Hi Cees,

Your yellow metal case transmitter seems to really have been used alot. The most sturdy antenna mount I have seen on a hand held transmitter. How does it look inside? So You built ityourself? (as I understand it from your previous post you made a copycircuit board of a Simprop transmitter and mounted similar components on the board and used that in your yellow transmitter case). I see you used Simprop sticks also (at least they are verysimilar)- image below of a Simprop alpha 2007 from Simprop catalog 1973 where You can see similar sticks.
