Sound about right?

Just holding it and exercising the control surfaces, seems to be pretty nimble. with all the air being blown.
Tommy,

It all sounds good! You can reduce weight a bit by dropping back to 11x5.5 prop. The weight of the prop is something we often forget to examine. Prop weight goes up almost as the cube of the prop length. I'll have to weigh them when I get home to get the exact difference. The 11x5.5 will also give you a bit more endurance (at least for flying).

Looking forward to the report on the maiden flight. You will find that the AM is more than pretty nimble.

Thanks Ben and Randy,

Interesting not about prop selection Randy, I'll keep that in mind. At this point I am probably wanting longer flights anyhow. I was taking some weights along the way and estimated my weight would be 32 oz., but I didn't way the prop, prop adapter, they y adapter and velcro. I could probably lose most of that 2 oz. if I wanted too.

Thanks again.

Tom

Hi guys,

Forgive my ignorance, but I'm just putting my first AcroMaster together. The instructions give no mention about how you actually join the wings. Are the dovetails meant to push together and snap in place? Mine seem way too tight to actually do that.

I inserted the unglued spars into (1) completed wing (side), and installed it into the fuse. Then I guided the 2nd wing onto the spars and pushed both together until seated. They are a bit tight, and you want this.

Thanks Mike,

But can you get them apart again? I have a small car (BMW Z4) and need to disassemble to get the model in.

Yes. They do pull apart in case of a mishap as well.
I only wonder if this will degrade the holding power over time....

Thanks for asking the question about wing joining. I was wondering that one myself.

Not sure about the over time issue on this plane but the wings on the Easy Glider join the same way.

My Mega powered Easy star employs the same. Everyone seems to watch in amazement when IT doesn't taco.... My AM is way overpowered as well, with no signs of hurting it's stout structure. I fire anuerysms and wicked snaps at it alot. I do leave the wings in at all times, as a crew cab can carry SOME foam.

Mike,

I trimmed off the dovetail and just press them into the fuse. Occassionally after several snaps or other high stress maneuvers, one wing is a bit loose. But it is easy to assemble and disassemble. If they begin to get too loose, I'll just drill a hole through the turtle deck and wing and use a CF stick to hold them in place.

If you don't trim it, you can press them together and apart several times outside the fuse to ease the fit.

Could those of you who have built the AcroMaster tell me the best glue to use? CA like the manual says, or polyurethane glue like Gorilla or Sumo brands? Also, I was going to epoxy the motor mount in, but have heard epoxy won't bond well to Elapor. What do you guys reccomend?

That probably cut a bit of weight off as well. The wings really stay in???

Mike,

At first, I had difficulty getting them together until I discovered the right technique. Once you have the wings mostly in but need to get the dove-tail to fit into place, I grab the wing tips with each hand and pull them together, towards the fuse. It works really well for me.

Getting them off easily... well, I haven't figured out that technique other than to pull the leading edge of the wing, then the lagging, then leading - basically rocking it out slowly.

I like the snug fit - it really stays in place nicely.

It is the same system as used on the EasyStar and the EasyGlider - and it works very well. You may want to put the wings together and take them apart a couple of times to loosen the lock function a bit.
