Nope! Just wont fit with paper tube.

It's an eight mm hole intended for push rods exactly as shown on the plan.

Ah well! If you must use two servos,you will just have to open the holes out

Odd that when I was gluing the ribs in I thought the holes looked small. It would have been easy to open them out before building the wing. No problem I will go with plan B and fit extension leads before sheeting the wing.

BTW you have not pulled me up for removing the wing from the board. Well I had to because I forgot to do something.

Looking at the plug in the rib there are two slots cut into the rib these are for the wing joiner to slot into. I did not cut these slots before fitting to the wing, even though they are shown on the plan. It was when I came to fit the wings together that I realised crying.

So for anyone following along enlarge the holes in the ribs and cut the slots in the inboard R2 rib these are two lessons to be learned. smiley

Wing joining.

First I glued both R1 parts and the pilot drilled hardwood UC block.

Then joined the two wings at last smiley

Using pegs, clamps and weights. The right wing is propped up under the last rib to give two inches of dihedral.

Wings are joined and I have to show you the results.

dscn0437.jpg

dscn0438.jpg

What! No gaps.

party Party time. Yes a result.

And what did I do?

Followed the tried and tested Peter Miller method.

This is the best and easiest of the four wing joints I have done so far. Yes this is my fourth build, two kits and one other plan pack.

Amazing.

Cheers beer

Wing LE sheet which was wet and shaped on the wing a couple of days ago. Completely dry and it has kept it's shape.

dscn0439.jpg

and on the wing

dscn0440.jpg

Doing this makes the LE sheeting easy because it will fit the profile with very little effort.

So now to glue it in place.

Cheers beer

I find it saves all the pins, pegs and tape. It does take longer to do due to waiting for the sheet to dry. If like me you are not in a hurry then there is no problem.

LE sheet done and trimmed.

dscn0444.jpg

Nice joint! and servo extension lead installed so I don't forget this time.

dscn0443.jpg

But I had to use tape on the LE and it was not as easy. I think this could be due to me completely drying the sheet out whereas on the first wing the sheet was damp. Anyway I have decided not to stress about it frown

because it is fine.

More sheeting tomorrow when I get back from flying. smileyyes

After flying my new Phoenix 2000 V2 this morning yes

On to the wing sheeting, as promised yesterday.

Place the sheet on the wing and mark the end of the curve. Use your favourite toffee pot to mark the curves and the left hand straight line.

dscn0445.jpg

Cut the straight lines.

dscn0446.jpg

Then the curves with a sharp knife just inside the lines so they can be sanded to fit.

dscn0447.jpg

Place on the wing and mark the cut line to remove the overlap.

dscn0448.jpg

Cut just leaving the pencil line showing. Test fit on the wing.

dscn0449.jpg

I assure you it is a good fit when pressed into place.

Form a hinge with tape open up an apply glue

dscn0450.jpg

Place on a flat surface and remove excess glue and weight down using plastic above and below.

dscn0451.jpg

Leave to dry and while waiting check that there is nothing else to do on the wing before this section is covered.

Ah yes scrap blocks at the TE mounting plate. Nearly blush

Cheers beer

Fitted scrap blocks, while I remember smiley

dscn0454.jpg

Sheeting has dried so removed the tape hinge from the under side and lightly sanded the top side before fitting.

dscn0452.jpg

Dry fit to wing and make any adjustments.

dscn0455.jpg

Looks good to me.

Too late to glue in place tonight, I will only bodge it up as I usually do when I am tired.

Back tomorrow for more fun smiley

Cheers beer

You flatter me Peterblush

I have a theory that if I make everything as perfect as I can then the better the plane will fly.

I have been accused in the past of being too much of a perfectionist, not that I have ever thought that I was. I simply like to make a good job, which leads to job satisfaction, which is a result in it's self.

With the Ballerina I hope I can do your excellent design justice.

Cheers beer

You are so right! The better a model is built the better it should fly and the stronger it will be.

There is nothing wrong at all with being a perfectionist.

I must admit that when I do strive for a perfect finish I am extremely proud of the result.

Many years ago I scratched a living making desktop models of aircraft (mainly sailplanes) for people and I even had an agent in the USA.

Everyone of those had to be perfect and it was a strain. I did one or two models for my self.

This is my Springfield Bulldog hand carved in limewood.

My control line B-17

andpitts dunlop.jpg

My best, 1/12th scale Dunlop Pitts. static scale. Built as per the full size with a fuselage frame soldered up from brass tube, wings and tail built up and tissue covefred etc and all detail as per the full size including fibreglass spats and cowl etc.

So I can do it when I set my mind to it

Wow!

Unbelievable!

Amazing!

Should I give up now?

Maybe I should work on the basis that if you can do it then I should at least try.

thinking

Yes I will keep going.

Sheeting glued and weighted down, old batteries again.

dscn0456.jpg

I used the tape hinge as the sheet was in the correct position I thought that if I make a hinge, fold it back, apply the glue and then it will be in the correct place when returned. It seemed to work.

dscn0457.jpg

Now the sheeting is done on this side I can lift the wing.

dscn0458.jpg

A bit of sanding is all that is required.

Two more panels to go which I will do without this blow by blow account.

Cheers beer

Wing sheeting is now complete yes

dscn0460.jpg

Dry fitting the wing tip parts to work out how it fits together.

dscn0461.jpg

I am running out of laser cut parts what am I going to do? frown

Buy another plan or plan pack?

The RF4 looks good to me. A club mate has one very similar but a bit bigger, the wings are in four sections, I think it is two thirds scale.

I wonder if I could build a one third scale with a two piece wing.

Anyway that's for the future.

Why not cut out your own parts? Saves a lot of money from what I can see.

Lack of belief in my own abilities Peter.

However you are boosting my confidence!

If I go one third scale I will have to cut my own parts.

Cheers beer
