TMac's Tadpole

Initially used the BetaFPV Toothpick F4 AIO 20A flight controller/ESC board so I could also try out the Caddx Baby Turtle Whoop version in this build. Wiring diagram below shows the Baby Turtle connected to AIO board. I have subsequently replaced the Baby Turtle with the Baby Ratel and am using the Insta360 GO for my HD video. I've also re-oriented the VAS XFire Pro 900 mhz antenna from the way it is positioned in the picture (vertically) to a horizontal mount on the bottom of the frame (needed more room for the top mount battery when I started strapping the Insta360 Go to the top plate). 80 gram dry weight. 136 grams AUW with GNB 4S 520 mah LiPo. Getting over 6 minutes of good flight time (not taking it easy) with 48Khz PWM JESC and RPM filters.

That's a pretty impressive build man!
I was a bit concerned about the thrust/weight with that heavier component choice but then 6mins flight time is very nice
I got a 3" coming together and could only get 520mah 3S; wish I could have had 450s but I'm not worried anymore :)

Thanks for sharing, sick spots too btw, cheers!

Awesome frame and build.

So... what battery do you use? what is the final weight and how long are your fast acro flights?

different size batteries (whatever i have charged up at the time!). usually 4S 525 or 650. I get about 5-5:30 carrying an Insta360 GO all the way up to about 7 minutes without the GO.

You have any flight footage? And would you change the motors/props for a Tadpole 3"? That 6 min flight time sounds nice!

Hey sfonkter! Yep, got some flight footage for you here:

IYes, I would use different motors on the 3" version. Maybe some 13xx-14xx motors. I've also got this weeks video (comes out Friday) on my YT channel ( ) about the frame I designed earlier this year - the Rattler. Its one of my builds on this Rotorbuilds site too. Video Friday is updated design. May want to check out the video next Friday (Sep 4th) for a nice "little surprise" too!

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..

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..
