Finished Wing Weight and other parts

Aileron will most likely be yellow but my mind is not made op on that one yet. The bottom will get a stripe or two for good measure.

So far the wing is at 135 grams. That includes servos, control horns, basically everything except the remaining covering and a 4 pin Deans connector. I'm honestly not sure if that is good or not. I guess I'll find out soon enough. Tail pieces are up next, it will be interesting to see how they come out.

Hi Wayne :-)

What you have posted is looking good.

I may be told otherwise but I believe that if your fully fitted out and covered wing is under 150g you are doing well.

Just don't have a blow out now and find you go over that.

Tail parts will be a challenge. If you can get those below 15g the pair, covered and finished that will be good. Under 12g and you will be doing very well.

Here is your target weight and aerodynamically speaking:-
http://www.hyperflight.co.uk/product...N&name=dlg-fin
Weight: 5.9 g
and
http://www.hyperflight.co.uk/product...=dlg-tailplane
Weight 6.1g

If you get the pod and boom with 2 servos in @ under 75g you are seriously on a winner. That will be hard but remember it is the back end that is the place where the weight must be low.

This is building up (excuse the punn), to be a great result there for you.

All the best.

Hi Mal,

I agree, the tail set will be the most challenging component to build within modern acceptable weight limits. I will see what I can do with tails included in my short kit and if I don't like the weight I will go off on my own and build something. The fuse weight won't be an issue on this one as I am using a Topsky 3 pod and a boom from HyperFlight. I might throw the pod, boom, and all the electronics on the scale tonight to get a feel for where that is going to weigh in at.

Built some new tails and now I've hit 14g for the pair
Will post pictures at some point today ( took a leaf out of Traian 'a tail building book)
And started covering the wing ...

Made a little more progress on the Manta. Now it is on to the tail and the horizontal mount. Should be interesting to see how it turns out.

Hi Wayne,

That looks so good so far :-)

It deserves to fly well when it looks like that.
What pod and boom are you using ?

Good luck with building the Tail Feathers.
Keenan got into difficulty trying to build his Tail Feathers.
He had difficulty getting the finished weight down.

He has proposed going with the way it is being done on the Evolution W:-

I do hope this is helpful.

All the Best.

Hey Mal,
I did manage getting the tail weight down to 14.8g for the pair covered
And they still seem stiff enough for my liking. Also I have still yet to cut weight saving holes in my Flapperons, the new of can out nice and light too
AUW including boom is 248g (minus rx and lipo)

Here is some pics of the new tails
The wing has also been covered now

I am using a Topsky 3 pod and the boom is from Hyperflight. Hopefully I won't destroy the pod during my DLG learning curve as I am hoping to use it for a while. They are hard to find.

I have been watching the thread on the Evo W and I am on the waiting list for a wing kit on his second run. I am very impressed with his design and I am eager to see it first hand. I will try to get some weights of the tail pieces that were included in my Manta short kit. It would be interesting to know where I am starting at.

Hi Keenan,

From your photos it looks like you are going for No Rudder, All Flying Horizontal Stab and Tissue covered tail feathers.

That is an interesting set of choices.

I assume you will be able to get the wrinkles out of the tissue ?
It will be good to see how you do with your All Flying Horizontal Stab Mount and hear if there is any weight penalty there.
Are you buying a V-Mount for your horizontal Stab or are you making that?

Flying with no rudder has been done on DLGs to save weight in the pod but I don't think that will be an issue for you. It will certainly have you working harder with the Ailerons/Flaps and elevator to get nice thermal turns.

Your work is looking good and it will be good to see how it comes along.
Fortunately the good weather seems to be here more now. So you should get a good bit of flying time to set up and trim your bird.

All the best.

Mal :-)

He doesn't list every kit on his website. It is best to contact him and see if he has any or will cut you a kit.
