Is the stab flat or airfoiled?

live hinging would be great. to be honest im not sure why HET didnt do that. beeing fully molded, live hinging would have been WAY stronger, and way lighter, and would have made the process much faster as you wouldnt have had to mold and of the control surfaces.

I suggested this a few pages ago. You already have the right sized plug. You will maintain the proven het shape & not change the flight characteristics.
Do that & I'll definitely buy one

You might want to see if HET are going to do something first before you invest alot of time and materials into this, could be like the Sapac intake ducts where they did their own in glass soon after you finished yours.

Good point.

I was going to add a snide remark about the length of time HET has already had to correct the problem, but that would be counter productive.

I`d just like to hear HET say that they understand there is a problem and that they plan to address it. So far, all I`ve seen is them letting Vic speak for them, and he`s been saying that there isn`t a problem, if I understand him correctly.

I know you are trying to help out Rodger, the suggestion is only to protect you!
I emailed HET and asked about the situation with the assembly, so far no reply, will email Tony again today about it.

Yep, that was the first thing I thought of when I first saw this thread. Should have had live hinging with the flaps being bottom hinged and ailerons and elevator top hinged.

Lee or anybody, is there a drawing with dimentions around for the elevator?
I have an idea for an ele made from sparse framework and fliteskin utilizing live hinge that would take way less time rather than molding , bagging etc.
Lee, the ones I've gazed at are made flat like from 3/8 or 1/4 sheet and shaped

Wow! great work Brent. just getting caught up from some traveling. I need to get with the team on the elevator debrief.
