RE: tape as hindges
I agree with RCKen. I wouldn't use regular tape unless the plane was very small and electric. [link=http://airfieldmodels.com/information_source/how_to_articles_for_model_builders/construction/film_hinges/index.htm]Monokote hinges[/link] are easy to make and pretty reliable, but I wouldn't use them on something that needed to be very precise.
