You need a highstart with small diameter rubber tubing (1/8") and you
would have to either permanately mount or temporarily tape-on a hook
just in front of the CG under the fuse. Aerofoam.com sells high
quality highstarts or rubber. Here's a link that shows a tape on
hook:

If you just want to try it out, you can make a cheap highstart out of
no. 64 rubber bands and kite string. Loop the rubber bands together
for a length of 12 to 15 feet and add 50 to 70 feet of string. Use a
keyring (Walmart sells a pack of them for about 79 cents) on both
ends of rubber and the end of the string. A large aluminum or steal
nail with a large washer is used for a stake.

You can tie a windstreamer a few feet ahead of the towring to make it
easier to find in the grass. Cut a strip of supermarket plastic bag
(bright colored).
The only problem is that the rubber bands have no protection from the
sun (UV). The rubber lasts only a short time.
When rolling up a highstart, roll up the string first.
Remember - roll up the string tight and the rubber loose.
