[RCSE] Servo trays and Icare site
Good day all. I'm looking for sources of servo trays. The round ones with a cover and possibly a fairing for the push rod. Rectangular may work also. Such as Robbe or Graupner. URL's would be great. Also, any idea what's up with the Icare site. I can't get it to work. Lynn in Anacortes WA. RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Servo trays and RDS site
Michaelis, in fact, has no employees and never did. RDS was a labor of love and a gift to the modeling fraternity involving zero compensation on the sale of the Kimbrough Products injection molded couplers that can be used to install the system. When, in an RDS installation, the servo is installed through an opening in the bottom skin, the removed skin becomes a cover to tape back .No horn or rod is used, so there is nothing sticking out beyond the skin that needs covering. Super neat and effective! Most moldie manufacturers have defeated the use of the RDS, for flaps anyway, by making wings with servo wells oriented at 90 degrees to the hingeline, instead of the 45 degrees needed. Pity to still see stuff hanging out and covers with bulges on them when it is all so unecessary. - Original Message - From: Kevin Sheen [EMAIL PROTECTED] To: Soaring [EMAIL PROTECTED] Sent: Monday, November 11, 2002 12:41 PM Subject: Re: [RCSE] Servo trays and RDS site Covers?!?

[RCSE] Digital 'thumb' servos
Gordy, What's your source for this? I would be interested in reading this study. I imagine the researchers, like myself, were/became interested in the compensatory mechanisms for people over forty who perform critical tasks like surgery, etc. Funny you mentioned that! I was just watching PBS where an old Doc did neural surgery with his thumbs! :-) Do this test, as in like when we fly our sailplanes... a test I have done almost everywhere I have stopped on the road flying. Without looking try to move your thumb, less than an 1/8".. have someone watch your thumb while you do it. Then try to do it while watching and concentrating on moving your thumb less than 1/8". While its 'possible' in reality it isn't even close to probable while we are flying. Certainly someone can do it, and nearly the same place on purpose twice, but most of us have hung from too many branches, hit our selves with too many hammers, pulled on too many wrenches... by the time we are 40+ And in the end when it comes to controlling model sailplanes, it doesn't make a difference. 1/8" is not much, but in that 1/8" there are a few hundred potential servo movement section positions. Of course when you do the test you will try to move your thumb side to side, but try doing the elevator movement where you get to employ more than one joint :-) Frankly if 1/8" movement were enough to matter we wouldn't have sticks at all, just trim tabs :-) Thanks for the comment, and hope your doctor uses more than his thumbs! I'll be thumbing it in Nashville this week with that amazing little plane called the MOTH! Ever tried one? There was an excellent review in RCSD magazine a few issues back by a cool guy in TN. For a foamy wing, its amazing how well it DS's and thermals too. A 60" version would be great since after 40 we can't see anything under 59":-) Gordy

[RCSE] Photos of Wood Crafters 2002 fianlly up
I had to wait until the magazines covering the Wood Crafters 2002 event got their articles published and distributed. RCM, Dec. issue just out and Model Aviation, November issue both carried coverage and is very much appreciated. I offer a slide show and an album, both links are on the first page of my web site. I recommend viewing the album, it has a great deal more text/information and has about 50 photos. The slide show is a large time consuming down load, however, you can adjust the speed of the show once downloaded.Go to http://www.skybench.com For those not aware, Wood Crafters is an annual get together of pilots flying woody sailplanes and electrics ONLY. This event is a fun fly or competition or both, it is the pilots choice and restricted to one entrant per frequency, although we have inniated our Team Entry system with about five or six teams entered already. It is the premier event to fly your woody sailplane. We have folks coming from Fl, Tx, MN, WS, IL, PA, IN, OH, MI, TN, MA, NY, VA, MD. I can hardly wait, nothing but fun at WC 2003. This years competition events are listed in the WC 2002 album, they are different than AMA rules for the most part and designed to be fun. Notably, Don Harris won the Longest Single Flight with a one hour and 22 minute flight that was actually terminated due to the event coming to a close. The comp. events do not have size or date of kit restrictions, so you can fly anything you want to as long as it is a woody (glass fuses are permitted). RES will have two size classes, up to 100 and over 100. An official date has not been set for WC 2003, but it will be three days instead of two and entry will be on a single day entry basis, meaning you can enter one, two or all three days. We had a few folks fly on Saturday and not able to fly on Sunday, had I been set up on a daily basis, more guys would have been able to fly. email for more info or to be put on the wait list. As soon as AMA gives me the official go ahead I'll start cranking on the official entry list.

