Hi,

I'm brand new to the forums, and relatively new to RC flying. I'm currently building a semi-scale DHC-3 Otter from a kit, so I have the occasional odd question as I make progress.. I don't know very many modelers yet in my area, so I'll ask here...

Here's one - how come hinges on control surfaces get glued and pinned, but control horns are typically a two piece affair, with the horn, and a backing plate that gets bolted together? Why not use bolts on all the hinges? Do horns need it because of the greater shearing load on the control horns?

Thanks,
Scott
