One aircraft was a Cessna and the other a Liberty. From the very limited screening of the Liberty on TV, it seems it was relatively undamaged having landed safely. It appears the Liberty cut through the rear of the fuselage of the Cessna dislodging the tailplane with inevitable consequences. All this subject to correction - source of information TV only at this stage. On a more pleasant note, I spoke to a chap at the service station this afternoon when I noted he was transporting a gyrocopter on the back of his Toyota utility. He was on his way home after having the aircraft completely serviced and he told me that his 912 ULS engine has done 5200 hrs and it has just been fitted with a new set of rings. If the figure is accurate, I think that is an incredibly life given he is a professional cattle musterer flying low in hot, dusty conditions etc. Is this not testimony to the longevity of the little Rotax engines? Previous to this, I have heard of another 912S doing 3500 hrs virtually untouched under similar conditions.

From: grroberts3@juno.com I went solar with mine. Of course, it helps if your in Arizonia in July. I peaked at 160, and held 130 for over 8 hours.

Today we built ourselves an "oven" for baking our parts at the appropriate 40-50 degree celsius for post cure. We built a 16' X 4' X 4' enclosure out of foil claded 4X8 sheets of insulation foam. The box is backed up to a basement brick fireplace (no open flames) in which I would like to place a suitable heating element. I also have use of an attic fan to low air around the cavity. Has anybody attempted this before? And if so what did you use to heat the space. I went to a website that helps you calculate the heating requirements for 256 cubic feet of space @ 50 degrees celsius came to about 8900 btu's, however, heat does build up and I want a consistent heat over a period of hours therefore I will need a thermostat of sorts I would guess. Any advice out there? I'm not a thermo engineer just an individual Europa builder who's looking for an inexpensive way to do the job. Thank you for your time and consideration.

Be careful. The surface temperature and the air temperature, even only a couple of millimetres away, can be very different. In motor racing you often see a 10 degree C difference between air and track temperatures. In the UK I imagine you can easily see a surface temperature of a wing left in the sun being over 40 C. Anyway I cured my surfaces in the open on a hot July couple of days and I'm still here. Perhaps someone has some accurate figures?

From: "rparigoris" Hi Jeff We post cured in a sausage: http://www.europaowners.org/modules.php?set_albumName=album213&op=modload&name=gallery&file=index&include=view_album.php It rolls up to a small bundle when not in use, it is not anywhere near as insulated as a piece of insulation, but not bad with a blanket of bubble wrap draped over the top. We have a muffin fan that keeps it inflated and a zipper to enter, and 2 thin aluminium poles to keep erected when you open the zipper. Using at least one 1500 watt resistive heater that articulates (has a fan inside). Needed to mutilate the thermostat and recalibrate and put in a higher temperature thermal fuse. Can't remember if that higher temperature fuse is a "piece of safety wire", or had a thermal fuse on hand. I think I had a copier thermal fuse I used. This works well in summer. If it's cool out, needed is a second heater, a cheap resistive oil heater from Lowes or Home Depot works well, again you need to mutilate. Just keep in mind that those oil heaters can leak. Never had one leak in post cure tent, but unmutilated sample that keeps edge off cold in our build tent when we are not there did in fact leak. Plan for a leak if you use one. Typical they have a few heat settings. Like others indicated, sample plenty of areas, you don't want to hurt anything. Good idea to clamp aluminium angle to trail edge of anti-servo tabs, stabilators, ailerons and flaps to prevent waves. I think 1500 watts is fine for you. We slowly ramped up temperatures, and slowly ramped down. At post cure time I had some reason for that, but forgot why. Wayne took to bathtub and scrubbed real hard with plenty hot water and plain old green Palmolive to remove any blush, finger prints and other?? Best handle with cotton gloves after wash, post cure and fill right away. http://www.europaowners.org/modules.php?set_albumName=album219&op=modload&name=gallery&file=index&include=view_album.php Ron Parigoris Visit - www.EuropaOwners.org ________________________________ Message 6 _____________________________________ Time: 07:05:36 PM PST US Subject: Re: Europa-List: A question about post curing?

So tell me guys...is everyone post-curing BEFORE filling? I seem to recall a thread where post-curing was recommended AFTER filling...but perhaps I'm mistaken.
