Winch? Which Winch?
From: "Douglas" Subject: [Star45] Winch? Which Winch?
To: Star45@yahoogroups.com

Is the Hitec HS-785HB Sail Winch Servo enough for the star or is the RMG the must have for the star? Is there any other options, better options with regards to a drum servo? Is the drum the best choice? What's your opinion, I'd very much appreciate it?

I have not use an arm winch for years, but one difference I found was that they tend to use more power than the RMG. I usually use about 600 mah in 3 hours of sailing with an RMG. So I run 1340 lipo’s and swap at lunch on a big regatta or not at all on club days. Only 80g for the battery. I usually use more battery out of the TX than the boat.

I also don’t like that the power of an arm winch changes depending of your sheeting. On my M it used to sheet out while reaching on the puffs. With the RMG this doesn’t happen. I have considered the new digital ¼ scale servo’s since they are super fast. Now you can gybe without losing speed.

If you want a cheap drum and have not used an RMG before the Hitech drum winch is a good choice, about $50. But once you sail with an RMG with its quicker speed you wont want to go back. Also you will need a more advanced radio to change the sheeting length as it only turn 3.5 turns, while the RMG has programmable travel.

The Futaba 5801 is an excellent choice for the Star 45, and has one particularly nice feature in the form of a set screw that allows you to dial the travel length right there with the winch installed. It is also considerbly cheaper. The winch retails for $149.00 from www.towerhobbies.com and they have a special right now for a $150 order take off $15.00 so $135.00 and it may even qualify for free shipping. Smoking deal.

Personally, I prefer a swing arm over the drum winches because of reliability. I know several guys that swear that they have never had a drum "spool off" but I am the opposite, I have never had one that did NOT spool off at one point. Just my .02 but I don't know of a swing arm winch that I like for the Star, they are either too big or too small. If I was to pick one, I would say the Ozman or Probar, I think those are still available.

    I got a set of the new 2P spars from SkyShark and tested them in my Legend IQ ultralight that normally uses the 3P spars. This is a nice 8 gram rod. The old 2P was the same diameter as the 3P, 5P and 7P, which made it convenient because it was interchangeable with the same fittings that are used on the other rods. Although it had a pretty good stiffness to weight ratio, it was also a bit fragile for the heavy use and harsh flying that I like to do. I've never used them because I could break them so easily.

    This new 2P is made with a smaller diameter. A concept Erez says that was suggested by David Lord. I believe he used the diameter spec Dave suggested when the new mandrel was selected. Otherwise, it appears to have all the same characteristics of the old rod, except that it is much, much tougher.

    I've been flying with it for a while now and have been doing a lot of ground rolls, tip stabs, coins, cartwheels, and hard snap stalls (basically, I've been trying to break them!). Ground work and hard snapping maneuvers will weaken a rod but so far, this new 2P has held up wonderfully. This one is probably tough enough to accept a set of Power-Tite connectors which help to stiffen up the frames made of light weight spars. At any rate, it has proving to be a very durable performer for me.

    Good Winds, Bert

    Thanks for the great info Bert! How do you think these spars will hold up (in terms of toughness) to other SUL spars like the G-Force?

    Don McCasland at Kites of Boston has a pretty good stock of spars and can order anything that he doesn't have.

    I can provide small numbers of spars for repairs and such. I don't really do retail, however, but am happy to help out if you need something on the field and I have it with me.

    I highly recommend Tom Marvin at Hang-em High Fabrics in Richmond VA. Tom has all sorts of spars and fittings along with Icarex and regular ripstop nylon.

    Another good source of spars is the High Fly Kite Co in New Jersey. Fran Gramkowski has lots of experience with all sorts of kite spars.

Kli-Cons

No more fiddling with set screws, stripped threads, looking for Allen keys. Connect your push-rods in a split second!

Earth magnets grip each section of the push-rod together to withstand the most rigorous workout.

Each KLI-Cons™ magnet set comes with a special threaded brass connector, which you solder to the end of your push-rod.
Kli-Cons

The magnets are threaded onto the new pushrod end, fine tuning by threading up or down. Approximately ½” adjustment is possible.

KLI-Cons™ come in pairs, north and south magnets. Place in different directions to ensure you do not connect the wrong push rod; the wrong magnet will repel the rod.

How to Make a Medicine Bottle Air Horn

from wikiHow - The How to Manual That You Can Edit

An air horn brought from the store will only last as long as the compressed air inside the can does, but with a few household items, you can easily make your own air horn that will last quite a long time!

Steps

1. Using a heated screwdriver will make it easier.Poke a hole in the cap, side, and bottom of the medicine bottle. Size does not matter, except for the hole on the bottom, which should be large enough for a drinking straw to fit snugly into.
   
2. Take the cap off the bottle. Cut a piece of a balloon and stretch it over the top of the bottle. Secure the balloon with a rubber band. Replace the cap on the bottle.
   
3. Cut another piece of a balloon and stretch it over the bottom of the bottle. Secure it with a rubber band.
   
4. Poke the straw through the hole on the bottom. It might be helpful to first poke a hole in the balloon.
   
5. To use, blow into the hole on the side.

Tips

• Use a heated screwdriver to make poking holes in the bottle easier.
  
• If it's not working, try moving the straw up and down.
  
• The straw should be longer than the bottle itself.
  
• The larger the straw (in circumference), the louder the sound will be.
  
• Making the hole on the side larger will make it less of a strain on your cheeks to blow into it.
  

Warnings

• Do not use this air horn near anyone's ears; it could cause hearing damage.
  
• If using a heated screwdriver, exert caution not to burn yourself or to breathe in the fumes of the plastic.
  
• Exercise appropriate caution when using edged tools such as scissors.
  

Things You'll Need

• Medicine bottle
  
• Scissors
  
• Balloons
  
• Drinking straw
  
• Rubber bands
