Status: offline 		After much waffling I've finally got an approved Q40 design based on Mike Arnolds AR-6 Endeavor..

To start with, the plug will be made with formers and foam.. Assuming everything goes well I'll look at an aluminum mold at a later date.. I'm doing a couple different wings to try before moving forward with a wing mold..

I sent the DXF file out to the laser cutter last night so hopefully next week I'll have some pics of the build..

A special thanks to Gary CAD work, it turned out way better than I could have hoped..

I sent off the material to the laser cutter but it doesn't sound like I'll get it back until Monday next week.. I'm going to try and get all the foam pieces ready and stabs done before then..

I'm trying to decide if I should do a removable horizontal stab or not.. Any thoughts?

I posted something on Scott's page and realized I hadn't given you any props. I applaud your efforts. LOOKS GREAT!

As Dave pointed out it is going to be fun to see the work that you guys do. Having done it (a couple of times) I can't wait to see the progress. I guess the race is on.

Yes, Scott has reminded me that Invictus beat the Endeavor at the last race in Reno.. I assured him that wouldn't happen again..

OH yeah, I almost forgot. I found a picture you might enjoy....

Seems to inspire me!

Does anyone have a suggestion for a good laser cutting place that won't charge me my first born?

Status: online 		I use Fun-Aero in South Carolina. (803)499-5487 and ask for Jan. (Jan & Mike Bell are the owners) They charge $30.00 Hr. + actual wood prices and are very good. (1 hour of laser cutting time is a LOT of parts!!) As long as you have the parts laid out for the cutter, it is just an email away from being done. Jan has been cutting parts for me for 10 years now, and is a great person too.

If you need any help with the files, let me know Lee; I will be happy to help you out.

Status: online 		Yes, they can use .dwg or .dxf format. I think they use AutoCad 2000, so you want to make sure they are 2000 or earlier format. Red is cut, green is engrave for their laser. Call Jan and she will talk you thru it, she is a great person.

Status: offline 		I finished up the V-stab last night.. It's amazing how much time it takes to cut pieces by hand.. I didn't think it would take me more than an hour to do the Vstab but it took me quite a bit longer.. Most of the time was spent trying to account for how the Hstab was going to be positioned and how it would flow into the Vstab..

I finally have my formers coming.. I had to pay but it was very reasonable and I will have them this week.. It was so much cheaper than I expected I might even have them shipped next day air..

Status: offline 		I got all my foam pre-cut into strips.. If you notice in the first post, the fuse is disected every half inch.. I cut some Dow foam into 2" x .5" strips so I can just trim them to shape as I go.. Hopefully there will be all sorts of foam dust in the workshop this weekend with pics to come..

Status: offline 		After much screwing around I'm finally ready to start.. In the pic you can see the laser cut formers, the square shaft and the foam.. I don't think I have 5min enough epoxy, might have to make a run to the hardware store before it's all done..

Status: offline 		Hey Lee:

Keep an eye on that spacing, like we talked about. The templates were made for 0.5000 spacing and if the foam PLUS the template material PLUS the glue is thicker or thinner than that, the tolerances are going to add up. Put marks on the tube to insure that you are staying lined up, otherwise the plug won't come out the correct length.
