Hey Jack,

               You gave me an idea on those Dog tie downs...



 I think I'll cut it like you did....then heat it and make a loop and weld it.



 I'll have to screw'em down with a straight bar....but it should make'm



lighter and smaller.... Thanks !

FWIW, I disagree with your 1-d) -- I suggest you put the rope through  

the ring AND around  the strut -- I saw a 172 that went over on its  

back when the steel-ring weld broke.

And you should not hold the stick back with the seatbelt -- this puts  

the elevators UP and tailwinds will try to raise the tail.

Much better to secure the stick FORWARD, putting the elevators down  

and causing the wind-forces to hold the tail firmly on the ground.

If the stick is back and the tailrope breaks she can be on her nose  

quickly.

I always used tie-down screws, like big heavy dog tethers, for my  

170. Carried a hardwood stick to screw them  in with -- until a  

grabbed it and ran off! Short pieces of rebar work OK  (2 for each  

wing)  but are heavy too

 On my Cessna Skywagon, I use two stakes, plain straight rods with  

 sharpened

 ends, about 18' long, at each location. They are pounded into the  

 ground so

 they cross - there's a bracket that holds them in that position.  

 Simple and

 works a charm.



 The stakes are titanium; it's the best combination of strength and

 lightness.



 The aluminum bracket has a hole for the rope to the wing.



 Here's what I've learned at Boulder Airport, watching airplanes get  

 blown

 over in our high winds.



 These things  not what most people do. Most people do it wrong.



 1. Rope stretch lets the airplane bounce around, and the dynamic  

 overloads

 break the airplane loose. Here's how to avoid that:



 a) Make the ropes out of polyester. One of the marine ropes like  

 Sta-Set is

 excellent. Do not use nylon or polypropylene ropes or straps. It's too

 stretchy. If possible, double up on the ropes.



 b) Tie the ropes tight! I mean so tight that when you're pulling on  

 them,

 the airplane squeaks.



 c) Tie the wing tiedowns first, then pull the plane back with the  

 tail one.

 That makes the ropes tighter.



 d) Don't tie the ropes over the strut - tie them so that they can't  

 possibly

 slip down and pull the strut out of column.



 2. Orientation is important. If you can predict where the wind will  

 come

 from, place the plane so that it's a quartering headwind. Sideways  

 is okay.

 Head into the wind is bad, because that way the wing will work, and  

 the

 possibility of dynamic overloads is high. Don't have the wind  

 coming from

 behind at all, because of the potential for control surface damage.



 Got a question now - how do y'all tie the ropes to the wings? On my

 Firestar, there's no tiedown points.



 Thanks!

That is what I did. Works just fine. And you can nestle them all 

together, which takes up less space.

Hey Guys,

               Just so happens I had to take my dog to Petco for her shots...



 I looked around and found the screws....they had two sizes...18" & 16"



  I bought 3 of the 18" ones at only $4.49 ea....



   I'm trying to get things ready for my first cross country....(300 miles aprox)



I want to fly to Baraboo WI to check out the Tailwind Fly-in ....



I'll start building mine soon, So I'm hunting for more info & Pictures...



Also I was promised a ride in one too...



 Hey Hauck, any "tips" on tools to bring....I'm thinkin the basics

Mike:



What ever you think you may need to keep your bird in the air long 

enough to get you there and home again.



Basically, I use an old Rotax tool kit, the one that is plastic and 

rolls up.  I have added a few wrenches, pliers, allen wrenches, etc.



Duct tape, safety wire, nylon tie wraps, are always handy for 

temporary repairs.



With a two stroke, definitely a socket and rachet to pull plugs and 

something to gap them with.



As you gain experience flying your Kolb, you will find out what it is 

going to take to keep you going.

The answer to that question is no! I have both items and they would not 

stick together.

Thanks for the thoughtful comments on my tiedown suggestions.



I'll comment on some of them now. Before I do, I want to reiterate the most

important point - don't permit any slack or any stretch in the tiedowns,

because it's aircraft motion in strong winds that destroys airplanes.



1. John Hauck suggested that I "Use the bottom tang on the upper lift strut

tang to weld a sturdy ring" on my Firestar. Mine already has a tiedown ring

as an eyebolt for one of the strut through-bolts. I was unsure if that was

adequate and so far, haven't used it (I've kept the plane out of the wind,

actually).



2. TheWanderingWench asked where she could get similar tiedown hardware and

what the bracket was. The bracket is a piece of round aluminum bar, about

two and a half inches in diameter and about an inch thick. There are two

perpendicular diametrical holes for the stakes, offset so the stakes don't

touch, and a hole parallel to the axis but offset so it'll clear the stakes,

for the rope. The stakes are home made, with the titanium purchased from

Titanium and Alloys. I don't have any contact information now for them.



3. George T. Alexander, Jr. hoped that I meant that the stakes were about 18

inches long, rather than 18 feet long, as I'd written. Yes, George, they are

indeed the shorter length, thanks for checking.



4. Jim Baker suggested: "Why not just replace the lift strut pin with an

AN44 or AN45 eye bolt? Same tensile strength. Carabiner or other similar

attachment can be used to connect to the eye hole....." My Firestar has

something like that but with a big hefty welded ring in each. I don't know

where the builder got them.



5. Russ Kinne reminded me to "put the rope through  the ring AND around  the

strut...." Russ, I do this. Honestly! I just forgot to mention it. But I do

it for exactly the reasons you mention. I've noticed that Cessna tiedown

rings can take more load than Piper ones, though, at least as evidenced by

airplanes flipped over.



6. However, Russ also recommended that the elevator be held forward to keep

the tail down in tailwinds. It doesn't seem to matter much, at least with

production general aviation planes, as long as the controls are locked. For

the Firestar, it's probably good advice, because it's best to keep the plane

from ever moving during a windstorm, and the horizontal tail's stronger for

a down load than an up load.



Thanks again for the great comments!

I saw a home made version of the claw made with 3/16"stainless steel air

craft cable. Had a center ring with three 1 foot runners with collars with

rings weld to them. Works on same principal as the claw pull up on the

center just puts the angle driven rods in a bind.
