So I had the chance to take the hotdog out for a proper attempt of endurance and I achieved 25 mins. I am close, not there yet, but close! Here is the flight captured on my new powerplay dvr (this thing is sweet!).
The handing is better, i had to tune it a bit, turn on pid compensation for battery sag, etc. Still needs improvement on video.
Dave, I received the frame. Awesome work mate, thank you! Such a clean job and no curling of the frame at all. The ASA definitely feels stronger against the ABS ones I have printed. I'm giving it a paintjob before I rebuild the dog onto this new frame. Again, great work!

Great flight! Nice smooth proximity flying! Some serious "hot dogging" there It's hard on the fingers flying for this long though isn't it?! I think I need to start doing some more interesting flying like this to help pass the time, instead of just circling at 30m. I wonder if you're getting any ground effect that may be impacting your flight time slightly? No idea if that's a thing actually... just brainstorming.
The DVR looks awesome! Curious what googles and receiver you're using? Also, what camera are you using? I think I saw one photo with a Caddx Kangaroo and an earlier one with a Foxeer? I recently got a TBS Fusion module for my Skyzones, but it doesn't work well with the Caddx Ant.
Also, curious are you using 24 kHz or 48? My latest 3S flight was on 48kHz, but I'm still not sure which is better or if there's even much difference. I'm fairly convinced that on my 1S nano build 24 kHz was superior to 48kHz.
Love this build. I still laugh every time I see the name. Great job.
Heya Amped! Thank you for the feedback mate. Yeah, this endurance flying is killa on the fingers. I'm getting the thumb shakes, lol. I've perfected the move to be able to remove my fingers from the sticks for short periods to give them a stretch, etc...
I think the constant change in altitude would have an effect on flight time. Keeping the quad at a constant altitude for the length of the flight is probably the most efficient?
I'm using HDO2's with rapidfire. Antennas are the True RC singularity series. One omni and one patch. DVR is the powerplay DVR from immersionrc.
The cam is the caddx Kangaroo, it's a bit stuffed though, there's a smudge on the lens internally. Colours are turned up high, good to turn down the stock AGC value for this cam. I'm using stock ESC firmware at the moment, so I Assume it's 24khz? Not sure, I'll check it out though.
I got a chance to take it out for a proper flight, was testing out how it handles with wind,etc. The day for a great day for it. Winds were at around 10-15kph.
I turn back at 1.3Km because of an intersection, I need to go country to give it a proper test.
I've sped this video up, it looks funny when I'm harrassing the cows, they look like frustrated ants, lol..

Sweeeeet!!
Can't wait to see how this material performs in comparison, It's pretty new to me as well but it has been great so far.
As for the curling, that happens with ASA too, and is normally caused by your ambient temp being too low or if you forget to turn off print cooling.

48khz is known as more efficiency as example on whoops, as i know for low throttleauthority builds like 7inch quads or i believe as 4inch with small motors, they get "wobbles" on 48khz. no more efficienceny, less good performance. i believe 24khz is the right choice, but aslong as it cause wobbles, 48khz should be more efficiency.
I painted bffigjam's ASA printed frame red so it will go faster, I have also got a few updates to try on the dog4. Seems that 140x is where it's at. I couldn't get the flywoo motors so I got some iflight ones - 1404 3800kV. I also am upgrading the vtx, vtx antenna and camera.

realy? you scared these cows... oh man
I would agree with this as well. With my last two Li-Ion 3" and 4" builds I've gone back and forth with 24 vs 48 kHz and the flight time difference seems negligible, but the performance difference is noticeable, in favor of 24 kHz, exactly as you said Hugnosed_bat. In fact, with the NanoLongRange, I'm pretty sure the flight time was reduced when I was using 48 kHz.
ph2t, Thanks for the info on the FPV gear you're using. I'm also using the TrueRC antenna's, but Fusion instead of Rapidfire. I think the difference in image quality is your camera and the Powerplay DVR. It looks great!
BTW, I like the new components. What is the Foxeer camera? The Tramp Nano VTX packs a good punch for it's size. That's what I used on the NanoLongRange for 5km and it did well.
i tried explore it a few times. i use higher startup value on my 1s settups. i was focused on motorperformance while my tries. he tells all "weird" quads, not 500g 5icnh build, can probably get benefits by adjustements. im curios what that could mean about efficiency. please share your experiments if anyone start to explore
(might be wrong overall; my actual theory/understanding is lower could be more efficiency, but as motortiming it needs to fit. smaller motors on big blades might probably spin better on a higher startup rampup value. so my guess, as low a s possible would be the route for efficiency but might need an increasement on 2s and 1404 and 4inch. for performance the opposide; as high value as possible, until it turns into heat only or noise. i dont realy understand how kv affect to that xD bluejay esc seems to make it even more complicate by three values for rampup/startup )

Good info and interesting video. I also found a good multipart series on Bardwell's channel that explains every setting in BLHeli_32 (many also apply to BLHeli_S). Seems like motor timing could also potentially have an effect on efficiency. Higher = better performance, lower = better efficiency.
I'm afraid to go too far on any of these settings and risk a desync 5km away, but I don't mind experimenting with some setting for the park endurance flights.

lower the startup/rampup power would decrease the risk for a desync, there wouldnt be a risk by decreasing. uavtech suggest decreasing startup power as a solution for desync issues.
lower motortiming can be a higher risk for a desync. motortiming might be more potential for improved efficinecy. i believe there would be a very low risk for a desync on "medium" (or "16" in blheli 32) but anyway you got goood efficiency on your build: medium might get you to 40min and 30k :-)
to decrease the risk of a desync in general, does lower the performance and shouldnt be less efficiency in anyway, is demag compensation to high. there is a good video from pawel about it.
i believe both values need to match the motor and there will be a small wingspan between efficiency and performance :-) this would need a lot testing

Ya lots of interesting settings to test, but I wish I could find a way to test that doesn't take so much time!
Weather looks good for Monday/Tuesday. I think I'll try 3S at Betaflight default PID'S, motor timing at medium, 48kHz PWM and send it! Also all my park flying has been with the VTX power at 350mW, so I think I'll reduce to 25mW.
Sorry ph2t, I feel like we derailed your thread a hit here!
