Michael, what is your distance from the vertical bars on the F711 to the front of the F710B angle. It should be 13 1/32inch, i am not saying mine are correct, but the front of my HS line up perfectly with the F710B.
Regards.
Arie

Default 710B and 710C

Tough to tell because of the angle of view, but it appears to me that the 710B and C are not positioned far enough aft. Perhaps the F-710 bulkhead is bowed forward?

Also, my plans show the distance from the forward edge of the HS rear spar to the aft edge of the HS-710 and HS-714 spice angles to be 12 3/16" - so you are right on with this measurement.

Best regards,

Merrill

Default Angle dimension

Is the angle the correct dimension material?
It looks right but if they made it from the wrong stuff, the flange may be too narrow.
Just a thought.

My thoughts exactly...but I measured the F-710B angle and it's the proper 1" X 1".

I just got off the phone with Van's and They are perplexed why the F-710B angle is too far aft. Everyones curiosity is up at Van's, they are pulling a -7 fuse down to take a closer look and will get back to me.

They also had me set up the stabilizer with better clamps and add the 3/16" spacers under the rear spar. This has brought the distance down to about " too far aft.

Although Van's doesn't know why (yet) everything is off, they said there's a couple fixes. Depending on if I can get an acceptable edge distance on both the F-710B angle and the HS-714 angles, I can split the difference and proceed to drill the stab in place. Otherwise if I can't get the edge distance they want me to drill off the deck and move the F-710B angle around to get things to line up.

Being that this is a QB fuse, I'm not keen on doing that and risking screwing up those AN4 rivets on my dime.

Default Horizontal stabilizer mounting

You are more than welcome to give me a call to discuss this issue if you have not figured it out yet. I'm sure we can work through it together.

Talking Synergy Air Rocks

Ryan Marshall from Synergy Air is the man!

After Ryan suggested I give him a call, I did and he figured out what was wrong in pretty quick order.

So the forward spar of the horizontal stabilizer is biased rearward by a little less the ⅛". This of course doesn't help my problem.

But the big issue was that the F-711C vertical bars were not square to the aft deck. In fact they were leaning aft by a hefty amount. Ryan said he always takes great care when installing the bars to get them perpendicular to the deck before riveting.

Well after a little tweaking, my F-11C bars are now square and the error is down to less than 3/16". I can make that work.

Wow what a head scratcher. Tomorrow the horizontal stabilizer goes on

Just a question, how did you tweak the F711C bars to be perpendicular to the aft deck?

Using a 24" crescent wrench with padded jaws. Slid the jaws down the F-711C vertical bars until near the deck. Using another wrench on the 24" wrench, I carefully straightened the F-711Cs.
