I really like my 3" toothpick and i thought is worth building a more sturdy one.
Has some weight, similar in a way with a 5 inch and not as agile as a toothpick.

Slapped a tinytrainer pid tune on it and flies like a charm.
Will swap the walksnail vtx with a 1s version to make it a bit lighter and to an expresslrs when i get my boxxer.
Also, will need to print a camera adapter to get rid of the bars in the video feed.

Flight time up to 4:30 mins on light freestyle.

Camera adapter to keep cage out of the image can be found here

I'm in the process of building a tadpole hd with the walksnail 1s vtx and have the bars from the cam mount in view. Where did you find the spacers to move the camera forward? Tried looking on thingiverse but no luck. I would like to print the spacers for my build but cant find a file, would you mind sharing the file or a link to it?

I found the file on thingiverse and will print it tonight. I have the 1s version with the nano camera so this is just what I needed. Thanks for the file!

That footage looks amasing! Walksnail is something else! It also looks like a place I used to live in Scotland :)
I've got the 1204s on mine and it doesn't respond anything like your build. Looks really well setup.

if you're on BF 4.4 try to apply five33 tinytrainer pid preset, it worked really well for me. The footage above it s on stock bf settings, i managed to get it flying much better with the tinytrainer preset. i would suggest running the 1404 motors, they do feel very good.

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
