Scale Curtiss XP-55 Ascender

Once you have the plug in the parting board and you are happy with where it's sitting then you need to seal the edges with clay. I use a plastic putty knife to get a nice sharp corner along the edge where the plug meets the parting board. Don't worry if you have a bit of a gap between the pug and parting board, the clay will take care of this, of course the better the fit, the less clay you need.

Once you are at this point, then it's time to start with the actual mold making.
Until the next session,

Here is the story Ace, I ended up missing first place by just 1.6 points, if Brenda had not missed calling the loop in my first round I would have won first place in designer scale, it figures this was the first time she ever missed calling a maneuver & she feels awful about it, oh well:(
My first round I was flying in front of the "generous" judges so my scores were a notch above all the other rounds so to miss the opportunity during the first round killed us. I thought my flying was the worst during the first round but I was getting the highest scores for my flying, it just goes to show how much difference the set of judges can make. The last round on Sunday I had some crud in the carb and the mixture would not go rich, something I check prior to each flight, I took off anyway and the engine started to go lean so I called a "mayday" and landed without incident. If I had scored better than a 92 on that last flight I could have won again but it was not to be.
I did get the highest static score yet with my Fiat so that was a good thing that came out of this event.

Now for some updates on the Ascender project, today I was able to cut the old fuse apart and salvage the wood formers that form the nose gear mount and the servo mounts. This little assembly came out perfect and cleaned up great, all I have to do is slip it in the nose and glass it in place, this saved a huge amount of work and I know that everything already fits! Also finished glassing in the mount for the electric motor, and cut the cowl flaps in the tail end. Here are a few photo's of the work so far, oh yea, the last photo is of the hatch on top of the nose. I am really happy with the fit of the hatch:)

Today was a good bit of progress, I got the canard bearing former epoxied in place. It was a challenge to get it all square and true but I came up with an easy method. I used a rubber band to keep the stick pulled up against the inside of the nose, and with slow cure epoxy I could take the time to get it right. After it cures over night I'll glass it in place.
