@Off-topic jes how did I miss this!? following!

Well the wings I’m either gonna do the ribs out of foam or I’m just gonna use foam core

Thanks

I need to save up some more money to get the balsa for the tale surfaces so I’ll probably be posting next week or later this week!😄😁

I’ve been thinking should I build My tail surfaces out of foam and then do the leading edges out of hardbalsa

You want as little weight in the tail as possible. I found that out the hard way......

 

[Off-topic jes]

So foam or no moam?

I did this on my Fledgling. I used FB with the paper stripped off. 3/16" balsa sq. went around the edges and then I sheeted this one with 1/32" balsa. For 1/4 scale, I would recommend using 1/16" for the sheeting & maybe make weight savers like I did in the second example shown. You'll find that for the materials used, the weight will be fine. It's the glue that gets soaked onto the balsa that adds the weight hence the weight saving holes means less area for glue. Never did it like this for that size, but I would think that with the balsa sheeting, It would end up being pretty strong.

So between the wing on your Bee and what you just shared here I think my brain might just explodeThanks for opening some new doors. think I can put this stuff to some really good use.

Just a little experiment I genuinely think with quite a bit of sanding this could work looks pretty good it’s extremely light obviously I would reinforce it with hard bossa and spruce or maybe just fiberglass it

Looking good! Your moving right along on this one.

Is that EPS foam (foamular)? If so it is plenty strong if you laminate it. If you don't laminate it, it cracks easily.

 

[Off-topic jes]

No it’s just normal construction foam

 

[Tench745]

No it’s just normal construction foam

Foamular is a brand of construction foam, but the abbreviation for it is XPS. EPS is the white bead-foam.

 

[Off-topic jes]

Oh cool

 

[Off-topic jes]

Would this work for my cessna? I’m asking you cyclone

 

[Off-topic jes]

Or anyone
