Not much. It was designed for relatively long flights with high speed. In 60s speed and altitude were considered much more important for avoiding AA defenses (look at strategic bomber projects and their counters - interceptors of that era). Electronics also weren't too good to allow complex remote control anyway.

There is good site (in Russian though) about military planes, and it has pretty large articles about both Tu-141 and Tu-143:

>It seems like that one got out of control

It is very old, and I guess all components already gone through expiration date multiple times.
