Nice Stu, do you put more goop over the covering after that? I have to build myself another foamy- maybe a beevo is a good way to go.
Cheers, Josh

Is this a Bee, or bee-evolution?

Thanks, Colby

This is an original Bee kit. I bought a bunch of them when the prices for the new ones started to get expensive.
I've used goop over the covering in the past but now I prefer not to. It's easier to fix. Add a 2-4" strip of New Stuff and this thing is ready for the furball.

The Beevo is kind of an odd plane. It is significantly thinner than the Bee, which is already
one of the thinnest wings out there, and this makes it slippery and quick in smooth air, but when
it gets a bit rough the Beevo slows right down. It very inefficient at high angles of attack.
Makes it not very good at combat or DS, so from my perspective, pretty worthless.
A heavy Bee is plenty fast, as Stu has proven.

And I agree. I used to Goop the leading edge. Now I use strips of 10mil laminate (the softer variant).
I also like to add a couple semi-circular plates of NS to the top and bottom of the nose (they
go on first, and the LE strips overlap it), for added impact and anti-fold protection.

Oh perfect! So the Beevo I ordered should be perfect for our rough nasty air at POTM and Eagle Mtn. Bummed out...

I still like my BeEvo very much even though it's beat to heck. I built it pretty much standard Predator style except a AA 4 cell and a custom strapping tape job. I think top speed was 128 at 27oz. I run the CG maybe 8-3/8" and my elevons are about 1-2" too short ( I screwed up and made 2 identical instead of L & R)
One thing I'm not great at is comparing different flight characteristics. Ian might be a little too harsh on the old gal.
One day soon I will make a 40oz BeEvo and compare the two or anyone who meets me on the hill can do their own comparison.

Thats news to me about the beevo being not too flash. I only know one guy with a nice weighty one but it seems really fast (not that Ive compared it to a standard bee though)
BTW they are doing free shipping at the moment so I might just have to get one. I do like the bats though- maybe I need one of each!

My 32 oz Beevo was fast and fun in good wind, but in lighter conditions it was not flying. It was too heavy for combat and even in strong lift, did not recover well. I like a lightweight Bee2 in the sub 20 oz range for combat and I'm building my 3rd one now. Since I split the Beevo up the middle, I need to get cracking on another heavy Bee2 for DS.

Keep in mind, some of our best DS days on Zion, would be considered almost unflyable
at Weldon. In our rough groove, I've found a Bee to handle it better and maintain its energy.
Where it *really* shows though is in combat. Almost everyone here flies Bees
and we swat at each other constantly and the Bee just keeps going at a consistent pace.
Take a couple swats with the Beevo (which is definitely faster in a straight line) and it slows to
a crawl and the Bees run away. It just does not fly at high angles of attack.
And after a combat hit, forget it. It just tumbles out of the sky (for the same reason).

So what is the magic AUW to shoot for then on a Bee?

I'm really liking it at 40oz for anything over 15mph.
25-30oz is too light.
70oz is not too versatile.
I flew mine again on Sunday and it outperformed my medium heavy 60" LEG 109.

I have a 10.5 oz Bee, a 20 oz Bee, and a 35 oz Bee. The wind range that's most fun for me for each plane is:

10 Oz: 4-15 mph
20 Oz: 7 to 30 mph
35 Oz: 12-40+ mph

I have found that the optimal CG shifts back with weight. 8.5" is perfect for the usual 18-20 Oz Bee, but my light one was a little unstable at that location, and my heavy one was too nose-heavy with that CG. At 35 oz, the Bee has to be flown pretty fast to avoid tip stalls, and it lands hard, so you really have to ballast up with tape and coverings that add strength in order to keep it from being too fragile. If you only have 1 Bee, and you want to fly on moderate days, I'd go for 18-22 oz. That's a pretty standard speed for combat where I fly, too.

I agree with your wind speeds/weights.
I like a normal Bee as well but for DS or big air the heavy Bee is still my recommendation.
Also, my CG experience is almost exactly opposite of yours.
My full trailing edged 70oz Bee tracks poorly with the CG at 8.5". I moved it forward about 1/8-1/4".
Still no additional tipstalling tendencies.

My Bee came in at 100 oz.....is what I would be telling you had I built it the way I intended. But now I am rethinking the build to get the weight down.

So I have started a BeeVolution for a local guy who wants a nice first DS Model.

The cores are very warped and not even. Hollow spots etc. Any advice with keeping them somewhere of respectable during the build? Should I weight it flat along the TE and rear part of the chord in the upright position?

I have replaced the stock 1/4" carbon/fiberglass joining tube with a length of 1/4" spring steel rod, and then added the two 3x1 carbon pieces in the arc top and bottom as Stu did. Next is some 6x1 carbon for the TE.

Should I put any more spars in? Or will the Fiber Tape/Lam Film be enough over the top?

Aim is for a 150mph capable BeeVo, so around the 40oz mark

6v Eneloop, HS5485HB servos.

Stu, did you fix any part of the trailing edge? Or have full span elevons?
