|Small Weights on Plastic Clock|
To test out the Micro DT I decided I would install it in the free flight hi-start glider that Hank had shown on his website with the timer, the Retro Gnome sold by Retro RC. I met Mark Freeland (Retro RC) at the 2016 Nats and he showed me a sample of the glider.
Building the kit is relatively easy as it is laser-cut and there is an instruction manual, in some places the plans and pictures are a little small so I used a magnifying glass, not going to say I am getting old. The wing seemed like it was not very rigid before covering so I used a technique Dohrman Crawford uses of using some reinforcing tissue strips over the structure before covering with tissue. The finished wing feels plenty rigid.

This glider uses a simple autorudder that is pulled to the right by a small rubber band and to the left by a monofilament line with a pin holding the tension until the pin is pulled out as the tow hook releases and the tow line pulls the pin out. As this is a hi-start glider a very thin rubber strip and line with a small flag make up the hi-start launching system, I purchased this from Retro RC also.

My hope is to do some glide testing of the Retro Gnome this weekend and take additional pictures but no hi-start launches. The glider must be adjusted so that it goes up on tow straight, when the pin releases it should turn right because of the autorudder. The design includes adjustment screws for rudder movement, stab incidence change, stab tilt, and a tow hook that can be positioned in multiple locations.
Stay tuned for future flight reports.
