New Xplorer2 F5J ALES

Hi
I am Ken Bates LSF 604 Level V and a past NATS champ in LMR and ALES. Ihave been Soaring since around 1974. I fly a Xplorer2 in TD, and have after a year of learning, got it set up where it realy performs for me (Radio change helped a lot). For this year I realy wanted a Xplorer2 F5j but the budget and a late decision to sell some other airplanes left me flying my "stormy" .Its a good machine but a bit heavy and fast for light air.
So now I am excited to build and fly this new machine, Talking to Alex at SUSA I found that the explorer f5j had some updates and has been "Polished".Yesterday Fedex del
ivered that big box..... !!
Since I don't often get new sailplanes I am going to savor the build, not rush!
Ken

Xplorer F5J

Ken,

With the new tail/fuse config, shoot for a CG around 130 for starters!
I think you will find that you have "the king" of F5J model offerings>>>>

Best,
Bob

That new tail is pain to put together and take apart but it flies ah so nice....

Stab weight is not anymore an issue since this Xplorer version likes to fly with rearward CG. 130mm sounds radical but it is not.

There is no tray, I would prefer to make my own as final ballance is developed
The tray design should add some "shear" stifness to the nose. (gotta love those crabbed landings)

@ Ken
Thanks for the information about the weight. Sounds like in comparison to the glas version they managed to save some weight again (1165 empty)

Very interesting information followed about cg further back due to the new layout of the tail ......130 instead of 118 .....

Isn't the tray made from ST supplied. I never used it because of poor fit and made a simple one with elevator servo flat in servo-rahmen. Receiver under the servo to create room for easy acces to ballast. Not necessary now because you can use a smaller servo.

Last night as I was test fitting the motor, an issue appeared . The P29 gearbox bolts
will overlap the outer "lip" of the fuselage. I could cut out sections of the flange
or....

After two tries today the photo caption refuse to apear, so
These are views of the fuselage carbon ring reenforcing the nose and the lip.
the modified motor mount with a layer added that is the thickness of the fuselage lip, the fit and clearances of mount and spinner, and finaly the firewal test fit with gluing clam in place.

I went with the Powerline 1025. Not a single issue. Gets to 200m in 20 sec! I love this plane for light air. Just amazing. I'm all up just around 60 oz., but I tend to build heavy anyway. You ABSOLUTELY cannot dork this plane. Trust me on that. I have no idea where my cg is at the moment but I love the way it flies and that's good enough for me. Not sure what the "changes" are in the newer models of this plane.

Now that is different.

Not much today, Grand kids soccer, sailing (weather is about to turn in michigan)
and chores.
Epoxied in the motor mount, and verified the wiring in my TD Xplorer2
I want to be able to bolt on that wing.
I see the descriptions are not apearing even though they are saved.
The first is the Fuselage solvent cleand and masked and the clamp is ready
Second, Epoxied and clamped (Gflex)
The third, verifying the wiring on the TD wing.
