Hi John,
Yep we are going to be busy, when we pick up the kits from Cam he plans on showing us some of the fixtures he has come up with to speed up the fuse side builds. Maybe we'll come up with a few more tools and processes as well.

The quality of the wood is sensational, all of the ply parts are made from real aircraft ply from Wicks Aircraft.

The fuse and turtle deck sheeting is "A" grain so the grain lines are parallel to the sheet so they form well around curves. All of the sheeting has also been edge trued.

We spent a few hours going over the plans with Cam, making sure we were all on the same page with the construction of the kits. Right now the there is no instruction book, Ron and I are building the first ones and this thread will act to support a build manual that Ty Lyman will be authoring, Ty, your kit is on the way, Cam had your wood parts boxed and a ready to ship to you today.

Next we dry assembled a motor box, everything fit right in place, the ply is awesome and a real nice feature is that were each piece fit together in it's tabs and slots meat, at each their four corners there is a small radius relive so that the glue truly locks everything in place. This will become more evident as we get into the build process.

As mentioned Ron and I have four kits, one kit is being built for John Sabini of New York, his will be powered by a DA 150. The other kit is for Jerry Unruh on California and will be powered by a DA 200. The motor boxes as they come have firewall locations for both 2 and 4 cylinder engines.

The other two kit's will be built and are available, just let Cam or us know and they could be yours......

Ron and I are really looking forward to this build and we hope you can follow along with us. These will be great IMAC machines!!

Now for a little trivia, (last three pictures) Ron and I in the past few weeks to keep busy are building a kit for a customer that was started about 20 years ago. I was going to build the whole kit for him, but he started and framed up the wings. He went away for last 20 years and he has just returned so I asked him if he wanted the kit completed. He did so this is what we have been doing for the past few weeks. We made some modifications to the kit so canisters can be used and we planned off the very blunt leading edge and added a new one that should allow better snap performance.

We of course know the kit manufacture, but wondering how many of you recognize this kit. Some details, Extra 300L, 104" wing span, fixed (non-tube) tail group.

Ohio RC is what the 20 year build looks like.

Awesome. Can't wait to see the build on the KAM Aero. I'm wanting to make this my next plane.

Yes! I'm going to love following along here! Pleasure to make your acquaintance Keith! I will be building one starting in mid to late December. I'm in the Cleveland area (south). We are moving into a new house the same time.

Hey Tom, great to see this get started.
When you glue the motor box together, will you have it assembled and apply the adhesive to the outside of the joints or apply glue in the joints as you assemble it?
What type or brand of adhesive will you use?
Is that a drawing supplied with the kit that I see on the table under the motor box?

Steve,

We will use a mix of Titebond II and Zpoxy for the motor box. The firewall, landing gear plate along with the 1/2" x 1/2" oak reinforcement rails will be all glued in place with Zpoxy. All of the rest of the motor box will be glued in place with Titebond II. We will apply the glue in the joints as we assemble, once everything is in place and clamped were needed we use "acid" brushes to clean up the joints. If you look at this close up photo you can see at each of the four corners of the tab and slots there is a small radius relief that allows the glue to roll into the joint. That is a real cool addition to make sure everything is totally secured.

Yep, that's one of the two drawings that come with the kit. The drawing are excellent and included both a fuse left and right side drawing, greatly lessens the possibility of making two of the same side....

Another nice feature is that each drawing has a important note at the top that gives the real overall dimension of the fuse side length witch I believe is 83". This is done because even though the drawing are printed on a plotter by a professional drafting print house, there can be some minor differences between drawing just because the paper can shrink or stretch a bit. So before you start the build, measure the fuse sides on the drawing and make sure it's 83", they all should be, but just check to make sure.

We are not building today, Ron is helping our friend who owns a local hobby shop. Tomorrow we will have a shorten day as one of our flying buddies, Ken, is moving to Florida and we are attending a good by lunch.

I am not sure I totally agree with the relief cutouts as a feature and more of a necessary evil if you use a router. With those I almost think I would go for some form of epoxy rather than titebond to fill that gap.

I would still bet that the joints will fail long after the wood itself fails so probably a mute point.

Keith,

You are right about the relief cutouts being necessary because of using the round bit of an CNC router vs. laser cut. The last 25 or more kits I have been were laser cut, square corners, it's been a while since building a router cut kit.

In terms of Titebond II vs. epoxy, everything I have been able find about comparing the two, Titebond II has a tinsel strength about 3700 psi, and that's higher than most epoxy's south of the expensive true aviation and marine like West System and Aeropoxy where their tinsel strength runs in the 10 to 12,000 psi. range.

We are still not totally set as to witch adhesive we will use, but you are right again, ether will provide a very strong airframe and the joints will outlast the wood....
