This is my preferred method also. Tell me, how did you strap that on. Looking at it, I imagine you laid a strip of material down, with a loop glued in behind this (ie, not going through any foam) - but I may be wrong?

Maiden day for me today all going well

A note for anyone wishing to use the Omega 72g motor. the motor is a short motor, and you will either need washers around the mount screws, or a couple of thin washers on the motor shaft end. I put two washers on before the prop, and clears the foam by a couple of mil.

Oh yes, this is indeed a fab airframe!

I had an absolute ball with it on it's maiden today. A beautiful day, steady breeze, totally deserted feild, and took the Sbach and the Wattaplane Edge 540 48". A great combination to compare things.

Well, to put it in the venacular, this plane 'rocks'!! Seriously, it is just super.

The Omega 72 + 1600 3s on a 11x7 is a super combo. I'm very satisfied, as I know I can up the batteries from my old worn out 1600's to new ones, and up the prop.

I have to say, very, very locked in feel. A very different feel to anything I've flown in that size. Very different to the edge (which I love BTW for high energy moves, esp blenders to spins!!). It inspires confidence immediately, and I was not afraid to rip it up right away. Blow back at full throttle, but to be expected as I understand.

Snaps are just lovely to behold in that wingspan and design. I could go on.,,,, but instead, I'm charging up and off out to fly her.

Video coming. Again, I would say if feels and flys precise, low, slow, fast etc. I prefered slow KE, as full throttle did strain my servos in a aileron roll, but I need to tweak my servo arm hole in two holes to get better 90 degree.

Anyway, although the build took me ages, and took its toll on me (not a criticism of the design, but a reflection of the builder!) it was worth it all today.

PS - lateral balance was not an issue with a 1600 strapped to the underside. I even popped on a 2200, and flew good, but lat balance was off a little in a hover, as I expected. BTW, all 6 or 7 batteries held on with no strapping, just velcro to velcro, and I did hammer it. Anyway, I will strap in future to be sure.

The Velcro strap is not glued in. Just slit the foam enough to slide it thru.
The foam will keep it in there. I just strap it snug. You don't need to pull it hard. The battery won't go any where. These planes don't tumble hard enough to eject the battery with that simple strap.

Your Welcome! It was a lot of fun to do. I am galde\ you are liking it, it has become my go to plane.

You mentioned that you felt no balance issues with your bat Velcored on. I have mine Velcroed/sttrapped on the bottom of the fuse. It feels to me that it may be effecting the balance so yesterday i cut out a slot on top the fuse. It was to windy yesterday to test, maybe today.

That 72 gram Omega should be a very good fit for this plane. The actual wieght is around 95 grams. Great little motor for the price.

I'm surprised there are not major lateral balance issues with the lipo there as well, there certainly were with mine, it has become totally different to fly since I moved it.
I can't remember whether you had any Telink models or not, but I woulkd be interested in your comparison with this if you do.
Pleased the maiden went well

Good thing I picked up two of the 2 paks of welders - as I have 1 1/2 tubes remaining :-)

Wow!! So I cut a hole for my battery in the top of the fuselage to center the balance laterally and it really made a noticeably, positive, difference in the flying characteristics, mainly or mostly in the KE flight or, that is where I can notice it the most after only a few flights with the change. I also moved my CG back a tad.

Now it is not a huge difference but noticeable. I can understand why Mike Smart was having and some may still be having some lateral balance issues. I think I was compensating for the balance being off without even realizing it.

I would recommend to those who are strapping their batteries to the side of the fuse, that you may want to make a cut out and install centered in the fuselage. I used a Velcro strap to hold it in and so far it works well.

I posted a couple of pics of how I did mine. If anyone has a better method, please include them in a post. Always looking for a better way.

Thanks for the advice. I certainly will be exploring that option. It alwasy takes a while to get a feel for the plane and I'm bound to find out more over the coming few flights. I do have a technical question I'd like some advice with, but I need to get some photos first. I'll post shortly.

OK - here's my question: to those who have built this model, how did you align the rear wing root? I aligned the front perfectly to the siffening carbon spar. I then aligned the rear to the spar, but as I examine it closely, the centre of the rear wing root is probably 1 or 2mm higher than the spar.

The reason I bring this up, is that on my maiden, I did find (although only briefly tested) that even by moving the battery, I could not achieve hands off inverted (after keeping elevator neutral). I got to thinking that, perhaps, if the rear of the wing is slightly higher, it may act as an elevator, thus giving rise to decent in inverted? However, this amount seems so insignificant.

Does your rear wing alignment look similar to mine ontop and underneath as my photos show? Any comments appreciated. Being all EPP, it would not be a great deal to slice an inch or so into each wing and correct this, but I will refly first.
