Well, I've flown this plane several times now. Here are my thoughts...

First off, I must say that it is a strong plane. A mishap of sorts has proven that out.

The plane balanced perfectly on the spar with no mods done to alter CG. The 3S1P Thunder Power 2100mAh pack is attached to the floor of the fuse using velcro. The rx is on the bottom of the wing...again, with velcro. This allows the batteries to be changed without disconnecting any servo wires.

OK...flying. If you can't make this plane harrier, it's because you forgot to take off. In fact, with the CG on the spar, harrier flight is about all I could get! So I moved my battery pack forward 1/2 inch and found a sweet spot - where the plane will fly on the wing nicely, yet still harrier easily.

I used some motor down thrust after the first few flights. Made all the difference in the world! This, combined with moving the CG forward a smidge, really makes the plane shine for me.

This plane is about as easy a plane to hover as any I've ever flown. I could take off, and just hover a pack away if I set my mind to it.

It has some severe coupling issues in KE flight. This is not a surprise, since there is so much weight in the bottom of the plane - way below the roll axis. This makes the plane easy to harrier, but brings on other issues like severe roll coupling. I'm considering building a battery tray just under the wing to see how that affects rudder coupling and the non-axial roll tendency. I could try aileron differential for the axial roll issue, however with the batts so low in the fuse, this will likely be an inherent trait of the plane. Again, I will likely move the battery upward just to see how the plane reacts.

TOs and landings are very easy. You don't need much power to get this thing to leave the ground. The LG seems quite strong, though I haven't really tested that (since it is so easy to land.)

Since there are so few kits for this power package, I would likely build another Vertigo 125 if this one was destroyed somehow.

Overall, I like the plane and would recommend it to someone looking for a kit (not an ARF) in this size range.
