Not when you insert the ball bearing as recommended:

fly mine as a glider and ma surprised it worked well, bungy launch was a blast! Tail was a bit wigglish but it thermals good so it's not bad for a flying mustache looking thing.

Pressing the bearing into the plastic is definitly a very tight fit. I used a bearing press to do it as I could not get it into the plastic far enough or square enough with my fingers.

Burke: there should have been a gliding canopy in the normal kit ?

Got mine last Friday. Tuning kit included Was delivered with the hollow steel shaft, so no problem there
Maiden was quite easy. More than enough power and a very nice sound.
Launching without motor is easy (just to save fingers). I find it not very fast (like a Funjet) but it has lots of acceleration!
This one will definitely stay in my collection!!

Well I've now got about 10 flights on my Xeno and I'm starting to see what the others were talking about regarding the wing wobble. I don't know why but some days its worse than others and as far as I can see the conditions and airspeed seems to be about the same. I may have to increase the winglet size to see if that will help.

Out in the desert I have to launch with power on and up to this point I haven't had any problems with fingers. I left Arizona this weekend and the Xeno stayed behind as I don't have enough sky up here in Washington to fly it safely. So it gives me one more reason to get back down there as soon as possible. All its done here since I arrived back is rain, rain and more rain

Did you turn the power on low when you launch it?

Hi.
I am thinking of mounting a 10Ah battery on the plane so i need to ask if anyone else has flown this airplane with an AUW of more than 1.5kg or close to this
I already have many flights with it and it looks like it's efficiency and low drag
could make it a nice small UAV for simple video onboard recording (no rf video link)
Anyway i will give it a try and let you all know of the outcome.

Flying wings have rather low max. lift coefficients (due to the reflex wing section); i.e. higher wing loadings will have a severe impact on flight performance.

I agree but i will try to fly one with AUW of 1.5 kgm.
Btw the motor will be located at the nose and not at the back.
I need the back section free as i am trying a parachute recovery system.

Its about at 1/3 to 1/2 power when I launch. Once it clears my hand I throttle it up and away she goes!

I launch my Zagi XL (the large wing in my avatar) the same way, but I had to build a hand hold on the bottom of that one to have something to hold on to.

So far I've got all my fingers.

It looks to me that it does not matter if the throttle is at 1/2 or full as the blades are fully extended in either case.
The danger is high in either case also.
Anyway i have many flights with my Xeno and although every time i launch it, always at full throttle, it gives me the creeps with it's huge 10x7 propeller.
Somehow my hand is still one piece.
So far no one has volunteered launching it for me, in fact everyone i asked his help with launching it for me has refused to, that;s how scared they are when they see the huge propeller at full speed.

I totally agree with you, low throttle or full open you could get your "pinkies" hit, but with partial throttle at least in my experience (maybe its the sound?) doesn't seem as intimidating as a full power screaming launch

Step 1 of the conversion

Here is my new motor mount.
I recognize that this experiment may fail but i will give it a shot.
The battery pack will be mounted on the bottom in line with the plywood in a pod.

In this case, I would have skipped all the heavy plastic parts of the fuselage and added two carbon tube spars.

You are quite right but i had already built this one.
In case it flies well that is the way it will be built in the future.
For this experiment the heavier the better so i can have some error margin in case it succeeds.
Btw estimated AUW will be 1300g, i think it will fly....
I will use a 10x7 or a 11x8 propeller in order to maximize efficiency.
The Robbe airbull i had would fly like a dream with 1500g and it is about the same wingspan
but it was a little slow. It is a shame that they stopped producing it (i may be wrong)
The airfoil was different also but i still hope.
