Ahhh the Metric... My first ever glider from 1983, it lasted 10 years and won some 2m club contests before being trashed when the shed it was being stored was damaged in a storm and it became waterlogged and infested with ants... (sigh) I still keep the fuselage and plans in the workshop thinking I'll build another one for the children who are showing an interest in flying. The only problem I had with it was the balanced rudder was a litte flimsy as it was so light and it tended to break level with the top of the fin (just below the balance tab) if it flipped inverted on landing (which I managed to do a few times while learning). I ended up reinforcing the rudder and I added a 1/4" sq spruce block each side of the fin, shaped and positioned to match the tailplane in the neutral position to give more support to the all flying tailplane which tended to wobble as the support tube was only 1/4 - 3/8" long in the orginal design. Apart from these two easily fixed things, it was a fantastic model, it flew well, was well behaved thermalled and sloped really well. I added the optional spoilers and these worked well too, though these days with micro servos, you'd use those in the wings instead of the pull cords we had to use then. From memory there were optional ailerons that could be fitted as well.

The length of the aerial is a function of the wavelength of the signal. Consquently the amount of "shielding" of a carbon prop is not related purely to how much area the disc covers in comparison to the antennae as such, but how big a gap there is between the blades when they rotate and how that compares to the wavelength of the signal. Eg, microwaves are in the order of 1-3cm in length, so a metal screen with holes around the 1cm dia mark will stop most of the signal getting through (which is why the screen in our ovens are around 2-3mm in diameter) Given the size of the aerials, I'd think that a carbon prop wouldn't be an issue.
