New unexpected problem.

I have not been able to find socket headers that are compatible with the solderless proto board technology. All the headers are designed for PC use. This makes it very difficult to connect my six pin 0.1" centers USB connector device. It also makes it difficult to connect the servo PWM three pin cord, the Electronic Speed Control three pin cord, and the connectors needed for the radio receiver three pin male headers.

I could cut and strip six 1/2" #22 lengths of solid #22 gauge wire and stick then into consecutive holes. The female connector would come in perpendicular to the board.
This is not as reliable as 90 degree square header stock, but what choice do I have?
Remember this is for middle school students.

Suggestions anyone?
