This build started out as an extra f/c I was gonna toss in the bin for spare parts. One boring day I was surfing YouTube and came across a video by Tmac where he built a 2.5" tadpole. That little thing was fit in the palm of his hand and zipped around like a 5" bigboy. Insperation sparked and spawned my version of a Armattan Tadpole. What a great little quad.

I started the build by putting motors on and seeing how much wire and room I had. After a few mock up of the electronics I decided to put the XM+ receiver on the bottom under the f/c and stacked the loris dvr on top of f/c and used a whitenoiseFPV 20x20 board for the TBS nano transmitter and mounted it forward of stack on stand-offs. I drilled the holes for standoffs a little off center with worries that the solder joints might touch top carbon plate on frame. Luckly everything fit with a few mm between video trans. and frame. I did use some tape between boards for insurance.

One the mock up was done I broke it all back down and started the full build. first was the wire sleeves for motors. Next I mounted the XM+ receiver and video antenna. Afterwards I installed the f/c and got all wires soldered inplace and left long for installation of other electronics. Here I checked the top plate to make sure it still fit in place and after conferming I continued by installing the Caddx Loris, FPV system, and srewed it all together.

At this point I went into BetaFlight used the setting TMac showed in his video and went flying. A few changes of rates and PID's to fine tune for my flight style. With a custom 2s-500mah battery I'm getting 6-8min flight times and with a custom 2s-1000mah it gets 10-12mins.

By far my favorite drone to fly. The Caddx Loris is a really good dvr, FPV cam is a bit cloudy but with a ND16 and some tuning of cam setting the DVR looks nice.
