I was lucky enough to get one of these this week.
48" molded. Lots of carbon. Stiff. Not much room for gear.
The wing and front of fuse are molded in one piece with a separate nosecone. The tailboom and fin are also one piece mounted just behind the wing TE. The tail is not yet mounted so it might not be square in the pics.

I got this used but in excellent shape.
AUW: 36.5oz
CG: 80mm
MKS 6100's all around on a 4 cell AA Eneloop pack with Spektrum "Carbon Fuselage" receiver.
I was going to switch to a Hitec rec'r but it doesn't really fit anywhere so the project stalled until recently when I bit the bullet and bought a Gen 2 DX8 radio.
Programming and channel setup is odd but I'm getting there.

Update: Plane flew great this past weekend. Zero clicks of any trim needed and crow settings were good. Plane flies great on the front side with a predictable stall unless you are really yanking on the ele with high rates.
DS was smooth with very little balloning at higher speeds.
I took a few landing approaches but got her down safely. Still need to get used to using my left thumb.

Time to start on JW #2 in my Quick Build series. I'm pretty sure this one wont be finished for the Spring season.

Like the others, this one will be built from the JW "Classic" kit available from jwglider.com.
Standard sized servos: Tower Hobbies TS-64 (OEM versions of the now discontinued Hitec HS 635).
4 cell AA nimh battery pack, also from Tower.
2 layers of Bidi strapping tape and a simple covering design using Hobby King covering.
The fin will be the stock coroplast and the balsa elevons will probably not be glassed.
This one will be built with the stock carbon tubes instead of the solid fiberglass rod spars used on #1 build.
Target weight is around 50oz.

I picked up a DM8 Spektrum module for Futaba a few months ago and finally got an antenna and replacement antenna mount to fit it in my 9C.
I've got a few things to test out with it including my Gyro Bee and a Sunbird.
I couldn't find any pics on the web showing what this setup looked like and what exactly was needed.

After seeing Aaron and Bruce fly their Tweety JW's I knew I had to have one.
Then I got a chance to fly Bruce's this past week and started to get the build ready the day I got back.
Extremely stable plane for its size.

Specs:
4 cell AAA battery in the fuse
MKS 6100 servos
extra bottom spar
carbon TE
Hoping to squeeze in a Hitec Optima 6 rec'r
2-3 layers of 3M extreme BiDi tape
Hobby King covering.

This is a Prototype build using JW wing cores cut to a 30 leading edge sweep.
I'm going to try and build it similar to my 40oz Bee and Rebel DS wings to compare DS and strong wind frontside performance.

Specs:
48" span using 30 sweptback JW cores
Stock JW spar system with custom joiners. 4 piece .240" carbon tube.
Carbon TE
Additional carbon spar to make an A-frame
5 cell AA battery pack
Std sized Hitec analog servos with Karbonite gears. Actually Tower branded TS-64
Hitec 6 channel Optima receiver
3 layers of 3M extreme bidirectional tape
2mm Coroplast winglets
4-40 hardware
Probably going with FG bagged elevons

This is an oldie but I replaced the battery this week and wanted to post the build specs for future reference before I forgot them...
  • JW60 Standard (Classic) kit.
  • Hitec HS 5475 Std sized digital servos
  • 5 cell 2/3/A sized battery pack in the fuse. I'll avoid these in the future and stick with AA Eneloops.
  • fully taped and gooped fuse. Goop tinted with Testor's enamel
  • 2 layers of extreme tape on the bias
  • balsa fin (replaced a few years ago)
  • fixed TE 6" in and out board.
  • 2-56 hardware
  • bottom hinged
  • carbon sub TE
  • layer of goop on spackled foam and over last layer of tape
  • Monokote covering
Top speed was 177 IIRC, if it was blowing I usually put up a heavier JW.
Up close it has a bit more of a textured surface compared to my other builds that usually have 1 or 2 more tape layers.
Other than that, I think it was one of my best builds and it flies well.
Oh, I also ended up drilling and pinning (with .080" FG) the bottom spars and joiner when they loosened up. I had used Mercury rubberized CA and it let go... JB weld from now on!
When she was young , fast, and pretty...


and now the old lady looks like this..

I need a replacement for my Gyro Bee that I killed a few months ago.
I'm trying very hard to build this one simple, cheap and lightish.
Target weight is 30oz.
Build Specs:
Bee II cores
Std Hitec servos: HS 425's.
4 cell AA Sanyo Flat pack.
upgrade to .25" Fiberglass rod to replace the std carbon tube spar
.080" fg rod arched I-beam in stock location.
5mm x 1mm carbon ribbon sub TE spar.
Strapping tape: approx 2 full layers of standard 3" Bee tape.
thinned goop
spackle used sparingly
Oversized 2mm coroplast winglets
balsa wingtips (not winglets)
Orange Gyro/Rec'r

I'm starting on a plan to build 3 JWs by next Spring. The idea is to develop a quicker building, lower cost, lower weight, more versatile airframe than my usual efforts.

