Whirlygig 2" Version 2
By 1Smug_Bastard on Jul 26, 2019
Continued evolution of the Whirlygig frame.
Weight (as shown) : 62 Grams with Props, Camera and Batteries. Could lose maybe 2-4 grams from it if i used shorter receiver antennas and trimmed the wiring a bit more.

9-3-2019: First flight outside after retuning PID's.
9-1-2019: After return from vacation in the Dominican Republic, I've managed to tune this little beast to fly much smoother. Pastebin of the CLI-DUMP: https://pastebin.com/VLCdT7Z7
8-1-2019: figured out why the BetaFPV FC wasn't working and made a quick video of the first flight since the rebuild. Obviously this still needs allot of tuning work but hey, i did the rebuild in just a few hours time. Gota fly out to Houston tomorrow so I'm glad this worked out. Especially considering that i realized after the flight, that the PID loop was set to .4 Hz ! (reset it to 4 & 4 Hz with D-Shot 600)

After i get back from Houston, i plan on fully tuning this Tri for my son. (Dont have my gear with me currently)
Should everything go well, I may create a 2S bicopter version that uses 3" props. The ducts will be altered to act as Ductwings. Thus allowing the duct to provide lift from only one side as the copter is in forward flight. (front facing edge will have an aero-lip, while the rest will not) This will allow better stability in forward flight as well as provide additional lift. Only issue I am having thus far is finding 3", two bladed, stubnosed props. Those would be the most efficient while keeping the duct clearances as tight as possible. Could use 3 bladed props but the flight time and current draw wouldnt be quite as good.
Side note: I've picked up some Fatshark HDO's / Rapidfire while here saving me 300-400 with respect to EU prices. Should have onboard recording if i remember correctly.
WE NEED FLIGHT VIDEOS!! dudee thats still makes me widen my eyes because its soo cool!!!
Yeah for the moment at least, i am having a bad run of luck with the gear. To be honnest, the Tinywhoop FC's have been disapointing, both in their avalibility and in their reliability.
Here i was hoping to run this in Houston and have my brother record for me. Would of flown it in the Dominican Republic too as that is our next stop, Guess there is too much going of this week and it just figures that i cant have my cake and eat it too.
Hey dude, so you kinda inspired me and i kind ahave some spare parts from my 3". I also modified the broken frame to only have 2 front arms and ill make somekind of servo holder and motor mount for the back. Got any tips for anything software and hardware related?
Guides & Reviews
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..
