a PhD in fluid technical systems and my old connections to Formula1. I think building up a jet is not impossible. The hardest thing is spending money for the itereations and the prototypes. By the way, we have multi jet HP printer and also some DMLS metal...

    I also think, that the jetpump could be optimized e.g. more pitch. Has anyone optimized the MHZ Jet? I am also trying to build up a pump for 80mm, a target rpm 8000-9000....anyone interested

    Electric Surf Board

    Yes, you are right. The battery is the bottleneck. It is not so easy to find a lightweight solution with a high output. But at the meantime I am really thinking about to sell all the stuff...my partner is going mad with the first 2 boards hanging around and the actual one which is in our guest...

    Hi It is the MGM 250-63 HBC - industrial version. It is more or less the same like the 400-63 RC version. The jetpump is a modified 64 MHZ version. By Fabian

    Okay so the motors are more or less the same from their behaviour

    Chris which kind of motor is your actual model? I will try that timing setting the next weekend. I am really looking forward to see an influence. If you are interested in such a battery, let mw know. I am thinking about to buy a 30Ah version. So as a light back up. The 53 for the holidays and...

    At the moment I am using 15 degrees. What timing have you set up? The battery was with a special prize 2000 Euros for 17 cells. But add on there is the BMS, which is nearly 600 Euros. So not a cheap solution. Have you installed an additional waterpump?
