Hi Malcom!

The rudder former and the mould-line were the two reasons, why we decided not to cut the speedbrakes. I would probably cut a square opening in the former, but leave some wood on the inside. Then double it with a piece of fiberglass-sheet on each side. A couple of carbon-rovings between the wood and the fiberglass will give you lots of strength...

The lighting system is made by a german company. As I think a very sophisticated system. The lights are Luxeon Emitters. They are driven by an electronic-board which has connectors for each light. It is good for a 4.8V battery. There are two leads for controlling the different features. By programming you can decide to use either one or two channels and you can set the switch-points. For example: I will y-lead the main function to the throttle channel and set positionlights and ACLs htat they are switched just by putting the throttle trim from min to max. So every time I start the engine the lights turn on. The landing-lights will be y-ead to the flaps and set to minimum flap. No problem to fly with a minimum amount of flap if you like to tur on the lights.

I have the three position lights, two red ACLs (bottom and top), a big landinglight in the nose and two small ones in the wings. The ones in the wings are angled at some 35-45° like on the fullsize. I will take some pics of the lighting-system later and post them here.

Best regards,

David
