I am a high school physics teacher in need of some plans for a 1/6 scale Cessna 172. My students will be using it to understand forces, fluid dynamics and electrical systems. I would appreciate anything I can use to give them a better general idea of what they are building.

1/6 scale is 73" W/S. There are a few larger plans on Outerzone. One is 72" https://outerzone.co.uk/plan_details.asp?ID=1799
Others are mostly in the 50 to 54" W/S range but could be blown up to that size.

If you don't already fly RC, I suggest that you're going to find out that a 73" wingspan Cessna is BIG.  Even if you do fly RC, I suspect you'll find that while it may be small lined up next to a bunch of 1/4-scale Cessnas, inside a classroom it'll get much bigger.  Before you commit to having one in your classroom (and trying to defend it from the janatorial staff), I suggest that you mock one up from insulating foam from Home Depot.  Put it on a lab bench and try to walk around it; maybe get some volunteers to gather around it to see how easy (or hard) it is to get a group milling around such a big model without bumping it.

Based on my experience teaching college age and older adults, I'd suggest something around four or four and a half feet (i.e. that 50-54" wingspan that PB_guy mentions).  Maybe even three feet.  That should be visible from the back of the room during lectures, and much less prone to being tripped over.

Guillows makes a nice 1"=1' (1/12th) C-172 that can be found online, at "sale" pricing...    (kit #802)
