About one month ago, I purchased two new rolls (14 feet) of white Monokote from the LHS. They were the "seven for six" rolls. I've been using the heck out of that stuff for 24 years. The new white Monokote reacted to heat very much like Ultracote, only worse. I couldn't burn a hole in it. When I beared down on in with a TopFlite heat gun, it just sagged away from the gun. I couldn't melt a hole in it with my Coverite iron, even if I left it on high and sat the iron on it for 10 seconds. Folks, something is definitely different. If one doesn't tighten the stuff up real well before trying to shrink it over an open bay (like a wing rib bay) you aren't going to get it tight. Both rolls had the same characteristics. Monokote was always the covering we could depend on. I can't imagine what the manufacturer was thinking when they changed it. I wrestled with trying to get the covering on the wing tight. It still has something to be desired and it's not as tight as I would like it.

I emailed Topflight / Great Planes / Hobbico customer service with a very polite question about it and was completely ignored. Have any of you all experienced the difference in Monokote? If all colors are going to react this way, I'll stay a mile away from it and find an alternative product.

Thanks for any information you might have,
