GPS Racer: worklog #4
Yesterday I finally maidened my GPS Racer in full FPV configuration. RunCam Owl Plus and VTX finally arrived, it was not raining, so I took recording gear after sunset and went flying. To be precise, it was not “night”. But it was pretty dark. Too dark for my RunCam Swift. Owl Plus was sensitive enough…

Hands on: Scarab Knife 200
This pile of parts you see below will turn into an FPV mini quad next week. To be precise, it will turn into Scarab Knife 200 by CarbonBird.com. It’s late and I’m overwhelmed with the number of parts in the package, so I did not even attempted to unpack everything… Bottom line is: this looks…

Soldering for beginners: ESC, PDB and all those cables…
As some of you might have noticed, I’ve started to publish videos on YouTube from time to time. I was rather not advertising them here. This will change and you might expect a series of overdued posts with some of my videos. Today something hardware related: soldering for beginners using ESC, PDB and power cables…

GPS Racer: worklog #3
GPS Racer project is almost done. Last week I’ve assembled al the electronics I had and maidened it over the weekend with partial success. Build is still missing FPV gear: RunCam Owl and VTX did not yet arrived so. Without them, final specification is:

SmartPort inverter for F4 flight controllers
While STM32F4 family processors installed in newest flight controllers are superior to STM32F3 (and F1 of course) in terms of raw speed, they are inferior to F3 family in terms of IO handling capabilities. For example, F4 family is not equipped with UART port inverters. There is an S.BUS inverter, but not a SmartPort inverter.…

Hobbyking Mini DLG Pro 990mm durability fix
Entry level DLG (Discus Launch Glider) from HobbyKing has a quite important flaw for a “entry” level model: it is not durable. As a matter of fact, it is quite fragile, specially where plastic nose section is attached to composite fuselage tube. It is attached only with 3 small screws, and I can guarantee: every…
