Status: offline 		Way back when, Bob Boucher designed the Monterey.... featured in a magazine construction article. It was a super looking plane intended for Speed/Distance events. Given the somewhat lenghty engineering discussion in the article, I'd say the design was well thought out. Which brings me to wonder how it's unique design actually panned-out in practice.

For those familiar with the design, you'll recall that it was a sort of modified spar/D-tube design sans main spars. That is, what served as a spar was only a 3/32" shear web running the length of the wing. The forward 1/3 of the wing was sheeted per conventional D-tube manner. No cap strips were used. The system appears to be absolutely as light as is possible to construct a wooden wing.

So, it gets me to wondering if Its' wings actually lived up to their 16G design limit?????

Status: offline 		I don't remember anyone saying the wing was weak, BUT if you give it to someone who is used to today's sailplanes it would last about 2 seconds on a winch before it broke. The wing made good use of the wood in the wing, but it's wood not CF so you are talking orders of magnitude difference in strength.

The Montery did have a spruce spar on the top with no spar on the bottom only the sheeting. Wood is many times stronger in tension than in compression. I'd have to agree with Soarrich in that this was designed for high start and the old 6 volt winch of the 70's. I haven't flown sailplanes since about "82" but I did attend a local contest just to see what was happening and the speed and power of the newer 12 volt winches just sent chills up may spine.

The Montery's little brother the Malibu did not have any spars. It had only the sheeting and shear webs. After this kit came out AFI modified the design by extending the sheeting behind the D-spar further out towards the tip. I'm using this wing to put together a little electric powered sailplane.

Good luck

Mark
