Corbin,

The washer placement on the mounting of the caliper was key to getting it to not hit when we put it together.  Make sure all of the washers are exactly where they were.  I believe there were washers used as spacers under the caliper mount.

That it about all the advice I have on that one without seeing it.

It is so dark up in the wheel well that I couldn't get a good one.  I will take my endoscope camera out there next time and get a photo/video.

Hey guys,

Some of you saw my photos of the dried brake fluid on my brake caliper and now I have another brake related issue I need your experience to help with.  First, I was able to get the caliper all cleaned up and everything looks good so I am going to keep an eye out for small leaks. 

Now my problem is that the anvil (inside part of the brake caliper) is rubbing up against the tire.  No matter how I try and line it up it still rubs the tire just enough to stop it from spinning freely.  I even thought maybe I have too much air in the tire causing it to bulge out too far.  I will double check that in coming days just in case.  I thought I might could get a grinder and grind down the anvil a 1/4 inch or so.....

Any other thoughts?  I am certain the anvil is correctly installed onto the caliper and the bolts have no issues lining up and going in.

Corbin,

I think the 5.00 x 5 tire size is half your trouble. The 4.00 x 5 would be narrower yielding more clearance from sidewall to caliper.

Which size tire do you have installed? I'm showing 4.00-5 on mine.

Thanks David,

 

I will keep at it. Maybe I will add a little reflex to the trailing edge. It is possible to design the elevator so pressure loads are essentially zero when it is not deflected. I can load the GU to see what it does, because it did not require sparrow strainers. It may have required some spring assisted trim, I don’t recall.

 

I am using Javafoil. It is Martin Hepperle’s freeware.  I like it because it is simple and I am simple.

 

Cheers,

Jay

Jay,

 

Nice work. Your modified LS1 elevator would go a long way toward reducing the workload required of the sparrow strainers, but you’d still need something like sparrow strainers to push the TE down for normal ops. The Roncz airfoil’s elevator is intentionally designed with a slight “reflex” on the trailing edge just so that it won’t need sparrow strainers or trim tabs. I suppose that with a little more work you could achieve the same with your modified LS1 elevator. 

 

Keep at it!

 

(BTW, what software is that?)

Hi Bruce,

 

A few years ago, I tried modeling the existing LS1 and only changing the shape of the elevator to try to eliminate the strong asymmetric pressure on the trailing edge (which is the reason you need the sparrow strainer). The reasoning was, that maybe someday, I would build a new set of elevators with the revised shape and leave the sparrow strainer off because it would not be needed. Here is a comparison of the pressure distribution on the the original LS1 for 0,3,and 6 degrees AOA (first graph) and for the same airfoil with the revised elevator (second graph), which would fit in the same slot. Note the difference in pressure on the top/bottom near the trailing edge. The modified version provides slightly lower lift than the original.
