Fatshark Attitude v3 (should be the same optics dom v2?): min: 27, max: 69, avg: 50ms. Maybe optics is identical to doms, but something is different in processing chain, because averages are clearly higher.
Photo samples if someone is interested (taken with SONY A6300 + Samyang 8mm F2.8, ISO 25600 EV -2.7, but allways at 1/4000 shutter speed, so you know what quality to expect =)
Compared to situation few years ago – now you do not need to use 50g+ motor and 15g+ ESCÂ to get 1kg thrust. Mini quadcopter racing mania made small motors/ESC much better, cheaper and better in terms of thrust/weight. They are high-kV (usually) but for small planes this isn’t bad – you still need speed and not only static thrust.
So, my requirements for motor/esc combo:
Still have enough thrust for unlimited vertical (so at least 800g of thrust)
Have enough pitch speed for penetrating headwind and flying around (so at least 100km/h at WoT)
Efficient setup at low throttle – need ~40km range endurance (total trip, not one-side).
AÅ¡ aiÅ¡ku smarkiai stabdau su Å¡iuo postu, nu bet geriau vÄ—liau nei niekad.
Taip jau gavosi, kad suorganizavome mini-kopteriÅ³ lenktynes:
Ir ties tuom reikalai nesibaigÄ—, bus dar vienos lenktynÄ—s (ir gal dar vienos… Bus matyt)
Na, bet projektas turi savo puslapÄ¯, kam Ä¯domu: http://fpv.team/
Tam kartui – trumpas (dar nepadÄ—tas archyve) filmukas iÅ¡ buvusiÅ³ lenktyniÅ³:
Prisijunkit, dar liko laiko uÅ¾sisakyti Ä¯rangÄ…, uÅ¾siregistruoti ir sudalyvauti =)
I noticed slightly increased latency when flying with my HMD’s, compared to my old cinemizers (plus, not OLED). Not critical, flyable – but noticeable on corners and flying over obstacles at high speed.
Had few screens around, measured latency (just to remind – @25FPS one frame takes 40ms; at 50km/h you fly ~1.4m over 100ms), only few screens provided, i did > 100 photos and averaged:
While 1.2G video is working very well for flying around obstacles, it also has own limitations. 2.4G video is somewhere in middle – small VTX, smaller antennas and good enough penetration, but unsuitable for flying in city (WiFi everywhere) and in meetings (2.4G RC adds a lot of noise even on 2370/2510 channels).
So, i moved back to 5.8G with some of my copters. Did simple RSSI-based diversity, added RX5808 modules to my HMD… Works good enough for everyday flying, but i noticed, that my friend can fly further using FR632 RX. LOS Range is acceptable for both, but he was flying further over obstaclesÂ and in buildings.
Long story short – started with 5.8GHz on mini FPV copter (pocket rocket quad), soon got another, tried 1.2GHz (see earlier videos here) and finally picked 2.4GHz for my video.
Things change with time, Lithuania now has #1 Wi-Fi coverage/speed in the world and now i found that 2.4GHz for video usually has lower range than old 5.8GHz setup. It still works fine in forests or far far away from populated places, but flying in city is next to impossible (for example, Vilnius Old Town, near UÅ¾upio KÅ«drÅ³ parkas – loosing video in 20m away from me, using 2370MHz or 2510MHz which should be away from common Wi-Fi range).
