Hi,

How does this thing fly without a motor?

http://rcbazaar.com/products/640-salto-glider-sail-plane.aspx

they are gliders...!! suppose to  fly winthout motors...!

http://en.wikipedia.org/wiki/Gliding

i mean, this one has motor http://rcbazaar.com/products/633-asw-28-electric-glider.aspx
other one  doesn't .

it all depends on how u want to fly..!! take the plans  high up and then disconnect...! or start gliding from bottom...! on a slope  or get the glider  towed to the height by another plane...

just read about gliding and u  will understand...! that is the real fun flying without the motor..! if u  sit in a real  glider.... trust me " IT IS SHIT SCARY"

or just slope glide like this

During launch you will give the plane enough energy by throwing it as high as possible. This energy will be used during its entire flight. You may even notice that hand gliders have very less weight and their shape is very aerodynamic to avoid losses due to air resistance. However a small battery is used for receiver and servo operations.
Watch the video below and you will understand bit more about it.



There is also a human powered plane and few other gliders in flitetest channel which are launched near the cliff sometimes so that they have very high potential energy which will serve as energy source for gliding action.

If possible, take a joyride just before sunset, when it is calm.
The winch launch may scare you due to the speed (~70mph) and the steep climb (~45deg).
But once you release the tow cable, believe me, you can't have a more peaceful experience.
No engine, no noise except that of the airflow (~45mph), no vibration, no bumps.
Something to be cherished.
Do try it...

Hi Srivatsa,
A Glider is an aircraft without an engine/motor.
It has to be launched to/at a height (hilltop, bungee, winch, auto tow, aerotow) from where it glides down.
A Sailplane is a Glider efficient enough to gain height after launch, using updrafts from thermals, slope lift, wave lift etc.

The RC Glider duration record is over 36 hours.
The RC Glider speed record is over 500mph.
No engine or motor!

Nowadays most model glider flyers prefer an electric motor equipped one, as it simplifies the launch.
Once at the desired height, the motor is turned off, and the rest of the flight flown without power.

There are alternatives, though.
If you are interested, I'll post links to some of my threads on this forum, that have relevant videos.

Mr Reddy's post/video is of a DLG, which is a special case. Usually under ~300gms.
That Salto is 1.8 kg.

If you are thinking of buying it, my advice is please don't. For 2 reasons.
1. You may not have the equipment to launch it
2. You may not have enough space to land it!

Incidentally, I've seen only winch launches so far (full size)
IITK may be doing aerotows. They have powered gliders too now.

Regards
