Lil Duece OG (Favorite Quad)

This is Build #1 for the Lil Duece (OG). I built this shortly after receiving the pre-order frame (Aug 2018) and it has been my favorite quad ever since. I don't believe this is available from the website anymore, but other vendors do keep it in stock. I recommend using the new 2019 'No Limit' frame direct from Lil Duece FPV to take advantage of some new design features, but this is on the OG frame with the acro mount.

Fair warning, this build has taken many many different variations, from DSM2, DSMX, Frsky, nearly a half dozen cam/vtx combinations, numerous props... Truly, this is a testament to how durable the frame is...I don't even have a tiny imperfection on this frame, and I've flown it non-stop into walls, trees, 400' freefalls...you name it. No damage. It's amazing.

This build weighs, depending on your choices of filament (prints), hardware, receiver, wire length, and battery, about 60g. Yes, it's light. Yes, it's nimble, and yes...it's a cheap build. But enough of that, lets get to it!

Solder motor wires from the inside to keep the build clean. Some actually choose to solder motor wires to the bottom of the ESC, but my preference is the top and compress them in with the FC. Same with the solder connections to the aio - solder from the inside. For the receiver, however, I store mine between the frame and ESC, so a direct feed from the FC to the receiver is clean and works well.

The FC and ESC come in a stack much cheaper than if you buy separately, so the FC option listed for $23.94 is actually the stack.

Motors, props, and batteries were all gotten on clearance deals, so many are no longer available. Any similar spec would be fine. I personally use a Molex 51005 connector on this build.

AIO used has changed over time, but most were just pieced together from broken bits. My personal favorite right now is the TX06 (gotten on sale for under $10) due to the smart audio. A switchable vtx is obviously better, but this works just fine.

Use metal screws (from the motors) through the frame to prevent having to replace nylon ones every time you crash out of a tree (which apparently happens to be often for me). M2 5mm are what I am currently using. You can use metal standoffs, but the mounting holes on the Super_S are in the circuit, so you can't touch two boards together. Two nylon standoffs and the bottom metal screw seems to be the perfect config for my needs.

cool build - you running 8000kv motors or 10000kv?

mbrulla   Jun 02, 2019 

Thanks dude! The deal (12 motors for $30) was only on 8,000kv, but they have plenty of power to handle a 550mah 2s!

Yeah I bought the same deal a while back but haven't used the motors yet, good to hear :D

They don't last forever, had to replace two on this build, but they are pretty resilient. I'm looking to find the replacement bearings for them, actually. If you ever want to unload them let me know. I think these would be great on the Mobula7 HD to help prevent burning the boards out (the HappyModel replacements are 9,000kv, but I'm a "safe rather than sorry" kind of dude).

do you try out e few props?
i fly something near, i try some gemfan, eachine fourblades, the fourblades on yours... my best results i get with my kingkong 1940 triblade. if you could share some impressions about props would be nice.

I have tried many props, I only listed the two that I liked the most, but realize I also omitted one other (2" Cyclones are also very good, and more robust than the 2035s that easily bend).

The biblade Lumenier Bowties are my favorite. Great thrust, very light, durable, and cheap. I wouldn't go under 2", personally, so 1940s are going to be missing power.

I also tried AVAN Rush 2.5" (will post in my second Duece build, once I go and type that whole thing up), but found that on 1102 motors it is just too over propped. There's almost no punch, though they are incredible stable and smooth.

I am going to pick up another set of the 2" Cyclones, as I really liked those, but my daily props are the Biblade Bowties.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
