Hello

I just subscribed this forum, i am completely new and "ignorant"

I have also the vintage original Nikko "Exploration Submarine" RB2110. It must be one of the first ones, because the date noticed on it is: 1983.

Unfortunetly the radio controller is missing, the propeller is broken and the rubber seal had completely hardened and dried out and leaking. So I have several questions.

Is it possible to find parts of this sub? If positive, where and how?
Does there exists a schematic diagram of the electronic parts (receiver and transmitter)
Can I use a another radio control device (i still have a "polistill" device on 27 Mhz)
Are the crystals for the 27 Mhz still available?

I am completely new with radio distance control, but have good experience with electronics.
So I found out - with my hf generator - that the receiver and the motors are still working!

Every advice is welcome
