Somebody on RC Groups asked about attaching the control rods on the Blu Baby. Here's how I did it, with the control rods on the outside. It doesn't look as nice as running the rods internally, but it's a lot easier. I wanted the control rod to be as light as possible, so I used 1mm carbon fiber rod, running through plastic coffee stirrers.
The servo attachment is a straightened paper clip with a Z-bend. I put both the CF rod and the paper clip into 1.5mm shrink wrap, and added a couple of drops of CA. Heating the shrink wrap gave a very tight, even connection between the two surfaces for the glue to bond to. Any excess CA will drip out when heating, so be careful.
Green note: These are recycled coffee stirrers that were used to stir organic half and half into free-trade organic coffee!
