Not so fast Stephen, there is still a whole pile of finishing and radio installation to do. However I hope to have the Skylark in the air by Easter. :) :) :) :) :)
The plans for the next project are already on the drawing board! :shock:

I have now returned from a month sunning myself on a rock in the Atlantic and at last I can report further progress on the Skylark.
This afternoon I have installed the receiver and all the fuselage servos as well as the wiring harness. In the photos you will see the receiver mounted up at the top with the elevator and rudder servos mounted below. The servo lying on its side in the bottom of the fuselage is the aerotow release servo. The two white coloured tubes in front of the receiver channel the twin aerials upwards in hopefully the optimum position for good reception. I have now to find a suitable spot for the switch before I locate the battery in a cosy little space in the nose.
Brian. :)

Ye Gods Brian, how did you cope with the trauma of a months dust settlement in the workshop when you got back?

Today I have managed to erect the Skylark in it’s semi- complete state for the first time. It all went together quite nicely and I think it looks smart.
A session on the balancing rig saw me setting up C/G locations at 86mm, 92mm and 96mm back from the leading edge at the centre section. This equate to static margins of 15%, 12.5% and 10% respectively. I first added lead to the nose to get the C/G at 96mm back (10%) and then added two other lumps which will bring the C/G to 92mm (12%) and then 86mm (15%). After first flight I hope to be able to remove these two additional lumps to achieve the trim that I desire.
I still have control surface checks to carry out and some programming on the Tx before the maiden but we are nearly there.
Brian. :) :) :) :) :)
