First question is why would you want to build your own Tx?
Whilst building transmitters (and receivers) from components was not uncommon when I started with planes (don't ask how long ago) modern gear is so good that there is little reason to try and build your own (except maybe just for the h*ll of it).
If cost is the issue you are probably better off looking for a second hand Tx, with lots of people moving to 2.4 there is a lot of cheap 36Mhz gear around over here, I assume it is the same with in En Zed!

Long long ago in a far off distant time there was a place called Heath Kit that offered a build it yourself TX, even a tach. One of my friends fathers started with the kit and I have his tach today. Like all things of the past, kits and electronics that we made ourselves, these are things I haven't seen offered in decades. For those of us that enjoy building and tinkering I wouldn't even know where to look these days for the components to do it. Radio Shack is now a place to buy toys and cell phones and if you ask the hired help for anything in the electronics section {what there is of it} they sort of point you to the drawers and let you fend for yourself. All I can do is wish you good luck. I can understand your desire but these days building anything yourself is becoming a lost art. I don't think they even teach radio shop in schools any longer, or much else.
