Congratulations on you recent marriage. The pictures looked like you had a wonderful day. I am wondering what you new wife got if you got a new airplane? :D

Maybe the may hours of peace and quiet while you are building it.

Best wishes Ralph

Back to work this week so less time to build :(

Added a frame around the servo plate and sanded it down so the servo plate was a nice snug fit.



Repeat for other plate. Cut some wood and glued to plate for servos to mount on to.

Ailerons next!

Again really nice work Alistair, I noticed Fred's Quark had his aileron servo mounted on the actual servo cover plate.
He had an aileron servo failure when I flew with him on Mt Leinster and he had the servo changed in a matter of minutes. I thought it was a great idea especially if your landing site has a rough landing area.

Richard thank you again for the encouragement. I will indeed have my servos on the plate as per this picture.



Will add some fibre glass and epoxy to strenthen the wood on the plates.

Another question, the control horn on aileron is attached just to balsa 1,5mm plate or there in the place is something harder what hold the horn?
Thank you.

G,

Your Quark is looking good.

I am about to do my horn and will take pictures later. The horn will be 1.5mm ply and glued to the aileron spar and top sheet at the front of the aileron. I will then add block balsa either side glued to the horn, top aileron sheet and leading edge of aileron. Finally I will add the front sheeting either side of the horn.

Here is a picture that hopeully clarifies what I am doing.



Hope it helps.

Alistair

Thanks a lot Alistair, I'll do it same way!
And about the shape of wings tips?

Here is the completed aileron horn.



Need to add cap strips to aileron.

I have yet to do my wing tips. From pictures I have seen they are not shaped as they are flat at end of wing. There may be a little rounding of the leading edge at the wing tip.

I actually plan to add wing tips so as to protect the aileron for the ocassional cartwheel landing I do. :) Also some protection for transporting as well.

Well I have done the starboard aileron.



On with the port aileron.

Questions if I may.

1) Centre of Gravity. On the plan it is 5mm in front of the front spar. Is that a good starting point or an ideal? I want to balance the model with lead in the nose at the most rear COG before covering, then add some easily removeable lead for first few flights.

2) What is the angle for the tailplane relative to the wing for the initial setup??

Thanks

Alistair

Building nearly completed. Rigged it all up to see how much lead to roughly balance at rear COG. Seems I need 70grams to balance it. So this will be burried in the nose.



Need to add the nose with the lead, then shape the fuz, leading edge of wings, fin and rudder.

Then cover it all.

Thanks Bill,

No rush.

Added lead in nose.



Then took the razor plane and sandpaper to the fuz to round it off.



Makes a bit of a mess :)

Glad I ahve the garage to do this in.

Well my Quark is now ready for covering, shaped and nose added as well.



Covering ordered and should be here soon.

Final sand down with smooth and ready to cover.

Weighed it and came in at 1281 grams.
