"Pinky" is a heavy 3 inch freestyle quad.

The main idea behind this build was to achieve small, powerful freestyle quad that could be flown in a yard/park without too much attention. I had a 5 inch before and the only place I could fly it was a plain field, not really close to my house. Flying without any obstacles and alone quickly became really boring - in effect I had one flying session a week and wasn't really happy about it. I think it was the right moment for this build as there are so many RC parts dedicated for micro quads. It seems that whole hobby is going towards lighter/smaller quads and I really can understand it, because this kind of quads gives you freedom to fly almost anywhere you want, without introducing substantial risks.

The frame is Cygnet Pro. I couldn't find it anywhere else than on GepRC page. There are lots of regular cygnet frames, but only the pro version is compatible with larger motors with 12 mm base. I was thinking about using Acrobrat frame for this build, but I couldn't order it without expensive international shipment. I'm really happy with GepRC's frame - it's high quality, and much smaller than Acrobrat. There is less space inside to fit electronics, but there is no temptation to fill this space with unnecessary stuff.

The motors are beautiful pink RCINPower GTS-V2 1506 4300KV. With 3042 props these are enough to send whole quad to space on full throttle ;) Enclosed screws were a little to long and unwittingly I screwed into windings' end that for some reason was just above the screw hole. In effect there was enormous amount of noise during flight. I was adding capacitors, even changed VTX without any improvement. Then I bumped into Oscar Liang's article about shorting motor windings, and I checked screws and ESC for continuity - yep it was that. So just be careful when attaching those little open motors. Another thing are the propellers - those GepRC props are ultra fragile. Once I just scratched the grass and two blades were gone :D I will surely replace them with something more durable.

For the stack I have chosen Mamba Mini MK2. I already had MK1 on my Diatone 239R, and I was pretty happy about it - especially for the price. Nonetheless there were two downsides. First of all ESC is too big - it was impossible to fit ESC and Split Mini boards on the same level. Even with Split moved up it was very tight. Second downside is that receiver is not powered up from the FC when USB is plugged - annoying but I can live with that.

Over the Split Mini there is a finder which I had to split into two pieces to fit there. There are also two things not really visible on the photos. The R-XSR receiver is under Split Mini board - from there it was easier to attach antennas with 90 degrees between them. The VTX is hidden over FC, closer to the rear. TBS Unify Pro can run 800mW, so I installed it hugging with upper frame for heat dissipation.

For the battery I have chosen 3S 800mAh. 4300KV was to high for 4S freestyle - it would bring more power reducing flight time at the same time. Those 3S batteries last for about 4 mins. I actually recently ordered 3S 1000mAh for tests as for me this quad is still too powerful, so I could trade some power for flight time.

The weight of a quad without battery is 196 g. With 3S 800mAh graphene battery it's 273 g. If someone is concerned about 250 g limit there is a room for reducing the weight - no finder, no capacitor, linear antenna, shorter power cables, lighter screws and one battery strap with plastic belt instead of two.

Happy flying!
