Composite Accelerator


I have been missing my K&A Models Accelerator so much, that I finally got motivated to do something about it...

I got a heavier lay up fuse from Ken (the standard one is EXTREMELY light) a while back, so I thought a bagged wing and tail would be better than the balsa slab tail and balsa sheeted wing. And besides, some uni-carbon and Kevlar was collecting dust.

Here is the photo essay-
Without describing everything, just buy the DVD set from Phil Barnes and Bill Hayman, and you will be able to do all this easily.

First 5 pics:
Tail
Tail
Wing Core
Carbon Skin with hinge slots
felts for breather

And the next 5 :

Warm up the epoxy,
lay down the glass on the mylars,
add exotic cloth,
put the mylars on the core,
into the peel ply/breather, and the v-bag itself.

Truer words were never spoken! Without that DVD I doubt I'd have ever bagged anything.

Looks like a great project, Target.

And the next 5:

Back into the beds,
Add weights,
use the ugly home made vacuum device,
apply 18-20" of vac,
And, don't forget HEAT!

Hey, it's a wing!(In the rough)

Thanks, Reed!
Now, instead of shaping my LE (like I should be doing), I have to go eat Sushi with the family...

Target,
The wing looks great. Is that a one piece wing or did you juxtapose the halves for the pixture?

Hey Surfimp, if you're still trying to decide on how to do up you Fauxdent(sp?) wings take a look at the finish that vacuum bagging yields. It realy isn't as hard as it seems.

Harry-
The wing is one piece; I wanted to get some strength, and simplicity.
Thanks for the compliments from the rest, I wish I didn't have to work so much this weekend!
I'll post some more pics later, the fuse should be pretty brawny, but not too heavy when done. I'm shooting for around 24oz AUW on the plane.
JD-
Best money you'll ever spend; even if you never bag a wing, the DVD teaches you how to think about using the fabrics.

Looks terrific!! Awesome work Target!! Tina was supposed to call you to help her get me the Accelorator for Christmas, not that it was a suprise..... but a last minute change to buy a Jet 12" Bandsaw evolved. Im gonna kick myself in the booty when I see that plane of yours. I was really lookin forward to getting one, now Im just lookin forward!!

A simple but necessary item:
Take note of the paper plate under Target's hardener cans: you'll want to have that set up to catch the goo that seems to self pump out (is it due to barometric pressure changes) on a intermittent, but regular basis. It sure can make a sticky mess otherwise! That and always wear some gloves when playing with epoxy. Sensitization can happen when you least expect it.

Yep, I've seen Richter's bagged wing planes, as well as a few others. Verry nice! But I still like wood & glass. It's (obviously) not a rational thing. Just gotta learn the hard way, ya know?

The irony is that I will be using a vacuum bag to sheet the wings. I know, so close, why not just do the full deal...hehe. Why ask why?

Target, looking good! I am taking notes!
