Ultracote strength - single sheet or pieces OK?

I'm about to start covering a M60. I'd like to put fore-aft stripes on the bottom for orientation. This is my first real experience with using Ultracote. Do I have to use one continous spanwise sheet and then apply strips of contrasting color over that? Or can I stitch dicrete pieces together with some overlap? Does it matter in terms of strength? TIA

You can use seperate pieces; just overlap them about 1/4".

What are you useing for the fuse? Im planning on useing Solartex for my M60 as it compund curves well. But I also found out that Ultra does aswell. Good pick on the Ultra, its the toughest one out there!

It'll probably be easier to just lay a whole sheet at once and then trim stripe as necessary. That's the way I usually do it if I have the materiel. If I'm trying to make it stretch then I would do bits at a time.

Just my .02

Use separate pieces like stated in Pete's answer. I find that you get a cleaner look. If you lay a 2nd piece over another it tends to get bubbles in it when you apply the iron or heat gun.

When you guys are talkin' "Ultracote" are you referring to Top Flite Ultracote (aka Heavy Duty Monocote) or Hanger 9 'Ultracote'??

Who's supplying the Hanger 9 Ultracote online? I've found a few places but their stock seems spotty.

Hanger 9 Ultracote. Monokote is a high temp covering...great for open structures but may melt foam when you apply.

As far as strength, I would think that one piece is stronger...how much so and wheter or not it will make a noticeable difference is debatable. I prefer the "Schiess" method . Saves on material and you don't need to worry as much about keeping your covering in a dark over light colors order.

NICE Weasel!

I don't have any personal opinions about the strength issue, but I distinctly recall that my M60 instructions said to use one piece of Ultracote for the wings (i.e., don't cut the covering off the part of the wing that goes into the fuse) in order to retain the strength of the covering. The instructions said that the wings get additional strength from the covering.

I laid down my yellow top and bottom and then added the purple stripes. Beware that if you do this in reverse order, the darker color ultracote will show through the lighter part (i.e., you will see the purple through the yellow).

The overlap is pretty strong if at least 1/4" like Pete said. I also try to wipe down where I'm going to make a seam with alcohol to get off all my finger & hand print mung before ironing the overlap.

Thanks Dom!

I'd say that if the instructions call for a solid piece, you'd be wise to consider the solid piece.

Under 11.5 ounces...it was about 11 and change right before final balance and took less than 1/4 ounce to get it dialed. I haven't weighed it since it was cg'ed. Has a balsa tail, but it's not exactly a light tail! LOL!

Another option is to use a single piece of iron-on and then apply trim using sign-writing vinyl or the like.

either way will work really. just stick to the basic rule of thumb, light colors ALWAYS first.

The ideal methodology is to use one piece of Ultracote on the top of the wing and one on the bottom of the wing. This will give you the optimum torsional rigidity over EPP for the wing.

The other reason for using one piece is that when using the proper Ultracoat shrinking technique you will allow yourself the ability to modify the shape of the wing with more consistency. i.e. should you want to increase or decrease the dihedral of the wing.
