The failure of the fixed-wing flight during the New Year
Increased frustration
Frustration reminds me of an interview from long ago
The interview became a motivation for learning
Of course, it was passive
When I got home, I started researching remote controllers
From the beginning
t14 t16 t20 boxer tx16s gx12 tx12
From Hall joysticks to CNC RDC90 potentiometers
The budget was originally 1000
But it felt unnecessary
Later, if I buy a real machine, batteries, etc.
The investment would also be significant
So the remote controller budget was reduced to 500
I could only look at second-hand Hall versions (non-contact theory has a longer lifespan, but the downside is that there may be interference)
t14 t16 t20 all have second-hand options for 500
x9d 2019 second-hand is also 500, can be flashed, ELRS requires head support, simulator needs a dongle
boxer and tx12 around 500 are CC2500 protocol, there are also ELRS protocol ones that are about 50 more expensive
gx12 t20s are newly released versions, second-hand is also not cheap, 700-800
I've watched all the teardown videos
Looking at the motherboard design
And existing issues
There is no perfect remote controller
Let alone that second-hand is not the latest product
New ones also have a bunch of problems
Some creators mentioned
I went to Bilibili and asked a few creators who post remote controller videos
After three days, only two creators responded
One didn't understand the second-hand market
The other couldn't recommend, suggested trying boxer
When I didn't get a response, I bought the t20
Why?
I found that the second-hand ones I had saved were all snapped up
If I didn't act, I could only buy more expensive second-hand ones
The 480 t20 controller head used a 90 yuan black sheep one
The bag and battery used were Radiomaster's
The condition was a bit poor, around 8/10
In my hesitation, I found it had already been sold
I bought this 500 t20, the condition received was about 9/10 to 95/10, with little wear
It came with the original box and stickers
The original data cable was missing
A blue ordinary lanyard was included
Throttle minimum -99, calibrated twice and still the same
Not a big impact
Some creators suggested to open it up as soon as you get it to check if the wires are properly connected
Otherwise, if the signal is lost while flying a big plane
The loss would be greater
I was too lazy to open it
And I’m not playing with the real machine for now
