Hi Tuan,

I have to say, the increase in rudder movement is very apparent on my X2 compared to the originals and carbon lites I have. My normal original runs with 45% mix to the ailerons and the X2 is closer to 60%.

Thanks Mike! This will help me get the plane dialed in faster. I'm going to be in a mad rush now to get the plane done before F3J in the desert. Just can't seem to get more than 1 uninterupted hour in the garage until kids start tugging at my shirt.

I'm super happy with my 3.5X2 and X2 E. I shifted the CG's back to 123 to match my 3.8 and changed the throws to match the 3.8, slightly less diff, slightly less rudder mix, although it's still a lot. Now I have 3 X2 variants that fly amazing.

I like these models more and more each time I fly them.

Hey, I am sorry to post here, but need to ask a favor. Would Xplorer fellas go here and test out my video feed to give me some feedback?
I am using a camcorder to capture a video I made ( since its the only non copyright video I have in HD) a few days ago to test my live feed for the F3J in the Desert.

Can you try using the chat feature too?
Thanks for any feedback.

Can anyone go in and test and let me know how it looks and sound?

I'm uploading at a very slow 1mbps and on Jim's network should be able to do it at least 5x faster.
However using my camcorder with firewire out, I need to use an older laptop as none my my current ones have firewire in and the old one can not convert the video fast enough... too much cpu usage so this is not HD quality.

I'll go see if any of the current usb cameras have good enough HD video.

I rigged up a moving object to see if it causes any ghosting.
You will need to register for a livestream account and search for f3j.

Once the video feeds, there is 3 small boxes at the bottom right corner.
Chat view, expanded view and popout view. Play with it and you'll see what it does.

Feedback will be appreciated. Thanks!

Hi Tuan,
I logged -in using Facebook and this is what I see @ 12noon est

Hope this works out as I'm interested in doing something similar down-under.

Hi there,

can anybody tell me what is the typical weight of a RTF 3.8 II, ST unpainted?

Can you also share your thoughts about the unpainted carbon skin?
I have the fortune to fly in New Mexico, a paradise for soaring, but also very sunny and quite hot during the summers and I am worried about possible over-heating of the unpainted black air-frame.

What do you think?

The temperature shouldn't be a problem. I've flown my unpainted 3.5 X2 in 100+ F sunny weather without an issue. If you are talking about flying in 120 F weather, I can't comment. But I know it is good to a bit over 100 F ambient. Actual wing temperature is much higher. I never measured it but I would guess it is around 140 to 150 F. So, the glass transition temperature for the epoxy they use is pretty high.

The issue that I have with the all black wing is visibility. Essentially you are always flying a silhouette. So sometimes orientation can be a problem. Not a good thing when flying at large distances. I don't recommend the all black wing for this reason. The weight penalty is very small and really not worth worrying about. NAN is pretty good about not using excessive paint to begin with.

Not sure what the weight of the current 3.8 ST are, but I know they are pretty light (mid to upper 60 range?). I'm sure someone will chime in.

I picked up a new 3.8 yesterday, the bottom is natural ST, tops are paint. This one is 22 grams heavier than my first one which finished at 67 oz.

My stock 3.8 Mk II is 64.9 oz with Hyperion wing servos with frames and the CG at 120mm.

my 3.8 x II's are 62 oz with the standard fuze and tails - my build is lite but not crazy. You should be able to get your 3.8 to 63 without effort.

My 3.8 Xplorer2 is painted (orange) and weighs 67 with 761's in fuse and on flaps and 809's for ailerons (no frames anywhere in wing). I used the SUSA harness which added weight. CG is presently set at 120mm. I'm in the DFW area and personally wouldn't want bare carbon. It's a fantastic ship.

David, quite a few X2-3.8's are coming in at ~68oz auw including the first one in our club a few days ago. Wondering if there might be a NAN layup difference between yours and the more recent ones?
