Thanks.
Do a search. There are lots of easy to use CAD file readers free on the web, and lots of good info right here on RCG of how to take these files and convert them into PDFs of any size or scale you want.

Fuselage weight


Can anyone tell me what their Yardbird fuselage weighs all up ready to fly with radio gear installed and fin-rudder (not stab)? I'm trying to get a feel for the ball park to hit with the wooden designs.

Thanks.

This may not be what you are looking for, but my balsa pod/boom e-fuselage is 22.5 ozs without the flight battery. 26 ozs with the flight battery. The removable stab/elevator is 2 ozs including the nylon bolts and hinges.

Thanks Dion9146. If it's not too much trouble, can you tell me the weight of your Yardbird wing?

Anyone have a non-wood pod and boom or glass fuselage weight?

Thanks.

25 ozs and that is with micro servos attached to both spoilers. I did not use the string pull method due to limited space in the fuselage.

I may have an old version but I don't see in my plans or instructions about the extra forward carbon spar inside the sheeting. Am I missing something or is the 2nd spar optional?

The second spar was of no advantage so I never added it to the plan...

Well I thought it was pretty a creative method anyway, especially sanding down the spar bump at the end.

I am at a loss as to where to buy the wing joiners. Could someone tell me where they got theirs? If someone has some bent I would buy it from them.

I used K&S aluminum rod (3/8" dia?) sized to fit in a corresponding brass receiver tube. However, I had to sand it down since it was slightly oversized relative to ID of brass. Chuck it up in a drill press if you have one, and sand with fine emory paper.

Bending is relatively easy--three steel rods and the Al rod in a bench vise. AL rod goes horiz in jaws, other three vertically. One rod goes across one side at the center of the rod you want to bend, and the two on the other side at ends of vise jaws. Crank on vise and you bend the rod at the center until you reach the desired angle. Hardest part is keeping all four rods in place as you crank--you might be able to make a jig by drilling holes in a stick. You can probably find a picture on the internet to back up my poor description.

I bought mine from a surplus metal company on eBay. I also purchased 1/2" aluminum rod for my full house Hawk wings from the same supplier. Something like $5 for 3 feet of 7075 bar stock, but I also had to sand it down slightly to fit in the brass receiver tubes.
