Ummagawd 2Fiddy - Walksnail / 4"

By McLogo76 on Dec 29, 2022

2 153 4

I got this Ummagawd 2fiddy from my mate SamW85 and converted it to Walksnail.
I initially struggled a but with the 5" props so I changed to 4" HQ 4x2x3 and it handles no much more to my likings.
The quad can now be "thrown" over obstacles and the props do not brake or pull down when inverted anymore.
Really like how it flies.

Update 19/02/2023
I finally found some time to convert and upgrade it fully to a proper Walksnail quad:

Swapped the AIO to a Jhemcu F405 Pro 40A and changed the arms to be under the frame to make room for the AIO / Walksnail VTX sandwich.
3D printed a remixed mount for my new Caddx Peanut and also printed a arm mount for the ELRS antenna.
Updated to BF4.4 with HD custom OSD

I will test the build next week if the weather is ok and upload a better vid than the initial one. Also thinking about testing 4S 850 packs additionally.
More to come...

Awesome build!
what the auw?

McLogo76 Dec 30, 2022

Still too heavy for sub 250 to be honest: 194g AUW and 273g with a 4S 650 Tattu lipo.

Ifly@sgfpv Dec 30, 2022

its kind of hard to keep it sub250....too much compromises...

McLogo76 Dec 31, 2022

I would need to use lighter motors etc. but not sure if I'll try to get it under 250g anytime soon...

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..
