Thanks heaps for the video mate. I’m just about to start planning my build and was so worried about the hydraulic work. After watching this video I feel that I can now proceed. Cheers Robert 😊
@aussiegolddogcnc3d412 Thanks for your kind feedback Robert! Nice to hear that the videos acutally really help you. Good luck and have fun with your new project! cheers
Hello Sebbe23 Thank you for making this video and also for thinking of the only English speaking people like myself. It includes allot of information. Thanks again. Cheers Willy
Thanks for the video. Is it better to have the pressure relief valve just after the pump or where you got it in your diagram? Or doesnt matter at all? What kind of threadlock did you use for the hydraulics? Any suggestions? Ah the Answer is in the Description :).
I usually try to assamble the hydraulic system exactly how it is shown in the diagram, to have a constant flow of hydraulic fluid throughout the whole system. However I've also seen and built machines that have the PRV directly at the pump. Those also ran fine. BTW this would also be the case if you are using a pump with integrated PRV. So I don't have a real proof that one ore the other runs better. In the end other aspects like programming, mixing and the physical layout of tank, pump and hoses will play a much bigger role on the performance of the system Threadlock: Loctite 542 - as you have already seen in the description ;-)
Hi, thank you for this valuable lessons. Can you please recommend type of hydraulic Oil ? is HLP22 (ISO VG 22) good enough, or not recommended at all ?
You might include it in the low-pressure line between filter and tank (or maybe prv and tank). It depends a bit why your oil is too hot in the first place. If it's too hot because of the pump pushing too much oil through the prv in idle, you should considre fixing this first - lower idle rpm. Generelly, I don't think a radiator is really neccessary for most models. Usually the oil becomes too hot due to wrong hydraulic setup or (mainly) wrong programming, which can be easily corrected. If you just like to have a radiaor in your system, just add it like mentioned ;-)
@@sebbe23 thank you. It was such an interesting video and many questions spring to mind relating to the hydraulics. I don’t have a radiator, and the model uses a combined tank and pump . Im not sure how you would check the temperature or know what a reasonable temperature would be. 🤔. Having had hoses expand recently I guess something isn’t quite right🙈.
@@witneydiggersrc3251 with this all included units it's sometimes quite hard to really improve it. That's why I try to use seperate pump, thank, prv etc. If it's hot to the touch then it is too hot. If the hose burts then it underlines that its too hot or the pressure is too high (or both). Try lowering the idle rpm and try lowering the pressure. Often much less is needed then one thinks. This will be addressed in the nex episode that will hopefully come out in some time 👍 cheers
@ErichPeschka hängt ganz vom Modell ab. Ich habe bisher nur 1:14,5 gebaut. Habe 1:8er gesehen, die identische Technik nutzen wie im Video genzeigt, aber auch welche die kleine Industrie-Komponenten benutzen. Es kommt ganz darauf an, welchen Druck du fahren möchtest und wieviel Volumenstrom du brauchst.
Very good question, thank you! If you take a look at the actual cross section, a hose with 2,5mm inner diameter has a 56% bigger (!) cross sections compared to a 2mm hose ( PI*R²: 3,14 * (2/2)² = 3,1mm² vs 3,14 * (2,5/2)² = 4,9mm²). Also the max pressure is usually stated at room temp (20°C). With hot oil (e.g. 60°C) the strenght can reduce significantly! So better don't take for granted that you can use that hose at 60bar all the time! Also, from my point of view, you don't need that high pressure in a model. I'll discuss this topic in detail in the next (8th) episode.
since there should be no pressure, you should be able to use what you like. However, if the programming of the model is done right there souldn't be much oil going through the PRV, so a bigger diameter will not benefit. I use 4x2.5 for all standard connections (except for tank pump)
jede Funktion benötigt ein Ventil. Es ist egal, wie viele Zylinder für eine Funktion benutzt werden. z.B. 2 Hubzylinder vom Hauptarm werden über ein Ventil angesteuert
@@sebbe23 ok ja sonst ist gut oder schlecht das ein ventil bei haupt arm des 2 zylinder betreiben bzw steuern kann sein das zu wenieg kraft ode zu langsam sein 😉
This is awesome im so glad I found this video! I needed the info for my next custom rc build. Thank you!
I’m new to the RC construction hobby and this was super helpful. Thanks for posting. I’ve subscribed and thumbs up!
Thanks for your kind feedback!
I enjoyed your well explained video.thanks for taking the time to make it. Lovely model
Hi Sebastian, wieder ein tolles, lehrreiches Video. Dankeschön!👍
Wow... I was looking a detailed video since 5 years... Glad i found it... Keep it up brother..
Super das Du Dir die Mühe für diese erstklassige Videoserie machst. Zweisprachig finde ich toll und Bildqualität sowie Erklärungen sind spitze
@larsthiede1130 vielen Dank!
AWESOME!!!, Thank you for the super detailed information!
Hallo, mega Video, alles bestens erklärt. Welche Dosierspitze benutzen Sie für das Auftragen auf die Gewinde?
Viele Grüße
@flexi6385 vielen Dank! Das ist eine ~0,5mm Dosierspitze
@@sebbe23 alles klar, dankeschön

