Gunter, no, that is not an good idea. Acrylic is Polymethylmethacrylat or Acrylglas. This is hard and strong, but will break. Other domes are made of Lexan (Polycarbonate) and this is elastic, strong and will not break. Dirk

No, there is a firmware upgrade for the RMK 2. I think it is version 2.01. With this firmware 12 channels and failsafe is possible. I am using it and it is working fine. Link: http://mikrokopter.de/ucwiki/en/JetiReceiver Dirk

Some pictures and the high end gold plug. Gold Plug: 6mm very high quality Plug-System. The connectors are insensitive to the fire sparks arising by connecting the Power-system with the battery. The lamellars are inside of the jack, so that even frequent using will not affect the...

I am using two LiPo batteries 5S 5000 mAh 40 C parallel. So the batteries can deliver 2x160 ampere without any problem. Also the full throttle is only needed for 2 or 5 seconds, when you want to climb or rise very fast or when you have horizontal full speed and want to brake very fast. Standard...

Hi Wayne, I am the owner of the maiden flight video. Believe me, the props are APC 15x4. Sorry ,I am sitting in a car, but will give you some more details later. Dirk

Maiden flight done: http://vimeo.com/28371418 The MK Bl-Ctrl can handle up to 40 ampere. With an 5S LiPo 800 watts are possible. With 8 motors you will have 6.4 KW. I am using APC 15x4 propellers and the thrust is 3,2 kg per motor. I will do a test with 5 kg payload in the Next days and will...

I'm using two LiPos 5000mAh 5S 40C. One LiPo for 4 ESCs. There are two cables (plus and minus) for the first bank (4 ESCs) and two cables for the second bank. By a maximum of 40 A for evry BL-Ctrl the maximum current is 160 A for one bank. There are high current connectors available for this.

APC 15x4 and 5S LiPo

Yes. There are some other problems. When the camera is parallel to the ground ( 0 degree) the cc board works. But when the camera is tilted down (30 or 40 degree), the cc board has problems and the stabilisation is Bad.

I tried the CC board with different settings several times. The tilt axis works fine, but the roll axis isn't usable. Why? I think, they are similar. With smooth settings it will not work, with stronger settings it starts to swing by itself and will not stop. I have changed every possible...

I think he can do it ... you have to pay only 5.000,- € for the development costs ;-)

Yes, I am using the MK BL-Ctrl 2.0 with heat sinks. With 5S LiPos and 35 ampere a thrust of 3 kg is possible. Dirk
