bought a 7996 with the intention to convert it to 9V.

I am very disapointed that you can not have both of the parallel straights
switched to go straight at the same time.  The switching only allows for one to
be straight and the other must curve.

I'd be happy to know if you have a good method of splitting the controls and
adding solenoids!

Does anyone else have experience with splitting the 7996 controls, or adding
solenoids to a regular 9v switching point?

Thanks,
Scott

splitting the controls for the doubble crossover can be done in a couple of
ways. as soon as i get my hands on a set i will write up some instructions for
everyone.

as for selenoids there really is no need. automating 9v/rc switches is fairly
straight forward.  see:

start with a "z"  also there are literaly probably 100+ solutions to automate
all you have to do is look.
