Tank 3869

[Cshaffer]

This tank I was not able to open didn’t have a long enough screw driver to get the back two screws out.

Heng Long Jagdpanther.

Heng Long, Jagdpanther, 27Mhz, looks like plastic sprockets/idler/tracks.

Unknown MFU, but likely an RX18. Will have either plastic or pot-metal gearboxes.

The Number 17 decal/image was added to the back of the casement (next to the large loader hatch).

My 2-cents and wild guesses: On the bottom of the Jagdpanther, I see the sticker for the No. 3 crystal. That means that the corresponding transmitter should have a No. 3 crystal in the lower right front, too. If I am remembering correctly, having the corresponding crystals and the three-way switch in the correct position will make the tank and the transmitter communicate correctly. Someone with more recent experience with HengLong RX13 or 18 and a better memory may want to jump in here and check that I am correct.

I believe, too, that the number 3869 is actually a HengLong stock number, not any number the Germans ever used. HengLong had/has a habit of providing these press-on numbers along with the crosses (Balkenkreuze), etc. As Jarlath already said, the number 17 on the rear of the casement is something apparently not original even to HengLong. Could there be a transmitter with a corresponding "17" on it? Maybe the previous owner did so to keep corresponding transmitters/tanks straight.

Non of the remotes where labeled but I do have one that made this unit run not sure on why the 17 though

An image of the remote can also help determine the type of control board.
Example.
Does it have a 3 position "channel" Switch? or a removable Plug that has the corresponding 27Mhz Crystal on it (where the switch previously was)?

[Cshaffer]

They are the 27mhz crystal controllers