Re: [RCSE] If wax or PVA alone is fine, why both ?
On 11/11/02 7:42 AM, yclui_hk [EMAIL PROTECTED] wrote: Thanks for all the useful advices to my question about the incompatibility between PVA and wax in another thread. You guys are really nice. It appears that I just need to buy the right wax to solve the problem. There is in fact another question in my mind - why use both at the same time ? After playing around with wax and PVA for a while, I came to the following understanding about the characteristics of these two mold release materials : PVA : 1) Unaffected by polyester resin. PVA has been my only choice when making polyester molds using vacuum-formed ABS cowlings or PVC canopies as plugs. PVA protects these plugs from being attacked by polyester resin but wax doesn't . 2) Resin ( epoxy or polyester ) sticks to PVA extremely well. To make things simple, I use the same resin for making gel coats and laminating. May be it's due to the low viscocity of the resin, it tends to bead up on waxed surfaces but not on PVA. Wax : 1) Finish much better than that achieved by PVA. Hi All, As a modelmaker I have a bit of experience using wax and PVA as a mold release. It is with out a doubt possible to have a part release from the mold using only wax, PVA is added insurance. PVA can be beneficial to act as a barrier between your waxed pattern and casting material. This is good for silicone rubber molds because it is very sensitive to contaminants and PVA can seal them out. PVA can be thinned with water or Methyl alcohol for spraying, and if you have the equipment spraying is nicer than brushing. By spraying it on you should be able to use it over any wax. The key is to start with very very lite coats. Thermals, Don Vetter 2) Applicable on unpolished surface. Using PVA on such surfaces almost gaurantee mold sticking . 3) Allows multiple mold releases but PVA is one-off. Is my understanding correct and complete ? It seems to me that the characteristics of PVA and wax complement each other. Is that the reason why experts always recommend using both at the same time ?

[RCSE] Re: Why use PVA???
Rick Its a belt and braces attitude that is used to ensure release, if you have ever had a part or worse still, your plug stick in your mould you may understand this reasoning. As and release agent, wax or pva is essentialy a fragile film on the mould surface, it is easy to damage during a layup so if we use 2 layers of mould release we have a better chance. Also pva can help to hide imperfections in the mould surface, tends to release with the part, offering a protective layer while we trim the flash off the finished part and you can easily spray most paints both over pva in the mould, as a gel coat, and over the part after moulding as there should be no wax contamination on the surface as it was sealed off by the pva. I would never hesitate not to use pva in most cases. Its got too much going for it!

I'm curious? When and why should PVA be used. I've always had great results using wax alone on the couple of fuse and canopy molds that I've made. A bunch (10-12) of initial coats of the wax before the first layup and then a light coat of wax before each use. I've know others that have had sticking problems but the parts I've laid up have literally popped out of the molds with a slight twisting of the mold to free the part.

It doesn't work Hi Your problem is a common one that most have fallen into, and that is that the wax you are using is formulated with silicone for use in production environments where they can't wait for PVA to dry. You will need to strip the wax off your mould and then re-apply an non silicone wax from your local fibreglass supplies store. The should be able to guide you to the correct wax, its their job. Just tell them what you need to use it for. I use several different waxes but my favourites would be Ceara J-1(a paste that is easy to apply and buff) and T R 108 (a wax that is more durable but harder to remove). Note also that PVA quality varies a lot, with some that dont go on very well unless sprayed. My current favorite is is called Partall Coverall film. Hope this helps.
