Joe Dietrich replied to Brian Buckmaster's discussion Large Voltage Drop After Takeoff
"Actually, a full charge on 4S at 4.1V per cell is 16.4V, total.   Based on your log, Voltage looks about right.  As for voltage drop on take-off, you will have a definite drop once the motors spin-up under load.  (My hex running 3805 motors weighing…"

"Interlock" might be just the feature you are looking for...  unless it too disarms the multirotor like emergency stop."

"Love the Rocket Days!  My wife was really into building and flying rockets.

This is my beast that will climb at 30'/s or 1800'/m.  Imagine the altitude possibilities with a 35 - 40min flight time.  And that's enough time to go up and come down unde…"

"When the Model Rocketry clubs come to the Dry Lake Beds here in Nevada, they get special permission from the FAA to do record height flights with their high power rockets.  That would be a perfect time to hook-up with such a club and go for a legiti…"

Joe Dietrich replied to Virgil's discussion Pixhawk and DJI Spreading Wings S900 Frame Kit in PIXHAWK
"While I can say I put a lot of time, effort and money into my Pixhawk Hexacopter with extended arms and DJI E600 propulsion system, I finally swapped the F/C over to a Naza M V2 due to general reliability issues and the lack of a really good 3-axis…"

Joe Dietrich replied to Pmarche's discussion Pixhawk and some ESCs with Low KV motors. Pixhawk is not the problem. Problem is related to ESCs, Firmware and fine tuning. in PIXHAWK
"I've been running DJI's E600 propulsion system on my Pixhawk hex with pretty good luck until recently (flight crash due to wrong PIDs using a heavier 6S battery than what I usually run on 4S).

DJI's E600 system uses 20A Opto ESCs, 415kV motors, and…"

"What's your all-up-weight before battery?

How does it behave with the Naza M with the 1000 class diameter and low kV motors.  That thing is a beast!  It looks nice!"

Joe Dietrich replied to Ruwan's discussion Share your drone info thread
"The 6S batteries have a lot more energy content than 4S batteries.  Think of it this way, 4S is nominally 15.2V average, and 6S is nominally 22.8V, over a flight run.  Let's suppose you use the same mAh rating for two different batteries, chose 5000…"

"Yep, I run the same SD Card in my GoPro Hero 4 Black.  Seems to do just fine.

Raw video off of the P3 looks really good in my opinion, even at 4K.
As said just about everywhere else, prop balance and proper dampers seem to be the key.  My DYS has w…"

Joe Dietrich replied to Erik Graham's discussion 3 Axis Gimbal for Iris+ - looking for suggestions. in IRIS
"It's possible that when using the front mounted GoPro on the Iris that the balance (CG) was off, contributing to flight instability.  I find that both my Hex (using Pixhawk) and my quad (using Naza V2) fly much better when I use the battery to count…"

I've watched a lot of videos from guys on the RCGroups forum using the Feiyu Tech G4, DYS, and Align G2 3-Axis gimba…"

Joe Dietrich replied to airmazingvideo.com's discussion Pixhawk with BaseCam (AlexMos) SimpleBGC Gimbal
"Instead of using the pitch control (output of an AUX channel on the PIX), simply select an open port on your RX and connect straight to the Alexmos board.

Or you can follow this Wiki:

Joe Dietrich replied to airmazingvideo.com's discussion Pixhawk with BaseCam (AlexMos) SimpleBGC Gimbal
"It should, I have done the same thing.

I just don't like my 3-axis DYS very much (using Alexmos controller).  I just can't seem to get the fine tuning needed to take the vertical (pitch) vibrations out of the gimbal (not prop balance related).  My…"

"What type of TX / RX setup are you running?

With Futaba, there is a certain TX mode you have to select to get 14 channels (transmitting).  And with Futaba, if using S-Bus, it should support up to 18 channels (with an 18 channel TX).  What I have do…"
