After CA'ing the coupler to the rod, slide a small section of heat shrink tubing over the coupler and overlapping the rod. Drip some CA inside the heat shrink tubing. Use your torch to shrink the tubing. Some Ca will push out of both ends. The coupler will never come off.

I managed a 35 minute flight with the Xplorer yesterday....
I did experience one small problem though:

I got a sore neck, and started to get a bit bored, so had to land, and intentionally came down, in one piece.

Nice flight wingman!

Yeah, that was fun. We'll have to do that again sometime.

Two thumbs up! Beautiful planes aren't they.

Folks, could you please help me out and comment on the flying chracteristics of the NAN-F3J airfoil of this model? I'm not experienced in airfoils and want to know the difference between this airfoil and AVA/Topaz kind of airfoils. I know some airfoils are rendered as 'fast', others as 'slippery'. What is the kind of the 'NAN-F3J' one and what does it add to the flying performance of the Explorer? Thank you!

Nice, very nice!

Does mean an all new build thread (I hope, I hope)?

More 3800 info

I have only just removed the plane from the wrappings, so I do not have any build info nor finished weights. My standard outfit will be used, with 3421 in for the flaps, and everything else gets 368's. Power will be a 2S Li-Ion Relion with a Castle Creations BEC, all JR euipment and guided by a JR X9303 2.4 system.

The specs: (I know you wnat that)

Wing center panel: 56-3/16" long, same chord as original @ 10.5"

Outer panel: 47" long @ TE

Fuselage: Same as original

Stab span: 32" @ TE, 5-3/16" chord at root

Will the wing fit an earlier fuselage? Let's see......Indeed, it does! Perfect match on my X's!

I really have to pay attention to my dinner right now, before it burns, but I will keep you updated on how this project goes as we progress. I'm not good at figuring out wing area on an elliptical wing tip shape, but my guesstimate on total wing area is about 1,270 sq inches. If this is true or even fairly close, and we take the average of X plane weights of 76-oz, then we will have a wing loading of 8.6 oz/sq-ft....awesome! And if we come in lighter, that's just icing on the cake!

Man, that is a sweet looking ship. Very 70's retro sloper.

Sorry, but my eyes must be getting worse than I thought, cause I just can not see what you are standing on, my friend.

I don't understand why a plane is designed painstakenly well with certain proportions, then a year later they add a foot to the span without changing the fuselage. I mean if they started with the new 150" wing first and then designed the fuselage, wouldn't the fuselage be longer than the one used on the 136 inch plane? Seems there should be a tradeoff somewhere?

Mike, not trying to rain on your parade, just wondering ?

Hi Clay,

You're not raining on my parade. But I do whish for you to consider this;

The Xplorer followed on the heels of the successful Shadow design, which was 144" wingspan and it had a very long fuselage for the design. Xplorer then comes out and it has an even longer fuselage but shorter span than Shadow. So, having the longer wing probably won't have much adverse effect on the handling other than a bit quirky yaw moment in comparison to the very smooth movement on the original X. I am only thinking this MIGHT happen, so please wait to see what happens in real life before we make any judgement calls. I'm only a beginner at aircraft design and don't hold a candle to the guys who do this for a living. I understand about an inch of how things work in the aerodynamics world, where guys like JW might know miles worth. And then you have Dr. Drela! So, again, let's see what happens when this plane gets into the air.

Thanks!
Mike

I agree.

Having flown Aspire from the beginning I also know that building a large ship with optimal weight/strength relationship is not easy. Somewhere here is a post by Lubos about these difficulties... First Aspires were little (not badly) heavy. It took some time from Lubos to finalize the structure.

Large ships are kind of fun to fly, but I believe in a more incremental approach to plane development. Having a large plane with inadqualte structure is not the right approach for competitions...

Anyway, all the best to NAN :-)
