3 inch vs 3.5 inch frame what's the difference

Hi everyone,

I'm planning to build a sub250 analog freestyle quad during winter time. Due to the weight limit I'm struggling to choose between 3 and 3.5 inch frame. I wasn't able to find any specific information about the difference between these two sizes. Naturally bigger frame means bigger props, bigger punch and momentum. But how these difference appears in daily flying?

Budget friendly reliable hot air station

Hi everyone,

I'm looking for hot air which will not ruined my budget. I know that quality come with price but I'm just tech enthusiast. I'm planning to use hot air for such tasks as USB-C or HDMI replacement or desoldering analogs. As a budget option I found: Fnirsi Sag-55 and AIFEN 858D. Also I heard that atten st-862d is great choice but it is significant more expensive. I'm not planning to use hot air every day. So what would You recommend?

Thanks

Is that best soldering iron in 50$ price range

Hi Guys,

First of all I like to point out that I'm a newbie in soldering however I practiced and I can say that I'm getting better and better. After using the cheapest soldering iron from the local market I decided to buy something a little better. I thought I would try the T12 soldering iron. I like to buy Quecoo T12-959. I have three questions:

- Is there anything better in this price range?

- If not, which version should I take? There are two: one with a metal "M8" handle and the other with a "907" plastic handle?

- Finally are these devices safe? I read that they have issues with grounding?

Thanks for all the help. May Your solders be shiny ;)

Looking for high-quality local hoodie - Windhoek

Hey everyone,

I’m currently traveling around your absolutely stunning country and loving every moment of it. I’ll be in Windhoek before flying out, and I really want to take home a quality souvenir, I thought that a cool, well-made hoodie will be perfect.

I’d love to support local Namibian brands or independent designers rather than buying generic tourist merch. I’m looking for something with a bit of "Namibian soul" — whether that's a local streetwear brand, a boutique label, or quality local apparel.

What homegrown clothing brands would you recommend, and where in Windhoek should I look for them?

Thanks so much in advance for any tips :)

Fried GPS?

Hi there,

While I was building my first 5 inch quad I made a rookie mistake and I plugged my GPS using a pre-wired connector that had reversed polarity out of the box (5V and GND were swapped). It obviously wasn't showing up in Betaflight. Before I noticed and unplugged it, the module got noticeably hot, but there was no smoke or burning smell at all.

The drone hasn't flown yet, but it connects normally to my radio and Betaflight. It arms correctly and responds to all transmitter inputs without any issues, so the FC seems to be working perfectly fine.

I also checked the voltage on the 5V pads with a multimeter. The pads I could easily reach showed a solid 5V, but at the very end of the GPS cable, I was only getting 4.7V. To make matters worse, while probing around, I think I accidentally caused a brief short near the buzzer pads with my test leads. The drone beeped, LEDs lit up, and it seemed to reboot itself. It still acts completely normal and connects to everything, but I'm a bit paranoid now.

I have a few questions for anyone who has dealt with this:

Is the GPS dead for sure? Is there any chance it survived the reversed polarity, or is it a lost cause?

How can I safely test the GPS? I want to check if it still works without risking a short on my FC.

How to verify the FC? Even though the FC seems fine, what is the best way to make sure the UART and 5V pads are 100% unharmed? And is that 4.7V reading at the end of the cable normal, or a sign of an issue?

Should I be worried about that accidental short? Since the FC rebooted but seems perfectly fine now, could I have caused any hidden damage to the flight controller?

Thanks for any help

Diversity Antena mount question

Hello,

I'm planning to build a 5 inch cinematic quad. Because there wasn't a significant price diffrence between normal and diversity receiver i bought a radiomaster rp3. Now I'm thinking about how to mount it. As I said I'm gonna fly mostly cinematic with ocassional freestyle, nothing fancy, definitly not that wild bando freestyle. Also my build isn't long-range. To be honest I don't know how far can I fly with DJI o4 and rp3 but I'm not gonna test it. I'm just looking for reliable solution so I can fly without worrying about ELRS singnal.

I read an Oscar Liang article about antennas, I understood that best option is to mount one antenna horizontally and one vertically. So I'm thinking about mounting one on back of the drone and one on these side panel, I try to show it on attachment. Is these good solution? Can vertical antenna be so close to o4 unit?

Maybe I'm overthinking it and I can just mount both of them on back of the drone horizontally and don't bother anymore.

Thanks so much for your time and answers. I really appreciate it.

Hi Everyone,

Yesterday day my whoop arrive since them I'm flying it and tuning. There is one thing that bother me. It is safe to fly constantly with vtx power set to 100 mW. I read that 400mW can fry the board and drasticly lower fly time. I don't need that much power but 100 mW seams to be the sweet spot. I really appreciate all answers. Also thanks to all of You for lots of knowledge gather here. On picture is my set up ;)
