Seriously considering one of these!

Gonna go back through the thread.

Anyone want to offer their approval/disapproval? strengths/weaknesses etc.?

Great when you don't want to break your 3mm depron indoor plane. Definitely not as precise or floaty as 3mm depron indoor. But, does everything reasonably well. Doubt you'd find an indoor EPP that flew 3D much better. Knife edge is particularly good.

I was flying mine last night (indoors), along with a new ultra micro 4Site. I think the Piaget looped tighter, and needed less space!

I take mine with me wherever I go. I mainly fly outdoors with it. It's fun, easy, and doesn't break. I mainly use it for 3D flying.

I have now flown the Piaget a couple of times indoors.
When I turn around using the rudder it drops quite much in altitude and I have to use quite a lot of opposite aileron. Is this common for you guys to? Anything I can do to make it better?

My setup

Donuts E-power 2203 1700kv
Turnigy 10A esc
Graupner 8x3
Dymond D47 servo
2S 360mah & 600mah

Weight: under 200g AUW, dont have exact weight right now.

Other people have reported this, but mine seems OK. It did flat turns a little nicer without the side-force generators on the wings, but there wasn't much in it.

Where is your CG? Mine is a long way behind the specified range, but the plane is still perfectly controllable. Maybe having an aft CG helps with rudder turns.

I think that is just what it is going to do, since it is a lot heavier than a 3mm depron foamie, and so with a tight turn, it is going to drop the inside wing a lot more due to the reduced lift. You will find after a few more flights that you compensate for it without thinking.

CG w/ 2S360 about 100mm from where wing meets fuse
CG w/ 2S600 about 85mm from where wing meets fuse

AUW with 2S360 173g and with 2S600 192g.

I was thinking about putting sideforce generators under the wing aswell, maybe that helps out.

How on earth did you achieve that (left bits off?)?

With 2S 360 mine is 197 grams. So my CG must be further aft, I would try that first.

Thats exactly what mine did. You can try moving the battery back further and maybe removing the single strake on top of the wing. My suggestion is sell it and buy a Clik 2.

I have an Ikarus Yak that has a little more wing area than the Piaget and is 159 g AUW. I prefer the slow speed handling of the Piaget!

Well, first oof all I don't know if my scale is correct.

But I have used lightweight parts. Motor is only 18g, servos 4,7g. I switched the flat carbon to 0,6mm and used as little glue I could.
The RX is a Spektrum AR6110.

I dont like to have the CG to far aft because then I find it hard to fly knifeedge.

Mine knife-edges very nicely, the biggest issue is that only a touch of rudder is needed so even with lots of expo it is easy to over-control.

Yep, exactly what happens to me.

Yesterday I did som inverted flying, and I noticed that when I turn while inverted it does not have the tendency to loose altitude or fall in.

Guess I have to fly inverted from now on

Well I have another Piaget "handy hint"

The motor bulkhead is just a ring of ply. If your motor has a lightweight X shaped rear mount (like my Hacker) and you hit something, the motor can move back ... bending the mount.

This happened to me yesterday after a mid-air. The plane was unmarked, but I noticed it now had a load of left sidethrust

So fill in the centre of the bulkhead with balsa, so the motor mount cannot be bent backwards.
