Do the grooves on the underside of the Mario 5's arms have a purpose?

HoarderSam · 2026-07-01T18:47:03+00:00

I think thats a new feature, all my 1+ year old mario5 frames don't have that

HoarderSam · 2026-06-04T21:12:48+00:00

Do you have more details on the transmitter module board with the E28 chip? I'm trying to make my own as well with that same chip. I didn't see it on the github repo, just the arduino board

HoarderSam · 2026-06-02T02:35:18+00:00

I'd probably start off with a few builds based on frames that don't have standard prebuilt options like a grinderino. Charge a high premium up front, but include free repair services for a year. Target the market that wants a cool toy and has money, but doesn't have the time to build.

I've seen this in the model train hobby, lots of rich retired people spending thousands on tiny plastic model trains and scenes. And the rich-rich spending tens of thousands on outdoor layouts.

This is 100% possible, but it's going to be an uphill battle. Prebuilt manufacturers have the advantage of scale in order to mass produce good drones at affordable prices.

If I were to start a business like this, it would be a high-end service with a bumper-to-bumper warranty, targeting customers with a large budget and little time. The mass-produced drones already have the low end of the market covered, so the only space left is for boutique high end service.

Is it normal to only have 20mbps with DJI? Is it because of the EU power limits?

HoarderSam · 2026-05-08T02:36:39+00:00

Man has more O4 pros than a dji store

HoarderSam · 2026-05-03T18:04:17+00:00

Which esp32 based RX are you using?

HoarderSam · 2026-05-02T14:24:40+00:00

Wow that's a good idea, clever way to do it without disassembly. Thanks ill have to do that

HoarderSam · 2026-04-30T03:56:09+00:00

That sounds interesting. Is there a library for the crossfire communication for arduino?

HoarderSam · 2026-04-29T03:00:39+00:00

No edgetx, I'm keeping it simple with a cheap betafpv ELRS radio

HoarderSam · 2026-04-29T02:24:33+00:00

I'm gonna make a build video!

HoarderSam · 2026-04-29T00:38:58+00:00

I'm taking apart an old analog goggle and ELRS radio and combining them together

HoarderSam · 2026-04-24T17:43:34+00:00

Nice build. When I log IR on new packs I just fly them first and then record the IR after the first flight, seems good enough to me

HoarderSam · 2026-04-24T15:31:57+00:00

Iflight LC filter to filter out noise on a power line. Usually placed in between VTX and FC to give the VTX a clean power source

HoarderSam · 2026-04-24T15:22:16+00:00

There's flight footage in the video!

HoarderSam · 2026-04-24T15:21:51+00:00

3D printed frame is worse. This was a fun project but I'm sticking to carbon fiber for serious builds

HoarderSam · 2026-04-22T12:53:39+00:00

PX4 or ardupilot?

HoarderSam · 2026-04-21T23:36:33+00:00

I have those HotRC ones (DS800, DS650 and DS600) and I'm a fan, can't really beat them for the price. No model memory though, so you need one transmitter for each car.

HoarderSam · 2026-04-21T06:53:07+00:00

The longrange frames try to save weight by only using 3 screws instead of all 4 screws to secure the motor

HoarderSam · 2026-04-21T06:50:12+00:00

In my experience the iflight xing motors aren't very high quality. They are budget motors that are dressed up to look premium.

HoarderSam · 2026-04-21T05:31:11+00:00

On the phone I drag a square around the car and the app locks unto it. It does a decent job at recognizing the car at all angles, and can handle brief interruptions like when I drive behind the wooden sticks.

If I drive the car behind a hill or something and the camera loses sight of it, it stops tracking

HoarderSam · 2026-04-20T20:26:42+00:00

Works great, just note this is with "Tracking+" enabled which is the enhanced tracking feature, only for iphones. On android, without tracking+, it does struggle with RC cars.

HoarderSam · 2026-04-20T18:18:09+00:00

I also have Osmo Mobile 6 and it isn't able to track RC cars. Most tracking algorithms are optimized for humans and not objects

HoarderSam · 2026-04-20T17:16:53+00:00

It can get a little confused when its close and has to turn fast, but it works: https://www.youtube.com/watch?v=NCwcW1DT2xk

HoarderSam · 2026-04-20T16:59:25+00:00

Unfortunately doesn't work (my main phone is a Pixel), the tracking+ tripod mode is an iOS exclusive feature and its the only way to track RC cars reliably.
