"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…"
"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…"
"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…"
"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…"
"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…"
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…"
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…"
