Balsa wood for motor mounts


I'm a care bear...Really?
I'm in the process of building a blue foam/dtfb A-10. I need to find the type or close to the balsa wood the flight test guys use. Should I use the "plywood" stuff they use or should I look/use a thicker balsa wood for my motor mount design?

plywood has the advantages of the grain going in multiple directions gives it much greater strength, and as lonewolf said, balsa wood is just too soft, and your motor mount will be having a bunch of forces acting upon it, so you want the best strength you can get


More combat please...
Your local hobby shop will have what you need.
My foamboard and corplast planes are sporting paint sticks from home depot. Free is good.

I use coroplast for my firewalls. You can buy sheets of it from your local hardware store. Works great, super strong, and holds screws perfectly.


There is an episode of Flitetest where Chad flies a plane made of coroplast:

I found my plywood at Michaels...I think it is definitely a little thick for the control horns but really nice for the firewalls. I think the thickness is 3/32" maybe 1/8"
