I forgot to post this one. I finished it last year but was skunked at several attempts to maiden. This is my heaviest JW yet at 105oz. It's still a single spar kit but I upgraded to solid carbon rod and carbon subTE spars.
I've switched to using the fluoro on the flames to help see the wing when it's coming at me. It helps.
I got it to 200mph last month so I'm happy. I think that makes it 4 of my JW builds that have gone at least that fast. I think there's more in it if I can keep it together.

Here's a great little 24" plane now being sold through Matin at NCFM.
The Half Bad.
I'm not really happy with my build on this one and it still needs some tweaking to get if flying well. Other folks are flying them from light to really heavy. I have another kit so we will see...

I wanted to see what would happen if I built a Windrider Bee capable of 200MPH. I'm not sure it will go that fast but didn't want the build to hold it back.
The results...
70oz
4 layers of 3M 8959
Carbon Sub TE spar
Standard Tube Spar with steel rod insert
Leading edge I-Beam config carbon rods
Ribbon spar
5 cell AA pack
Standard Hitec Digital servos moved out to 9.5" from CL
Full TE w 4" fixed inboard and out.
4-40 linkages.
Spruce and balsa winglets
NO Laminate Film!!.
NO glassed or carbon elevons.
CG has been tested at the usual 8-1/2" but it's much more stable at 8-1/4". Inverted flight is still good but I'm going to have to do some tweaking.

Speeds: Maiden 166MPH at Weldon.
200? Maybe.

UPDATE: 2/19/13 - Got the Bee up to 190 at Weldon in winds 30-42. Really felt good just when I was about to rip off the fixed trailing edges and start over.

UPDATE: 5/26/13 - I broke 200 at Weldon in really smooth winds 30-50mph.
Final speed was 204mph. Really happy with the performance of the Bee. Pretty cool to do a punch-out to speck altitude in about 5 seconds.
The general consensus is I need to bag the elevons if I want to go any faster, they are quite flexible even cut down and covered with strapping tape.
