Elevator travel

[awmuhs]

I believe that the plans call for an elevator up angle of 30 degrees and a down angle of 25.

I have 25 down. But the elevator horns hit the stop at 29 drgrees up. I am using what I believe to be an accurate electronic level.

With the discussion I have seen on a 10 having forward CG with a single pilot and running out of trim at slow speeds I am wondering if I should be concerned.

Anyone have a similar experience?

Hi,

I had the same issue and cross referenced with Vans.

I had 29.5 up and 24 down. When I quizzed Vans they stipulated that this was the max recommended throws. So at 29 you should be fine.

I believe from other discussions the minimums are 25 and 20. So well within tolerance.

The mins and maxes are specified in the small "other" manual that Vans provided with the kit. I'm not home, so unable to give you the exact numbers.

I have just done his. The required throws are 20-25 down and 25-30 up as specified in the "Flight Test" section of the manual. If you are concerned, you are permitted to file the stops to get the throws you require.

Running out of trim is not the same thing as running out of UP elevator.........

Does anyone happen to have a copy of the RV-10 Test Flight section from the manual that shows the acceptable elevator range of 20-25 down and 25-30 up? I searched the electronic and paper manual to no avail.

I am concerned my DAR will have concerns that my elevator travel is 24 degrees down and 29.5 degrees up (limited due to Tosten stick grip).

Elevator 0 degrees is in trail with the horizontal stabilizer, then measure up and down from there.

As well he should. Controls should always go stop to stop. If your grip is hitting the panel that needs to be fixed.
Back to the OP: I can trim for any configuration at 65 kias or more, but in the flare, at forward cg, full flaps, it cannot be completely trimmed, and it’s a pretty good pull to get the stick full aft, and while the pitch attitude is adequate, I personally wish it was a bit nose-higher. OTOH if it was trimable in the flare, a go around would likely need a lot of forward stick pressure, so I think it’s a good compromise. In theory I could approach with less nose up trim, and trade an even higher stick force for a slightly increased elevator force; I haven’t tested this.

Here's a screen shot of that section. If I remember right, it was part of the finish kit instructions????

Randy, Thank you that is exactly what I was hoping someone would post.

FYI, Tosten Is starting to make a grip installation bushing that angles the stick back towards the pilot a bit to help with the clearance at the panel. It’s not up on the website yet but you might contact Kevin to see if they are available.
