I think the laminate is just plain tougher. Monkote will tear once the surface is breached, kind of like plain packing tape does. Apply the two layer and go with it, Lee knows what works If you tape it or go nuts making it any other way you may add too much tail weight and will be forced to add nose weight even with a large battery. It needs to be strong but it also needs to be light. That is also why you slice the hinge tape and some of the other tape strips in half, save weight were is can be saved.

well I am building exactly per the instructions. Just started thinking about the coloring issues which got me thinking about the other products out there and how they compare.

There is nothing wrong with using other iron on colored laminates. Ultracoat is the strongest. Realize that you will have to spray the foam core with 3M77 or 3M90 to get the other laminates to stick which adds building time and weight.

I use them my self at times. I found them to be more expensive and weaker than our laminate. I have used many different iron on coverings. The clear laminate we include in the kit is stronger than any of them for its weight plus it is included in the kit. Many of the different colored laminates will split when the plane takes an impact more than the laminate we sell so I don't recommend them in combat but it is all a personal choice.

I made a 3 hour drive to a meet with a few planes and a tricopter behind the seat of my truck. I didn't realize until I got there that the tail servo push rod's cut off end was pressing against the laminate on my Assassin the whole way. But it did not puncture. Instead, it bent the Z end further.

Try that with 'kote.

I suspect you are over thinking the build if you are taking the time to measure the laminate versus Monokote. You must have access to some pretty specialized tools to make measurements like that, I wouldn't have a clue on one might find those numbers? And as all teachers say there are no dumb questions, so good for you for enlightening everyone on the subtle differences between the 2 materials.

I used colored Trimkote from Tower Hobby. I did the build up to the taping. Then applied the adhesive trim over the tape and foam for my design. I then ironed the trim as well. Then laminated as per the instructions. It's worked very well. The guys call my Assassin "Spot" because of the big dots on the under side.

I built mine per the instructions and then used blue painter's tape to distinguish top from bottom. I've crashed it many times and it hasn't pulled up yet. But I did order some bright colored packing tape ("wing tape") from HK to make it stand out a little more. I assume it'll stick to the lam at least as well as painter's tape. And when/if it comes up I'll use that as an excuse to make a new design.

I probably overthink everything. The measurment was not that hard. I have a $12 digital caliper off Amazon which is very useful in this hobby, especially with measuring the small crews used in helicopters. I am an engineer and I like to understand different materials and properties and I like to know why one material is used over another. Not saying there are not good reasons but lots of times people do something just because everyone else does.

Lee: Thanks for the input. Adhesion to the foam is important. I had not thought about that.

There are a lot of differences between the laminates.

Our laminate doesn't shrink as much and I think that is why it doesn't get so brittle. It is easier to apply because you don't get so many wrinkles. I'm sure the spray on adhesive also plays a roll.

If you look at my planes that have an Ultracoat covering after 2 years, more of them have loose laminate than we see on the clear laminate we include in the kit. the laminate adhesive is better than the 3m77 spray adhesive.

The clear laminate doesn't show wrinkles as much but you need to add color to stay oriented to the plane and see the plane against the clouds.

My son Mike paints his planes and the clear laminate sticks to the paint .

I'm building mine per instructions and ordered a couple of rolls of holigraphic hola hoop tape from paperstreetplastics on ebay to doozy it up a little, a couple a black stripes across the bottom. and a friend made me a small vinyl Assassin graphic and thats gonna be it! keeping it simple for the first one...going for the widowmaker next! might play a bit more dress up on it? I got this feeling these wings are going to be addictive! a dozen planes & couple of Heli's and now the wing! My wife is me! but I told her, hey, at least it's not drug's & alcohol and chasing other women! that always works! you buy shoe's, I buy plane's.....

Started my Assassin build this morn and it's going smooth but I got to the elevon's and I noticed in most pic's that the outer trailing edge of elevon's the corner is cut off? but I don't see it or a measurment in instructions? is this a critical measurment? or for looks? it seems to be about an inch and a half to me? Ok disregard that Question, the more pic's I look at I see that it's a little different on every one. I'm guessing getting both the same is most important. going back to work!

Spray foam then laminate IMHO

This is what paint over lam can look like after a few weeks rough and tumble!
( Rust Oleum flourescent, looks OK on foam)~~~~~~~~~~~~H

The measurement was in my version of the instructions - it's only done when not using winglets I believe, so I didn't do it.

No, the measurement your talking about is on the wing itself, It's 2" from leading edge tip towards nose & 2" towards tip of trailing edge. I cut that off, I'm talking about the elevon tip.

Some of us trim the ailerons a little to save them in case of a cartwheel and not much is needed. Mine are trimmed, my friends are not. My Assassin #2 will not have them trimmed. My friends seems more stable in slow turns then mine.
