Hi,

Something to consider between the two systems is honeycombing. If you're going to do honeycombing on the cores the vacuum bagging may not be appropriate.

I used vacuum bagging on a set of Stylus wings and tail cores recently and it worked great. Very easy to use. There are a few good videos on how to do it on the web too. I used Bolly general purpose epoxy which is very easy to work with and gives you a good working time. BTW with vacuum bagging you'll be amazed at how little adhesive you need! The vacuum also provides far greater and more uniform pressure all over the wing. Be careful not to use too much pressure or you'll crush the wing! Try doing that with bricks etc.. lol

For the bags I used plastic pallet covers cut down to size and re-sealed with a sealer/welder.

Cheers
Jason.
