Well, Brad. Things like this can be quite discouraging. Congrats for getting back in the saddle and fixing the problem. What was built once can be built again. I still have this on my 'one day' list.

KABOOM!!!

I destroyed the front of the plane last night  Angry

I was drilling out the hole for the thrust button.  I was on my third and last size bit when the bit caught an edge of the 1/64h ply and torn the front off!!  I had been worried that I hadn't done that sooner and now I've learned my lesson.

I was able to piece it together fairly well.  I have some gaps to resolve, but it's pretty square.  I'm thinking I might infill between the stringers with soft balsa sheet and sand to shape.  It would add strength and help me hide some issues with the repair.  The plane is tail heavy, so I'll need to add weight upfront anyway, so I might as well make it structural.

I finally had to tack a small cross piece to hold the V-tail from spreading and crack when upside down.  I've broken it many times Smiley  Also working on the landing gear.

After getting several comments about the fillets, I did dive back in and took additional material off the underside.  I got quite a bit out and yes, they are now quite thin  Smiley  I had to patch two holes.  I also got the underside fillets in place.

I'm close to thinking about covering.

Tom:  the first two photos are the initial cutting of the TE stock to shape, the next two show some shaping.  I did remove at lease 1/2 the overall material from the top and bottom.  Once I attached them, I removed even more as I shaped them.  The wood is very soft and light which helps.  I'm hoping my next batch of photos will show them much more streamlined.

That's going to be one sleek looking bird.  Are you going to hollow out the backside of those fillets?

Fun with fillets!!!  I have my top wing fillets done  Smiley, these shots are work in progress.  I used a tapered trailing edge I found in my wood supply and it really worked out well.  I'll post a finished shot soon once I have the bottom fillets completed as well - those will be from light 1/16th sheet.

Nice looking bones...this is a really intriguing airplane.  The history of this craft is interesting if you haven't looked it up! And I believe that there's a replica built from the original in the EAA museum as well.  Here's Wikipedia's info: Click Here

EDIT:  Did some further research and found out the replica crashed killing the builder/pilot on what was to be the last flight before being donated to a museum.   Embarrassed Really sorry to hear this!

I will fill the removable section with balsa and carve to shape.  Once properly fitted, I'll add 1/8th balsa to the ends and bottom to give me 'trim area' when fitting the canopy.

I cleared out a bunch of interior mass  Smiley and I have started to build my canopy plug.  I also built the front V-tail mount former.

My top formers and top keel are working out well.  There will be a large vacuum formed canopy, but it is a very basic curve so it should go well.  (I still have not successfully made a canopy for my Nemesis which is all that is needed to finish her  Angry).  Current weight is ~10 grams.  I'm hoping to reduce that a bit by cutting out some of the intermediate 'scaffolding' soon.
