Here is a snap of where inspiration is drawn from. I tried to get a good cross section of classic American and even a couple Canadian radios too see production techniques, variations in products and really get the vibe of these gems.
The Spektrum DX7 is a great workhorse and shall be part of the stable once all the design work is done. The herd will be culled at some point but there a few guys, like the S&O and Proline SS, that are going nowhere.
The strange one in in the middle is no classic just an homage to the greats and something that I like to fly :-)
Have a great one,
