Wow, incredible!!I'm done, I'll maiden next week. More over at the Master Spitfire thread.
Way more work than the standard build, for me at least.

I personally don't like relying on just a foam spar, I either add a 6mm cf strip or use 2 layers 1/64" plywood sandwiched inbetween the foam. Nice part about the plywood is you can usually find it in 2 foot lengths and the big bonus is you can cut it with the scissors.Starting another Spit today.
I was going to say the opposite, that I usually only use foam for my spars, and then I remembered that I broke mine on my spitfire, so yes - a popsicle stock or something would help. I did however mess up my spar on the build and accidentally broke it before installing it, and also mine saw a number of crashes, so if you treat yours better than I did, you might not have a need for more support. Anyways, it only adds a couple grams of weight and might save you headaches later.I personally don't like relying on just a foam spar, I either add a 6mm cf strip or use 2 layers 1/64" plywood sandwiched inbetween the foam.

I always tend to over do it but better safe then sorry.Can't hurt to add a wood spar but I've had zero issue with the 3 Spits I've built. (oh BTW, I never got that spar over lap to work correctly, must be an error in my template making). I attached all the wings halves together, using the P 40 video built technique. (Packing tape is really strong in tension. ) One of my spits has over 75 flights. I do think it's a good idea, just don't go over board. ha.
You should be able to find it at your hobby store , usually the ones that sell balsa and such usually have the hobby grade plywood at different thicknesses.@Wildthing - where do you source your plywood and I'll be backing up the foam spar with some bbq skewers on this one. I think the template for the Spit might be wrong in that the long sides are both on the front or back.
Some of the craft stores sell it also, our Michaels here stock some of it.@Wildthing - where do you source your plywood and I'll be backing up the foam spar with some bbq skewers on this one. I think the template for the Spit might be wrong in that the long sides are both on the front or back.
On the standard Spitfire plans, the two spars aren't quite right. They're mirrors of each other, but they should be exactly the same so that they mesh properly. I ended up cutting two right wing spars and didn't have any problems.Can't hurt to add a wood spar but I've had zero issue with the 3 Spits I've built.
