First crash $&*()@#!!!!!!


....first crash with my quad. Flying along great in FPV moving slowly forward (<10mph) at about 15 feet off of the ground when for a split second I could tell the the quad stopped moving forward relative to my stick input and then, bam, I lost my video signal. I got a stomach wrenching single alarm beep from my fatsharks and I knew it was bad. When I found her on the football field she was belly up and expensive electronics were slung everywhere. Unfortunately, no video to review/investigate. My only guess is that I lost main power for some reason. I presume that I had a bad solder connection at some point in the power system. Just glad this didn't happen at 300' over woods, which is exactly where I was about 2 min prior to the crash.

Damage report:

(1) broken DJI arm
(1) punctured lipo
GPS stalk broken (damage to GPS unknown at this point)

Guess I have a reason to pull the trigger on the TBS Discovery frame now.

I had a similar crash recently - had been flying 200 or 300 feet, brought it back (fpv) and was hovering about 10 feet above the ground and lost power. Fortunately, except for a broken camera mount servo, nothing else broke. Turned out to be a bad one piece deans adapter I purchased to tap for the video transmitter. Just a bad plug... wouldn't hold a connection with the battery. Something to say for "hard wired" connections!

I just tried to fly my NAZA Quad. It has been a few weeks sense I have flown. I checked out everything with configuration with the asistant and all looks right but motors wont arm....what could I be missing. LED signals look right....I must be missing something but I dont know what...any ideas?

Do you have dual rates programmed and are you on the low rate. (Not that I've ever done this before )

hexa sudden rolls


I just build a 2-axis gimbal and started flying with it today and was somewhat impressed with how the naza works with gimbal....BUT i started noticing sudden quick rolls to the right and this is scary. Before I flew I made sure to set the remote gains control to "INH" so there's no conflict with the knob that I'm using for gimbal pitch control. This has never happened before without the gimbal. I'll try to fly again tomorrow without the gimbal plugged in to see if this helps. Did anyone here have this problem? I've heard that the Naza is particular about what servos to use for the gimbal, is this true?

I have wondered such watching the TBS video's.
It is important to flood a conductivity pass for amperes.
Wires larger, Solder larger, Connector larger, and especially circuit board TRaces to be larger.
Sorry for your loss.

And they feel REALLY easy to twist/snap - so I was paying a LOT of attention to the wrench holding the mounting plates whilst doing up the NyLoc nuts!

Hi guys, here on vacation and since it's a gloomy day, I thought I'd take some time and install/program the GPS on my quad. I am having two problems that I can't quite figure out... did some reading and I'm still baffled. Wanted to turn to the forums to see if you guys could assist.

1. I have a Futaba 10CHG. Basically the same as the 10CAG, but a few switches are moved around and it defaults to heli programming as opposed to airplane programming. The Flamewheel is set to acro (airplane). I have the Control Mode Switch assigned to a 3-position switch in the radio. It correctly moves from GPS/Attitude/Manual when toggled. I created a gear/gear mix - assigned to a 2-position switch - that correctly moves the slider to failsafe except when the 3-position switch is in the center (Attitude). That may be a limitation of the radio but was wondering if there was a way around that.

2. In the failsafe menu of the radio, the only channel that is available for adjustment is the throttle channel. Apparently that's a limitiation if using a 7-channel receiver. Makes no sense to me. Anyway, I set the throttle to 50% and when I power off the transmitter, the throttle correctly moves to 50% in the Naza setup software. However, the slider never moves to failsafe. Is that again a limitation of the radio, which is why the Naza doesn't go, "Oh okay, you've lost link, let me go into failsafe"? Or am I missing something?

Thanks again for the replies!

you need to be able to program the failsafe in the RX not the TX

after its lost the signal from the TX its the RX that moves the channels to the presets.
The naza recognizes these presets and engages failsafe

Also

Try setting up your TX in Heli mode using single servo swash and you can use the Pitch channel and flight modes switch to control the Manual Atti and GPS modes and then you can use the Throttle hold position to manually switch in and out of failsafe.

Works a treat on my DX8
