Ultracote - much easier to shrink and goes around curves with no problem. I especially like their Parklite.

I've only experience with monokote but it is a bear to work around curves. Also I suck at cutting a straight line even with a straight edge.

For me Ultracote is easier to work with. But it costs more and is only 24 inches wide, while Monocote is 26 inches wide. Depending on the size of your model, that extra 2 inches of width can make a difference.

Ultracote is not as strong as Monocote and is much more likely to flutter. Your choice: ease of construfction or ease of destruction.

Ultra - shrinks like crazy, but won't stretch.
Mono - doesn't shrink as much, but will stretch.

Ultra - glue is mediocre, hard to keep it stuck down
Mono - better glue, narrow trim bits stay down better

Ultra - often goes slack/ripply in the hot sun
Mono - tends to stay shrunk better long term

Ultra - keep heatguns away from seams or they'll pull loose
Mono - you can burn through it with a heat gun before the seams pull

Ultra - easier for a novice to produce a presentable result.
Mono - harder for novices to work with.

That being said, today's Monokote isn't nearly as good as it was 30 years ago. I had some planes I built in high school back in the 70's stored in hot attics and the Monokote on them was tight and still stuck when I took them down decades later. I rather doubt today's product would withstand that kind of test.

You can get a decent result with either product. Each has multiple shortcomings and multiple strengths.

I just started covering a newly-built, vintage Sterling Lancer SL-62. It has some funny curves that Monokote didn't like. Ultracote went smoothly without a single wrinkle.

I'm slowly but surely moving to Ultracote/Oracover.

They are both good coverings and both have their positives and negatives. I prefer Monokote but it does requires a bit more skill to apply. I only say this because Ultracote and be put on the frame wrinkles and all, and shrunk tight. Monokote has to be put on wrinkle free before you even think about shrinking it. I have been using Monokote since the 80's and have not noticed this big change in formula everyone is talking about. I have only covered 2 planes with Ultracote and decided I like Mono better. Hobbico/great planes/top flite/Monokote could do a better job of showing people how to use their product. They do sell a DVD that is ok, but I think they would be better off videoing a ARF worker using their product. As much as I love Mono, it is a pain to apply Mono over Mono without punching holes on the base coat. I look at ARFs covered with Mono and there are no bubbles or holes punched in the base covering. I wonder how the heck they do that? I am covering a Peter Rake Fokker DVII with Mono right now and covered the nose block with one piece of Mono, this is how good the stuff stretches.

I find that Monokote varies by color. Some are easier to work with than others.

You just have to practice with either one to get a feel for it, then you can do a lot with either one.

Ultracote for me.. I have not had any of the issues described above. Mono is probably stronger though I cannot tell a difference b/c it's so thicker, heavier which I beleive causes the shrinkage issues and hence harder to apply on compound curves and in general. I gladly pay the extra two bucks at the LHS for ultracote.

I like Ultra the best. It seems that Mono changed from what it used to be in my opinion. It doesn't like to shrink as well.

Solartex is my favorite for scale model covering if I don't plan on using cloth and dope. It's a bit pricey, but nice to work with.
