[RCSE] Radiation patterns
then if you lose sight of the plane you could turn the antenna perpendicular in order to regain control. Urban legend perhaps... No, not an urban legend. The standard telescoping antenna radiates it's signal essentially perpendicular to it's length. Pointing the antenna at the model is just about the worst orientation. Holding the transmitter above your head with the antenna pointing straight up maximizes the signal strength to your plane. It does this because it's is the best antenna orientation and because you are raising the antenna higher above the ground. No, it's typically not a significant benefit. Coil antennas, such as rubber ducks, are the opposite. They radiate their signal directly in line with their length. Thus, for maximum signal, you do want to point the duck at your plane. Once again though it's usually not significant if your equipment is functioning properly. Bill Swingle [EMAIL PROTECTED] Pleasanton, CA RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Hitec85BB servos
I'm curious to know how you (he) are able to determine that the 85's weren't up to the task? Is it that you saw better launches after switching to a bigger servo or was there something else? -Ben [EMAIL PROTECTED] wrote: Jerry, I use the 85's on my 2M on the ailerons and 85MGs for the flaps with good results so far. One of our group flys a Hera and the 85MGs he used on the flaps don't seem to be up to the task for high speed flap deployment. Wing deep permitting you may want to use HS225MGs for the flaps if you are flying a 3M or larger ship. The HS85BBs should be fine for the Ailerons. If your plane is 2M floater you could use HS81s.

[RCSE] Need a Cobra wing!
Hi all, Well, its a sad tale, but due to unfortunate circumstances last weekend, I'm in need of a RIGHT wing for my Cobra. If anybody has one from a crashed plane, or otherwise, I'd be interested in buying it. Thanks, Lenny Keer RMSA, Colorado RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Hinge tape application.
Thanks to you all! Talk about instant gratification. With this info, I should be able to get started. Thanks. From: "Harley Michaelis" [EMAIL PROTECTED] To: "Sam Cardinal" [EMAIL PROTECTED] Subject: Re: [RCSE] Hinge tape application. Date: Tue, 30 May 2000 10:38:23 -0700 Hi Sam. . . be sure all surfaces are free of lint and dust. Apply bits of masking tape to space the surface from the wing as you want it. Cut a strip of the tape a couple of inches longer than needed and fold the ends over to grab. It helps to have someone work with you to hold one end while you hold the other. Stick the tape at one end of the surface and align the strip along the hingeline, but keep the strip from contacting the surface. Slowly and progressively press the strip in contact, working out bubbles as you go along. Remove the masking tape bits as you go. Make pinholes where a bubble is trapped. With sharp blade, cut excess off at the ends. Note that tape tends to lift away as a surface moves. A fix is to first apply some Z hinges at ends and center of the surfaces, trim the ends and then apply the tape over them. This prevents the surface from moving up and down and lifting away the tape. I like making my Z hinges from the tape material. If you need info on that ask and I will try to locate a file I made up that explains how to make them and keep them free of fingerprints as they are applied.

[RCSE] Soaring in South Texas.....news and info!
1. Over the Memorial Day weekend I flew the slope sites in Corpus Christi. They are great! Both the Macaw and Zagi-400 wings had a great time on the bluffs flying with the seagulls. If you are in the Corpus Christi area, then check out the slopes. The directions to the slopes can be found in the slope site directory at http://www.geocities.com/j_m_kovacs 2. Also over the Memorial Day Weekend, the Houston Hawks Soaring Club AMA #1698 got together. Few pilots showed up because of the holiday, but it was chance for us to talk about what needs to be done for club. The Houston Hawks webpage is coming along at http://www.geocities.com/j_m_kovacs/hawks We are hoping that the club will grow and then we can have a triangle of contests with the Dallas and San Antonio clubs. 3. There were over 10 submissions to the slope site directory. I hope that more are coming! = ADD YOUR FAVORITE SLOPE SITE TO THE GLOBAL SLOPE SITE DIRECTORY AT HTTP://WWW.GEOCITIES.COM/J_M_KOVACS SINK NOT. LIFT or LIFT NOT. THERE IS NO SINK.

[RCSE] Together they die - The Loss of the French Connection
If you're going to die in your plane there are worse ways ... Art Scholl once started to roll his Pitts at low altitude while travelling from one point to another on his busy aerobatic display shedule. The problem was that he was at such a high altitude, even if the was just a few hundred feet off the ground that the plane didn't make it - no Pitts ever will, so he crashed into the ground with an almighty bang - luckily there was no fire. People nearby rushed to help him out of the smouldering wreck, but they hesitated for a while as they heard the terrible curses emitting from the wreckage: 'You idiot, you moron, why did you suddenly forget all about density altitude? Why, why, why? You weren't 600 ft above sea level, you were over 6,000 ft over sea level!' He didn't break anything that day, except his pride, his means of income, and his reputation as an infalliable pilot. Maybe the French Connection had a similar mental lapse? We'll never know ...

