Revo F4 Flight Controller 20*20mm Built in PDB 5V 1A BEC $20.59
Looks much better than the BG pics. This is the first 20x20mm F4 I got my hands on that runs dRonin (Revolution target). For all intents and purposes this Revo F4 is most comparable with the PIKO-BLX.
I have a set of BS20D 20A Blheli_S 2-in-1 2-4S ESCs to go along with that FC. Looking to build something along the lines of the Piko-X @LitterBug is putting together.
I also spotted this 20x20mm 4-in-1 BLHeli_S 20A ESC selling for only $16.38 -- that's gotta be the cheapest 20A 4-in-1 ESC I've seen regardless of form factor.
yds 20A would be a bit overkill for the tiny 1103/1104 motors... ;-) I'm only running a 10A 4in1.
LitterBug yeah, but unless 20A adds weight or cost, what's the downside?
GearBest just added a PIKO-BLX for $16.21. Paired with their 4-in-1 BLHeli_S 20A ESC, selling for $16.38, makes for a very capable 20x20mm control stack for less than $35
My biggest complaint is how close the components are to the mounting holes, not necessarily the cost or weight. Sometimes smaller can be better too...
F4 FLAME Race Spec STM32F405 Flight Controller Built-in BETAFLIGHT OSD 5V BEC PDB Current Sensor $34.99US Promotion Sale From June 5 to July 5.
Takes the Betaflight OMNIBUSF4 target.. so far every FC made for that target I've tried has worked with dRonin..
EDIT: dRonin Revolution target loaded and configured with no issues.. Looks promising so far..
Brushed FrSky XMF3E Flight Controller, Built-in F3EVO And XM Receiver Module, 29mm X 29mm $25.99
For anyone looking to put together a TinyWhoop, this looks like the best deal I've seen, now that dRonin supports the F3EVO target. EDIT: I have installed dRonin on this FC -- just waiting for the frame to arrive..
Add some FSupersonic 6x15mm 19000KV Brushed Motors (2CW & 2CCW) For Inductrix
This looks like a decent frame to put all them electronics into: Tiny Whoop Model 75mm Aggress Mini CNC
For anyone looking for a PikoBLX alternative to run dRonin, the Micro 20x20mm OmnibusF4 with OSD can be had for about $12 using coupon SFPV.
Just for clarity-- please note that it has a built in character OSD that dRonin drives-- it is not a full-fledged OSD like on Brain/BrainRE1/Seppuku.
Eachine Tiny QX90C 90mm Micro FPV Racing Quadcopter Based On F3 EVO Brushed Flight Controller BNF $29.99
Got mine yesterday, here's an AutoTune.
This is probably the best flying brushed micro to get regardless of price.
Thanks to @Elyot et al. for bringing us the SP Racing F3 Evo target to put on these toys!!
HGLRC F4 FLAME Race Spec STM32F405 Flight Controller w/Built-in OSD 5V BEC PDB Current Sensor $26.99US
Worked out great for me in the Stan200 build -- very easy to work on.
Not dRonin specific, but worth mentioning, the FrSky XSR-M receiver I used in the Stan200 build is also on sale for $14.99US.
DTFc Flight Controller 40% off on the ReadyMadeRC Flat Spin Sale -- price goes down 1% every hour.
... from the description:
Want to try the more advanced dRonin software? That's coming too!
Yeah, DTFcs at $14 a pop, I just stocked up... now 69% off!
Going to be playing more with dRonin on fixed wings with these puppies.
LitterBug Oh man...I really don't need anymore right now...but $14 is tough to pass up!
DTFcs all gone this morning. Still plenty of other good stuff popping up on the flatspin sale.
I waited a few hours and snatched up one of the DTFc's once they hit $15 with shipping. Couldn't pass it up at that price. Not that I have any need for another right now...guess I may have to get some of these random parts laying around back in the air.
Hmmmm. as much as I hate brushed quads, I have a few that could use the Beef's brushed board. @ 5 bucks, couldn't resist. Naze32, so I'll see if it will fire up dRonin.
No luck with Artifice Naze32 on the Beef's brushed FC board. Get's a blink code but never connects to GCS. No worries... old F1 board. I'll just run the stockish firmware.
There's a few BrainFPV Mini Power Board (mPB) left on that ReadyMadeRC Flat Spin Sale right now. Both V1 and V2 for the RE1.
Here's another AIO dRonin capable Flight Controller at an amazing price after applying HGF419 coupon: HGLRC F4 V5Pro ($35.99)
HGLRC F4 V5Pro Manual.pdf
so far every FC I've tried that was documented to work with the BetaFlight OMNIBUSF4 target has also worked with the dRonin Revolution target and dRonin OSD. This one has the VTX built in allowing for an ultra clean build suitable for a low profile freestyle frame with as little as 10mm height clearance.
Holy cow this stuff is getting compact....
