Question
Topaz 1st Generation airfoil

I've got a Topaz with a badly warped center section and I want to bag a replacement.Does anybody know for 100% sure what airfoil was used ?? I've seen AG35 and MH 32.
This is 1st gen with one long spoiler
Thanks

I didn't know they sold a vacuum bagged wing.

That said, I would think that the vacuum bagged wing would be the MH32 , and the built up wing would be the Drela foils... Otherwise I would think Mark would have vacuum bagged the Bubble Dancer like he did the Supra.

Unless by bag, you mean acquire.

In which case, nevermind.

I think by bag, he meant that he would bag a foam cored center panel for his.

With that said, I have a first generation Topaz, and it has a bit of undercamber to it, I would say more likely a drela foil. Certainly not an MH-32

Thanks,I was leaning toward the AG35.
I'm bagging a center section because a replacement "open bay" center section is unobtainable

The best thing is to use the current center panel to make templates. I have found that on some of these planes the airfoil is not close to what they say it is. They seem to use the AG series as marketing and not what is really there. Or print a AG35 at that chord and compare.

While setting up for some repairs on mine I found an old reference sheet that specified AG25. It had a bit of undercamber and matched the center section pretty well. Mine is the full house version.

What I couldn't find is the trailing edge settings for this airfoil. What have you guys done for that?

Thank you,

Tim
