1/3.3 Ventus 3

[French1]

Thanks Tim

[French1]

Motivating people to build is the master evil plan in the back of this thread.... mouahahah!!!

As far as moving surfaces, one flap hinged at the bottom and three ailerons hinged on top surface. I will try to keep the servos in this wing down to three and just move the last aileron using the second one, a bit like the Duo discus (spring and tab for the aileron to move up and not down). But I will provision a servo slot, “just in case”. I do not plan to add spoilers, with 3 moving surfaces crow should work pretty well..

Nice work Stehpane!

Stephane,

Of course the wing looks fantastic and it sure makes me want to learn this whole process!! Thanks for sharing the steps. I have a question unrelated to construction though. How many flaps and ailerons does this wing have? How many servos will be in each wing? With the sweep angle breaks in the wing, along with the polyhedral breaks, it seems like any surfaces being driven by an adjacent one through a rib pin will be difficult and probably less precise than desired. Interesting details. Keep up the outstanding work and look forward to see it in the air.

Thanks Stephane! I didn't realize the fuselage was a kit version.

[French1]

upper surfaces are done, quite a lot of work remain for the spar, wires and so on, but definitively making progress...

Here why I use peel ply, TE is quite glossy after bagging, it let the finish with a lot of potential grip after removing the peel ply

I will pause a bit on that project, I have a set of DG-200 wings to bag for a friend

[French1]

Mike, I didn’t picked the scale, it comes from my Graupner discus fuselage.

You are the 'Bag Man' !!! Why did you choose the 1/3.3 scale?

Left wing in the work... or in the bag should I say

If that wing is anything like me then it loves its 'lectrick blankey'! lol

Right inner panel turn after my return from Europe

Same principle, two layers of carbon cloth (6oz) 2 in wide for the spar caps and two layers of FG (2.3Oz) for the veneer

Flap 1 will be hinged from top, you can see this one pretty clear on this picture and Flap 1 will be hinged from the bottom to allow more deflection

Hello Kitty! Looks great!

Than makes sense.

thanks for the explanation

Stephane,
Back in 2000-2005 I did a bunch of vacuum bagging when building a full scale, but I would apply release cloth, breather cloth, etc, before bagging the piece. In your photos, I don't see those sheets? Are you using a different process or had the technique changed and products evolved?
Nice work and thanks for sharing this build.

Yes Len it is a different process, the one you refer to is the one have used for hollow core wings. For foam core wings, no need of all of that as the epoxy need to migrate in th styrofoam to grip to it.
