Goodmorning, Thank you. Yes these kits are a lot of work. But if you take your time and just study a point in construction that confuses you you will at some point come up with a solutation. Anyhow that is how I build, reach a tought point, look at it and then walk away and think about it.

Here is a pointer for those of you who are building a 1/3 scale Waco, may work on the 1/4 scale as well. At the point on the firewall where the upper and lower longerons meet, I put a wood (servo) screw horizontaly at all for corners(through the upper and lower longerons and the upper and lower cross braces). I then ran four screws through the front of the firewall on the upper and lower cross braces. The reason I did this is the firewall is kind of thin and I'm useing a very powerful and heavy engine RCS 215 Radial. Just some back up strength. Also. where the drag wire posts come throug the lower longeron I put 3mm plywood on both the fron and back side as this post just goes through the balsa. This gives much better support for that part when you tighten up the nuts.

I am also forgoing the counter weights on the lower wing as I have one 255oz/torque servo in each bottom wing. Those counter weights are supposed to counter any flutter you might get in the alerions. But If you are useing a smaller servo you may want to use them. or 4 servos(one each wing) you can also delete them.
If i get flutter with a 255oz servo It will be just a fraction of a second before the wings come off.

Anyhow now off to work.

Steve
