I have a mate who destroyed his Wind 50 and he gave me his wings virtually undamaged. His wasn't yellow and black so I am going to strip the covering and recover it but I might use Monocoat black. Good luck with Modelflight. As I said nice guys to buy things off but when it comes to warranty claims it may be a different ball game.

I was going to buy a yellow and black PC21 but luckily I could not find one so bought a red and white one instead. I find black and yellow easy to see.

Yep, that's exactly what I was thinking. Thanks for the pics!

Avoid black Oracover?!

Seems my peeling clear is a common issue with black Oracover....

Update on my covering issue.

Modelflight are replacing the wings - will be in next shipment from Sebart - at no cost. Good outcome.

Might try to strip off the clear on the current ones for now, and possibly seal the black edges in clear film when the relpacements arrive.

Interesting to see if the new L wing still has a gap at the root T/E too...

Good one Cam. The next shipment is due in three or four months I think.

Looks like a 2 1/4" (57mm) spinner...

The fact the thread above started in March 2013 does not indicate that manufacturers like Hanger 9 (my Meridian) and Sebart (my Wind 50) took the matter seriously then and still foisted defective planes on their customers a year later.

It couldn't have been that widespread, of my 9 Sebart planes over the years, 5 had black and I've never seen the delamination first-hand. I do know it happens, I've seen it in pictures of more than black too, but I'm not sure it was a conspiracy. Reputable manufacturers (which I think Sebart is) don't really want to push out defective products IMO, it's bad marketing and bad for future business for sure...

And one can not know for sure how long an ARF, from Sebart or others, has been on the "shelf" efter it was made by the actual ARF company the covered the plane. And maybe not so easy to know if roll(s) of Oracover (Ultracote) has some defect when they cover the planes and if the rolls they use are of "suspect" quality. For example the Sebart plane camdyson has. I suppose Modelflight can trace when they got the batch of Sebart planes that camdyson bought and then it can be traced back in time when it was made at ARF factory.
If I remember correct on Sebart planes it should be a small label on fuselage and wings that it was quality checked and by whom (and possibly a date when it was quality checked).
I was thinking maybe black film in general could have a tendency to get lift of the clear layer in very hot temperatures? Maybe that is contributing to a problem like this? camdyson live in Australia so maybe rather hot where he lives?
I think the important thing is that when a covering problem like this occur the manufacturer stands behind the product and and replace defective (covered) parts on warranty and in this case they did, new wings för camdyson.
I suppose it could be same problem with Ultracote since it is Oracover, just other name on the US market. Oracover/Ultracote is made in Germany by Lanitz-Prena Folien Factory GmbH. So maybe it is common problem also on Hangar 9, Extreme Flight etc planes that use also Ultracote?
But most likely it was bad quality Oracover/Ultracote that was released some time that is the real cause for the clear layer to separate. There has been cases where some ARF manufacturer was suppose to have used Oracover but instead used som "copy" of it (sample film from such planes had been sent to Oracover that analized the film and they said it was not genuine Oracover).
http://www.flyinggiants.com/forums/s...6&postcount=42
I'm not saying it is the case here but given the rather high cost of Oracover it could be tempting for any ARF maker to use a cheaper Oracover copy.
I have 4 Sebart planes, bought 4, 3, 2 years and 6 months ago and none has clear layer problem on the Oracover film. I have no doubt they are covered with genuine Oracover.

Wind was already in the air so it is not crucial for flying , but I'm just curious:
Did you removed areas in bulkhead? (See attached photography, there is arrow pointed to one of them). I didn't found any notice in manual, but it can means Sebart just forget mention about it (similar to servo covers on wings).

Hi,

On my Wind S 50E I have the plywood parts still in the firewall. I Think it does not matter if it is still in place in electric powered option. For glow powered option it must be in place ( and whole engine compartment fuelprofed). In my case, I use electric motor, and I have one thin layer of epoxy in the motor compartment area so it is waterprofed and also in the firewall parts I had a little extra epoxy so it was like glueing them to the main firewall.

I think Sebart think one can remove the plywood parts in the firewall when electric motor is used for some extra cooling air to enter the fuselage. But as I said it is in most cases not neccessary (at least if has worked fine for me in hundreds of flights, also in very hot summer days).
