This build is intended for mid/long range fpv flights. Next to an efficient power train setup a GPS module and long range radio link setup are on my wishlist. might even try https://github.com/iNavFlight but step by step – this is the initial build and i’m still struggling to ghet the HGLRC Ublox GPS Module working correctly.
Video is from the maiden flight – so don’t expect anything outstanding. The second flight with the big bang i forgot to press record :/
Finally i got the GPS working – it takes about 10-20sec to have a 3D fix with good resolution. Up to now i couldn’t get Return-To-Home working in Betaflight 3.3.0 – i’m not even sure if this functionality is working/enabled in version 3.3.0… might have a look into INAV but right now i’m quite happy with some short/mid range flights to get a feeling for the kwad.
Realized that a 200m field is far to small for the 7 inch class next time i will take it out to some bigger playground…
UPDATE: well this time on a 250m field with 5S 1800mAh according to GPS data we got 165 km/h 🙂
Minibiggers first mid range adventure
nearly 1km away until the taranis gave me an RSSI warning. Perfect travel speed seems to be around 80km/h with about 15A draw. Have to check out why RSSI in OSD is staying constant but taranis gave me a warning at 950m.
some cruising with my old Gopro Hero 2 – badly attached with a mount from another quad – sorry for the jello
PID’s used in those flights:
Long Range RX and VTX upgrade
FrSky on 2.4 GHz can get good range but beyond 1km RSSI drops down quite fast and i guess if there is some interference on 2.4GHz with other devices like WIFI you can watch your Kwad doing the failsafe…. so… i did risk to buy the new FrSky R9M TX module and some R9 slim RX. First impressions are quite good – got about RSSI 85 on 1km distance from on 100mW.
Did replace the Matek VTX as well as it gave up to transmit after a little crash. Probably grilled itself as it took me 5-6 minutes to recover the Kwad.
My choice is an TBS Unify Pro V3 on 5V. Hope it won’t have any noise on high throttle. Had some issues with the Unify in other Kwads. It can be prone to noise.
out in the Mountains doing around 1km of distance to TX and in total about 6-8km of flight distance
Foxeer Box 4K on the Minibigger
finally went for the Box 4K as the Gopro Session 5 is mostly out of stock and it looks like the session line will be discontinued.
first test was in the late afternoon just before sun went down – and i’m quite happy with the results.
