Tinypick vs whoop pick

Why, oh why, am I so attracted by Nanos?

My friend asked me to transfer his frefly to a whoop. I used that opportunity to build my own
I went with a Betafpv 1s ELRS board and a light external 400mW nano vtx. Coupled with a nano3 and some 0802 22000 kv, I should be getting a lighter and more powerful quad...
remarks

  • the nano3 is too small for the canopy. Had to glue it
  • had to flash 4.3 to get elrs 2.x...
  • tune with 4.3 is fairly straightforward (1) whoop preset without esc telemetry (2) decrease master P/D (last slider) to 0.7
  • used ph2 solid pins to avoid changing all my 1s batteries to bt2.0

This thing flies fast... but still lacks power when coming down from a powerloop. Very very quiet. Funny flyer.

After 6-7 packs the ESC blew up (I was changing the battery when magic smoke happened

the whoop
The cam angle is tough for beginners
Had to flip the AIO
Had to drill 1.5mm holes to pass the M2 screws into the canopy
Stock tune on 4.2 is good

UPDATE
BETAFPV kindly replaced the burned FC as it failed within thir new 30d warranty period. The new board has been good and works perfect. It's really good to see Betafpv going in such direction.

Here's the tune with the exchanged betafpv 1s FC. Flies good, no vibrations but still some propwash on split S when I don't give enough throttle. This is basically a 65mm whoop tune

Did you switch to another FC model?

Nikotttin   20 days ago 

Betafpv kindly provided me with a new FC as part of their 30d warranty. The new FC has been going strong with the tune pasted above. I have now probably 30 flights on it.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
