Big Gliders for Aerotow

Check out these beautiful big gliders for aerotowing these awesome pictures off the net, EYECANDY for R/C glider pilots.

Its a half scale ASW 15

Check the TUGS at this meeting.


Huge FOX in action

Very inspirational "we" could make it happen here with a little effort.

Aerotow open letter

Hi Michel,

Thanks for the lovely post on gliding in Italy , as Derek mentioned there is talk of possible doing something here in S.A .
On the left you see Kens Ka8 about to lift off, you can see the red marker on the tow line on the right.
The guys in Durban (Russ and his sidekicks ) and the guys at J.OM.A.C. are into aero towing, in fact at JOMAC they are now only launching this way and have a lot of experience. Groengoud field would be a better option than JOMAC for aerotowing as its all lawn and one can always take off into wind, and landings are easy. Charl is also keen to make a strip /runway into wind on his grass farm, and this could be another venue.

So whats the hold up... we need a few competent glider pilots who can also fly a tug and then we need a couple of big tugs , I mean big, 100 to 150cc size.(Wilga's Pawnee's or Cubs would do nicely and fit the scale profile.)

The JOMAC tug is an Ugly Stik (big version) with a 1.5cu in fourstroke and it tows up gliders in the 3.5 to light 4mtr class , Adrian is the tug pilot and knows his stuff , so he could help and advise.

In discussions with most of the guys who fly big gliders at the slope, there are plenty of guys who would be keen to explore this method of launching and it would give us the oppurtunity to fly the big stuff more often.

Michel if you want to drive this idea , I am sure there would be support.



ps. Get yourself a copy of Paul Natons(radio carbon art)PRO AEROTOW, the 10mtr ETA being aerotowed is mind boggling.

A great day in Italy

At the middle of June I went to Italy where I visited Marco Riva, the owner of a well equipped Model shop "NonDireModellismo" with his partner Samuele. He invited me to spend an afternoon at their flying field. What a nice and organized set-up. Parking separated from the field, a shed and a beautiful "Blanket-Grass-Field".

They do both, motor and gliding. Firstly, Samuele with his fantastic 150cc Plane,

an absolute ACE flier, he has been appointed to do the Tug for the afternoon. They use a 25m long line (cotton) with a breaking strength that if the glider or the tug-plane is in difficulty and the release mechanism is faulty, a strong pull at the line would cause it to break.

After a nice show of expertly done loops, stalls, inverted flying, etc, etc, Samuel started his "Job" as the tug-pilot. There were a 4-5m Discus, a Nimbus and other three models, all in perfect condition and majestic looking.

A 120cc red V-tail tug with a wood prop is normally used to do the "Donkey-Work". First to go is the Discus Piloted by Mauro, a very gentle and clean takeoff and in less than half a minute the glider is at an altitude well over our winch launch. The glider hooks-off, turns to the left, the tug dives after a sharp right turn and comes to land to pick-up the next waiting glider, just like in full-size.

Unfortunately the tug had an engine problem, no sweat, another plane was brought in, a made-shift harness was tied around the wing joiners and the new tug was ready for the next launch.

The thermals were great and the scale-gliders were just magnificent to watch in the late afternoon sky. Sunset was towards 21.30-22.00 hrs and this felt that the entire afternoon was an entire day.

I had great fun watching and participating in the action.

I like to thank Marco for the invitation, Samuel for a Champion display, (he is by the way an Italian champion!), Mauro and all the other members for a great day. Next time I will take along a glider and will contribute to the spectacle.

BTW: if you need some special parts, servos, radios, receivers, motors or anything else in the modeling spectrum that you cant get in SA, call me and I'll put you in contact with Marco, his prices are very reasonable and will be sent (a combined order) with UPS and in two days you will have your goodies!
