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.

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)

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
