Hi all,
maybe this is limited to the German community, but many LEGO fans there dislike
the idea of using the smartphone to control LEGO models.
Especially when it comes to trains (and kids being involved in playing with
them), many do prefer a remote control over an app.
Unluckily the 10277 is intended to be driven via such app system only. And I do
only own one phone, but have 7 PU trains at home...
If you use a regular train controller on technic motors, it will only act as a
"bang-bang"-control with 100% speed in the one or other direction. Magnets and
even the internal ball joints in the crocodile will detach in result.
There are two options to control your Crocodile with smooth acceleration:
1)
Create two shortcuts in the supply cable of the motor. Takes 5...15 minutes of
work and is reversible. The shortcut mimics that the technic motor is a train
motor and can controlled in 10 speed steps.

2)
As most of the LEGO stuff and software appears to be open source, some talented
IT specialists have prepared an app to overwrite the software on the hub (that
"intelligent" bluetooth batteriy box.
Once it is overwritten you can run it as before, but you can hook on two train
motors (either running synchronous or even better in opposite direction but same
speed). And you can hook on the crocodile with technic motor and it will operate
in speed increments that you can even modify within the software if you like.
I tested this for the maybe more interesting approach 2 motors in a train
engine; making it stronger than ever.

Pybricks Software allows the player to control Lego models via the PU train
remote control.
It can either:
A)
drive two motors synchronously
B)
drive two motors sync. but 1 forward 1 rearwards (like done above)
C)
drive technic motors (drive Crocodile via Remote Unit with many speed steps).
No Smartphone and App needed in play.
First time the hub's firmware needs to be exchanged. That is the only and last
time to deal with mobile and Apps. (Best case less than 10 Minutes).
A good collection on this topic is collected here at 1000steine in this thread:
(unluckily in German, but Google translate is your friend).

Feel free to check out other content uploaded by user Lok24 at 1000steine. He
did a lot of promotion and interesting stuff with PU and modified software.
