Xfly Models B1B Bomber 70mm

IMPORTANT SAFETY ISSUE.

Check out this post on RCG:

https://www.rcgroups.com/forums/showpost.php?p=51226085&postcount=1778

It shows a failure of the sweep arm on the wing where the sweep ball joint attaches, with paint or crazing showing on the fracture surface.

This shows that a crack was present much of the way through the part before the part was installed, and was an accident waiting to happen.

I checked mine and it has the exact same defect.

This is a safety of flight issue and needs to be thoroughly investigated.

Congrats! Yeah she's actually a trainer disguised as a bad ass bomber.

[kallend]

Despite the best efforts of the Canadian forest fires, I got the maiden done today. Visibility was very poor.

Didn't sweep the wings. It flies like an advanced trainer, very smooth and no vices that I detected. CG at 81mm (wings forward). "Bypass" mode.

Have u watched rc plane reviewer ,, had his own troubles,, like many..... looks like alot of up mix req folding wings.... shifts cg..... not req on fwi g f-14 .....?.

I said it in the other build thread on RCG but I stand firm in my belief that Freewing would have tackled these issues differently. Yes, yes, call me a Freewing Fanboy but they've been world leaders in EPO warbirds and jets for many years so I feel confident in my opinion. No, they are not perfect, we saw that with the sub-par servo issues in recent years but they are about as good as you are going to get at the moment when it comes to manufacturing these jets and warbirds we love.

Having said that, I absolutely LOVE the competition. I am very, very grateful for XFly, and others. It keeps everyone "on the ball" which ultimately leads to a better product for us as consumers and flyers of these models.

It's also a reminder why Hobby Squawk (obviously owned and operated by Motion RC) is such a great place...Even if we don't sell the model, we know the importance of inclusivity...It really doesn't matter who produces or distributes a new model...We are all lovers of aviation and RC flying, period. I will always have my personal opinions and affinity towards certain brands of course, like anyone else, but the bottom line is we all want the same thing. A beautiful model that is engineered marvelously, scale, and delivered with flight dynamics we can all stand behind.

I am just happy someone brought the B-1 to the market! She's a gorgeous gal!

Look how much elevator he had to add to fly with the wings swept @19:50.

Well, he told us just how much up trim ("negative 80") but that information is useless because (1) we don't know where he started, was it at zero or some other amount with the wings forward (2) what were the units? On a Spektrum the units of subtrim, for example, do not map 1:1 to units on the +100% to -100% scale of the channel output. (3) how much trim you need depends on where the CG is, and he didn't ever tell us that, and (4) not everyone flies Spektrum.

So all things considered there was some nice flying in the video but it was pretty useless as a review.

Excellent advice Captain my Captain.

Aros, I have no clue about your 'touch up' color, but as for spackle or filler, I've been using Sherwin Williams "Shrink Free Spackling" ($7.00 USD +/- for 32 oz) as per Chris Wolfe (The R/C Geek). I like it, though I over fill the blemishes and dry sand back to the surface once the filler dries (30 minutes tops usually) I then lightly brush 2 or so coats on the area with Minwax Semi Gloss Clear Acrylic. Anything type will do here to seal it. Let that cure 4-6 hours then wet sand, prime, wet sand, color coat. Make sense? Works well if you want that OEM finish, otherwise skip the prime coats and go straight to color. Best, LB

[Aros]

Anyone have the color codes for the paint match by chance? I got some hangar rash from transporting...Speaking of, what's the best spackle-type fix for EPO foam? I've used all kinds of things but nothing that makes me say YES! That's it!

I see my V wing B-1 made the front page of RCG.

Dont think he had an adapter

[Evan D]

We was joking.... I don't use adapters but they are safer than plugging a XT90 into a EC5, BTW a XT60 in a EC3 is okay, they have the same size bullets in them.

[Aros]

Dang that's a lot of up mix in sweep wing mode!

So even with an XT90/EC5 adapter it could overheat??

[Evan D]

If he added afterburners....

[kallend]

Look how much elevator he had to add to fly with the wings swept @19:50.

No doubt due to using an EC5 with the XT90.

I’ll say it once more XT and EC are not compatible and if you decide to plug one into the other it’s a stupid decision. Kallend said in a pinch you can spread the pin to make a better connection but DON’T DO IT. In the picture are two types of pins used, these are both EC5 pins. The one on the left is what he’s saying to spread and yes I guess if you did it would make a connection but it’s just not designed to be used that way. I can’t believe a professor actual even suggested it. What’s next, missing that machine screw to hold your wings on, use a wood screw, it’s close enough?

You'll love this bit of the video:

That's too handsome.

Probably true!

Well I’m picking one up on Monday. My plan is to bypass the stock gyro and put it on a S8R and use one 1-4 subs extender.
I may or may not ever use the gyro function in the S8R, but at least it will be there if I need.
My ch layout will be 1:Ail1, 2:elv, 3:throt, 4:rud, 5:ail2, 6:gear, 7:flaps, 8:ster, 9:gyr, 10:mode1, 11:mode2, 12:calib, 13:wing, 14: rev.

I want to play around with adding some up ailerons while wings folded back to maybe take some of the up nose up load off the elevator. I’ll put it on a switch so after I get her flying and trimmed in both wings back and out modes, I can then added it in to see if she climbs, does nothing or dives.

cant wait
