I am about to build a Mick Reeves 1/6 Spitfire. All previous experience is from build kits that normally come with all the Hardware. However the Mick Reeves model comes with all the main shapes pre cut, but all the sheet and Spars needs to be purchased separately.

So my dilemma is making the correct choice of wood density for the build. Can someone please give guidance on what density to use eg, light medium or hard for the following areas:

1. Wing sheeting (i will be using 3.32" sheet).
2. Packing between spars.
3. Wing spars 1/4 by 1/4 (top and bottom)
4. Ailerons and control surfaces.
5. Wing leading edges.

Any other tips will be greatly appreciated

Thanks in advance
