It's essentially just a Firefly 2S Nano Baby 20 analog, converted to DJI O4 Lite. A fantastic 2-inch quad that only gained 1 gram with the O4 Lite upgrade.

What an amazing time for this fantastic hobby! I absolutely love flying in the yard. It's incredible that digital FPV is now possible on such a small scale.

Thanks to its lightweight design (77g AUW with a 660mAh GNB LiHV), it offers impressively long flight times and minimal damage to the drone or surroundings during impacts. ;)

That sounds like an incredible upgrade! Converting the Firefly 2S Nano Baby 20 analog to the DJI O4 Lite while only adding 1 gram is a great achievement. It's amazing how digital FPV has evolved to fit into such a compact form. The lightweight design and impressive flight time with the 660mAh GNB LiHV are definitely game-changers, and it's great to hear that the drone remains resilient during impacts. It's always awesome to see how technology keeps pushing the boundaries of what's possible in this hobby. Keep enjoying the flights – sounds like you're really making the most of it!

I have all the parts for this build, but what canopy is this? Please, point me to the right direction!

The model is a bit rough but it does well.

Looks good! How complex was the tuning, do you have a preset?

Sebfbr   Jan 28, 2025 

I used the Nano Baby 20 preset from Flywoo with a few minor PID adjustments.

The user is purchasing Happymodel EX1102 10000Kv motors, citing their comparable stator volume to the HGLRC Specter 1003 10000Kv. This likely relates to a drone build or modification, prioritizing motor performance and size compatibility. I wonder if they're using this drone for recording videos of playing Monkey Mart game.

It's great to see you're passionate about FPV! Converting your Firefly 2S Nano Baby 20 analog Sprunki Mod to the DJI O4 Lite is a worthy upgrade.

I want to do this to mine Baby Nano. Do you have a print file for the camera mount?

WHoow. Is it good for freestyle?

what's it like flying with a narrower angle of view? i have an 04 lite on the bench, but i haven't decided where to put it.

Not the best experience so far. Disabling EIS makes no difference in fov for me. so I would guess there's a bug which crops the frame nonetheless? 4:3 is "okay", 16:9 is horrible.

Very nice! what's the throttle hover %?
I have 19000kv 1002 motors with 1s and I'd like to put them with 2s. Do you think is possible using them 2s with a throttle cup?
thanks!

Nice

Thanks! Hover is pretty low. Around 20-25 percent. I don't see a problem with 19000kv motors, as long as your FC can handle it. Try a 60-70% throttle cut and keep an eye on the amps. This quad is already pretty fast on biblades.

What a time, indeed!!!!
38 grams, digital, brushless, ELRS. WIld. Actually looks decently durable. I have been flying my 4" 4s on 03 around the house/yard, and the video is amazing but it's too fast sometimes, this looks perfect. You may have just planned my next build for me!

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..
