This is my second build of the Armattan Tadpole frame with pretty much the same components with the exception of using an r-xsr receiver and adding a 9x4mm micro buzzer. The buzzer dimensions listed on emaxmodel's website state a height of 5.5mm but the ones i received were 4.0mm height. I never took any pictures while building like in my previous build as theres not much of a difference. I just took some close ups to illustrate the room available for the camera connector and buzzer. Last pic is both builds together; First build on the left.

If you are interested in my First Armattan Tadpole Build log, please see here:


As previously while building i tested the motors and while spinning them up to test motor direction i found 2 of them to be excessively noisy, the other 2 sounded fine but did not sound the same as each other. Motor 2 (On ESC2) i find to sound like what i would expect from a new motor out of the packaging. I have ordered a total of 10x of these F1103, from the first batch of 5x from europe 1x was excessively noisy and oddly or infuriatingly 2x from the 2nd batch of 5 from T-Motor directly i found to be excessively noisy.

This time instead of snipping the runcam nano 2's connector, i left it attached and soldered a corresponding connector to the flight controller, which there was actually enough room to do which i didn't do in my first build.

Also even though its the same Mamba stack i ordered the ESC has different style solder points than the previous, the previous had a little notch to accommodate a thin wire but the later one i received has a very open arc.

Motor Test: (My first build can be seen here on the left with some HQ65mm props)

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
