Hi Mick,
I built the Glencoe Sycamore a few years back, got it off EBay, and I'd be happy to give you my observations.
The rivets are way oversize, which I sanded off and scribed new ones. The big chin bubble fit well and didn't have the expected distortion, but I replaced the rest of the transparencies. The "too thick" steps were replaced by shaped wire, and the interior was dressed up by scratchbuilding. (kit has basic interior). The main struts are strong and to scale, although the front one can use some stretched spru activators. The wheels/tires are to scale. Now my favorite assembly: The Rotorhead... which is suprisingly detailed (multible piece assembly) in light of the other "in-general" parts mentioned. (the rotorhead REALLY sets-off the display)
Study reference photos.
All in all, it dresses up real nice with a little work, and makes a fine display.
Take care,
Frank
