still holding onto analog because of these little guys. lots of fun basically anywhere!

this is the 73mm version of the frame that uses 40mm props. the 31mm version seems cool but it will be much more weight sensistive so I played it safe

the tpu camera mount is specifically designed for the runcam atom so i ended up ordering one after trying to shoe-horn different cameras in like the runcam nano 3 and the foxeer pico. don't like the narrower field of view of the atom but it's not the end of the world.

Just maidened in the house, 520mah is giving about 2.5 minutes. pretty quiet. getting some desyncs though on really hard maneuvers...pretty sure the fets are ok as the GNB27 inherently will limit the current....I might need to put in a throttle limit.

Also getting some throbbles that I couldn't tune out... this is going to annoy me. I might have to put this thing on a diet to see if it will help.
tried antigravity, playing with the PID balances and gains as well as thrust linear values. Also moved it to 48khz and bi-directional rpm filtering yadda yadda on bluejay. still throbbling....a little better but definitely there. sigh

Maiden flight done. This thing little drops like a brick the moment the throttle is cut....there is no momentum at all...very weird. I had to set a throttle limit at 85% to keep from desyncing... I'm going to raise it abit for the next flight. It likes to cruise more than being tosse about... getting about 4 min out of a 520mah GNB battery.

Cool build! Good luck with that board tho, not very good quality in my experience.

Thanks! I got it for 20 bucks shipped back in the day (july 2019). This is the third build on this board, two seasons of IGOW and it's outlasted quite a few AIO boards that I've gone through. I still cross my fingers when I plug in though, haha. It's surprising as it's kind of a hack job layout of a board. It's even got a piece meal SMD diode laying across the input terminal capacitors...I think it's for reverse plug in protection?

I guess you get lucky for the price I had to try, popped an esc skidding on the ground in a little battery bounce with a babytooth. Setup didnt draw more than 13 amps (so is said I guess it could be wrong). Hope yours keeps going.

I bet that's hella fun to fly :) I like the way you used an extra layer of heatshrink and one of the mounting screws for your FC, to mount your VTx. Very lightweight, very creative... Captain hindsight is here telling me it's an obvious idea, but I haven't seen it in this context before. Impressed.

1 was born out of sheer laziness to unwrap a previously used vtx/antenna... that second shrinkwrap was to keep the antenna on.
Annoyingly, the build was so clean up to the point of mounting vtx and rx...the reason why i love the vista antenna and one thing to mount for everything.
The ELRS geniuses need to snap their fingers and release their version of a sixty9 and make a whoop mounted edition

Jodie Froster   Nov 18, 2021 

I feel that. Everyone needs to, that's just a smart layout. Is anyone else relevant, outside of ELRS, at the moment.... Maybe not..... So yeah, maybe just ELRS needs to. I want a 915mHz version with a 600mw vtx, and I'd like it to be that 20x20 that has the breakaway 30.5x30.5 holes, just in case. I think I would also like a 1 watt vTx side version, with a flat back to add a heat-sync if I wanna.

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..
