After our “crashingly good day” on the Almost Queens Birthday Fly-In the 3Dprinter has been working overtime today.
Started out with a new canopy for Hoppy’s S800 Reptile flying wing (lost during flight)
then a new camera plate for the “almost” indestructible Pan/Tilt gimbal for my Raptor
and then a new engine mount & wing joiner for the Raptor as well
All the minor foam repair work is now completed so just need to repair the battery tray & reassemble it all before fixing the PIFF settings in the iNav Flight Controller.
By the time all this rainy weather goes the Raptor FPV should be ready for another iNav maiden test.
Thanks David, would do the same for a white man !!
Just to let you know your Razor is setup & ready to go along with its very own Buddy Box system.
Just need to make sure you bring the wings & the Prop assembly along if we don’t catch up before we fly again.
PID (the old AutoPilot Control Loop)
P = Proportional
I = Integral
D = Derivative
PIFF ( the NEW iNav AutoPilot Control Loop)
P = Proportional
I = Integral
FF = Feed Forward
Now to understand how it all works Google it in YouTube
Enough to say I forgot to set it up correctly. Oh well lessons learnt by mistakes stay in the brain a little longer.
Seeing as we are now not flying today it will give me time to double check all the alterations to the Raptor before her refit maiden flight.
I’ve spent the last day or so completely redesigning the 3D printed Pan/Tilt gimbal to significantly reduce its size. The original was over 75mm high from the fuselage of the plane to the top of the camera, my new design is closer to 45mm so a significant reduction.
Still uses 2 x 9gm Turnigy servos (TGY-50090M for tilt and a TGY-RS180MG for Pan) and still gives a bit over 180 deg pan cover and 90 deg tilt so the camera can still look straight ahead or straight down over the side of the fuselage.
This was the original design, works fine but wobbles at speed and strips servos on heavy landings
This is the new design which should be a lot more stable
Tried that, NTSC, PAL & Auto.
Anyway its not a problem, the GroundStation DVR screens were always a bit flakey with 16:9 feeds, I think they were designed in the 4:3 days.
The new recorders that BA & I got for the headsets handle 4:3 & 16:9 without any problems.
I’m clear Monday & Tuesday at this stage if weather is OK but I’m NOT available on Wednesday.
All the iNav gear is installed & set up in the Raptor. I’ve programmed the Flight Modes to the 6 buttons on the front of the Jumper T16 and all seems to be working OK. Also used the switchable OSD function on one of the radio’s 3 position switches. Think I’ve now used up around 12 of the 16 radio channels available on the SBus connection.
There are a couple of dozen items that can be displayed on the OSD but it will take a few flights to see what is actually needed.
Here is a test video, it’s a bit dark as it was filmed inside and it’s rather wet and miserable again today so not a lot of light.
The OSD, in conjunction with the Mobius Mini works fine when the signal is received on the HawkEye FPV headset but the bottom of the pic gets cut off when recording on the Ground Station.
The RunCam 2 camera is even worse, doesn’t like the OSD overlay much at all.
If I use the SurveilZone FPV camera this does not happen but then I lose the onboard record facility
I may end up running 2 onboard cameras (as I have on the ASW28), one for FPV and the other just for in air record.
For the time being the Mini Mobius will do just fine.
Just designing & printing a new low profile Pan/Tilt gimbal to hopefully fit much lower onto the plane nose but still be able to tilt over the side and look straight down as well as forward etc.
Something else to keep me occupied till all this crap weather blows over!!
Just been sitting here and reminiscing, checking out some of the old Raptor FPV footage from way back in 2015 down at Calverts Lagoon
and 2017 & Tony’s farm
Thanks Ian, it’s a nice project for a rainy day.
I’ve got most of the programming done and had the video feed & OSD up and running on the bench so now its all slowly being fitted into the “Raptor”
The F411-WSE flight controller is installed along with all its wiring & GPS unit. Just 3D printing an antenna mount for the receiver and once that is done I can finish all the internal wiring in the plane & start fine tuning the FC settings.
I do like the fact that the OSD (sent back to the Ground Station or Flight Goggles) is fully programmable in that you can choose how much or how little info is displayed AND where on the screen it is displayed, all very nice & convenient.
Also I believe multiple OSD screens can be set up with different info and these can be selected in flight via the radio.
I’ll have more of a fiddle with that once all the gear is running in the plane. So far all is working out well and I now have all 16 radio channels available via the SBUS link so won’t need to use two receivers any more to allow for the Flaps & FC control channels. The FC also has a switchable output to allow for two cameras to be connected & switchable in flight. Probably won’t worry about that at this stage but would be a bonus on long flights if one camera should fail.
As I was warned by Uncle G, there is way more programming & stuffing around with the iNav controllers compared to the ones we used to use, they were almost just Plug’n’Play especially when compared to this new stuff but hopefully the advantages will outweigh the disadvantages.
We never had a fail of any of the FY-41AP’s except one (that someone whom shall remain a nameless frog) that got rewired incorrectly and had a hole blown in it. I guess only time will tell.
Oh well, back to work.
Sorry my little amphibious friend but after watching the video I must concur “Bad Boat”.
Duck rules of sailing clearly stipulate that NO BOAT shall go back through the start line or return to the racing side of the start line while the race is in progress.
It really does make the job much harder for the PRO and the scorers.
There are a couple of other skippers that also flaunt this rule on numerous occasions, perhaps they need to be called out in the video’s as well.
Just my thoughts on the matter.
