Craftsmanship like this is what inspires the rest of us! Truly amazing work and follow through. Imagine the feeling you are going to have when it all comes together and it flys for the first time. Good luck with the rest of the build.

I put horizontal stab ver. 2.0 in the vacuum bag this morning and have all the internal guts ready to join it this evening. Tomorrow afternoon I'll have a 2nd (hopefully much lighter) stab half..

Horizontal stab Version 2.0 has its skins cured and in the garbage!
both skins ready to join came out to 12.3oz, with the addition of the internal structure and the pivot shaft, they would of ended up at 1.2lbs total weight. Lighter, but not enough! Next step, is to get some thinner core material, and some lighter weight carbon (the stuff is $198 for 1 square yard! OUCH!) I may also try a layup with very little carbon compared to what I have been doing and just go with an extra layer of glass. If tomorrow is to windy to get some flying in, I will layup another horizontal stab. The plus side to all of this, is that once I figure it out, i'll know what needs to be done for the entire tail section of the airplane. It sucks to waste the material, but it doesn't hurt to much considering the core and carbon I have was purchased on sale for a very significant discount. |

Yea the learning curve sucks.. and is expensive! What really sucks, is once I get past the learning curve on the tail parts, i've then got to go through it with the wings... Oh, and then there is the REALLY steep learning curve of the fuselage and vacuum infusion!

All of the door and speed brake molds. I used some surface resin and some epoxy tooling dough to make these. Much easier and faster than doing glass layups. It took all of about 2 hours to do all of these molds..
And the right H. stab mold is closed up and curing. should have the first Pair of H. stabs tomorrow.. I also ordered some contest grade balsa sheets to try in the vertical stab layups. I'm also thinking of offering nose and cockpit "display" sections (both kit and completed) for those who want a cool display to build up some funds to keep this project moving along.. |

And then there were two....

While these are heavier than i'd like (1 pound, instead of around 3/4 of a pound), I'm tired of wasting materials and time on parts that are essentially trash. These will be kept and ultimately flown on the prototype. They have proven to be the learning exercise i didn't expect to get, but the production parts will be lighter.

I have CAD drawings for them, but other than that, i have done nothing else with them. The armament is not really a priority unless i get enough people interested in some of the stuff for their FEJ models.

No progress. I have been busy with work, family and trying to find a machinist
