Building an X racer
#1
I’ve been cranking out a new build around every 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 2205 2600KV
  • ESC: DYS XM 30A – BlHeli, Oneshot 125 + Damped Light
  • Flight Controller: SP Racing F3 Mini running BetaFlight 2.5.3
  • PDB: Birdseye Mini PDB, without step-down, using only the FC regulator
  • Radio: FrSky X4R-SB (sbus)
  • VTX: Cricket 600mW
  • Camera: Pyro Drone 1/3 Sony Super HAD II CCD 650 tvl IR sensitive with 2.1mm lens
Assembly
The frame is a uni-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 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 ended up sticking out the back a bit.

There is about 70mm of usable arm space which was just right for the rather lengthy XM30A ESCs (with capacitor). There will be no troubles mounting any other popular ESCs of similar size or smaller.

  

There is nothing mini about the SPRacing F3 Mini! It is standard 36x36mm size (a bit longer with the LED strip in the back) but packed with features:
  • Direct Lipo voltage
  • Built in 5V 1A regulator
  • Lap time transponder
  • SD card slot for blackbox data
  • 3 UARTs
I ended up using the 5V regulator in the FC only, which simplified things a bit – only one cable between PDB and FC. Things were getting pretty busy in 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.
Final weight with props and antenna, without battery is 411 grams.

Yard maiden flight went very well. She felt fast and a bit twitchy on Betaflight 2.5.3. Next is tuning and test flights.

Wow, That's a really nice quad Smile
I like that frame, really simple and short body close to a real x layout...

is that HQ 5030 prop? try some 5040 man, even Gemfan 5045 works super well i tested last weekend hehe!

Thanks Oscar!

Yeah HQ5030, good eye. I had a few pairs laying around. Decided to try something a bit calmer first and hope to work by way up to 5045 tri-blades.

Cool Smile
when i was running gemfan 5030, it was drawing 12-14A of current at 100% throttle during flight on mine (kiss setup), no where near the stats i got from static thrust test hehe... where it was drawing around 20A... that's why i deciede to run some higher pitch props to make the most out of my ESC hehe
