Good point Peter but cleaning that off means it will not be finished by Sunday Fun Flyer laugh

Cheers beer

Well it is not my model.

If Sunday Fun Flyer doesn't mind if lots of joints fail on his model in a heavy landing...good luck to him

But I do think of it as you model Peter.

I have to admit I forgot about the charred wood, which has now been sanded off. Thanks for pointing it out.

I am now trying to work out how to cut and shape the leading edge for the bottom sheet.

That will be tomorrow after a good nights sleep, I hope.

Cheers beer

I've been in exactly that place! It's probably easier to actually do than to think about.

You just chamfer the lower edge of the sheet to roughly match the ribs before sticking to the ribs.

I build the wing with a slight over hang of the board so I can stick mappins in underneath the sheet. Failing that one can wedge short bits of tapered balsa underneath to hold the sheet against the leading edge.

Once the wing is complete and the cap strip is glued on it will be perfectly strong enough.

Thanks Peter that was easier to do than I thought it would be, as Fun Flyer said.

Cheers beer

Trust me. I am lazy and always work out the easiest way to do things.

Very good. I found a strip of TE worked well to hold the bottom sheet.

Bottom sheet glued then shaped the top of the leading edge. Placed the washout wedges under the trailing edge. Dampened the top sheet and now drying in place.

Tomorrow glue it in place and also the remaining top sheet.

A good day today.

Glued the top leading edge sheet.

Fitted and glued the top sheeting.

Made and glued the cap strips up to the aileron.

Tomorrow finish off the cap strips then the leading edge. One wing nearly done?

Amazing how much can be achieved on a cold wet windy day.

Cheers beer

Looking very good EarlyBird. Have a good day's flying tomorrow.
I was flying my RF4 again yesterday. Its quite lively in the air. I think I expected it to be more sedate.

Thanks FF,

I have just lifted it from the board to work on the leading edge my initial thoughts are how light it is and that the wash out wedges have done their job. surprise

Looks like good flying weather today but my main reason for going is to swap onions for apples, does that make it a swap meet? We had a swap meet planned for October but it has been cancelled now sad as we are all keeping each other safe.

Cheers beer

Just a little tip that applies to all model builds.

When fitting wing spars into tight slots in the ribs it makes life a lot easier if you just sand paper the sharp corners off the spar where they go into the ribs.

It just takes that sharpness off that can dig into the rib

Excellent tip and timing Peter.

Leading edge cap strip fitted to the first wing.

Started the second wing surprise

and went flying, also swapped onions for apples. So a good day. Almost forgot I topped up my sun tan. Unbelievable perfect flying weather.

Cheers beer

Cold wet and windy today ideal for making progress in the workshop.

Second wing is coming along ribs are fitted to the spars with bottom sheeting and caps, all dry fit as usual.

Just the aileron to dry fit then it is glue time again.

That will be tomorrow.

Cheers beer
