CA works fine on this type foam. I have had several EZ Stars and SkyS planes over the years and never had to cut one open. If I HAD to I still could and just use ca to glue it back. CA is brittle in some applications like mounting motors but works well in joining the fuse. Glue that expands like Gorilla glue has a tendency to "push" the joint open as it cures. You could actually just tape the fuse together and it'll would just fine. Don't over think this. Get it together and get it in the air. If you are new at this then chances are you will smash the crap out of the plane learning to fly and get a new fuse anyway before wanting to open it up for something. Do what you feel is best with any advise given. There are many fine ways to do it.

Oh, also...ca is what Multiplex recommends to glue the EZ together. Been working fine for years.
This is my second bix that i am know flying, crashed the first one beyond repair, have another in the box{the third one} going to practice my inverted, rolls and loops on this one, and damage will happen learning this stuff,{will not be satisfied untill i can do inverted 5 feet off the deck},but any who, So you think ca is the answer, gonna fly the third one stock for a while, but planto get a beefier motor for it,hence the glue question.

Best of luck to you. CA will hold the fuse and tail with whatever motor you throw at it. For the motor use something more flexible like a poly based glue or fake silicone. (real silicone will melt the foam some then harden up).
Get to handle the plane real good in normal flight until you are bored to tears before going inverted 5ft off the deck. Do your inverts high at first and start to bring them down. Your plane may last longer this way.
Best off luck.

And with that combination, it will climb straight up out of sight.

I'm pretty sure it's drawing more than 183W while it's doing it.

OTOH when I treat it more gently, I've gotten a 26-minute flight on it without running out of battery, and doing some slow climbs and a few stunts.
If you could do me a favour and please do a bench test.... maybe find out how many watts its pulling? Thanks mate!

I'll bet it isn't 705W!

Hey guys.

I am planning to maiden tomorrow but I am having cg issues. I guess the micro Dan outruner with mount puts the motor a bit rearward and my plane is tail heavy at the recommended cg of 60 mm. I am using a 2100 mah pack as far up as it will go. Since swapping out batteries is not an option for tomorrows flight I am going to add some lead to the nose ( original weight was removed).

So my question is should I stick to a cg of 60mm? Or can I push that back a bit so I have to add less lead for now.


Thanks!

3) put a carbon rod down the fuse to make it rigid. my bixler has the groove for it, but didn't come with the rod. WHY???!!!
4) replace the hardware. cheesy clevises. i prefer connecting rod anchors. that's not the proper name for them, but they are the connector that lets the rod go threw them, and locks them in place with a screw.

there are probably other mods that should be done, but these 4 are IMHO the 4 biggest gotta do mods. if there are other gotta do's please let me know.
The groove down the middle in the Bixler (aka Skysurfer V1) was for the 72 mhz antenna. Now all the radios are 2.4 ghz. It was never intended for a carbon fiber tube. Although, it is mighty nice of them to mold in the slot.

Nick,
On a maiden I'd be trying to have the CoG as close to where it should be, you want it to be as stable as possible even if it means being heavier.
But of course it all depends on your skill level.
I'd much prefer the extra overall weight than to being tail heavy.
I've not flown my Bixler yet, heck I've hardly even began the build, as I'm one of those who have 10 projects going at once!
BTW: Before StarHopper jumps down my throat, that's just 'In My Humble Opinion'.
-B!LL!

Ted said it's for a xx antenna.

That actually should be an XXX transmitter antenna. Supposedly for remote operation of my alleged 'shine still of which I know absolutely nothing about.

Full.

I'm starting to wonder if that is really a 3900kv motor or the manufacture is rating it overly optimistic.
Well, I don't have enough info to predict, since I've never full-throttled it with no prop or prop adapter mounted. Not sure how I'd measure the RPM if I did, since my tach is an optical one that works from the light flashing on the prop blades (or a flat spot on a flywheel I'd suppose).

Why do you feel the rating is overly optimistic?

70 amps thru a 40A ESC with a 2200 3s 25C LiPo, I wish!

I'll try to test it. Time to get out that WattsUpMeter I've been using on E-bikes.

Bought some foam tac yesterday, it seems i have tempted the rc gods one again.Went out for a fly this morn, botched a chuck and my bird splashed on the snowy hard ground,never did have to glue the spar covers in untill today,got home and got that repair done, went out again tried a powered take off from the snow, all was going well{did i mention that the wind picked up 24kph} untill i banked left, and mother nature said not today ron, a gust batted my plane back down to earth, as a result, got a nice big tare right underneath aft of the canopy. gonna find out how good this foam tac really is.Was in a rush to fix it{i'm a freak like that},so did not think of taking before and after pics,if any one wants pics of it fixed, be more than happy to oblige.BTW used dabs of hot glue for spar covers, foam tac for crack

Set your CG to 65mm (which will be fine) and you will need a lot less nose weight.
