what do you guys think of those pinned type hinges?

like these:

Your picture is not showing up on my screen, but I'm assuming that you're talking about Robart hinges. I use them on most larger planes, but on 40 - 60 size I use CA hinges. I have even used CA hinges on 180 size planes with no problem. The big trick with CA hinges is proper installation.

Here are a few tips:

I fly a few 27% models and prefer the radio south brand ca hinge...they are composed of mylar sandwiched inbetween the typical ca wick material. Check them out at your LHD or on Towers website. I always seem to get a lot less hinge gap with the ca hinges vs the robarts...but maybe it's just me! Anyway the radio south hinges are about the strongest ca type hinge I've found and I have complete confidence in them.....

the picture i posted is of the robart hinges, ive seen only larger models with these kind of hinges, everything smaller ive seen always uses the plastic(mylar) ca hinges

Robart also makes small hinges. Attached picture is my CG Electra, with the smallest of the Robart hinges. Second picture is a closeup of one hinge as installed.
