Are you guys using the recomended c/g point (40mm)
Looks too far forward, it is usually very near the spar or the thickest part of the wing (70mm looks closer to me but it might be something to do with the forward sweep). I don't want to find out the hard way.
Bird: You have me worried about my brakes, I increased the "close throw" as much as pos. to hold them down. Then had to add a servo speed control to slow it down so they don't break from being slammed down so hard. Still worried, thanks for the tip I will be keeping a close eye on them.
Pete: Excuse my ignorance on the "crocs thing" it was not a dig.
I may be missing something (usually) but the motors you have linked all look a little underpowered to me.
Cheers: Kerry

I'd start out with the recomended CG.
My 2M Gerasis Fox was balanced BACK too far on the 1st Flight.
It almost did NOT make it back !
I moved the pak form over the wheel to as far FWD as possible.

OUR Foamy FOX will probably be a bit more forgiving but
my mods will tell the story.
It was WAY forward for recommended before the mod.

That HK motor is A LOT larger than it looks !
It's not just a small CAN motor at it 1st appears.

The problem with OTHER than STOCK motor will be the current mount !
It will have to be reworked a bunch to fit the longer motor in there.
At least I think so - but without actually trying.

Maybe you could put some soft foam in to cushion the Closing of the spoilers.
If they dont fall open when held upside down then they are "closed enough"

I "MAY" get another chance to fly tomorrow - if the weather guy isnt lying again !

Hey Bird, soft foam, hell ya I like it. Should be easy to incorporate. Good to have other minds thinking about our problems :-)

Re motor mounting: Someone has split the fuse and said it went fairly easy. I haven't tried it yet but if true installing a new motor mount plate should be a snap. (just an f.y.i.)

Hi Bird, it's all friendly from here, no worries :-)

My more serious stuff is 3d heli's, 2 450's, a 500 and my favourite a 600 that I call "my adreneline pump" I push it harder than the rest (3 years now, once a week) and I am still left "visibly shaking" at the end of every flight. You are right though, balance, that's why I have the foamies to relax with. I don't have a bag of money in the air and so much easier to fly :-)).

Closing the wing after spoiler install tonight ang got a wing servo sorted out and ready to glue in.
It's all good Cheers

As long as we're Having Fun - IT's all Good !

However in my case it's been raining FOR EVER !
Rain still this Am and TUE was going to be the GOOD DAY this week :-(((


Hey I'm getting pretty good flying the EC135 in FMS.
Is there anything that flys like that out there in Heli Land ?

Too cold for my skinny old butt. Waiting for spring now, might get a day here and there but not likely.

Not familiar with the ec135 but even high performance pod and boom heli's can be tuned down and set up for scale like flight. You don't have to be going crazy attempting 3D. I unfortunately, when first introduced to R/C, went to see a guy named ALLAN SZABO at the local heli fun fly. HOOKED BAD If you don't know the name, search youtube and you can watch one of the best. Not to say you can't have great loads of fun flying heli's SCALE. Here is a link to my only flying vid. Going a little easy cause I don't want to crash for the camera.
3d e-smart 600 (2 min 31 sec)
Not very impressive but I am working on it slowly. G3.5 is my best friend, it's saved me dozens of crashes I'm sure.
Also the camera guy's first attempt so you might need full screen to see what's up.

Have a good one friend, I am at work and have to get back at it.

Hey again, a little progress report.
Got the aileron servos in. Working great, a little restricted when deflected down but with differencial aileron should be fine. Made some covers with my mini vaccum former.

I'm subscribed to both but YES we ought just have one !

I have some older non Oriental Swing hinges in one of my parts drawers.
I wish they had used THEM on this bird !

Mine came in yesterday. Minor shipping damage on the wings where the root end piece is cracked a tad. Easy to fix with epoxy. The motor mounting is a disaster with all the screws out and stuck to the motor magnets and the motor/prop assembly is hanging out the end of the nose. Sounds like what others have experienced here. I love a challenge and plan to get this bird flying as well as my ST Models Fox.

I'd be afraid if I met the pilot that came with this in a dark alley. LOL

Hey Robbie
Many people are reporting shipping damage. Mine arrived with damage to the vert. stab, the foam is like soft putty at the top back. Should be easy to fix with a c/f rod or even a round toothpick or two.

Finally got the rudder servo installed in the vert. stab, now to get the wire back through the fuse. Also, I cut the hinge of the old actuater and have more deflection now (40 deg. each way. Ailerons are at about 40 deg up and 25 deg down without trimming foam at the hinge (yet).

All my Clean Living finally paid off as MY Fox had no damage at all.

The motor was even Difficult to get out to look at.

Go figure !

Then Again ...

1. I am on the west coast so Very Little USPS handling.
2. I have had some very bad luck with the CA post !

Point being are the Chinese beating it up ? - I think NOT !
Are some militant, unionized, USPS workers NOT playing nice ? - YOU make the call !

I used to ship out all over the country and had maybe >5% shipping damage problems.
So I jacked up the price and started INSURING all the packages.
NO damage SINCE I started insuring.
IS THIS a Coincidence ? I think NOT !
