I'm finding that I'm re-building all the older analog quad frames I've flown as walksnail digital ones, so I busted out some parts (old and new) to revisit an old frame.

I also wanted to push the envelope a little bit.   1S quads have always fascinated me in the sense that you don't have much power to work with and the margins between performance and a pile of shit are small.

Originally from this thread is a 1S, 3inch toothpick build.  There's some video in that thread, you can see how it performs.  I used the same motors, frame and canopy.  This digital version is currently using gemfan 65mm props instead of 3 inch ones, they're on order.

Highlights on maxing out power.

• GNB 850mAh HV pack, quick large for a 1S toothpick but can handle a serious amount of current draw without voltage sag.
  
• BT2.0 connector using thicker guage (2207 donor motor) wire
  
• 12,000kV 1103 MAMBAS
  
• BL_Heli32 esc with advanced motor timing and variable PWM enabled
  

I used the new current calibration feature in BF configurator and was able to get it quite accurate over a range of loads.  I'm peaking 23A on punchouts, it's mad!!!


It's late here, I'll edit and post more when I should be working, tomorrow.

Very nice, another interesting WS build! It looks like it is flying even better than the 2S build? Are you using a 12A FC?
And those brave big power loops over the roof...

Very nice looking build.

WOW. All my quads are still analog. I would not dare try small gaps like that.
Even huge 1foot by 1foot gaps in tree trunks scare me. I see it really makes flying more adventurous.

That little thing is insane. It sure as hell looks like it flies better than any 1s I’ve seen.

I dig it.

That walksnail video is so good. Very hard for me to fly analog anymore lol. Looks like a sweet build! Nice work!

Thanks guys! mstc I'm using this FC which has bl_heli32 escs.  Yeah I feel it performs better than the 2S one I made too, another reason those fpvcycle 13mm motors just seem to underperform.

Pairing it with these 850mAh GNBs really kicks it up a notch.




The frame is thin and contributes to a fair bit of vibrations.  I think I will convert this over to a TP3 clone frame I have that is way stiffer.  I'm testing out the 3" props this morning and the tune window is bugger all, this frame on 3" props is just too flexy.

I'm using an original 1S vtx where I have removed the heatsink off the main chip.   I removed the JST header for Vcc,GND,RX & TX and soldered direct.   Vtx is hard mounted to the frame.  Toothpick stacks can suffer from gummy overload and that affects noise/gyro/performance.


As I'm doing more and more of now, wire loom pre-setup of AIO, RX, power, filter cap and motors.   Motor wires are too long but I couldn't be arsed fixing that as I've already resoldered the wire leads once before, lol...builder problems...

• TMOTOR F411 AIO 13A version
  
• HM EP2 running 3.5.somthing
  
• 470uF 10V electrolytic, doubt it is low ESR, came with a JHEMCU aio
  
• BT2.0 pigtail with 5inch motor wires instead of stock 22/24AWG wires
  

Easy rear access for USB and the canopy holds the dipole antenna in place.

I've saved the 65mm PIDs into profile 1 and am now trying out the 3inch props.   It is hard to tune it smooth, the motors work more to spin these larger props up but the main issue is the frame wobble.  I will work more on this.  At 50+ grams I thought it would be less power than what I have experienced.  So going to a heavier TP3 clone frame may not be the performance hit I thought it would be.



ph2t.

Very nice. I have an analog pick (3S though) and considered swapping in the WS, but heard that the 1S VTX is relatively fragile and was hesitant. I guess 50g is light enough though (although it looks like your 1S pick flies pretty hard). Is the VTX board corners poking out past the frame? Maybe add some TPU bumper, but probably only more visual/dirt protection than impact protection.

A little, the 1st gen vtx board is huge.   I find that inner edge of a toothpick bit of a no-go zone, doesn't really get damaged.  But alas, I don't fly to close to trees to get hung up on branches.  Too little weight to be able to retrieve easily either.


Here's the best I could get it to perform on 3" props.  The frame is hard wobbly.

That does look shaky, seems it flies nicer on the 65mm. Which 3" props are you using, if HQ then props are most likely out of balance, but Gemfan 3018s are typically fine.

Where did you get that canopy from? I like the format..

Sorry cst3x6, I've looked everywhere, I thought it was from thingyverse or aliexpress but I couldn't find it

I've been trying out the UAVFutures presets for tuning and have had a lot of success.

I used the 2" micro preset and I was able to get the filtering to work well enough that I could use the blackbox data for gyroflow.

The UAV future presets for whoop and 2" - these two presets are pretty nice.  Yes they dull the quad a bit but it handles soo well in corners and freestyle moves.  I found I can really push it into a corner and it seems to hold and not get all twitchy and stuff.

Here's a rip going pretty hard, using mstc's method of lens correction, then cropped a bit.    I like he feeling of speed with this lens correction, reminds me of really large FOV analog cams, 

Nice and smooth, probably better results than the new v2/pro cams. Looks like you got rid of most of the shakes too!

That’s some nice flying and excellent use of a small space.
