Here's an update on my original 40ozer:
I started to have radio glitches with my old 72Mhz rec'r and pounded it one too many times into the hill.
Bruce was more than happy to slap some tape and new winglets on it and flew the cr@p out of it for awhile. I'm told the wing folded countless times.
Finally he repaired the broken main spar and added glassed elevons and plywood winglets.
Rumor has it he added a few more oz of ballast as well.
The damn thing flies better than ever. It's probably been faster but he clocked a 166 the day I saw it. I did a few laps and it really carries it's weight.
Bruce says he may add another layer of lam down the road but it's hard to mess with perfect.

One more thing...Bruce top hinged these elevons so between that and the wood winglets, it eliminates 2 possible causes for the Bee whistle. We are now suspecting the area between the elevons as the source.

A couple vids.

Stu's Bees are simply spectacular. You put in so much time building and it shows. Even after damage, your planes are still really clean. We can aspire to build like you!

Forgot to update this thread when I finished my latest...
WindRider Bee - DS - 45.5oz - Fiberglass bagged elevons

9-1-2015
This is the 4th of my "40oz Bee" series builds.
Again, this is not built for outright speed but for DS furballs and general DSing. I expect top speed to be under 170 and in the 100-150 range.
The kit is an old Bee with an extra exposed spar slot on the top of the wing.
It's also the first DS combat wing I've built with fiberglass bagged elevons.
I hope to maiden this weekend.
See my other blog posts for build threads and pics of this style build.

Here are the specs:

5 cell batt pack
4 - .080" Fiberglass rod spars.
.25 Solid FG rod in stock location
extra spar in the exposed spar slot, I think it was the stock carbon tube spar
.22" Carbon subTE spar
Standard Hitec HS-425 servos moved outboard and just in front of the stock spar location
3 layers of strapping tape
Monokote/Ultracote and Hobbyking covering
Oversized winglets
Upgraded balsa elevons bagged in 6oz fiberglass cloth cut on the bias,
4-40 linkages

Okay I'm back from my DS Safari.
I was lucky to get 4 days of decent wind ranging from 20-40mph.
For the maiden I added a 1/2oz of stick on weight to the nose as the CG seemed just a little too far back for comfort. I had a bit of excitement when I maidened the BeEvo and didn't want anymore. The launch was good, I needed quite a few clicks of down and left trim but CG was close. Inverted was good. Elevator and aileron throws were good enough as well. I DSed a few laps and did some punch outs to test CG. Landed and pulled 1/4oz off, then added a turn to one clevis and a half turn to the other and re centered the trims. Second flight still needed a few clicks of down but CG was closer. Landed and removed all the stick-on weight. Also added a half turn to both clevises. The next flight was very good, it did not show CG that was too far back. Now it was time to dial in max elevator to remove any chance of a flick. I ended up at about 24% up elevator and 28% down. For high-speed DS I added 2% to compensate for elevon flex. I had quite a few more flights and I'm very happy. I can't remember exactly but I think top speed was only about 130.
