RE: CMPro Ventus- 2HX 2600mm

Hi Buzz.

Sorry but I re-weighted mine and, with 2.2mAh 3S Turnigy pack, she is @1.7 kg.

If you put turbulator on wing and stab , you will transform the thermal performance.
I also put...

RE: CMPro Ventus- 2HX 2600mm

Absolutely not. Almost all of CG location from Fly-fly are wrong. If you read the full tread of Ventus, Discus or DG1000, it is worth doing so. Any way, CG location is as far as 70 mm. Between 50/55...

RE: CMPro Ventus- 2HX 2600mm

Ok Buzz. As I am on vacation and weather is decent here in Belgium, I'll fly mine as well.
By the way, mine is not that heavy at around 1.3kg. And with all the mod she is thermaling pretty good......

RE: CMPro Ventus- 2HX 2600mm

Hi guys.
Yes, kit spoilers are no good and on the wrong position. Take a look at the forum DG-1000 post #6. I re-position the electrical spoilers where they should be scale-wise on the...

RE: SLS for Ventus 4m

Thanks for the advice. But I think that, as the SLS with motor is pretty close to the CG, I wouldn't have to add nose weight, even take some out as the heavy actual brushed motor is sghtly backward...

SLS for Ventus 4m

High guys.
As I would modernise my pretty old Graupner Ventus Cm (the one ever propose in the late '80'ies i guess), I would change the "up&go" motor or even the all system to a modern like SLS...

RE: longitudinal dihedral

You are surely right but this glider doesn't want to spin...As it have no ailerons, it just do a slow flat spin...when things goes as thought. Not easy to pull her down when she doesn't want...:D

RE: longitudinal dihedral

;) yes it is. I design and built it from scratch being fed up of kit to learn flying. That was around 1990. She is now still flying with latest technology as Lipo and outrunner motor after a few...

RE: longitudinal dihedral

Thanks Matthews for the info. I did design a few planes from very slow sailplane (wich I used to learn flying) to intermediate and F3A. That was a lot of fun and dust :D...Now with reduce evening...

RE: longitudinal dihedral

Paul,
I am not argueing, just trying to have information, understand and know how to set the stab incidence.
Sorry if you missunderstand me.

Paul,
I am measuring that, the plane fuse straight, measuring the difference between elevator and wing incidence.

RE: longitudinal dihedral

well, it doesn't really reply to my question. Do not mix wing incidence with V longitudinal dihedral. The V angle is related to wing incidence by construction, CG and flying caracteristics.

RE: longitudinal dihedral

Thanks Ranfred but no.Angle of incidence is refering to the fuselage axle. The call "V" angle is the angle between the wing cord axle and the elevator axle. That give you the way the plane fly, tail...

longitudinal dihedral

Hi guys.
As I am setting up my Jamara (Fly-Fly) Discus CS 2.6m, I measured the longitudinal dihedral (Vé) and found it at 0°. I beleive this is not right. I thought setting it up to 1 - 1.5° by...

longitudinal dihedral

Hi guys!
As I am setting up a Discus CS 2.6m from Jamara, I measure the longitudinal Vé at 0°. I guess that is wrong. I thought about 1 to 1.5° should be best.
Any advise?
Thanks.

RE: Turbulators, are they supposed to stick up from ribs or be even?

Hi guys.
Take a look of what I did on both Fly-Fly DG-1000 and Discus CS from Jamara, following some advise from French magasine RCM. From many forum, it seem to work and even transform the gilder,...

RE: MARUTAKA cessna Skymaster Kit questions

I partly agree with you but the good thing of modern electric power is that it is lighter than glow one. This plane is already quiet heavy ( not as much as the Aviomodelli / Mantua one but still)....
