.Guys here's a picture of what can happen if you don't secure your fuel caps good. Â This was a rather expensive lesson for me. Â In the future I'm going to attach lanyards to my fuel caps. Â While flying my plastic fuel cap came off and went through my Sensenich wooden prop on my Mark 3 Xtra. Â I was lucky there was a grass strip near by. Â Surprisingly the vibration wasn't too bad. Â Had that chunk departed, it would have caused an unbalanced condition. Â As it was, it just made a loud change in the prop noise. Â

You might want to consider a Warp Drive for your replacement prop. If you had one, you would have discovered you lost the fuel cap at your next re-fueling stop.

That is true, I managed to leave a heavy pair of side cutters on my wing while testing my engine inside the hanger. The cutters hit the ceiling, but didn't hurt the warp.Larry

This must be the season for it.  One of the exhaust spring hooks broke and the pieces of it went through my prop the other day.   Safety wire on the spring held so only the pieces of the hook made the hit.   A couple of flat places in the nickle leading edge were the only damage and I was able to re-shape those pretty well as directed on the Warp Drive website.  I am replacing all the hooks on the front connection.  The rear hooks look ok but all the front ones are corroded pretty badly.I think this is because the exhaust  joint faces that direction and any exhaust leaking around it would hit those and accelerate the corrosion process.  See attached pics of the good and that broken.  Anyway it's something that might be worth checking.  I know I'll pay more attention to that area from now on.

Spring hooks? Broken springs? Damaged props? $15 and an afternoon of work and that problem goes away. Some 5/16" bolts, flat washers, cotter pins, some small compression springs, some large diameter muffler clamps from which you cut off the curvy little ends where the bolts go through and weld those pieces onto your exhaust. During your annual inspection check the bolts, they will probably have wear grooves in them about a 1/16" deep. That's why you start with 5/16". The pictures explain it all - sometimes overkill in this area is a good thing.



Also, notice the size of these 2 pictures: less than 50 kb each. The last several posts on the list of busted props, & trailers for sale have been pictures of 2 megabytes or more, and no "Do not archive" tags.  So much for keeping the list archives at a manageable size...    Not to mention how long large picture files take to download: my computer happily plays graphics intensive online games at nearly 100fps, but it still took a while to get those 2 meg files downloaded. In Windows 7 & 8, all you need to do is right click a .jpg picture file and tell it "resize;" problem solved.

Thanks for the info. I do wish these pictures were a little bigger however. My eyes aren't what they used to be.

Here's what you do: When somebody posts a picture that is enormous, and you have to drag the screen back and forth to read the text, or see all of the picture, I go to the top right of the screen and use that little plus/minus thing in the browser to shrink the page down to where I can see the whole picture at once. Of course, you can't read any of the text, but  - whatever.



The process also works in reverse. You can make the pictures as big as you want, and then the text is really easy to read.

Dragging the OVERSIZED photo to a new folder on your desktop allows quick convenient viewing at a normal size.  Label the new folder â€œTEMPâ€ so that you will know to dump it when you are done.

Or maybe if people would be kind enough to simply resize their picture to "Large" using the default windows right click on their picture before posting it, none of us would be going through all this rigamarole and wrangling.



Not to mention having to drag the browser bar back and forth to read all the unnaturally long lines of text that accompany oversized pictures and run off the sides of the screen. 



But hey - that's just me and my simplistic way of thinking.

I do agree that some pictures are larger than necessary but reducing them too much loses resolution and detail that can be useful for some things.  You can't regain that just by increasing the magnification of the page.  My thought would be to just use some judgement as to the size needed to illustrate what you want.

Since we're off-topic anyway, here is my suggestion: use a free-ware app to resize. Today's cameras produce very high res / large files, so resizing is almost always required before posting. I use Irfanview (search the web) to crop, then resize to 1920 x 1080 pixels, which usually results in file sizes in the 400kB range. Irfanview also allows you toÂ color-correct and even rotate the picture in small steps. The attached photo of my Earthstar eGull project was treated that way.
