Bernie Hoffman commented on Bernie Hoffman's blog post New Heavy Lift Prototype from Autonomous Avionics
"Thanks for the comments so far! Not shown in the prototype is the anti-vibration mount. We are working on a better mount to isolate the aircraft from the gimbal.   Heat is always an issue and we are looking to add a cooling fan to the main…"

Duran - SteadiDrone commented on Bernie Hoffman's blog post New Heavy Lift Prototype from Autonomous Avionics
"Interesting, the trick is to go with bigger props, lower Kv and higher voltage, check out the SteadiDrone VADER for ideas, the HL version does up to 55 pounds payload, and the standard version, up to 50min flight times."

"Those ESC's will get hot, here in Australia it's coming to summer. Without airflow and lifting a payload it's going to heat up :-) "

"How are you guys handle vibration to the payload? looks like the toad in the hole is just hard mounted to the bottom of the frame?"

"Hi DougB- The aircraft will handle a 20 knot wind pretty easily and is rock solid in the air. I will work on getting some video from the camera and of the UAV flying shortly and will post it when available.   I do have a short clip from the…"

"Do you have any video of it in flight? Also, some video from the camera in flight? How stable is it? How much wind will it handle? It looks nice,"

New Heavy Lift Prototype from Autonomous Avionics

Looking for feedback on the Autonomous Avionics SkyTractor Heavy Lift Octocopter. Any input is appreciated. Practical payload is 20 pounds, but we tested it with 30 pounds. Flight time is right around 12 minutes with the full payload, but the RED and Movi only weigh in around 12.5 pounds, so flight time should be…See More

"Hi, I'm the proud owner of a cortex with pixhawk, and i had a lot of fun to work with it. I have a problem now that i need to put larger props ( i was flying soft 15", and i want to put tmotor 15 on the top and 16 on the bottom, as…"

CarbonCore Cortex by Autonomous Avionics

 Autonomous Avionics is proud to annouce their latest ready-to-fly X8 octocopter. The CarbonCore Cortex folding airframe is an 800mm coaxial carbon fiber airframe loaded with a 3D Robotics Pixhawk flight controller. The 8 MN4120 T-Motors are more than adequate for carrying a full frame DSLR camera and 3-Axis gimbal. Each…See More

Bernie Hoffman commented on Bernie Hoffman's blog post Latest Build - Carbon Core 950
"I love it! Great flying airframe and have happy with the results so far. I have recently upgraded to the Pixhawk and it is amazing. I have mounted a gimbal and a set of larger landing gear since I posted these photos and I currently fly a Sony NEX 5…"

Oliver Volkmann commented on Bernie Hoffman's blog post Latest Build - Carbon Core 950
"Hi Bernie, How's your quad flying? I've got a similar setup using the same motors but flying 2x 6s packs. Today I flew without payload and got 29 minutes of flying... Just curious to hear what you think of the Quad frame you have and how…"

"I like what you are doing, there is not a fully loaded Arducopter PDB type of board anywhere bar hacking your own, Good work!"

Bernie Hoffman commented on Bernie Hoffman's blog post Power Distribution Board
"I fly the APM 2.6 and use 6s batteries. That was certainly a factor in designing this. I also believe something the flies shouldn't have parts that dangle. I solder all the connectors I can after experiencing a mid-flight mechanical due to a…"

"Re: Current sensor - the new immersionrc version for the ezOSD now supports 6S. I found it to be a more elegant waz of Current Sensing, as I was going to use immersionrc for the FPV kit anyway. I also have the spektrum current sensor (easy to run…"

Power Distribution Board

Posted on October 15, 2013 at 3:52pm 7 Comments

After putting together a Carbon Core 950 and trying to fit all the electronics, ECSs and miscellaneous electronics into the frame, I realized I really need to use a power distribution board to keep the installation clean. I know there are some pretty good power distribution boards available, but…
