Nose dive? I launch my Xeno with the motor off and it goes up - not down.

Have you programmed down elevator with power on? That would explain such behaviour, as the servos would move quicker than the model would need to accelerate.

Today I flew my Xeno.

This time, I attempted to fly her as a motor assisted sailplane: power-on climbing, power-off gliding and thermal hunting.

The L/D of Xeno is not so bad and total flying time came 12 to 15 minutes in almost no lift conditions. I limited the total power-on time under 4 minutes.

BTW, Akihiro, my club fellow, took a short vid.
Sorry for not so good launching

Well, I've owned quite a few Mulitiplex planes...

Space Scooter (x3)
EasyStar
TwinJet (x3)
Gemini (x2)
FunJet
Blizzard (building now)
Merlin (on it's way)

I was interested in the Xeno, mainly because of it's "fold in half portability".
But after reading this thread, I have to say that I will be passing on this one.

The main reason is...
After seeing a picture of the Xeno sitting next to a FunJet, it is clear that a FunJet made with removeable vertical fins, is just as "portable", and likely more durable, than a Xeno folded in half. Add to that the complexities of the Xeno's drive, and the net cost - It just doesn't add up.

No disrespect to anyone who has one, desinged it, sponsors it, etc.
Just my $0.02.

Hi Cliff,

A folded Xeno will fit in the overhead bin of an aircraft, the FunJet won't.

The Xeno is mostly a glider and a nice slope soarer, the FunJet isn't.

+1 The folded Xeno fits nicely in the trunk of the car. And so does all other equipment like batteries, charger, transmitter etc. The FunJet doesn't fit and must be on top or on the rear seats (okay, it does fit easily in my SUV but doesn't in my wifes car ).

I've had several Easy Stars and still have a MiniMag (with much LED lighting for night flying ), FunJet and Blizzard and I have to say the Xeno is a nice "in between" model. Each model has it's specific characteristics and is fun to do what it's best made for. So does the Xeno.

can't see any relationship either between a Funjet and the Xeno ...... they both have their unique areas of interest ......

ps. although a touch of 'up elevator on a switch' for take off, I would find handy for both models .....

Agree; something about it ain't the same f* ballpark, it ain't the same league, it ain't even the same f* sport like some Yanks would say in a Tarrantino movie...

Nice way to save your fingers

I limited my motor power-on time to 4 minutes too and had flight times
without thermal conditions up to 20 minutes
looking forward to better conditions

greetings from Austria

Due to the low speed the first meters are near stall speed in low wind conditions. Look at every video when launching the Xeno. 2 meters straight forward, then starts to dive about one meter down picking up more speed and the flies away.

Well, I can hand launch my Xeno and fly a 360° circle without turning the motor on. I can also launch slightly upwards and gain extra height before turning the motor on. Probably have to get Jim to do some videos.

Once upon a time if there was anyone who would post a Video about any model it was Jurgen ......

I can't rememeber any videos of you and your Xeno .......

Please Jurgen ..... don't be shy .....

ps. my Xeno looses height on launch untill I power up ..... one exception .... if I launch into a good headwind then up she goes ..... no problem ....

Can't fly and record at the same time.

If you launch fast enough, you can climb a few meters before you start the glide.

Too lazy to do a good throw. Best way is to give it full throttle and let go.

This has nothing to do with lazyness, but about guys who are worried getting their hand caught by the prop.
