We have lots hours on lots of the Sensenich Ground Adjust props on many airframes and engine combos and have not had any issues.  I think there are issues when one takes a prop make for a rotax and puts it on a bigger engine that there are issues.  Look at the size of the hub and blade roots on the whirlwind or Sensenich for the lycoming or other legacy engines and you will see they are much beefier than the NR or others.  

I wouldn't give up mine for anything, it's truly that much better in take off. climb and cruise than the old Borer that was the benchmark and go to for MANY years.

Thanks for the effort! Looks like it would be probably 3 5/8 inch long and the rest of the dimensions could be ratio calculated from a scan I have. 

Sorry, couldn’t get to this quicker, some reason the form one let me put pictures up from mine iPhone, but I can take pictures of my five phone and put it on my iPad and send them, damn computer world anyway happy new year everybody fly safe, stay healthy, etc.

Anybody familiar with this outfit, 6 1/2 pounds is great

I agree with the value of the forums.  I was devastated when yahoo was purchased, and the groups there were destroyed.  All of the years of knowledge that had been contributed, were lost. I've spent lots of time going through threads, here, there, and everywhere, trying to find answers before reposting a question that's been asked before.  Sometimes, you have to have the right incantation, or key phrase.. as what you guess isn't what it was posted under before. And if you find something of value... COPY IT.

I'd seen your firewall thread, and most of your kitfox build posts- it was one of the things that really had me going nuts- I had no idea that there were different starters, until I started looking at them a couple of days ago. Now, I know.. That's also why I left the breadcrumb of information in that picture for the next person that comes along. I first modeled the two sides of the lower firewall out of cardboard, and figured the dimensions for the pedals, and brakes, to clear.  I made the inset as per the instructions, and.. it didn't look right.  Motor's in the mount, so do a flat measurement and look at the clearance required for the starter, and it wasn't even close. I have an inset I'm going to go with that is almost the full depth of the well. I'm leery of cutting up a $400 starter unless it's absolutely needed. The passenger side doesn't have brakes, so the inset isn't (?) a major problem.  I've been digging through firewall coverings as well, and ended up ordering a carbon felt welding blanket which I'll fit to the backside of the firewall, and cover with.. something.  It is nice and light.

Thanks for the response, and guidance.

One of the early reports said the engine departed the airframe.  This has proven out to be inaccurate.  Needless to say, loosing a blade will defiantly be a catastrophic situation...

I remember when my friend Dave (built Sputzee the Avid-Kitfox hybrid) was later building a J5 Cub with an O320 on the nose, his research told him that adjustable props and direct drive engines are not a good mix.  He went with a solid Catto on that build.

I bought some a few years ago, and it worked ok for what I was doing with it.  Non structural parts though.  I can't say if it's good or bad other than it did what I needed it to do.  JImChuk

I have looked at the wicks steel that is $.50 foot. It all has a C on the end of the part number, which designates it as being of chinese manufacture. Have you ever worked with it or handled it? Would be interesting to hear opinions of someone that has worked with it or seen it. I remember hearing a number of years ago some less then flattering opinions on it. 

This was a fairly old thread.  But it shows why the forums are so much better than facebook.  An old thread with it's information can be pulled up real easily with a quick search.  As I understand it, those lugs get cut off with no problem.  I had the one of the old style starters on my new Kitfox build and the motor mount is further forward, so I didn't have a issue when I used the old type starter.  Here are pictures of my firewall on the rebuilt Kitfox.  In the one with the engine mounted, you can see the starter and how it fits with the depression in the firewall.  Especially if you zoom in on the picture.  After I was done, I thought that I may have been able to hammer out the depression on the firewall, and not add a second piece.  It would have been nicer if it worked, but stood a chance of ruining the whole firewall if it didn't.  JImChuk

Wicks has some  for way less.  Thicker wall though.  Look at the 3/8" and 7/16".  $.50 a foot for some of it.  JImChuk

I thought the same thing Leni.  If he got knocked out with the prop blade, that would have been all she wrote.  But at the same time, the blade doesn't look like it hit anything very solid either.  Guess they will sort it out.  I don't think there is much worry with the NR props and 912 Rotaxes at least.  I flew behind mine today and all was good.  JImChuk

Just for fun I was thinking I'd take a scan to an embroidery shop and seeing what they would need to do a few. If I remember John had a few left and Steve Winder had gotten them from him. Don't know what happened from there with the remainder or ever where Steve is now...

The 4130 tubing is the one that gets me going. 3/8 inch .035 wall... like seriously?Last I looked it was pushing $10/foot..

damn, seems like an 0320 on a KF is kinda heavy for it.  Shedding a blade inflight could have knocked him out if there was plexiglass and cockpit contents 1/2 mile from the wreckage.  

Kinda like WAY too many cubs, the pilot could have survived the crash, but the fire afterwards gets them.  This one looks and sounds like a single point landing on the nose.

Sad to say the least.

Well drat.  Just found this thread.  I have the 912 uls and am now on my third firewall iteration, fighting those lugs on the starter.

I was wondering whether the lugs were essential to anything hidden inside, and Paul's solution has just made my life a lot easier.  Off with the lugs.  On the bright side, I've gained a lot of practice on sheet metal work. This is not my engine, but the lugs seem to be the same.

I've bought these ones several times for various airplanes.  JImChuk  Suspa C16-10788 Pair Of Gas Prop Lift Support 12.2" Ext. Length Topper Shocks | eBay

just for fun, plug in shipping to 99669.  Bet you really get a shock, no pun intended.

I’ll take a Measurement tonight

The springs also tend to center the rudder in the absence of pilot foot forces. 

Yep! There is one in all its glory! So would that patch be 3 inches tall?

just received a quote from McMasters, UNBELIEVABLY, worlds going to hell in a handbasket

I’ve got memorabilia that goes back to day one

So Back in the mid 90's John Larsen had cloth patches made to promote the avid flyer. Does anyone remember the size of them or by any chance have one in their possession?

That's how I see it.

long time no update...

work, family, house refurbishing and flight lessons are only few excuses why my bird is not flying yet again. Honestly had disillusioning moments during the rebuild. But fortunately finally all the small achieved objectives puzzles together so hopefully there will be a flying plane again someday...

partial success

rebuilt 582 with all new cylinders, pistons, crankshaft,...

new wingtips

reworked fuselage, blasted, painted and smoothened out for Oratex

next put back header tank/fuel lines, wires for trim, ACL and antenna and lots of reaming prior installing all new AN hardware...
