The tamiyas especially the older ones are not known for handling alot of power. If using nimh a brushed system should be ok. If going lipo a very mild brushless system could be alright (low kv or high turn brushless motor).

If you do not mind brushed these are not bad they have worked fine for me.

Cheap combo have not tried it but does not look too bad (if anything the esc should be a keeper). Slower than the reedy radon.

These servos I have used or are using are not bad either.

Standard servo a little slow but works

These were just budget options.

I am also a casual driver as you say I do not go racing at the race tracks.

There are better options out there and more expensive ones too. For every brand or model you will have people rant or rave about them.
