    I already have the plane out of the jig but I'm also building a new Dalton Mel for Brendan Jones and a Mel for Dr.Greg Baggerly. So really I'm building three planes at once. I'll try to pick up the pace. What you've seen so far I did in one day.

    Now that you have glued the motor box together and the tail section together, we are ready to glue them to the top rails. DON'T FORGET, these planes are built upside down. So what you need to do next is to take both bass wood stringers and lay them on the plans as noted. I try to stagger the glue joints in the two stringers so they're not in the same part of the fuse. Take some T-pins and secure the rails in place. Then take the motor box and set it in place on the plans. Do the same with the tail section. Each former has a center mark so you know the fuse is straight.Once you have a good fit on the tail section and motor box, glue these to the rails at this time.

    Next we will glue each former in place. You can start from the back or the front, it doesn't matter. Each former as I stated before has a center mark lasered in. The plans also have a center mark all the way from front to back. At this time glue each former to the rails in it's proper place. You should get a tight fit to the rail right at the point on the plans, if not check to make sure the rails didn't move. Remember to check your center line.

    Next we will install the FS-2 sid formers. These serve two purposes. The smaller hole is for the wing bolt and the front hole is for your servo wires coming in from the wing. The root cap of the wing has the same hole for the wires so all you need to do is make your channel in the foam wing for the wires. All the guess work has been taken out. These two formers can only be glued in one way so you can't glue them in wrong. Glues these in at this time.

    I may have missed it, but what glue do you use when you're gluing the plywood formers and hardwood longerons together?

    I use Titebond for almost everything wood related but I did state earlier that if you like CA than use what you are comfortable with.

    How come you have an arch on some of the formers?

    Great build, what is the target wieght on your airframes?

    I really like the ability to get some of the foam parts already pre-sheeted. I would want to build my own 40% but that part bothers me because the plane hinges on those being perfect, among other aspects. Great idea and addition to the consumer.

    Its a great option. I know for a few extra dollars, it worth it.

    The prototype came in at 40 lbs 6 ozs. The sheeting was a little heavy for my taste so this one should be around 39 lbs. That's the weight I'm shooting for with out any lightening mods to the wings or stabs

    Rob, I didn't ask this earlier, but do you have a baseline price on the kit?
