go to the scale sailplane section and do a search on there im shore you will find lots.gliders from 2m span up to 10+ meter span are normal.the line is atached to the tug on the CoG on top of the plane via a two relise and the glider is towed from the nose via a similar relise so in the event of a problem eater tug or glider can relise safley.tugs are normaley gas poered between 60 and 150cc high wingers

You take a seriously overpowered "trainer" tupe plane such as Cub/Telemaster or similar, place the tug release between the CG and wing trailing edge.

How big/powerful depends on size of field, size of gliders that are to be towed and the skill of both tug/glider pilot. A good pair will tow succesfully on smaller/less powerful stuff.

Towing becomes practical when gliders get bigger, typically 3-4m wingspan and upwards. The rest is limited by cashflow

In my club we have one towplane at the moment, its a huge Telemaster (3.8m / 12.5ft wingspan) and its powered by a ZDZ80 gas motor spinning a 3bladed 24x12 carbon prop. It hauls some 6.3m gliders at 12kg weight up without any problems.

I have some videos on my web page if you'd like to see aerotowing in action. These are all large scale gas tugs but there seem to be a number of people starting to tow with smaller stuff.

Haldor,
That's a great video! Where did you get the 12 foot Telemaster, or was it built with just the plans?

Here you can see towing of two big gliders (5m wing span) at once by one big PZL-104 Wilga model (4m wing span and 210ccm motor).

Here are more pics: http://www.sonix-rc.civ.pl/mrqs/

It was an international modelers meeting at Zar mountain in Poland

Aerotow is a lot of fun.

There are many sites that you might find informative. Start at www.scalesoaring.net

Attached is a photo of my (former) tug and one of my gliders. The tug was powered by a DA100. The Glider is 1/3 Duo Discus, 6.7 meter span.

Might I be brave enough to ask whatever became of your Tug?

Tow Job's last flight occurred at the JR Aerotow in June, in front of everyone in the US aerotow community. TJ simply spiralled in after a tow to ridiculous heights.

Note to all who tow: The glider pilots will hang on until your planes are mere specks in the sky. It is your job as tow pilot to take charge of the tow and simply declare that you are done and would like for the glider pilot to earn his own altitude with some thermal skills.

The height and distance of the tow had little to do with the loss, as I think I hadn't secured the RX switch fully on and it simply switched off. I can find no other explanation... BUT the height and distance did make the recovery a PITA!

TJ is now an organ donor... The engine and servos have all been returned to flight status by their makers.

Yes, TJ started life as a Salto.

A little voice suggested that I simply strap a DA 100 onto the fuse to make a great tug....

I did a bit of nip and tuck and added what turned out to be a ton of body filler to reshape the wing fillets.