Hello Willy, thank you very much for your kind feedback. It's always nice to hear that these videos are actually helpful. Cheers - Sebastian
nice
Jo danke! Hilft mir bei meinem nächsten RC Boot Projekt (ac40)

Thank you very much for your feedback! I use HLP22, it is used in all PREMACON machines. so it is perfectly fine
@@sebbe23 Thanks a million for quick answer! Looking forward for new episodes...
Very helpful. Although you didn’t include the radiator as mentioned it would of been nice to see.

Onde comprou esse conjunto de válvulas me passa o link por favor, gostei do tamanho e é muito prático também
valve and model itself are from premacon.com
@@sebbe23 obrigado 🙏
Dimana bisa saya membeli alat nya
the relief valve need to be before hydraulik valveblock ,or
just somewhere in the high-pressure line that comes from the tank
hallo braucht mittlere motor und seitliche motoren von kette ein fahrtregler oder
jeder motor braut einen eigenen Fahrtregler
Welche Größe bzw. Stärke sollten Motor, Pumpe, Ventile und Schläuche bei einem 1:8er RC-Modell haben?

My question is if I run a oil cooler where does it connect in the system??
in the low pressure line before it goes back to the tank
Hi
I'm wondering if I'm using hose 4x2 is big difference between 4x2.5??
My hose 4x2 withstand pressure up to 60 bar
Very good question, thank you! If you take a look at the actual cross section, a hose with 2,5mm inner diameter has a 56% bigger (!) cross sections compared to a 2mm hose ( PI*R²: 3,14 * (2/2)² = 3,1mm² vs 3,14 * (2,5/2)² = 4,9mm²).

Hi
what size of hose should be at the outlet of the pressure relief valve ??
4x2.5 or 6x4 ??
since there should be no pressure, you should be able to use what you like. However, if the programming of the model is done right there souldn't be much oil going through the PRV, so a bigger diameter will not benefit. I use 4x2.5 for all standard connections (except for tank pump)
@@sebbe23 hallo das ich nicht so gutt englisch verstehe, welche schlauch soll benutzen von tank bis zum hydraulik pumpe und zu ventilblock, Danke Mfg
ist gut das ein ventil steuern zwei zylinder wie hier in wideo oder soll jede zylinder ein ventil ventil haben ,wie ist am bestens
jede Funktion benötigt ein Ventil. Es ist egal, wie viele Zylinder für eine Funktion benutzt werden. z.B. 2 Hubzylinder vom Hauptarm werden über ein Ventil angesteuert
@@sebbe23 ok ja sonst ist gut oder schlecht das ein ventil bei haupt arm des 2 zylinder betreiben bzw steuern kann sein das zu wenieg kraft ode zu langsam sein 😉
Weil deswegen ich frage was ist besser 2 ventilen auf 2 zylinder oder 1 ventil auf 2 zyl, bei hauptarm
@@yasons9531 benutze 1 ventil für 2 Zylinder am Hauptarm.
@@sebbe23 super danke mache ich, Mfg
