I have both the delrin stops and the tiny angle stops as the plans call out. Sort of a belt and suspenders approach. They both bottom out at the exact same place, so the 7/8" dimensions are correct for the RV-9 wing.
Here is a photo showing both stops hitting the limit. ![]() ![]() The wings have been on the fuselage, and all of the preliminary rigging has been done. If ever the delrin should fail, the other stop will be there. |
I followed thru on this topic; and got a 4 pack of 3/4" dia. wheels @ LOWES aerospace. (and a 'hit & run' dent in the side of my pickup truck:mad:)
The wheels have roller bearing & threaded axles, so I thru drilled .187 and installed them (plus a washer) in place of the spacer. 28 degrees of up travel is where they stop the aileron. That's about mid way between min and max travel. This time, I had a magnet on one of those telescoping handles. :D It seems like I drop the washers and nuts at least a dozen times, so that magnet really sped up the process of picking up the bits and trying again. |

The package label is ![]() You can get them in various lengths - the 1" is ![]() These are 1/2" diameter not 7/8". I don't have the final measurements handy, but after installing these, the aileron travel fell within the Van's guidelines (RV-7). Price for this pkg was $0.92. Dan |
0.5" worked for me
Here's how I did it:

![]() Got me within 1 degree of max travel. Thanks for the help |
Cool idea! I mostly keep an eye on the -3/-4 forums, but I obviously need to expand my perusing.

After over 100 hours they have held up just fine. Full write up on the stops are here: http://www.rvplane.com/?categoryid=4&dayid=556 |
Living in the sticks
This is the point in my build and I would love to get a set of these 7/8" stops from Lowe's but live in "the sticks". Anybody near a Lowe's that can help-a-fella out and I cover the expenses and a beer for your trouble?

AMEN.. It was HARD to peel out the cash because they are a bit pricey but that event is long gone history. I'll still be clutching them in my clammy dead hands when I pass. They are GREAT. :D
