I've seen a few pages of simple designs like this one. (http://members.shaw.ca/novotill/RcCarsSimple/index.htm) that are interesting.

I guess you know that most designs get all the amplification they need from just a second transistor, so what is the idea to try an op-amp?

I would like to try making an IR rc control unit for indoor micro sized planes but that's down on a very long list of ideas I'll probably never get around to. Here's what I mean: IR RC - very small! (http://www.didel.com/slow/mirted/MIRz.html)

I have also played with 433Mhz RF for telemetry from 1/10th scale model cars and slot cars.

Please keep us updated!
