I've made a "prototype" just to see if my parachute could slow down the plane enough to not crash.
It looks very ugly. But just for proof of concept. It's positioned near the CG a bit back though so it wouldn't entirely fall flat and possibly tip-stall. As a release I used a bomb drop mechanism. Haven't tested it out on the field yet because the weather is very bad...

Hehe 
Not that big. If fully stretched about a 1.5x0.5 meter. I chose this plane because I don't have a 200g profile foamie and because this plane is a very good floater. It can fly flat down(and land... It's a bit rough though) with full elevator without changing the CG.So it doesn't need a lot of slowing down... Also the plane is about 1x1meters.

oh very nice! im eager to see it.
this all got me thinking about how i could place separate parachutes inside some of my model rockets so i browsed around and picked up a pack of these:

they are just small enough to fit into a 25mm tube and have a great, solid density to them to fall relatively quickly. and plus, if i lose it, they price to only $.50 each so no harm done! just looking for a calm-wind day to send them up. i was also thinking they would work great in a bomb bay hatch like mikeysrc designed. You would probably be able to fit all 12 in something like that.

So here's the video.
I should mention that there were strong gusts so I wasn't able to fly very stable. Also first 3 flights were unsuccesful, the parachute either didn't deploy or deployed when I wasn't expecting. 4th flight was the best but you can't see the landing very well on the camera. It was quite dark...

It seems to be more of a challenge to make the parachute deploy the way you want it.
I guess that will have to have a closer look at when you will deploy the parachute. Or even better at which position related to the ground your plane is so that the parachute can only deploy correctly, if you know what I mean.

If the flitetest guys would want to do a challenge episode I could tell them some tips and what not to do.
Also to make the parachute better I'd need some bigger rubber bands because these ones somehow get tangled in and not release the chute. The 2nd thing is maybe a piece of paper or something that would cause drag, I'd attach that to the top of the chute and it would help deploying it quicker
