Which model or modular system did Peter Lustig use in this episode?
Hello everyone, Recently, I watched some Löwenzahn with Peter Lustig with my nieces. In this episode, he used a specific system in his final "attempt" to build a suitable bridge, it seems to me, but a Google search for such modular systems of his time, as well as the attempt to use Google's AI, wasn't…

Calibrate Jumper T-Lite joystick?
ByLuc8030
Hey, I got a Jumper T-Lite because I want to get into FPV. Unfortunately, I discovered today that the left stick has a problem. In the following video you can see that when I move the joystick up and down, this movement is recognized but sometimes a movement to the left is detected: https://www.youtube.com/watch?v=G1nY4WAPfUE Thanks…
How do I create a self-made blank virtually in a program so that I can print it in 3D?
Hello, I have a question regarding my self-made blank. This blank is a fake fishing lure made of wood. I would like to get this blank into a virtual program with accurate details so I can then 3D print it. Unfortunately, I can't simply trace it because it was sanded by hand and has a…
Reset TQI 6530B?
BySebbo796
Hello, The differential locks on my TRX4 (1:10) aren't working properly. They work, but the wiring on the transmitter is incorrect. How can I reset the TQI 6530B to factory settings? Thanks in advance
If the part is made of a drone, I would do the drone type and try to find out its operating frequencies on the net.
Purely from the board and the two wires you can neither recognize nor read it.
Yes, but frequency does nothing because the part of the type itself was installed and was not a BNF Quad
Please measure the length of the wires. Then add the length of both wires and multiply the whole by 2. The number that comes out, you simply assume as a wavelength and convert it according to the following formula:
lambda = c/f
f is the frequency in Hertz and c. is the speed of light
(approx. 3 x 108 m/s)
A frequency in the Gigahertz range may be coming out. If this is correct then I can’t tell you, unfortunately, because I just assumed for the conversion that the two wires act as half-wave dipole.
Should be somewhere. If not get away. Nen newer doesn’t cost much. Even if you find out which receiver it is needed the right spark.
Even if you know what a recipient that is need the appropriate spark.
2 antennas…Should be a receiver.
I know…. Which one?
