high start line

[xtc]

how much line would you add to 100 ft of bungee cord??

Depends on how much room you have to launch at your flying site....I have used 300 ft of line and down to 100ft..I used 40 pound test monofilament...

[Soar_dude]

Are we talking "bungee cord" or Sugical tubing? If it is bungee cord I would not go more then 200' of line mono or braided will work. on the other hand if it is sugical tubing go with 400' of line. How heavy is your glider the heavier the glider the less line you use.

what i have is not surgical tubing,it is the mattrel dipped stuff from house monster .com

i have about 1000 ft for flying field 2.5 meter [900 sagitta]
2.8 metre full house [sobox harpia]
i purchased the cord suited for 3 metre ships so i should get a good luanch for the hundred inch RES

im thinking that i might use 400 ft???

thanks guys xtc

I have seen 3:1 as the recommended ratio. Add more line to that ratio if it is windy and take some line off if it is calm.

I use 280 feet of monofilament to 100 feet of 3 Meter rubber. Not quite 3:1 and with the wind around here I could certainly use more. I have read that having 50' or 100' disconnectable sections of the line is an advisable thing to do, I just haven't seen the need just yet.

I have the same tubing from Hosemonster. I have about 400-500' of masons line on mine (actually I'm not sure how much, but stretched about 3:1 it's almost as long as our field, which is about 1000'), lauches 3+ M ships no problem as long as there is some slight breeze. Could probably be shortened for dead air days.

I concur with RSCherry if you have the room for it use it but I would use a light weight braided line(lighter then mason's line) so you can get higher launches.

Hosemonster makes vaious weights of elastic so you need ot be more specific, I think.

I have 1/2" surgical tubing (3/32" wall from NE Sail) with 400 feet of masons line. We launch 2 and 3 meter ships on this all the time with no problem.

If you are unsure, put on 300', then add 50 to 100 foot sections to see how she climbs. I have 50 foot pieces set up with snap swivels that I use with my 7/8" up-start or the full hi-start to extend them depending on what is being launched and what the conditions are. Lighter line might work better but this is how it came from NE Sail.

Masons line is inexpensive and quite functional. You could spend $15 more for very thin and strong spectra line of the same length that would give a slightly better launch. Mono filament is a good inbetween choice.

[RSCherry]

To add to what Ollie said, I also like the masons line because it's easy to see on the ground. Mine is a bright pinkish color which is very easy to pick up visually on the ground.

aeajr he said it was the three meter stuff so that would be 3/8" od 1/8 id. that mandrel dipped stuff is awesome. I bought mine when Hollyday was selling it is 4 years old now still pulls like it is brand new!!! I agree with Ollie about mason's line being functional, but it creates alot of drag because of the bigger diameter. If the field is short grass I would go with the mono fishing line it is light, and less surface area. On the otherhand if it is a rough field go with the mason's line. another suggestion is to join the line in 100' length's so that if you are at a smaller field, calm air, or down wind you can take line out of it to compensate for conditions.

I'm sure this is a silly question, but could someone tell me why you use more line on a windy day and less on a calm day? I've never tried this variable line length, but I too am setting up a new highstart (100' hosemonster with 2 rolls of 225' pink mason line) and will be trying it. I just was curious how it helps. It seems that you would want to add more on a calm day to try and get the plane up higher. Sorry to add to the confusion factor. :confused:

On a calm day, you rely on the pull from the high start rubber only. On a windy day, the wind helps "kite" the plane up. The extra energy provided by the wind allows for a higher launch.

Yep! What he said!

Thanks guys for the education. That's why I like this forum so much.

i use a high start with a short amount of string and no parachute and get high enough with out much walking,,i get a zoom launch..i use my own tubing the hobby shop stuff is weak.
