Received my Smooth-E today, WOW!!!! that was fast. Thanks Doug & Matthew.

Before I start,

I have some e-kote will that be ok for the plane or will it be to heavy???

To join the wing parts, Elmer's Probond or epoxy???

18g sub micro or 9g micro for servo's???

Brian,

Probond is great stuff. If you have it, use it. e-kote will work.

Either servo. Saving weight is good. Just choose a servo that is reliable.

I just taped my wing last night, and I think it went OK. There are some wrinkles, but nothing too awful and you only notice them up close anyway.

The trickiest part was taping around the rounded part between leading edge and the wing tip. Last night I was pretty pleased with the job I did, but this morning the tape had popped up.

What are other people doing in this area? Using a little tape strip to hold wayward corners down? CAing them down? Maybe there's some other tape trick I'm not aware of...

You must've had some of the pre-acetone-based 3M77.....

I didn't round the wingtips, which made it easier. Also, you CAN shrink the tape with a covering iron - in fact it will shrink surprisingly well if you're patient. BUT - the difference in temperature between "tape shrinks well" and "wing core MELTS" is not great. You can guess how I know .

Not sure, but it worked. It was in a black can, had it for about 3.5 years. Worked perfectly.

look a couple pages back -- I used colored electrical tape along the edges -- it holds a bit better.

Does anyone have a suggestion on how to better seat the aileron servo? It is just a bit wiggly.

I must have taken too much foam during surgery!

Thanks, Dr. Killd-aire

wobbly servo...


I used a few drops of "foam-safe" CA but any silicone adhesive would also work to secure the servo. If you wanted it to NEVER move, you could always shoot a little Pro-Bond along the side...

I used some 3M 77 adhesive as well, and NEW stuff at that. After researching the topic here on EZone, some people say you can use the new stuff if you're careful, spray from a distance (2-3 feet), and LIGHTLY mist. They say this helps the Acetone evaporate before it eats any foam.

I don't know about that, but I did my own tests on a foam cooler. Light misting didn't seem to eat any foam, and made things pretty sticky. A heavy spray did eat some foam, but not a lot. It seemed to take a puddle of 3M77 before noticeable damage occurred. But your mileage may vary, and anybody who doesn't test first is asking for trouble.

Anyway, the tape stuck well to foam with the 3M 77. However, I was having a problem with tape sticking to overlapped tape. Especially where I had to gather the "slack" in the tape to fit the contours of the wing, but the slack got in the way of the tape adhesive.

Maybe I'll try the electrical tape...

I lightly misted it. Didn't notice, or even knew that could happen. Just followed the directions in the instructions. Luckily for me nothing happened.

Something to consider, it's good to wash you hands before you begin taping. And know that your surfaces are clean, don't ask me why I know this. Heat, within moderation can be your friend. I say that cause if you melt a wing, you might pay us to buy another! Just kidding.

OK,

I just finished sanding all my skin of my smooth-e and now I'm picking the CA glue of my fingers.

Question:

When installing the servos the servo wire is in the way when putting the servo in the cut out. What is everyone else doing for this??????

You should be able to drop the wire in first then rotate the servo into place. You may need to open the hole just a touch.

If needed, you can use the two ply parts to support the servos once the hole is opened.
