DOES ANYONE KNOW WHERE YOU CAN BUY A RADIO CONTROLLED SUBMERSIBLE REPLICA LIKE THE ALVIN.

CHEERS!

You might try some of the Nikko subs, available at Tower Hobbies, or at walmart.
The e-store associated with this forum may have them also.
They go forward, and backward, and up and down.

If you are looking for something more scale, and with more functions, try
going to http://www.subcommittee.com/ and making some inquiries.

try fx models!! he has a real nice alvin
