Hi,My name is Russ and I am just getting back into robotics and automation after a 20 year hiatus. Between the interest in robotics and being an airplane nut, I naturally ended up here. Anyway to my problem:I just maidened my easystar, got one 2 min flight and landing in and then on the second flight as I throttled up the prop left the aircraft never to be seen again....thanks to my natural catlike reflexes (tongue firmly in cheek) I managed a smooth deadstick landing.... anywho is there any better way to keep the prop on the plane? I used 5min epoxy cured for 24 hours.ThanksRuss

Ok so I bought a real prop adapter and have been experimenting with new props. Have put in 20 flights in a row without major crashes so I am now comfortable trying to manual fly with cameras....then on to ardupilot etc...
Roughen up the motor shaft with some sand paper before using the adhesive, this will greatly help it's ability to hold the motor shaft. Most shafts are polished.
sorry, but I don't quite understand what you really mean by "throttled up", I thought one would throttle down and to go faster one can "accellerate" or such terms? Nevertheless it puzzles me for another reason: the EZ has a pusher propeller and uses a prop adaptor to fit it to the motor shaft --or not?? A pusher prop usually would be pushed on the shaft and does not come off when you start the motor, unless the motor runs the wrong way 'round or the prop has the wrong direction of pitch?
It is not clear to me whether you used the 5min epoxy for fiting the prop directly on the shaft or to secure the nut which tightens the prop on the adaptor? There are litteraly hundreds of EZs flying around and I have never had a problem myself or heard of one with the prop adapter.
Perhaps you can be more precise?
JB Weld worked perfectly for me on the old stock inrunner engine. I assume you are running that one, right ? If so JB Weld, put it on, let it cure 24 hrs and if it comes off then, well I will be shocked :)
Ummm,... I don't personally fly foamies, but out of curiosity is your prop glued to the aircraft or the motor !? (I'm joking!!) I've actually never heard of anyone using glue to secure their prop, so this is quite amusing.
I suggest you go down to your hobby shop and get a prop shaft adapter to suit your motor.

On the whole I agree with Ios.
