FlyfishRC Volador VX3 3"
8.14.23
------------------------------------
Update 8.31.23
I went to install the included go pro mount and it is designed for the regular gopro mount, not the bones 10. i cut out the middle tab and put in spacers, seems solid.


------------------------------------
This build is for smooth flying while filming with a Bones 10. No flips, rolls, etc, hence the tame rates. I am very impressed at how smooth it flies and pretty much vibration free as you can see from the osd footage in the video. I do have sorbothane under the Bones.

Instead of mini Immortal T(which was going down to LQ 1:85} i switched to the L zip tie configuration and now the LQ barely dropped below LQ 1:100 going out 4,000'


The video was filmed at 10,000' and tested with 3 & 4s batteries. The 3s were very lethargic with no real power but flew well. The 650mah 4s is perfect lots of power and flight time with bones @ 4 minutes. For 3s throttle mid is at 53

This flies so good that my Impulse Alien 3" is now shelved.

TinyHawk II FreeStyle TinySleds Install with TBS Nano/Unify Pro


This is for a install of the TBS Nano Rx and TBS unify Pro32 VTX into a TinyHawk II FreeStyle using the TinySleds. There directions are found here https://tinysleds.com/products/emax-...le-vtx-rx-sled

The directions on the TinySleds website leave a lot to be desired and they show photos of the V1 sled so the pin out is different. The soldering is difficult on 2 sets of pins, 4 pins from the FC that come up into the Tinysled, and can be easily bridged. Make sure you have the smallest pointed tip possible and use good soldering practices.

You need to remove the VTX and this can be done by either clipping the pins (4) or heating the pins and prying off the VTX, this is what I did and it was easy. Have seen videos and cutting the pins off just under the VTX also looks easy.

There should be 2 spacers on the 4 pins, remove one spacer so there this just one on each pin, this will ensure the sled is down far enough so the top plate can go on. Make sure to plan ahead to make sure the top plate can go on.

Unsolder the RX antenna
Now is a good time to move the capacitor that was tucked under the old VTX out straight onto the arm so it is not so cluttered above the FC
Solder Nano VTX onto TinySled Board

after not flying for over 2 years due to sickness i am trying to get back into fpv. before i was sick i was flying 5" quads and going out miles and getting beautiful footage. sold those off and will be trying the emax tinyhawk freestyle 2 as my hands and coordination are not good.

this is the analog version as that is all i know and i had the complete ground station and taranis x9d+. this is very easy to fly and is amazing for how small it is. i got the caddx peanut and after a small test flight it seems to handle it quite well and the footage looks good. if you are wondering what all the green tape is for, it is so i can find it in the grass if i crash, makes it much easier to find.

How to tune PID´s on your miniquad in 10 steps! (9 min 6 sec)

PID tuning

p roll- sweeping turn
dips in corners – increase
oscillates – decrease

p pitch -
flies like on a bumpy road – increase
oscillates - decrease

TPA – do a punch out
oscillates – increase
a normal value may be .2 to .4

I roll - punch out and see if it stays level
if it drifts - increase
if it feels like you are flying through thick air or that you have to force it – decrease

I pitch - fly straight, flick the throttle
if loose and driftey – increase
stiff or robotic – decrease

anti gravity - locked in for quick changes
try 3 to 5

D roll - fly and snap half rolls
if bounce – increase
if stops but oscillates – decrease

D pitch – helps with prop wash, do quick half flip
if bounces – to low
oscillates – to high

go up and then straight down flat in prop wash
wobbly – increase D on pitch and roll
CAREFUL can make motors hot, small increases

YAW - do pirouettes and stop, LOS
if it shakes P to high
if it doesn't stay level increase P

Setpoint Weight
Freestyle – LOW might be around .6 smooth but loose
Race – high gives locked and robotic feel

been trying to get rid of the last vibrations found in my 220 size quad, they are not bad but are noticeable on punchouts and higher throttle
--------------------------------------------------
update ; 3/4/19
giving up on the joshua bardwell f4 fc, it just has to much noise which is causing vibrations. i think it has to do with it being a aio and the vibes are being transmitted up the esc wires to the fc. see blackbox log below, SO much noise.

test 1
martian 220
bf4
bardwell f4
brand new tmotor f3 2400
different props, dal bull nose, cyclone and dal 5045
racestar 30a esc

first updated fc to bf 4 and tuned all filters per these
https://www.rcgroups.com/forums/show...-filter-tuning

better but still not perfect. fc stack is mounted on M3 female to male threaded rubber vibration dampening bobbins per many videos. fc is on bottom, akk vtx is on top.

next step was to hard mount fc so i replaced the bobbins with bolts, the barwell f4 still has dampeners in the mounting holes. akk vtx is mounted on top with nuts separating the fc and vtx, this worked a bit better but still vibes on punchout, cyclone props were the quietest

final test, took off vtx that was mounted above fc on stack, put foam under fc and it seems much better! since there is no other palce for the akk board vtx i will have to live with this
------------------------------------------------

test 2
x220 frame
bf 3.5 stock pids and filters
brain radix
gs 30a esc's pwm set to 32khz
brother hobby 2450kv brand new
dal props new, not balanced or polished

mounted the stack like seen in photo, pdb on bottom, brain radix (has dampers built in) on top, long screws with dampeners in between, foam in between boards and on top. did a quick flight and it was totally vibe and jello free. amazing! i think the pdb on bottom and nothing on top of the fc helps a lot along with using screws.

crossfire setup
https://oscarliang.com/crossfire-betaflight/

In the Taranis, long press the Menu button, then press page till you get to the “Hardware” page.
On the Hardware page, there will be an option for “Max bauds”.
Change the Baudrate from 40000 to 115200. This will slow down the communication between the Taranis and the module, but it’ll fix the issue.

Another TBS Crossfire Mini RQly and RFMD chart from flight on 5/8/18

What is interesting is that flight one was farther, about 1.6 mile, but shows less signal loss.
Again RQly and RFMD are the important numbers here. RQLY got down to 76 while RFMD never dropped below 1, this is good.
This article explains it all
https://oscarliang.com/lq-rssi-tbs-crossfire/

this is from 4 flights and shows Rqly, Rfmd, Rssi, and TMWR which i think is transmit power?
Flights 1 and 2 are only about 3,500' in distance but are 2,000' up in elevation, a mountain flight so i was never more than 400' AGL.
Flight 3 is pretty much straight out and about 1.2 mile out.
From what i have read if RQLY is below 80% when RFMD is 1 or 0 it is time to turn back. RFMD reads as 2 on the top and then 1 on the lower and it never goes to zero.
RFMD = 2 , 150Hz Mode, fast updating
RFMD = 1, 50Hz Mode, long range
If RFMD = 0, 4Hz Mode (no telemetry)

still had great video and you see the readouts from the crossfire in the chart. battery is only limiting factor
