Great result ....

Thank you 🤩

[@lokaero]

Bro, everything is fine, but for the soldering part, include more flux and the finish of the soldering should be round mirror finish, like you need to be able to see your face in it. cover more surface area as possible and immerse the wire conductor as much as possible into the solder.

[@fpv-geek]

Many thanks for your tips. Unfortunately, my solder joints really don't look that good. But I'll try again with more flux. Do I have to desolder the areas first, or can I simply apply more flux and re-solder?

[@lokaero]

@@fpv-geek You could add flux on the existing joint, and add some more lead. But for a clean build, remove all the solder joint and re tin then solder again with flux. Mr.steele has made a video specifically on this. it can clarify all of our doubts regarding soldering.

[@fpv-geek]

@@lokaero Many thanks for your tips. I will try to re-solder it

Sure. I updated the description with a link to thingiverse ☺️

I built the same drone... But can i know about the tuning u did on this drone???

[@fpv-geek]

But of course. I spent many hours tuning the copter with PIDToolbox. What exactly do you want to know? Did you use the same motors and flight stack?

It depends on your receiver module. which module do you use?

[@fpv-geek]

What do you mean?

[@sparky7730]

Hey man. I know there is a ton of information online on what to buy when getting into FPV. I live in Germany too. I have a budget of 1.5 - 2k. What would you recoomend me to buy (also equipment to build)?

[@fpv-geek]

Want to get started with a 5-inch FPV drone? There are ready-made sets to buy. You'll get there with your budget. Otherwise, look for a Tinywhoop set. Like the Cetus X from BetaFPV. That's what I started with. I also have a crash compilation on my channel of this drone. Such sets are available for around 300-400€. They're all good for getting started in the hobby ☺ If you have any questions, just let me know.

[@_Elix_]

"ultimate freestyle build " while having a dji 03 on a deadcat frame and a variable tilt mount at the font is a crazy thing to say lmfaooo

[@fpv-geek]

Would you say that an X-frame makes that much difference? And what's the problem with the O3 and a variable tilt mount?
