Some questions about gliding!

[viper1990]

Erm ok, i don't know what got me interested in gliding suddenly..., maybe because it can last very long in the air will good flying skills.

ok ,anyway i am creating this tread because i have questions about thermals and winds and location to fly.

I'll seen most post about gliding in this forums..states that bedok reservoir is an ideal place to fly because of the slope.

Anyway i stay at the west side of singapore so it'll be most unlikely i travel so far just to fly a glider there

My area in the west is facing Tengah airbase... yep, means lots of wind comming in from the north side. No building interference. (i'll post a pic i show facing tengah airbase which is in the forested area)

Ok..next is whether if is possible if a glider is thrown off a HDB building with wind blowing head on. Because my house is facing direactly towards a considerbly large field (what you see is 1/3 of the whole field)

It is true that building/roads give off more thermal then grass fields

Erm, those reading my tread and don't know what i'm talking about..i'll summarise haha..

1) it is possible to control a glider that is tossed off a building

The next question is how u gona retrieve ur glider after u r done!!! Those staying there will worry when will ur glider come smashing into their flats!!!


Do fly wif care.

Looks like quite a big area. Maybe you could locate yourself at ground level and have someone launch the glider from above?

I would suggest that you try it with a smaller and inexpensive glider first.

At ground level you can land the glider.

My $0.02.

Welcome to the world of powerless gliding. I too started glider only this year and really it's something you need to experience for yourself. To help you see my reply in bold.

I'll seen most post about gliding in this forums..states that bedok reservoir is an ideal place to fly because of the slope.
Bedok reservior has been bless by it's facing toward north-east. So during the north-east monsoon the wind blows directly onto the slope face 010 - 020. With wind around 12knots you get fantastic lift. I have to emphasize, NO PROPULSION of any sort. It has to be pure glider.

Anyway i stay at the west side of singapore so it'll be most unlikely i travel so far just to fly a glider there
I believe there a lot of glider pilots that are looking for a slope to fly all year round but have found none. Anyway BR is like a pilgrimage for slope flyers where we get together during the season.

My area in the west is facing Tengah airbase... yep, means lots of wind comming in from the north side. No building interference. (i'll post a pic i show facing tengah airbase which is in the forested area)
Becareful as there are restriction on how near you can fly near any airbase or airport.

Ok..next is whether if is possible if a glider is thrown off a HDB building with wind blowing head on. Because my house is facing direactly towards a considerbly large field (what you see is 1/3 of the whole field)
That's a BIG NO NO! You do not know how the wind is deflected when it hit a building. Furthermore you may hit someone along the corridor or someone home.

It is true that building/roads give off more thermal then grass fields
That's true. Anything that gives off heat from the sun will produce thermal. Land or fields that has little grass will have some thermal effects. Unfortunately we don't really have places like this.

Again don't do that. You maybe caught for killer litter.

Wow, thanks alot! (chiadennis)you answered most of my questions! haha... alright..maybe the first place i launched will be bedok reservior..., when i find time.

There is a season for it, not anytime also got wind blowing the rite direction. Season starts end Nov to late Mar.

Happy gliding.

hihi all bro, i juz got a easy glider with a 2200kv bl motor, how does flying a glider feel compare to a formosa1? need some tips for catching thermal n slope soar.. thx!

[chiadennis]

These are 2 different class all together. Like driving MPV and EVO. You still can do basic acrobatics but easyglider will not perform stunts like famosa.

Catching thermal is an art. When you are gliding (without power) you may notice the glider start to raise on it's own, you may be caught in an updraft or thermal bubble. The thermal bubble move with the wind direction just like releasing a helium balloon. You may need to mix your aileron and rudder to do a quick turn to help search for more thermal.

Slope Soaring use the dynamics of wind against cliff or hill slopes. This create an updraft wind. Again such soaring depend alot on wind direction and speed of wind. When everything is in your favour, you will find your glider not wanting to land. The wind will keep pushing your glider up. This is where incorporating speed brakes or crow braking comes in to help in your landing.

thx so much!. juz maiden my easyglider todae, do i use headwind to gain height or tailwind? i find that landing against the wind is not easy as the glider catch the wind and keep staying afloat even with the power off..

Taking off and landing should always be into the wind. This is sometime not so easy. For gliders they catch the wind very easy so cross wind and into the wind landing provide a challenge. What you can do is to have speedbrake setup for your glider. Speedbrake kills your lift so that you can come down. Remember to add a little elevator to compensate for the the lost of lift.

Alright...another question..um, like you said..gliders catch wind easily, dose it means that a big gust of wind send the plane flying backwards?

Hum..., in that case is there any methods to maneuver the glider back to you? its like fighting against the wind

I posted a picture to clearly illustrate what i'm talking about ,haha.

I order for you to penetrate the wind, you may need to ballast the glider. What this mean, you increase the weight of the glider without changing the CG point. When you launch the glider you would normally have down elevator. Unlike flying power planes you normally pull back your stick. When you get into trouble push down.

I wish to ask too;

For gliders;

Where do I get just receiver batteries? That means batteries that plug directly into the receiver? No propellors, right? That means the batteries that feed into the receiver which controls the servos.

4 x AA/AAA batts will do.

If u feeling rich, a 2S lipo wif BEC.

U come see my batt, I show u my Flying Bat glider n 4 x AA rechargeable batt.

sure thanks...
