All-arounder 2,5" 4S on Walksnail
By mateuszjasek on Jul 17, 2024
I've been working on building the perfect all-around quad for my bike trips, focused on cruising with smooth, cinematic footage and no props in view. After some research, I decided on the FI-118 frame, which might not be well-known but has a great design for my needs. For night vision, I went with the Walksnail Pro camera, and for range, I chose the Walksnail 1S VTX V3 (500mW) than v1/v2 (350mW) along with a ExpressLRS receiver featuring PA and LNA.
This setup has really exceeded my expectations. The flight is super smooth and cinematic, exactly what I was aiming for. Plus, the GPS has been rock solid, giving me that extra peace of mind. Managed to get as far as 1km without any issues with LOS. The balance between aggressive flying and efficient cruising makes this quad super versatile.
Loving how this build turned out!

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..

Nice build. What GPS receiver are you using? How many satellites does the receiver pick up?
I just updated build info with Gps receiver i used. I'm getting 6-10 satellites depending on the day. It takes around 2-3 minutes to get cold fix.
Thank you. I thought that there would be few satellites due to walksnail interference.
It's still performing worse than m10 gps on my 5" quad with full sized walksnail v2 vtx, where i get 15 sats instantly. I guess it's because of smaller gps antenna and closer distance to vtx. m10 mounted on arm of my 7" gives me even 30 sats. I set GPS_RESCUE_MIN_SATS = 5 to be sure that i don't lose gps rescue ability in poor signal reception conditions.
