Can anyone please help me! Below is my cake and a sample picture of the shape. bottom was 9'& 10', middle was 7'& 8' and top 5' & 6'. I was thinking maybe my bottom and middle was da problem. I transported in trunk and when I arrived the 2 tops had busted the bottom tier. Do you have to use 3 layers for each section when doing a whimsical / turvy cake. The middle section mid air with nothing supporting it underneath. I probably should have used a smaller bottom for the mid section or a larger top for the bottom section. I'm new to decoarting so please help!
Donyell,
What types of supports did you use? Did I read right that you didn't use any? If so, then that is def. the reason this cake fell. You can never ever ever not use supports, but that is even more important with a Topsy Turvy Cake.
Also, it looks like the cake doesn't have a center of gravity-where the center of each cake lines up perfectly.
Did you have any supports in your cake? If you didn't then that right there is why it fell. You need to have cake boards under each tier and dowels in each tier that has a tier sitting on it. If not, the weight of the top tiers will crush the bottom tier(s).
I've never tried a whimsical cake, but now I'll be sure to use supports.
In reference to supports, of course Sandra Lee would disagree with you alllll about, but that's neither here nor there. 
Wow....no supports? Did you research how to assemble one of thse before taking on such a monumental task? I don't mean that in a crticizing way, but that is just such a delicate setup, it must be researched and practiced. And transporting in the trunk? That part of the car is the worst place to transport any kind of cake! It's the part that bounces and slams around on bumps and wow....ok, lesson learned hopefully. Good luck next time, and remember there are lots of people in here willing to help with any questions you may have in the future! ")
Experience is a cruel teacher.
So true... 
Even with supports the middle cake is too far to the side. In the final product, if you just looked at the base cake boards, they should all line up just like a regular cake.
Also, did you do the cut out method? Looks like you did and that's what I use too. It's a good method. But if you just stacked crooked cakes, that could have been a problem too.
Of course I used wood dowel supports and boards under each tier, but I can agree with koryAk about the middle tier being too far over. This is not my first tiered cake. Most of my cakes travel via my trunk. Normally I would have assembled at hall but because it had tons of dowels and was very stable. I was comfortable transporting in one piece. I guess I was looking for some info on stucture, not method. I know it has to be doweled. I was hoping for a technique or secret you seasoned decorators use. Thanks for responding
Thanks,
Donyell
Here's instructions that I like to use. The diagram really helps to see how each layer sits inside the one below it. http://members.nuvox.net/~zt.proicer/message/saved/TILTEDCAKES.htm
My first TT collapsed before my eyes. I know the reason that mine did, was because I was using a really moist cake, and I tried carving at it too much.
Also, I would recommend using the 3 layers vs. the 2. However, if you are getting the height that you need, then I am sure that is not the problem.
I also don't know what cake you are using, but my next TT will be with the WASC for sure.
