Mein wahnsinniger Synergy-Eindecker

I'm going to change a few things around. I'll pull the .125 wire drive out and install a .250 flex shaft for the power trim. I plan to lock a flat ride attitude with a Futaba gyro on the 10PX. I 'm going to start with the 2028 castle drag motor but may switch to something in the 90-100K rpm range. I picked the strut up off ebay for $67.00 . There only 1 or two left according to promise hobby. That's a really good deal for what is here in my opinion.

Wie viele Platten haben Sie entfernt? Sieht so aus, als ob der Stator 50X70 war, was um weitere 5020 mehr Eisen ist als Ihr 5050. Die zusätzliche Leistung, die der 2028 im Vergleich hat, ist offensichtlich. Mit dem großen Monodraht, wie viel Füllung Sie verloren haben, können Sie den ungenutzten Platz dort sehen. Nicht gut für eine optimale Wärmeleitfähigkeit.

You could probably pull off dual 8mm cable into the AMASS SH 8.0 connector but I didn't do that . I'm going to add 8 awg leads finished with castle 6.5mm connectors soldered right into the XLX2 battery input cables so the super caps or any other caps or auxiliary off main power can just plug in . This will also make it easy for use to log the before and after effects of the capacitance on ripple and voltage sag. Once everything is mounted in place maybe I can shorten some of the cables, but I want to maintain modularity so I can interchange all this with other boats setups etc. I'm not worried about voltage drop . I should be stout enough on delivery for whatever. The XLX2 and the HYDRA versions do have the built in spark arrestors.🙏

Thanks for your continued interest in my Insane mono. The swimming pool in Bayern doesn't have enough room Borat. 😜

Again, Here is 2,000,000 uf at 6s lipo or 1,000,000 uf of INSANE capacitance at 12s lipo to compliment the 250C SMC Drag cells.😮 They are about the size and weight of a typical LiFe rx pack. I wired them up just like a pair of saddle packs with 8 AWG castle cable and 6.5 connectors. They have enough capacity to run the inverter without a battery for a short period of time. In short durations they can deliver quite a bit of amperage. This is a long way from the 2000 uf you get from castle in a form factor just slightly larger than their electrolytic cap bank..For cooling with water one of my ideas is to glue a copper strip with tubing soldered to it to the bottom of the exposed barrels with a thermally conductive adhesive or thermal pad. The diagram explains it well. Some may find it overkill but I feel this is critical because the lithium supercaps don't like to be above 70C* you don't want to run into any problems or introduce a short with this amount of current surging through the boat . Id feel a a little better with the investment If I know I'm at least trying to cool them.

Hi,

The 1721 2400 Kv will be sent back to castle. There is no way this one I have in hand does 90,000 rpm. I tested it today on 8s and It is so out of balance at wot im scared to run it long there. I think ill be buying a Neu 1539. Out the box a motor should be smooth as silk at wot. I opened it up and it was nothing that stood out. There was not any trash in the gap. The rotor lost its balance somehow is all I can figure. The balance tabs were in place.

Castle Drag motors aren't covered under warranty but I just called and since I have not run it in a model they said they will look at it and if it's defective they will cover it.

Regards
Hubert

All connectors are not created equal . You know if you get a 20 bag for next to nothing its probably CCA with a higher resistance. That said It matters the connectors you use. I use AMASS and CASTLE.


Thank you.

Here are photos on the scale that show the difference in weight from standard electrolytics versus hybrid caps. The 2 100 volt barrels like you see typical only give you 660uf while the hybrid bank gives you 4700 uf. The 10 px was damaged and had a cracked LCD . Its back now and ready to go. Were getting close..... but I still have to fully configure XLX2 & 2028 telemetry and then the Futaba onboard gyro.

[Clugh]

More caps boys. These are the hybrids and you get alot of capacitance in a much smaller package. Here the radio box model I forgot to show it.

[Clugh]

I wired them up this way because I already have and idea how I want to load them in the boats. Its castle 8 AWG and 6.5mm connectors.

[Clugh]

I'm equally guilty but as American we always talk all this ying yang about Chinese quality and sometimes the quality is low but in the case of Dee in Hong Kong it is not. I don't know what material Dee uses but ETTI hardware has always been some of the best hardware you can get. I wish they made hardware for the really big boats and riggers because the quality is second to none. You never need to break a single edge. It appears apparent in their tool paths because every iota of the items AWAYS have perfect and uniform broken edges. The material is also different grade of Aluminum than you generally see . It is lighter , stronger , and seems to machine to a better finish. I'll have to ask Dee what he using but it is of a very high quality. It was much better than that of the Sweeds at BB. That's the truth directly from what I have in my hands here. I needed to clean up the BB hardware quite a bit.

"Cooling a capacitor helps to enhance its performance as well as its reliability. Cooling will extend its life; taking away more heat from the capacitor can also give it more power-carrying ability. Murray Slovick dig into more details of methods and principles how to cool capacitors in his article published by TTI Market Eye."

The site and PDF can explain things.

ETTI Marine arrived.

[Clugh]

The order is shipped but no one has to go through this. OSE has these banks cheaper and you don't pay a flat rate of 65.00!! I also got two of these because I want to water cool the capacitor bank and these will allow be to do that. Im not sure about the super caps until I have them in hand. In parallel you have 9400uf @ 35 volts in series 4700uf @70 Volts.
But still the super caps in the super cap bank should be able deliver well over 100 amperes at a snap. So ideally that's what I want to cool but this is still alot of bulk electrolytic for its size.

Guess i dont understand the dating system there?

Im also still waiting for a high amperage inverter using BLHELI32 FW and program suite. That would be really really nice .

[Clugh]

I bet you this will be one of the best 6s unit on the market . They know what they are doing if they delivered the past with 8 bits. It has telemetry on the way....

[Clugh]

To get and idea of its internal resistance. The bullet proof castle 200 Ice HV v2 ir is .0011. So to me the etti is a good low resistance controller. I doubt anyone runs them. The marketing is not there and its dated tech but that could have advantage if its a 6 step drive. To me.unless you have a FOC based inverter you'd rather have 6 step drive for high speed efficiency and max torque density in a boat esp. Id really need to see it on the scope because who know with the speed limit ETTI may have a sinus algorithm.

Its also dated in that I dont think it has datalogging. It is programmable though and does not have auto timing. The default is set at 2 degrees.

You can be sure the MCU is nothing like available today but if the castle used a 6800 then it was 8 bit all along....

Say what you want about castle but that tells you that the engineers there are really remarkable in design and coding. Id be scared to see what their new 32bit unit really does. The old castle had the onboard hardware to support active free wheel all along as well.

[Clugh]

The ETTI marine HV ir is .001 Its speed limit on 14 poles is 32,000 rpm but it can do 30 degrees timing and then the 32khz PWM its 315 grams it has water cooling on both bridges
