Status: offline 		Is it really necessary to have any kind of launch system other than an arm for sailplanes. Reason I asked is because I would rather not spend the money on a high start if it can be avoided. I live next to a large feild which is right below a hill of about 700 feet. Could I launch the glider of the side of the hill. I would guess that there is enouph wind for light slope gliding but I was more intrested in sailing. I would like to try gliding for the days that I don't want to drive to the R/C club, And I live within 200 feet of my. Here is a picture of my proposed flyng site using google earth, will it work for gliding.

Status: offline 		Well... High starts arent cheap, but do you want to hike to the top of that hill every time you want to fly? If you can drive, I'd say its a no-brainer, go for it.

If its steep enough and the wind hits it corrrectly, slope soaring is a blast. You can sky out to the limits of your vision when the conditions permit, then fly away from the hill looking for thermals before they get to the hill.

Is Menefee in SoCal? You should check out some established slopes first so you can get the hang of the basics, then go exploring. I've had great luck trying new spots, and have found some unbelievably good slopes.

Status: offline 		Never mind I found you on Google Earth. Yes you should invest in a high start. Depending on your resources all you may have to mail order is the elastic tubing. If you can get some one to sew for you they can make a parachute for the end. The line can be woven survaying line. Get woven as the twisted get tangled after a fasion. I make it out to Temecula about once a month and could bring my sailplanes and high start. That field looks decent. Send me a PM with your phone number.

By the way my grandmother owned the two sections of land just across the main road to the east. Used to walk all over the hill that now has the houses on it hunting rabits when I was ten years old. Father was born on the corner south of you where all the trees are.

Status: online 		If you plan to thermal, then yes you do need a highstart. On most outings, you're going to launch-glide-land a bunch more times than you're going to find a thermal strong enough to use.

Thermal flying is often an exercise more correctly called, "landing practice".

The probability that you will find lift one each launch depends on a number of things:

The higher you launch the more chance of finding lift. Some days you're not going to find any at all. Some days you're not going to find any for hours at a time.

The larger your glider, the more chance to use the lift you find. And large gliders often find lift that small ones never got to. Large ones cover more ground from launch height. So they can search more area for lift. And they don't come down in still air as fast, so they're searching longer. And small ones often don't "suck up" nearly as good as large gliders do. I've been out a LOT of days where the 2meter gliders were all doing landing practice while the standards and larger were specking out.

If you're only going to fly a discus launch glider, then don't sweat the high start. Learn to THROW the sucker. Small gliders like that spend a lot of time coming down, and the quicker you get it back up the better. The advantage will be that you'll not waste time with the highstart. You'll be in the air as often as your arm will hold out. You can also work each landing toward where you think you might find lift, and launch from a new location every launch. And with a small glider, you're going to need to launch a lot more than with larger gliders.

Status: offline 		A dust devil is the tail end of the thermal. Most of the useful rising air is above it. Kind of like the eddy that goes down the tub drain after most of the water has passed.

In your area there is a weather phenomena called the desert-marine shear line. Apparent as a wall of smog. This can extend from over Lake Elsinore to Banning-Beaumont. This can cause super size dust devils that are not associated with an isolated thermal. As a kid growing up in Perris in the 50's we would ride our bicycles into these trash churners. Sometimes we would get knocked off the bike! Not useful for thermaling as it may re-kit your plane.

Again; we are going out to Temecula this week end. I can bring a highstart and a plane or two. All you need to do is give me a phone number to get in contact with you.

Status: offline 		hello, gliderguider I live in Wildomar and have been flying mostly power planes. I now have an olympic II glider and a couple couple of 1/4 scale sailplanes set up for aero tow. As work has me out of town most of week my best chance for flying is on weekends. The local club I belong to is too crowded for gliders / sailplanes on weekends. Sure would like to get with someone who flys in this area and has used a high start. I haven't found any fields were guys are flying gliders around this area yet. Thanx for any help you can send this way. Dan
