The Bastard Kwad

The Bastard Kwad is my first attempt at building a freestyle quadcoptor. I’ve chosen to name it The Bastard because as my first freestyle quad, I’ll no doubt be crashing all the time and breaking a lot of stuff; therefore the thing will not doubt also get called a bastard constantly, so I may as well make it official.

After flying the Mavic Pro, I enjoyed the hell out of flying around in sport mode, so I wanted a cheap freestyle/racing FPV quad to play with instead of risking an expensive quad, flying fast and wrecking it. I had two options, either buy an Eachine Wizard X220S (which has a good rep as a starter quad) or build my own. Consequently I decided to build my own as I think I could do it for similar money to the X220S, pick the parts I wanted, and get experience and knowledge of building quads. At the moment I’m getting the parts I need, and as I order them I’ll list them below along with a link and cost. The Eachine Wizard X220S costs £140.67 at the time I was ordering parts.

Parts Breakdown

I am doing this on a low budget, so most of the parts are coming from Banggood. I know some people frown upon this, but I can’t justify spending 3 times the price on some parts until I’m a proficient pilot.

PartPart bought (link)Why?ThoughtsPrice £
FrameRealacc Martian II 220mm 5″Because its similar to the Wizard, and a copy of the Alien.Nice frame, just wish they would include a brace as well as the stock PDB.£21.04
PropsDalPROP Cyclone 5045 &
HQ Durable PC Props 5043
Good reviews. £13.10 (6 sets of DALs)
£6.10 (2 sets of HQs)
MotorsRacerstar 2306S 2400kV Racing EditionSeemed like the right size and power for freestyle at the right price. £26.07
Under motor LEDsEachine LEDs (red) &
Matek LEDs (blue)
Because I’m a tart! £1.27 (Eachine)
£2.36 (Matek)
ESCsRacerstar MS Series 35A BLHeli_S ESCs – DShot ReadyWas going to get the 30A 4in1 from Racerstar, but it had bad reviews whereas these are highly rated. They are also DShot 600 compatible. £29.48
Power Distribution Board (PDB)Matek HUBOSD8-SEI was stupid and didn’t research my FC enough so didn’t realise there was a version with OSD. This PDB has an OSD plus can more than handle the amps of the ESCs.I’d have probably gone with a different PDB had I ordered the other FC.£12.47
Flight Controller (FC)CC3D REVO F4Was a well rated FC, just wish I’d seen there was a version exactly the same, only with an OSD for an extra £2. I would have got the Omnibus F4 instead.Seems decent so far. A couple of problems flashing, but even a complete newb who’s never done it before (me) got it done.£17.73
ReceiverFrSKY XSRI got the XSR over the FrSKY X4R-SB due to its smaller size and equal range after altering the antenna shielding. That and Banggood had them on sale for £13.50!!I found that it doesn’t matter which X(S/4)R receiver you get as you can upload the firmware you need directly from the Taranis. You just need to make a cable to connect the 2, and flash the receiver to the firmware you need.£13.50
TransmitterFrSKY Taranis X9D PlusIt was a close call between the X9D Plus and the Q X7, but in the end I bought a 2nd hand X9D Plus. £125.00
FPV Camera650 TVL 2.5mm Lens SuperHad II CCD FPV CameraCheap but has good reviews. £17.31
Video Transmitter (VTX)FT48X 5.8Ghz VTX with adjustable powerSeems like a decent VTX, with a band display and the ability to change signal strength. £17.73
FPV AntennaFoxeer 5.8Ghz 3dBi AntennaI’m sure Joshua Bardwell gave this a good rating for a cheap antenna. £6.32
FPV GogglesEachine EV100 FPV GogglesI pre-ordered these without seeing any reviews because they were an absolute bargain! Since ordering, I’ve seen a couple of reviews and the opinions seem to be good, very good if you got them at the pre-order price. They are currently priced at £122.54 with a 54% discount. £70.70

* Does not include receiver, transmitter, batteries, or FPV goggles as they are not included with the Wizard either.

Final Thoughts

Overall the spec is fairly similar to the Wizard 220S; however I have a few components I feel are better, the frame is full carbon and not carbon skins with a fibreglass centre. To me the extra £30 is worth it for the building experience, slightly better parts, and the knowledge that there won’t be any flakey aspects to the build, which the Eachine seems to be plagued with.

I will be releasing a build video at some point; but until then, here’s the maiden flight.
