Bit perplexing, as you stated the
Tello was shelved for two months yet multiple symptoms appeared on the first flight...
Drifting and not holding position is indicative of a VPS issue. No VPS error messages appear on the app during the (short) flight time? Suggest you try
@umanbean's VPS cleaning tips first and report back.
You noted the version of the stock Ryze
Tello app (1.3.0.0). Are you using TelloFPV as well? If you're switching between apps during the same flight, the VPS stream can get
confused. Best to power down/up the
Tello on each app use.
In RC helos, quadcopter FPV units, etc., there is a discrete Flight Controller (FC) and Electronic Speed Controller (ESC). Short of explanation death by PowerPoint, the ESC integrates with the FC to translate throttle (stick) movements to vary the speed (or voltage) of the motors to spin faster/slower. Believe on the
Tello, it's all integrated on the circuit board so not something's that replaceable except the board itself.
Here're some reference links to your questions:
