CS8 to X8 conversion - Herkules ESC III V3

[BorisS]

weight with the cables which are to long and will be shortened is 104 grams which i not bad considering that they are able to do beyond 40a ......... FW on and cooling maybe 100A?

weight without the cables and a simple molex connection on one of them with the bullet connectors on is 34 grams.

compare this to 8 lets say plush turnigy 40A (max 55 burst) with short power cables 28 grams x 8 = 224 grams and eventually you will need some power distribution.

Anybody any concerns with the placement of the components like this ? IMU Lipo over it is a problem ? Herkules ESCs close to IMU ? Remember compass is in the GPS module.

Techically i see no problems. Just dont go to close to motors, becaue magnets form motor are 20-50x stronger then mag. field from lipos.

 

[BorisS]

yeah lets see maybe i will do some construction and mount the GPS over the lipo. Everything arrived today except the boom clamps for the landing gear, so i mounted it provisionally.
Its a very fast build maybe 2 hours. Carbon seems of very good quality and maybe i got lucky but for once a KIT were the producer is not stingy about the screws i got more than actually needed unbelievable

For now i am really happy with this frame !!!

Hi Boris i will send u tomorrow missing boom clamps.
U will see how this baby fly.

Thanks again.

 

[Emowillcox]

Boris nice looking build. Are those motor mounts something that can be bought or they are part of a kit?

 

[krleas]

Both, they are part of kit and u can buy them as spare parts.

 

[Emowillcox]

HI Krleas... thanks for the info. Can you recommend a good place for getting that type of mount?

 

[BorisS]

Thanks Krleas, but I will need two to three weeks to get it up and flying anyways since i will cnc a special alu plate for cooling the Herkules II. So if think you get spares in the meantime i am fine with waiting. But if you are not using the landing gear since you have the 360 on it anyways i would also be happy if you send them so me !

Thanks

HI Krleas... thanks for the info. Can you recommend a good place for getting that type of mount?

We will have them in shop after 25.10.2011

[Emowillcox]

what section will you have them under on the web site?

 

[krleas]

Cinestar, spare parts will be added in few days.

 

[BorisS]

@ EMO, pretty sure here http://www.kopterworx.com/Spares-Cinemastar/View-all-products

My whole kit is from Krleas ! Thanks once more for the fast servie Mister M.

Gonna change the Herkules setup and include a cooling plate. Hope to still get the Coolingplate sample today out of acrylic just to check if everything fits. Probably will change the mounts of the plate though from the standard holes to outside holes with little arms coming from the cooling fins. Think that should protect the Herkules II better in case of a crash.

Finally have a acrylic prototype of the cooler, still needs some tweaking but it seems to come along. Thanks !!! to Gunter I have a 3D version now of the cooler which will make it easier to adjust to what i actually need.
Think though that 5mm will be to thick for the cooler lets see ! Pretty fixed on the placement of the other components not. Like the way WKM in combo with the Hekules II how much space one has left on the center plates.
Dont even want to go that road but one could redesigned the frame/center plate reducing weight etc.

Hmm will have to mount the Lipo bridge higher. Thats for sure and will have to add a roll cage for the Herkules II. If this Lipo construction brakes the lipo impact the Herkules first and i dont want that.

[Borneoben]

Awesome

Looks great Borris

Its great to see someone putting as much effort as you into getting things set up just right.
I dont know many other people who would bother getting an acrylic prototype part machined to make sure its all correct.

I used to do that with my Helicopter frames i used to sell to save on the carbon fibre!!
The number of people who asked me for Acrylic kits was unreal they really thought it was a great idea and wanted to fly it!

BTW its normally called a Heat Sink as opposed to cooler but we know what you mean!!

Keep up the great work.

I hope you dont mind me asking but what is your day job?
You have some serious money tied up in this hobby!!

[BorisS]

Oh yeah heat sink should have known.

Ben, I am actually a real-estate developer and i was lucky to sell most of my stuff in the last years. Given the unsure times of how which market will react in the coming years i am relaxing a little bit in starting new projects. Different to the USA or some countries in Europe the realestate prices in Austria Vienna actually increased since the start of the financial or depth crisis what ever you want to call it. So i don't trust the hype. Originally the whole multi-rotor thing and starting with a MK AD 8 came up to film real estate and differ from the usual presentation developers use here in austria. Now it became a hobby or even a little to much, my friends think i am crazy

I think the acrylic prototyping makes sense the cost are really minimal and i have a shop 5 min car ride away from me. And its not so expensive. Costs of the parts today was 20 Euros cutting and material. Just makes sense before I bring the heat sink to a 2 axis 3 axis cnc guy and than that means cash or even more cash if something is not working out.

I am also in the lucky state to buy stuff over my company so tax dosent play a role and than i might be able to write off the costs as marketing expenses towards my profit, lets see what the reaction will be

Thanks for encouraging me its really fun to do this stuff. Finally some hands on for me. My work team always get nervous when i lay hands on something on the construction site

Boris,

I loved the build, especially the IMU and MC parts!!

I think the placement of IMU is somehow important for W-M configuration. I have set the distances from the center in W-M tool but I still have unwanted yaw movement.

I look forward your videos, how it flies..

 

[BorisS]

Japp especially the IMU and MC parts are very very important, and even more the Letters on it, so i can distinguish which is which,

Just three quick things concerning your yaw issue.

1. Compass in the GPS modul, Gps modul mounted on the rod results in a negative number in the config tool ?

2. Sure the little red arrow of the gps module is face forward ?

3. I bet you did already play around with the basic gain settings for Yaw, 100% default setting shouldnt allow this behavior.

Boris

Once more thanks Gunter !!!
