Hm, confused about flight duration. First and second safety limits in Naza software are 23.10 and 22.20 (3.85 and 3.70 V/cell correspondigly). I have 2x6Ah 6s batteries. Attached 1.5 kg weight (total 6.5 kg vs 5.64 kg thrust at 50% and 7.8 kg at 65% according to specs) and performed test...

Assembled, without gimbal. Weight 5.0 kg. I'm going to order Arris 3D gimbal, so total weight will be 6.5 kg, while thrust at 50% should be 5.65. I hope, it is still possible to get reasonable flight time with it. Maiden flight

Tarot CW and CCW adapters appeared to have too long threadless part, so couldn't tighten props. Need to find some properly sized washers http://www.rctigermotor.com/html/2013/adapter_0916/73.html Therefore, used adapters supplied with props. Nevertheless, it would be nice to use the above...

Electronics were mounted on a 2mm thick A5 (15x21 cm) carbon plate. Carbon plate was attached by 4 M3 x 60 mm bolts (rather rare thing to find, had to order it from UK) into holes leading through mounting brackets. Plus two bolts and nuts on sides, through some free holes. 2x1cm nylon spacers...

Power distribution system. I was following an advice to keep it as modular as possible. Wiring is made of 4mm2 (approx 11 AWG) cables. Next time I'll use silicon coated wires, they are more flexible. Tarot power distribution hub was used...

Landing gear mounting. Tarot retractable gear TL96030 was selected due to necessity to remove it from the field of view of camera during video panning. http://www.tarot-rc.com/index.php?main_page=product_info&products_id=1263 Probably, the most ugly piece of equipment in this drone. Mounting...

Ok, so it should give some sound together with blinking. Let's assume that I'm too paranoidal. Should it be precisely in the center? Manual says "close to center". Do a few cm matter?

Well, it should be possible to hear at max volume. It could be normal beeping if it would be "cleaner" so and, like the one from ESC. But I've never heard such "noisy" beeping from electronic devices

Here is a video with sound. Sound pattern follows the LED blinking, I wonder if it is just a strange type of "beeping"

Well, finally got all parts replaced or re-odered. Mounted all electronics on the additional carbon fiber plate. Upon powering the system, led flashes as it should, but also strange hissing sound coming apparently from Naza module appears. Is it normal?

Update. Received motors today and carefully tested them on a separate power board using digital IR thermometer. No issues were detected, both work fine. Probably, I had some wiring issues earlier. Paypal dispute is closed and apologizes sent to the seller. I'm feeling a bit ashamed for such...

http://www.mhm-modellbau.de/ I would like to share my sad (and unfinished yet) experience with the above mentioned seller. Sorry for the long text, just want to sort everything in details. 13.03.2015 I made an 1000+ euro order from this shop (parts for T810: MN-4010 370 kv T-motors, ESC's...

Failed Tx and motors were sent back to seller. While waiting for replacement, I was playing around with charger. In the beginning I bought iMax B6 50W. Well, that's was a wrong choice. It went crazy after the only one charging of 6 Ah 6s battery, so I sent it back and acquired nice, colorful...

Joe Copter Pilot I've ordered an A5 (15x21 cm) piece of 2 mm carbon fiber and a handful of long M3 x 50mm bolts. Going to mount it under, using 12 bolts holding unfoldable arms. Set of 2 centerplates (like AzViper uses) would be great, but it is a pain to order anything to Europe from...

AzViper I've changed the whole idea. I decided to go towards fully operational video system also. Therefore, I'm planning to use secons Tx for gimbal/camera. I guess, 4 ch should be enough. Trigger, pitch, yaw, roll (despite i'm not sure if anybody would need adjust roll manually) P.S. What...

Old Man and Joe Copter Pilot, thanks for comments Yes, it seems that I need an extra layer to mount gimbal and retractable (I got motor-powered one) landing gear. It is a bit strange, that only 2 plates set is available for T810, and it costs 70+ dollars. Actually I was thinking to buy 2 mm...

Hm, regarding the motor fail. Stupid, but I've realized that carbon frame is somewhat conductive, at least between some spots. Could failure be caused by some voltage on the motor mount base?

It seems that I'm starting to run into troubles right from the start. 1. Performed ESCs calibration today. 5 motors were ok, but one didn't start in the beginning, just performed a bit of jerky movements for a few seconds, then spark occurred inside of the motor and it started to rotate. But it...

Apparently, both 8th channel and power supply go to the same slot, found this Y-harness in the box After reading of different topics at different forums I got an impression that length of ECS to battery wires seem to be a kind of religious question, similar to wires discussion in Hi-End audio...

Hm.. I don't quite understand how to deal with receiver power supply. I have Futaba R2008SB with 8 channels. According to manual, power supply by servo cable goes into channel 8. But in this case, I have only 7 channels left and it is not an 8 chanels receiver anymore. Am I missing something?
