Greetings to all ,

I am seeking constructive criticism of my solder joints quality.

I have used a T12 D12 chisel tip on hglrc rc2 soldering iron to solder all these and it was too big for the smallest pads.

I am sharing pictures of solder joints of firstly 3 really tiny pads for connection to 28awg wires of a nano fpv camera having 3 wires for video,5V and Ground.

Next i have soldered two 18awg wires connected to xt30 connector to the slightly bigger pads to power the board joints from a 2s lipo battery.

I have used a multimeter to ascertain There are no shorts anywhere and used a fancy fuse device or a smoke stopper to power and see the board's functioning without it smoking .

Hi everyone, sharing a couple of older circulation coins I have.

• 20 Paise (1985): Hexagonal shape. Based on a quick Numista search, this series is minted in an Aluminium-magnesium alloy.
• 10 Paise (1990s): 8-scalloped shape, also an Aluminium alloy. The last digit on the year is a bit worn (looks like 1992 or 1993).

How I acquired them: I actually stumbled across these while cleaning up my room. They were buried right in the middle of my hand tools bag .

Specs: I don't have a precision scale or calipers to give the exact gram weight to two decimal places or exact millimeter diameter at the moment (apologies to Rule 6!), but they appear to be standard circulation strikes.

Would love to hear any historical context or interesting trivia the community has about these specific mint runs!

I fly quadcopters like 5 inch and tinywhoops and this flying wing 🪽 is my first fixed wing build for fpv flying.

I’ve already tuned elevon throws down a lot in iNav because defaults felt way too aggressive.

Before maiden, what important things should I still check or complete?

Questions:

- Are 8–10mm roll throws and 10–15mm pitch throws safe for first flight?

- Is 6° level trim too much for a flying wing?

- Any critical iNav settings/checks people forget before maiden?

- How risky is auto-launch for a first-time wing pilot?

- Should I maiden in Manual, Angle, or launch with stabilized mode?

- Any recommended expo/rates for first wing flight?

- Is a vertical VTX antenna connected to speedybee tx800 on top hatch okay for FPV video link reliability?

-what should be size of the ground for safe takeoff and landing?

Also I have reinforced fiberglass-style tape with netting in it.

Should I reinforce:

- wing tips?

- leading edges?

- elevons?

- belly landing areas?

- motor mount area?

Or will the extra weight hurt more than help on a 620g setup?

This is literally my:

- first RC plane

- first flying wing

- first FPV wing

- first hand launch

Trying to avoid turning the maiden into confetti 😅

Earlier i used some no name brand soldering wire with no rosin core and it didn't melt well even at 450 degree Celsius it just created dry joints but now the pool being created is at 380 degree Celsius.
