So... I ordered a UMX Beast as my first stabilized UM plane and was wondering what to expect since I can fly helis very well and larger airplanes. I already have a bunch of 2S batteries from the 130 X that should work just fine. Thanks.

Hmmm...My Beast flew just fine out of the box. Do read up on binding and how the AS3X works as binding is a little different.
The Beast uses UMX battery connector, I don't know if your 130X batts are the same, better check on that. I believe the stock battery is UMX type180mAH. http://www.allerc.com/hyperion-g3-cx...pi-6478_0.html
I had a problem with the battery (Hype 240) rattling around in the compartment and had to wedge it in with a bit of thin foam like a foam plate foam. The Beast will keep you on your toes. I bounce it a lot on landing, so whatever you can do to correct that.
Good luck and good flying to you. Let us know how it goes.

Yes, my 130 X helicopter uses the same UMX connector. It's 2S lipo, but the batteries I have are up around 320-400mAh. I know they'll work IF the fit inside the cowling/fuse battery area. I'm just wondering if they'll fit and/or be too heavy.

My Hyp 240's are 20 x 37mm. It's the thickness that is tight. Mine are 15 mm thick with velcro. I think that about 17mm is all you'll be able to fit. Someone else has tried these bigger batteries you have and should speak up.
Good luck with you're new plane. My Beast is in the hangar while I've been flying my new Sbach. Going to get The Beast out tomorrow and compare flight.
In case you haven't seen the real Beast, may it and Bryan Jensen R.I.P. , here is a link:

Even if they fit you may have trouble getting them back far enough to get the right CG.

Ya...I forgot to mention that. Plenty of room in the compartment, but to get CG I have to slide the HYP 240's back until they are all the way past the edge of the cowl.

If you couldn't get the CG perfect, wouldn't the gyros compensate for that? Sort of like how a heli FBL controller can compensate for a slightly off CG.

To a point. Gyros help you control a tail-heavy plane but they don't do much to perk up a nose-heavy one. They can't do that magic.

The Beast is very particular about side to side CG also. My other planes, not so picky. Moving the battery 5mm forward or back I can tell the difference. 2mm to the side and I have to trim the ailerons. It flys fine with the battery forward, but I like to fly with the CG just right. Gosh forbid the battery loses grip and slides all the way back into the fuse! That's a very exciting flight.

It that really much of an issue when the battery goes right on the longitudinal centerline of the fuselage?

The batt compartment is wide and the velcro does not hold well for me. The Hyp 240's wobble at best or don't exactly sit in the center if I"m not careful.. I have to put the batt in very carefully and hold it in place by jamming in a strip of foam dinner plate. I had problems with the batt moving about or vibrating and making the AS3X unstable. any yes..If I am off a couple of mm either way of center The Beast will dip a wing in flight.

Thanks! It was a battle, for sure. The poor thing was flopping around like a fish out of water so I didn’t really have a lot of time to think too much about why. But you’re 100 right; 20x20 hindsight says “yeah, it’s the battery, stupid!”

I think that I’ve flown it so much that the Velcro is probably worn out!

I'm posting here because this is the most active thread. I may try the "mods" thread later.
I'm installing a 10A ESC that has a BEC. I'm wondering if I can power the Beast brick with this BEC through the Xport. Internal brick voltage is 4.4 and this BEC gives 5.1. The only advantage is avoiding those occasional VR shut-downs when running 3S. You know... those things where you lose it all, servos included and can only watch as your beast falls out of the sky. This has only happened to me once but it would be nice to know it won't happen again! Of course the whole brick may fry.

I removed the stock battery tray and now place the battery on the floor of the fuselage...I did have to remove some material from the foam standoffs that originally held the battery tray in place but no big deal...I glued in some industrial real Velcro in place to hold the batt...With the tray removed you can easily run 3S---There's more than enough room for 4S!!!....Not that you would want to go there...

I hit a plane-eating tree today. Like a ten foot high bush. I couldn't climb it, and it wouldn't shake down so I was forced to knock it out with a stick - OUCH!

Repairable? Probably. I am missing a pushrod, so I'll have to track that down, and it looks like it's out of stock in my neck of the woods.

EASY repair!!!...I crashed my Beast when trying 3S...Power cut and I crashed it into my roof, clipping a gutter on the way down...My Beast looked about like yours...Sure---My Beast isn't as straight as it was when new but still flies GREAT!!!...Sell the remains to me if ya don't want to attempt the repair......
