Quark 2M - Back to cutting innocent trees!

[JohnPearson]

Hi Guys

Sorry, for not answering your questions, I have had a busy few days, between weddings, work and going to see Lee Evans in concert. So!!! I did a little work tonight on the wings of the Quark 2m, one side completed.
I went with the 10mm carbon option on the main spar and used the 10mm aluminum on the back( the model shop had only 2x 10mm tubes instock.


A little glue and all the spars are in place

The wings do take time to build, however you must be careful to get everything straight and level for maximum performance in flight.



Starting to sheet the wings in light balsa



Oneside of the wings finished

Not much done tonight but I should get more build time tomorrow and maybe get the wings finished.

Andrew the fuselages, build by a professional glassfibre company.

Cheers for now!

Hi all, well I managed to get the wing finished today and sanded, already started the next wing, so will try to get this finished for Tuesday evening, then we can get covering and install the servos and control rods. The wing has taken slightly longer than I expected, however with the design used it is both light and strong!


Port wing finished and ready to cover with solarfilm 'colour ?' :?:

I think Fred is ready to go for a test flight, so I will have to get my finger out and get moving.

Happy landings

That's a BIG aileron  :shock:
Should roll at some rate.

Looking good John. You & Andrew are coming on well. Mr Richard has been surprisingly quiet  :?:

[Fred]

Good work as usual Mr P!  :clap:  :clap:
Building part of mine is done. Starting the finishing stage now  





Weighted it at this stage (never weight my gliders, but I know the question is going to pop at some stage!), and it came down at 900grs.
Only the covering and electronic to go, so that is going to be a relatively light glider, all without trying to save weight, so it can even be made lighter for all the grams chasers!

[JohnPearson]

Looks good Fred, not sure about the weight at this stage of the build, you could make this model very light if you wanted to, however I like a balance between weight and strengh, due to the landing zones on the slopes I fly off! no short grassed rolling hills here! :lol:

very nice fred
i like the made lighter for all the grams chasers!
hihihihi

Is Thierry saying you should set it on fire to lighten the airframe  :roll:   ?

[JohnPearson]

Hi Fred

Just finished building the Quark 2m tonight, therefore, I hope to cover the model over the next two nights and install the gear. Weight at present is 1.5kgs 'dry'


Quark ready for covering.

Could have her ready for test flight Sat or Sun maybe??? :?:  :?:

[JohnPearson]

Hi

Well just finished covering the Quark tonight. I have kept the graphics simple until I test fly the model, then I may go crazy with the design :roll: Just need to install the gear and balance the model, by the way Fred, what is the CofG, not on the plan??



Quark 2m ready for test flight can't wait to get her onto the slope!

Keep you all updated how she flys!

looking good JP

Hi John,
          That looks really nice, is it available in kit form?
John.

[JohnPearson]

Hi John

This is one of the prototypes designed by Fred,that Richard, myself and Fred will be test flying soon. Not sure if this version will be available as a kit (all wood), that will depend on flight performance, if it is to be added to the Islandmodel's portfolio of short kits.

[rasemote]

very nice
 :clap:  :clap:  :clap:  :clap:

[Fred]

And back!

That thing is really looking good John!  :clap:  :clap:
Can't wait to see how that fly!
Mine should be finished this week hopefully.

CofG need to be determined in more details after the first flight, but in theory, CG is right at the front of the wing joiner. (but you have a full flying tail, so you have lots to play with   )

[JohnPearson]

thanks Fred

I will use the cofg as indicated and see how she performs off the slope. I had a little touble with the wings when I put the carbon rods in and used the rubber bands to hold all together, even with  strong rubber bands, the front of the wings would move out, therefore I added a small carbon rod across the wing slightly behind the leading edge, this stopped the wings parting at the front, however if we moved the hooks forward in front of the first carbon spar, this would prevent the front of the wings parting, therefore, no need to add the extra cardon rod at the front.

I will take some photos Fred, to show you what I have done tonight.
