Thread: Awful landings - advice requested
18/08/2017 15:15:33

 

 

How to land your slope glider.

It's very easy if you just do it like this:

smiley

Here the wind is a bit off to the right, so I start the approach from the left, then there is just a bit more head wind, and it's pretty easy to control the glide path.

Here is very turbolent at the dune top, but as you can see I keep the glider up in the clean airflow and stay there, and using the flaps to reduse the speed and height until I can reach it.
If I just fly 5 meter longer downwind or just a bit lower, then it will fly down in the lee and turbolens air and with that groundspeed it will loose all the airspeed and it will stall and dive vertical to the ground.
Wind 12 -14 knots,

Good luck

Maiden flight with my new flying RC Formula 1 car

(Vintage Graupner GM racer 3D) that I got for free, from a guy in the RC club.
Not that easy to control, but also using the rudder together with the ailerons and a little training if was ok, and loop, roll and also inverted flying was possible.

With some more training I think it will be ok for indoor flying next winter

Thread: Lidl XL Glider

For towing the Lidl glider just use a small piece of velcro, works great for small gliders, and up to 3 meters with experienced people

Only use around 5 - 10 mm for the Lidl gliders, how much depend on the velcro.

To release the glider pull hard up or the motor plane level out and make a half roll and go vertical down.

The pitcheron glider is very sensitive to a forward CG.

To get it to loop try to move the CG a bit back, at the underside of the tailplane there is room for a coin or 2.

Try this, or move your battery a bit back.

To get max throw, check in the dual rate meny.. Perhaps you can give it a bit more there, on a Spectrum tx it can go to 125 % smiley

My ballast is lead,It is 1.5 mm thick lead plate 70 mm long, which I rolled together to 14 mm.

And taped a piece of stainless wire on it so It can be pushed all the way back to the wing spar in the hole.

I say the same thing to the members in my club, get some gliders and go sloping It's so fun, relaxing or exiting all depending if you fly in light air, strong wind, combat or DS devil

Just go for it...

Hi, Soren,

Great flying and very maneuverable, now that is great.thumbs up

Could you give details of where you have you're spar and servo and servo pivot connecting point please.

Could you also measure how much movement you have at the trailing edge .

Cheers Steve

Edited By Stephen Jones on 09/07/2017 01:07:57

Yes..

The spar is at 85 mm from the leading edge.

Servo connecting point is at 30 mm.

Movement on the video is 12 mm up and 22 mm down measured on leading edge.

Cheers

This one with more throw on the steering Max travel on the HXT900 servos and also on dual rate, 60% expo on ailerons and 40% on the elevator. 100 gram extra ballast and CG at 60 mm, and it's working great.
Wind up to 13 M/sec or 26 knots

Thread: Mentor v Funcub
07/07/2017 16:44:06

I have both planes.. laugh and both with big motors for towing gliders up to 4 meter span.

The Mentor feels and fly like a much larger plane.

I have put flaps on my Mentor and this make it much more fun to fly than the stock one, playing with short take off and landings.

We have had around 10 Funcubs and 3 Mentors in my RC club.

The Mentor is pretty ok from the box, but the Funcub really need a better landing gear, and all the Cubs in the club have changed it...

Cheers

Yesterday I was flying it for the first time in low wind speed and no ballast in low slope lift and thermals, and found that the CG at 55 mm was perfect.

On the pitcheron model this give good elevator control and the dive test was as I like a glider to be.

In high wind and with 100 gram ballast I flew it with CG at 50 mm and it was also ok, so I think I am pretty near now.

@Soren

Brilliant solution! Wing twist is the way to go!

Please advise - how far back from the LE is your wing pivot?

Hi

The wing spar is 85 mm from the leading edge

I think we are all predisposed to a bargain, a challenge and something we can personalise.

At the end of the Carbon tube there is a hole on the underside of the wing, and the 4 mm carbonrod is 10 mm longer than the tube, so I just put on a rubber packing (o ring in Danish) and gave it a drop og cyano glue smiley

The CG and weight will come after some more trim flying, the CG was too much forward yesterday due to the 150 gram extra ballast.

The wind should be good later today.
