Assembly<\/h2>\n
The frame is a\u00a0uni-body with a 4.5mm bottom plate, which should pretty much make it indestructible. The arms end with wide motor pads with plenty of protection for even 22xx size motors. The cage is rather small. The rear end is a bit wider, which gives false hope of room. There isn’t much room, barely enough for the PDB, FC and radio gear. The Cricket VTX ended up sticking out the back a bit.<\/p>\n
There is about 70mm of usable arm space which was just right\u00a0for the rather lengthy XM30A ESCs (with capacitor).\u00a0There will be no\u00a0troubles mounting any other popular ESCs of similar size or smaller.<\/p>\n

<\/a><\/p>\nThere is nothing “mini” about the SPRacing F3 Mini! It is standard 36x36mm size (a bit longer with the LED\u00a0strip in the back) but packed with features:<\/p>\n
- \n
- Direct Lipo voltage<\/li>\n
- Built in 5V 1A regulator<\/li>\n
- Lap time transponder<\/li>\n
- SD card slot for blackbox data<\/li>\n
- 3 UARTs<\/li>\n<\/ul>\n
I ended up\u00a0using the 5V regulator in the FC only, which simplified things a bit – only one cable between PDB and FC. Things were getting pretty crowded\u00a0in the small frame cage, so I had to solder cables directly on the FC, which was a first on a build for me. Still managed to keep things “modular” ensuring that at-least one side of the cable is on a detachable connector.<\/p>\n
Final weight with props and antenna, without battery is 411 grams.<\/p>\n
Update 3\/27<\/strong><\/span>: Flight controller swap. There were annoying gyro spikes in yaw during flight, easy to hear and seem causing the quad to jerk slightly. After some debugging, it turned out to be the Mini flight controller. I swapped with a regular SPRF3. Too bad, because I was starting to like the feature-packed Mini.<\/p>\n

<\/a><\/p>\nYard maiden flight went very well. She felt fast and a bit twitchy on Betaflight 2.5.3.\u00a0Next is tuning and test flights.<\/p>\n

I’ve been cranking out\u00a0a new build\u00a0around\u00a0every month I have been with this hobby. For #6, I decided to do a proper racer with the heavily hyped X frames. Parts List Frame: SpaceOne FPV Formula One 220 X Edition Motors: EMAX… Continue Reading
