CS8 to X8 conversion - Herkules ESC III V3

[RyanMcCrae]

Why do you need vibration dampening on the herk board? Does it help some how?

 

[BorisS]

Ryan there is not real need. At the same time the dampeners are there and don't weigh a lot so why not use them for that ! On the other side yes every component will be happy to be isolated from vibrations.

Sorry haven't answered you PM yet will get to it tonite

Fair enough, it cant hurt by isolating them. If you didn't have the cs dampners, would you go to the trouble of adding dampeners to the board?
Thanks for that.

Nah too much hassle, but use something like this.

Okay started with the placement of the WKM components and installing the Herks with the ribon cable and the micro match to servo plug converter.

Since the herks are placed under the center plate the ribbon cables are a bit long. I shielded them with cat 7 foil. Micromatch plug in the herks
are hot glued in case some vibs hit the boards and cause the micro match plugs to loosen. Elkos like said fixated with silicon.

Hmm parts are dirty think time for a cleaning session.

If i finally had my parts i could start placing the RX and the LED and give it a test flight hmm but still have to wait.

hmm not enough space for the herks. Have to shorten the standoffs and mount the herks close. And the parts attaching the frame to the landing gear will be long in the final version so additional space.

Damm its a heavy bird already

With that motors Boris u can put 3x Zenmuse on it and still u will lift them easy.

 

[BorisS]

krleas, I am a little worried out the center plates of the CS8 to take extra loads and yes I want to do payload test up to 12 kg full setup. Should I have any worries like support the center plates ?

Thanks

Boris for heavy lifting CS we always use 2 bottom plates. So 1 on top and 2 on bottom.

 

[BorisS]

Okay cool thanks gonna order one !

[BorisS]

At least the material for the made parts arrived This 6mm carbon plate is massive !

6mm?? Do u making a space ship?

 

[BorisS]

close to a spaceship I guess No only for the holders on the side the adapters for the s800 landdingear and Zenmuse.

I made a big mistaken and told my nieces to give the bird a name. Now its called flower ;(

like the statement " hab angst "

Very impresive numbers. They are just halve I got with the same engines, load and airscrews but with 6S vs 8S. In watt therms there difference is way high.

Thanks for sharing your findings. Were you using the same props for both tests??

Yes, both test with Graupner 14x8.
Next week i will test the 6S with Xoar 15x5 / 15x6.
