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)

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
