The failure of the fixed-wing flight during the New Year
Increased sense of frustration
The feeling of frustration reminds me of an interview from a long time ago
The interview became a motivation for learning
Of course, it was passive
When I got home, I started studying the remote control
From the beginning
t14 t16 t20 boxer tx16s gx12 tx12
From Hall joysticks to CNC RDC90 potentiometers
The budget was originally set at 1000
But I felt it was unnecessary
Later, if I buy a real machine, batteries, and such
The investment would also be significant
So the remote control budget was reduced to 500
I can 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, 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 the existing issues
There is no perfect remote control
Moreover, second-hand is not the latest product
New ones also have a lot of problems
As some content creators mentioned
I went to Bilibili and asked a few content creators who post remote control videos
After three days, only two content 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 being snapped up
If I didn't act soon
I would have to buy more expensive second-hand ones
The 480 t20 controller head used a 90 yuan black sheep one
The bag and battery used were from Radiomaster
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 content creators suggested opening it up as soon as it arrives 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
Just a quick advertisement
