Had to put a bit of weight on the front to balance them level. did that on my other planes with the wing too. Didn't get a chance to fly it today as I was helping an other buddy get his glow engine going and accidently stuck my fingers in the prop You'd think after 76 yrs i'd learn Took 8 stitches and when I got back it was too dark. Bummer. Supposed to snow tomorrow so we'll have to wait.

+1 when I get my replacement B3D The first things I'll do is reinforce the wing roots, break off the battery hatch tab and replace with a tiny flat CF strip, reinforce the elevator joiner, and finally add heatsinks for worry free 3S operation.

Bob,

The foam tab measures.

+1 on removing the foam tab on the battery hatch and replacing it with a small carbon strip. Solved the problems I had using some batteries.

You don't even have to replace it. It stays on fine with no tab.

Got a dumb question. I bought a UMX beast that one servo did not work (rudder) and a second one that was crashed and the foam was MESSED UP but the electronics were ok.

Put them together but no stabilization like before?? did they make these WITHOUT the as3x system at one point?? or is there some way it is turned off or something??

Thanks

Yup, V1 (gold trim) = non AS3X;V2 (silver trim) - AS3X

If the 'brick is good, you can swap it -- physically mounts the same.

About ten or ten thirty today, we all had quit flying -- just too breezy to be fun, even my Stryker, and the jets. While we were standing around chatting, one of the fellas mentioned the UMX Beast, and it's supposed wind handling. I asked him if he ever saw one, and he said nope only flew it on the sim. I asked a different member to check the field with his anemometer and it was a steady 20, with gusts bigger. I have flown the Beast in 10 and 15, but never this much. I thought, what the heck, we are just sitting here anyway... so I took mine out, and launched it. No video, but it was able to do the usual complement of rolls, loops, etc, except that moving down wind I had to stop it before it got too far, and coming upwind, it took a while to re-establish ground position. I kept it higher than ten feet to be sure not to suddenly slam the ground in a downdraft, but after four minutes of pretty well controlled flight, I was able to just slowly hover it down to a parking spot in the grass. Can't say it was particularly fun, or that I'll do it again, but it;'s good to know the old Beast can really handle it!

Does the plane fly the same or close to it after repairs? Was a little too comfortable with it during lunch and was doing some maneuvers too close to the deck. Had the lower wing ripped halfway off on one side and the upper one halfway gone on the other side. One aileron servo pulled loose along with several of the cables. I believe I will be able to mend it all up, but it sure didn't look good when I brought it in.

I was just stunned when I did it. The margin between great flying and looking foolish can be pretty small apparently.

If you get everything right, it doesn't matter how may repairs or replacement parts on on it!

Mine has wings from one plane, tail from another, fuse from HH spares, changed motor, prop, ail servos moved to top of wing, etc, etc etc.

So mine has been through the wringer and back again, but I feel it flies almost as sharp as day one out of the box.

As long as you get the basics right -- everything squared up, don't change angle of incidence, don't have weak/torn surfaces that flap or distort, etc, then this thing is just awesome -- you have all that wing area, all that frontal area, and all that tractor-like power to pull it trough the air -- it flies just like the big brother Model 12.

Sorry your plane got bashed. My Beast went through a period where I would have sworn it had a death wish. Ripped the wings up so many times I was repairing the repairs. I bought a new wing kit and rebuilt it, a bit of touch up paint and my Beast is good as new flight wise. I have more respect and better understanding of the airframe now that I have put so much time into it. Patch your plane up, take your time and get it right and you will have an awesome and custom plane!
Foam-Tac foam glue is the bomb BTW. Foam safe CA just seems so brittle, but has it's place on plastic and carbon fiber repairs.
I have a lot more strength in my wings now because I added packing tape on both sides of the black wing supports. The ones about an inch wide that go vertically from bottom wing to top. They are so fragile I bent them just gluing them on. Encased it packing tape they are much stronger.
Good luck with your re-build.
Mike
