"Buy a Lipo for your R/C transmitter and just charge it with your regular flight Lipos. But watch out! The polarization on a lot of the Lipos that are recommended here are swapped. You will fry your R/C transmitter if you don't fix them first.

"No it's not too bulky. It works perfectly. See here: https://www.cloud-surfer.net/2014/07/11/angled-mini-usb-adapter-for...
Or if you want to take it off for during flights, you can carefully cut the rubber casing off. See here…"

"Yes, they are really that good. That's why I ended up with 4 of them. :-)
Even after quite a few cycles they are still performing great. The plateau voltage stays pretty high and temperatures of the Lipo are very reasonable.
Personally I wouldn't…"

"On your FPV TX you have two cables coming out:
- Cable with red plug. This is for power and goes onto the LC power filter, which in returns connects to the FatShark filtered balance lead.
- Cable with black plug. This is for the video signal. the…"

"That's unfortunately a known issues. Check out this post on how to fix it:

Hope that helps!"

"Can you please enable logging for vibrations and do a test flight again. You barometer-based altitude and GPS based altitude differ a bit at times (See below). This is usually caused by vibrations.

"Behavior of Region of Interest (ROI) differs between Arducopter 3.1 (which IRIS came out with) and Arducopter 3.2 (which IRIS+ is currently using).

"But looking at your throttle curve, I can see that towards the end of the flight you have to give 100% throttle for a long period of time to keep the quad in the air. That doesn't leave room for any maneuvering and most likely was a factor in the…"
"You have to download and provide the so-called Dataflash logs (http://copter.ardupilot.com/wiki/downloading-and-analyzing-data-log...).
The Telemetry logs (tlogs) aren't very helpful in troubleshooting something like that crash. "

"Telem2 is used to display flight data on the display of the R/C transmitter. The FrSky R/C transmitter/receiver in IRIS and IRIS+ comes with it's own Telemetry capabilities. While unused in IRIS, IRIS+ now makes use of that. See here for more: …"
I finally got around documenting my FPV setup for IRIS: http://cloud-surfer.net/2014/09/28/fpv-setup-for-iris-and-iris/No soldering required! I've had 100+ flights with the setup and it works great.For IRIS+ I'll need to make a few changes as IRIS+…
"I wouldn't call that fixed. It's probably just luck.
Before I discovered that the Pixhawk would touch the GPS module I could have a series of a dozen or more flights without issues and all of a sudden a flight where IRIS dropped out of the sky. …"

"Gary, the altitude reported by your Barometer and GPS differ quite a bit. That shouldn't be the case. I can see that the vibrations along the z-axis are very high, which is most likely the cause for the barometer malfunctioning.
It appears that…"

"At a flying field altitude (ASL) of 3,812 metres (12,507 ft) you don't have enough lift with a stock IRIS to fly safely. You actually need close to 100% throttle at that altitude just to keep hovering in the air.
Look at the throttle from your tlog…"
