Martin/Gordon,

Thanks for the delivery of my plan pack. Can I please confirm the thickness of the tailplane? The plan says two laminations of 3.18mm sheet but the typical cross section seems to show it as being 12mm thick (2x6mm). Two laminations of 6mm would seem better for containing the joining tubes.

Your recommendations, please?

Steve

Hi Martin thanks for checking that for me, I'm going to look again now but I read your Gamma build blog and you said that it was neater to use 48" balsa fuselage planking. I think you used 36" originally but you had to join the planking.

 

I think for me it would be much easier to use the longer sheets for planking but your wood list suggests 36".

I may have misunderstood.

On your wood list you mentioned "10 sheets of 1/8" x 4" x 36" Med/Soft balsa for tail-planes and fuselage planking",

I added 10 x 48" sheets, so this could be why I'm getting to £60.

 

Would you say 8 sheets of the 48" 1/8th would be enough?

 

***********Edit*******

 

I've just read all the posts in this thread and you have already addressed this,

So I think probably 7 sheets of the 48" 1/8 should do?

 

Andy

 

 

 

 

Thanks

 

Andy

Martin, thanks for that detailed list. Helps a lot with getting organized and ready. Here in the USA, I’m ordering the wood I need from National Balsa in Ware, Massachusetts, and their inventory matches your specs very nicely. Piece of cake!

Hi Steve,

During the Gamma build, it was noticed that the plan shows the tailplanes are made from 2 laminations of 1/8" balsa sheet.

THIS IS INCORRECT! it should be from two laminations of 1/4" as per the cross section.

Martin.

Can you clarify something please. On my plan the main spars are noted as 1/8 by 1/4 but 1/8 is too small for the rib.

On the wood pack list it says 3/16 x 1/4, but for some reason I've bought 1/8 x 1/4 spruce spars.

Andy,

If you are using spruce then you can always add some offcuts of 1/16" balsa to the tops of the spruce spars.

The prototype and Gamma builds only used hard balsa spars, so I don't think you will have an issue!

Martin.
