F3J in Rockies

Howdy,

A big congrats to Blayne for his win at the F3J in the Rockies! Consistent flying, and lots of 100 landings made the X 4000 look great!

AND Rich B. and Tom K were 3rd, and 4th.... good work guys!

And who is this Dillion kid?? Looks like he would have been 5th instead of his 7th position finish had he not landed out in the late afternoon brutal conditions.
Looks like this junior can hang with the "Big Dogs" ...

3 out of top 4 pilots flew Xplorers.... 5 out of top 10 flew Xplorers...
Some great pilot skills with the right "Tool for the job"...

Best,
Bob

X2 Update

Hi All,
I've now had the chance to get some stick time on the X2, Im flying the 3.8 standard lay-up.

All up weight done - 1800g, great result! I didnt build light, I built for our aussie conditions which calls for durability. Having said that @ 1800g the model has handled its test conditions really well. 1st day out was blowing 10 knots+, thermic conditions with stronger gusts. Straight off I was really impressed with how easily the model covered sky, yet add camber to the party and she can hang. Its a big hand chucky!

Im really impressed with its broad envelope too. Its got legs, can hang and crawl when needed, and I finally got it dialled in today where I can spin it round on its tip when required in tight cores. In fact this has probably been my only challenge when getting the setup I like. Lots of tinkering with differential and rudder mix to find the right combination. Landing is super easy too, yank on the stick and those big flaps bring it to a stop. Put the flaps away and its as you were, slight drop of the nose and she's back on pace again. Im pulling around 85 degree flap, it works. Plenty of elevator authority too in the landing circle to hit the spot. I am finding the X2 can be unsettled easily by turbulance on approach, I guess its a trade off with the light weight, and the extra diehedral in those big light tips.

Overall I've found the X really easy to setup. In fact I took my current Perfect ET settings for first flights, and tweaked from their. I've been an ET Samba flier for years now, and flown the Aspire in anger/competitions a few times too. Using these as my yard stick I'd say that the X2 offers broader capabilities than the ET. How much more, only small percentages on each of the things you typically measure against (hang ability, LD/legs, ease of landing etc..), but enough to make a difference for me. Has very similar performance levels to the Aspire, but has the weight advantage for light air.

I've settled on a CG of 131mm from the leading edge.

Its a keeper for me, Im really comfortable on it after only a few days out.
The only challenge now is getting enough ballast in its belly for all conditions.

Thanks team SUSA!

I totally agree with the broad envelope. It has a much larger usable flight speed range than the first version.

131mm !! I really thought I was close to a rearward CG at 121 lol - I would have to switch battery setups and go with a smaller battery or put lead on the tail to get 131.

When the SL ships come here ill have to put the battery in the tail to get that CG!

Every, time I fly the plane I see major differences. It's a total step forward. Now if somebody could do something about the rain in BC...

Does anyone know where I can get a 3 sided view planform of the the X2?
Anyone want to take physical dimensions and draw one if there isn't an offical planform 3s view?

Is it? I've not looked at one closely enough to know. Can someone with both versions confirm? Thanks.

I dont see any difference in planform. But my TLAR is a little scuffed up - you should come to BC and compare for yourself!

As far as I can tell, the dimensions are the same on the 3.8 X2 vs 3.8 standard.

Tuomo, I have plugged new tips on old CPs and old tips on new CPs and they all fit perfect...
Except for the airfoil!

Yes I know. That way you can make 4 meter Xplorer1.5

I'm going to be making a few carbon adaptor plates for MPX plugs. These will drop right into any Xplorer. Would anyone be interested??

Machined \ lazer cut ? ? yup id be interested...ideally though a non conductive material would be better...like some reasonably strong plastic.

Machined carbon, the whole fuse is carbon, and we bolt DB9's to it, so I'm not really to worried about that. Only the plastic MPX connector with be touching the carbon.