All three will be built from the JW "Classic" kit available from jwglider.com.
They will use standard sized servos and 4 cell AA nimh battery packs.
The current plan is to use only 2 layers of strapping tape and a simple covering design using Hobby King covering.
The fin will be the stock coroplast and the balsa elevons will probably not be glassed.
One difference is I will be building the first one with solid fiberglass rod spars instead of the stock carbon tube spars to prove if they are stiff enough and without a significant weight penalty for use in future builds.

I was lucky enough to get one of these awesome planes a few month ago. I've only flown it twice with speeds less than 200.
This one is a lighter version. MKS 6125's with third bearing support frames, 4 cell AA battery in the nose. Quite an amazing plane and good looking in the air.

Started on a JW36 this weekend while waiting for spackle to dry on my Sonic.
The fuse was sanded round, thin gooped, and spackled.
4 pc .080 FG rods used for reinforcements.
I also cut out the noseweight bay using my standard method.
Pic is before I cut it out.

This Moth was one of my first foamies. I loved this plane but constant rec'r problems (Berg) cause it's premature demise... twice.
I shelved it at least 5 years ago (edit: almost 8 years ago!). The fuse became a test for improving my "goop fuse" process and it came out beautiful. I knew it would no longer be a lightweight so I fully enclosed the sides and left only an access hole in the leading edge cutout. This meant all radio gear would go in the wing. At the time I was still using 72Mhz Electron rec'rs and they wouldn't fit. I ended up installing a Corona but then ripped it out last year and dropped in an Optima 2.4. New Hs-85s were moved further out and a custom 4 cell AAA pack was ordered from CanuckEngineering. I also added some spar reinforcements and a carbon TE. The elevons were reused, filled and glassed. The linkages are over/under style.
So much foam was missing from the rebuild that half this wing must be half spackle. It looks nice now but won't survive abuse, I'm sure.
I'm not expecting a 200MPH plane but will be happy if it flies nice up to around 150-175.
Current weight is 37oz but it looks like it might take 9oz to balance at the conservative 1.5" recommended CG.
Edit: AUW 46....Continue Reading

Aaron over at jwglider has recently re-released the classic Bowman Sonic.
This one will be be built for medium DS. I'm not going for a record build just want one of similar weight to my DS Bees which are about 44-45oz.
Edit: AUW is approx 55oz. Must be due to less sweep and heavier main spar behind the CG.
I'm starting now with hopes that it will be ready by Thanksgiving.

Specs:
5 cell AA Eneloop flat pack
Hitec Optima 6 channel 2.4 with battery telemetry.
Standard Sized Tower TS-64 servos. These are the old and excellent Hitec HS-635 Karbonite gear BB servos as far as I can tell.
.240 Solid carbon rods in stock location
.220x.092" Carbon subTE spars
3 layers of strapping tape
Monokote /Ultracote/HobbyKing covering. Edit: only HK covering was used with Ultracote flames.
Oversized "Bee Style" winglets
Fiberglass bagged balsa elevons
4-40 linkages

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




Here is the extra spar slot I mentioned above. I bought a 6 pack of these when Ming switched production to the Bee II.

After reading a few threads on cheapo vacuum bagging techniques I decided to give it a try on some Bee elevons.

I bought a food saver at Costco a few months ago to actually use in the kitchen with an idea in the back of that my head that I might be able to use it for bagging fins or elevons. I had come across several mentions of the technique in RCG.

The food saver came with a 10 foot roll of 11 inch wide bag material. It has one smooth side and one textured side to help with the vacuum. I had already purchased a quart of West Systems epoxy on Amazon several years ago for finishing out a few molded planes. My local plastics store sells fiberglass cloth by the yard. I bought 2 yards of 6 ounce cloth for about 15 bucks.
In some of the threads I read about using dry erase instead of mylars. After talking to a couple friends while flying they suggested I simply use plastic sheeting from Home Depot, I was wary but willing to give it a try.
I bought some 4 mil. I also bought a few cheap disposable paintbrushes. I was concerned about the brush is losing it's bristles so I CA'd the bristles into the ferrule.
I thought about it for another few weeks and then decided I had stalled long enough, it was time to give it a shot.
I cut a 6 inch wide by 30+" long piece of 4mil plastic sheet. Then 2 pieces of glass cloth approx the same size but on the cloth's bias.

Next I made a bag long enough to fit it all in including a few sheets of paper towel...Continue Reading
