Gliders > Slope Soaring
First the good news......and then the bad news.
Fred:
Hi Keith,
Nice to see some good building ! :clap: The glider is looking really good ! :D
Shame about the "non controlled landing" tho :P but that will be really easy to repair !
--- Quote ---I found the ailerons very ineffective, probably because of the polyhederal wing. (Could that be the reason Fred?)

:?: hmmm, I have to see it flying to be sure... What's the glider is doing when you put the ailerons is important, but seeing the photo of the glider in flight (the first one), looks like you need more differential on the ailerons, that will help a bit! CofG can be double checked too (to remove a bit of the stability)
Also, with "real" gliders :P :P like that one, you need to use the rudder to turn... Ask Joe, but if he comes near you with a strut or any hard piece of wood, run ! :lol: :P
Going to be a cool relaxing machine to fly in thermal conditions
Happy Days:
I'm very interested in your comments Fred, thank you. :D I suspect that you are right about the differential. The manual says the ailerons should have 19mm up and 9.5mm down. However So far I haven't been able to get those degree of movements. They are moving 15mm up and down.
This kit can be built with either wing configuration of straight or polyhederal.
Reading one of the review write ups, I noticed that the reviewer said that he would not build ailerons into the wing if he were to build a polyhederal wing. He said he would just fix the "ailerons" in a netural position and turn with rudder only. That's why I wondered if the shape of the wing was effecting the ailerons.
Vis CoG: Are you saying that to move the CoG back would improve the roll rate? (I'm a little uncomfortable with the thought of moving it back in case I can't control the plane after I've launched it!) But it's worth a thought.
As for Joe, I think he's enjoying lots of sex, drugs and rock'n roll in another country at the moment. :clap: (Well,.......maybe not the sex as he's a happly married man.............So I'm told.) :lol:
I'll have another look at those ailerons and see if I can get the correct degree of movement. I'll let you know the outcome
Fred:
:lol: I think Joe is gay now... Well I think, he spend lots of time with men on tour these days ! :P :?: :?:
The polydiedhral add stability, but I think that is good to have the ailerons anyway, that help to keep centered in the thermals, and you can also play with the camber of the wing on the full wingspan.
You van now use all the switches and stuff on your radio ! :P
For the differential, if you can't have an electronic one (via the radio), try a mechanical one (move the rod to another hole and so on.. that will gives you a little bit of differential...).
For the CoG, the best is to try your actual one (45 degrees dive, release the sticks, and see what happen !)
But my best advice will be to use the rudder with the ailerons.. That's a good excercice, and almost a "must do" when flying gliders.. And no radio mixage !! That is cheating ! :P :P
Happy Days:
:lol: :lol: :clap: :clap: :clap: Yes, your comment about Joe is very good! (It made me laugh out loud.)
If I were to start building this model now I think I'd build it with a straight wing. Thermal flying is not realy my 'cup of tea'. I prefere the wind in my face standing on a high ridge. "Man verses the elements", sort of thing. But we all live and learn.
I'll try to change the aileron diff. this afternoon and hope to take her out for a trial tomorrow..
Not too sure what you mean about the wing camber, but we've had a similar conversation before, I'll wait till I see you next and maybe you can explain it to me.
I'll let you know what happens when I put her into a 45 degree dive and let go.
Thanks again Fred. (It's good to know there's an expert on hand to point me in the right direction.) :D

:?
How you guys see all that in a photo I'm yet to discover!
