LX models already makes the SU47. Granted it isn't the same Elapor but it's a very nice airframe and it's HUGE. Where is VRFlyer so he can put an FPV cockpit in this thing.

If I ever solve my horrible servo glitch problem on my Funjet, I'll think about getting this new one.

That SU47 looks nice, but that plastic landing gear just looks like it'll snap off at first landing ...

Cheers,

Sander.

I was aware, however id much rather have it in the form of an elapor bash plane.
One you dont need a tarmac landing strip for.

Hmm, i must admit, retractable landing gear is a constant headache... When i was living in Thailand, i used to fly at PST Jets private test runway which was a perfect bit of tarmac in the middle of a Rice Paddy (PST make model gas turbines and used to do all my CNC work).. Literally EVERY problem / crash / damage was due to landing gear problems.. The main guy at PST Jets (the CEO) is actually a 747 Pilot in real life, and i never forget the touch & go he had to do with a prototype jet which had one of the landing gear struts stuck up in the fuzz, there was around 30 of us there and the guy who was flying past the controls onto the CEO airline pilot guy (i forget his name) and you've never seen the skill this guy showed to land the jet & get the gear down.. he got a standing ovation from us all in the pits!

So from my experience of watching literally tens of Jets be seriously damaged from landing gear issues would make me really nervous... So valid point Sander, i think that's put me off too..

Cheers

Andy

Turbine jets are several times heavier then those foamies though.
Not to mention those jets often use pneumatic gear right?

Yeah pretty much... But the other thing is where i fly, i've not even got the luxury of a perfect strip of tarmac in the middle of a Rice Paddy... just a lumpy bumpy grass feild, which would rip any gear off, even if it was Titanium, let alone plastic

The FJ Ultra reminds me of the C/F mod funjet. Clean the wingtips and thinner vertical fins.

They are surprisingly solid, even more than some other manuf. metal ones.

Well, if the plastic doesn't give way the foam will

Silver colored foam might as well be invisible against grey clouds, and it makes a
horrible base for flouro paint (discovered that on my silver winged EZ*)
Regular Funjet is more than quick enough for FPV.

Coincidentally, just 10 minutes ago, the mailman dropped off my new
Skyartec Funjet. They didn't have the RTF version in stock, and I didn't
need their motor and servos anyway, so I simply bought all the individual replacement
parts to make one (fuse/hatch/canopy/wings/fins/motor mount) for considerably less $
and shouldn't take but an hour to build. Foam is more dense than Elapor and
probably more brittle. I hadn't realized from photos I've seen of it, how much
larger than the Multiplex Funjet it is. It appears to have quite a lot more
wing area, and a fat lifting body. A massive amount of room under the canopy
for gear. Not sure how I'll mount my pan servo.

ian, what have you done so far on your skyfun? I am just about to start on the camera mount, and think it should be behind the plastic canopy, but on the canopy foam. I think I'll skip tilt.

I've done nothing at all yet. Some people are inspired to build when the weather
is too crappy to fly. I'm not one of those people. I need to be able to be able to fly
to be inspired to work on new projects, and the weather here has been
really cold and dreary, and snowy, low ceiling etc, so not much is going on.

I won't put the camera that far back. I'll probably glue some foam into the
canopy and mount it to that through an opening in the middle of the canopy.
