Ewald 26/11/2020
Awesome little DJI drone, needs some tuning however to run nicely on 2s indoors. The flight time of 4 mins with suggested battery was too short for me, so I use 650mah 2s batteries and flashed 48kHz JESC firmware for 6.5 mins racing and 8.5mins cruising! I cut of the battery holder, mounted 2 anti slip strips and added a battery strap to fit the larger battery flat to the bottom of the drone for better weight distribution. I reduced the overall weight by modding the Caddx Nebula by removing the lower 3 heat sinks (see Vista Naked Mod on YouTube). Overheating is not an issue and flight characteristics are a lot better. To further compensate the heavier 650mah battery, I set Throttle Mid to 0.75 and Throttle Expo to 0.5 for rateprofile on Betaflight. Have not tried 3s yet, as I use this tiny drone mainly indoors.

  • Ewald To prevent automatic calibration when arming (which is annoying if the drone cannot be placed horizontally), enter "set gyro_cal_on_first_arm = OFF" without quotes in Betaflight CLI and calibrate the gyro sensor on Setup page.

  • Saari Thanks for the hints. I received mine yesterday and I think I'll go with JESC & naked Vista

  • Ewald I have now mounted the lollipop antenna with zip ties to the canopy for better reception on 1200mW 50mbps, as I now also use this drone a lot outdoors on 3s 450mAh with a new PID tune that can also handle windy conditions. In the next comment are my BF 4.2 settings (to fully benefit from the new CLI dump you will have to update Betaflight on the drone) on JESC 48kHz with RPM filtering.
    Don't let the high PID terms fool you, the P16 can handle it well. With them, on windless days the drone feels absolutely locked in outdoors. Freestyling on a small scale is possible! Also high dives and letting go of the throttle to let yourself fall without a lot of propwash is possible. When it's windy the drone will get thrown around of course as it is lightweight, but the wobble is kept to a minimum with this tune.
    I now also only use 3s 300mAh indoors and ditched 2s completely. To manage the 3s power I use a throttle cut of 75%, it's also in the CLI dump below. Way better handling on 3s!

  • Ewald BTW, if you want to improve your DJI video experience, buy the new Nebula Pro camera (without the Vista transmitter). It fits perfectly snug into the original canopy camera holder. This enables a much better FPV feed (I love the new crispness and colors), switchable aspect ratio between 4:3 and 16:9 plus high quality mode where you gain a little bit of latency but a much better picture. I really recommend it!

  • Ewald I forgot to mention, for inside I use reduced D terms for PID tuning. This way the drone is more responsive (which is important in small spaces):
    set d_pitch = 109
    set d_roll = 99
