Just displaying how I built the spoilers in. The servo's are Dymond D60. The hinge is clear tape. The spoilers are each kept down using 3 pairs of tiny 2mm cubed neodymium magnets. The servo cable duct is blocked using silicone sealer so that normal pressure air doesn't leak through to the low pressure top surface and blow the spoilers open in flight. Photos and info in RCgroups thread 1401815.
Nice! Thanks for showing this....