[RCSE] Hitec 555 Rx/Airtronics RD6k question
Hi Gang, I hate asking stupid questions I have a RD6000 and this weekend I bought a Hitec 555 Rx with a crystal to match. My problem is the 555 is not responding. I'm wondering what I am doing wrong. Could I have the wrong crystal? Tx is channel 30 and the crystal is 30. TIA, Jon RCSE-List facilities provided by Model Airplane News.

[RCSE] HLG/Aileron Differential
I've just completed the first flights on a home brewed HLG with flaperons. Initial flight testing looked promising, but I've got one problem/question area. The turning ability/response with the flaperons is good, up until a point. After that point has been reached, you can "feel" in the sticks that if you push it much further, nasty things are going to happen. It feels as if a tip stall is right around the corner. I know there is much trimming left to do in terms of CG position and control throws. If anything, at this point the ship is nose heavy. My question is with flpaerons, what amount of differential would be a good starting point? On a ship with conventional ailerons, 2 to 1 has always been a good starting point for me, but with flaperons, I'm not so sure.

Re: [RCSE] Hitec 555 Rx/Airtronics RD6k question
The RD6000 is shift selectable, no? Make sure that the Tx and Rx are in the same "direction". Could one be FM and the other PCM? Make sure they speak the same "dialect".

[RCSE] servo mounting
Greetings! I am getting ready to mount some servos in a foam wing. I've never done that before. So I locate the place to cut the holes, very carefully cut wing skin and foam out so that the servo has a nice snug fit and is a hair deeper than the surface. What holds the servo in place, simply the friction of the fit? Does anyone have a clever way of rigidly fastening them in that also allows for fairly easy removal in case a servo repair is needed? Note that I am not keen on cutting holes any larger than is absolutely necessary in the wing. I'm trying to keep things as light as possible. All ideas welcome. Thanks, Bill -- In theory, there is no difference between theory and practice, but in practice there is. Anon. Bill Johns Pullman, Washington RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] What's the word on Patton foamies?
Tony, I have seen the Patton Spitfire fly but it did not work all that well. Now before making judgement on the plane I think it was a building problem ie incidence or something not the planes fault. Could also have been since Gordy was at the sticks. :) I have one of the P63 King Cobras from Patton and it is a real rock and roll machine that looks like it would be quite fun on the end of a big bungy. My P63 flew great right off the board. Only change I made was to turn down the ailerons on dual rates for racing and left them alone for combat. The kit is a quite an easy build, this from a guy who was building just his second foamie. See Ya, Pat McCleave Wichita, KS RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Radiation patterns
This is not totally correct. The shorter mached Ant. like a rubber duck does have its max radiate signal down its lenght, but not striate off its end. The short Ant. radiation pattern, has more power radiated at a higher angle, and less striate off it side. The ratiation pattern off a vert. Ant. looks like a donut. With a ture 1/4 wave Ant. this donut pattern looks more flat and pushed out the sides. As you shorten the Ant. and it's still electrically mached to 1/4 wavelength. The Ant. pattern looks like it's being squeezed in on the side, so this push the pattern more up in the air, a round the Ant. This could give you more radiation off the upper end (45 to 60 degs. angle up from the sides of the Tx). But striate off the end of the Ant. there is still a hole with very very low radiation. If you had a singal strenght meter and could run it in a radius from the ground (side) of the Ant. to striate over head (off the end) of a vert. Ant.. With you long Ant. on your Tx you will get higher reading off the side and the readings will drop off fast as you start going over 45 degs. up from the side. And very very low off the end (top) of the Ant. With the Rubber Duck you will start off with lower reading off the side but as you go up to 45 degs. and up to around 60 degs. you will have higher readings than with you long Tx Ant.. But you will find that as you get over the end (top) of the Ant. it will still be very low. With a very very short Rubber Duck Ant. you could start to get a radiation pattern that would look like a ball. But the radiation efficient is very low, have lower range. The Tx Ants. are a good compromise for the way we use the Radio's. That's not making the radiation patterns so tight to make the pattern too directional, so we have to make sure that we keep your Plane off the side of the Tx Ant.. HowardKA7YWO SLC, UT.
