Well I'm open for persuasion, but 8x4cm front face ... and how deep?
Here's my cockpit ...
and this is what's behind the panel ...
I still don't see where I can fit one? Also what power consumption? and where is the best aerial placement to avoid fried b@lls? So out of interest, what was your little taildragger and where was your transponder and aerial fitted?
As for cost? my T31m cost me around £2500 to make, and I figure an annual flying budget of around under £2k to inc maint and insurance for up to 100 hours.
All that aside, I've been flying since 1986 and I'm still here having rarely flown transponder equipped aircraft.

PS. Sorry to be party to dragging this thread back to yet another Transponder/TCAS debate ... grrrrrrrrrrr
