Description
Forgot my radio… so I crawled the rock pile with my PHONE
In this video:
App Drive in the R/C Trailink app: no radio needed
Throttle under one thumb, steering under the other
One-finger vs two-finger mode
Raising crawl current right from the app
Honest numbers: about 20Hz and roughly 0.1s latency
Verdict: it won't replace a good radio, but it's perfect for "oops, I left my radio at home" or a quick bench test.
Get the app:
The R/C Trailink app is out now on Google Play and the App Store.
Search "R/C Trailink" and try demo mode.
(App Drive isn't in the public app yet.)
