I think the black/green actually looks really cool.
To bad the sun would wreck it in that state.

your first fuse is really beautiful!!!! Great job! The MkII version is (on my mind) really better in shapes than the first version (but it's personal).
I love this plane too
See you

Thanks,

Robert

The total fuselage weight comes to 32oz. Not what I was hoping for, so I'll have to make some adjustment on material.
I'd be interested in hearing fuselage weights from anyone willing to give them. I'd be interested in knowing weights of the ZN Twister, Brio, Genesis (builders versions).


Thanks,
Todd

I have weighed 2 Genesis (kit) fuses. One is fiberglass and one is glass/carbon fiber. The weights (in ounces) are:

---- fiberglass ////// fiberglass/carbon fiber
canopy ---- 4.0 ////// 3.3
chin cowl ---- 3.0 ///// 2.0
fuselage ---- 21.8 ///// 20.5

total ---- 28.8 ////// 25.8



I also have another glass/carbon fiber kit that is maybe 1oz heavier than this one.

Hope this helps.

Sorry but the formatting got messed up when it posed

Twister is about 27 oz, including canopy and chin cowl.

It uses much less carbon than you have, only comes back maybe 12" from the nose. Your foam looks thicker as well or is it just the pics? 1/8" is in all ZN kits.

If memory serves me correctly the ZN fuses are laid up, 2 oz glass, 1.8 oz kevlar/2.8 oz carbon, 1/8" foam, 2 oz glass.

I may be off on the 2 oz glass it might be a bit lighter but its close to that.

Thanks a bunch for the input its greatly appreciated. My first layer down was 3.1oz crowsfoot glass. It works really nice but I suspect it holds to much resin. I used used 2oz. cloth on my Def1's and will go back to that on the next layup.

I think I'll try this on the next one:

2oz cloth
1.7 Kevlar
2.9 carbon (not as far back this time)
1/8 in foam covered with .75 or 1oz cloth (and go into the top deck)

I noticed the twister Canopy is Kevlar and will go that way too. (my Def1 canopys were made that way and turned out well)

We'll see what happens, I'll keep you posted, and again, thanks for your help.

Todd

Status: offline 		Hey Todd, that weight is not bad at all, you can still get that plane to weigh under ten pounds, even with the fuz at 32 oz. I would not throw away that fuz. I suppose if you are not going to use it, I sure will take it off your hands

Status: offline 		Just a note to say thanks to everyone for information and comments on this thread. It's great to get the help I need so quick. I know the weight could be better on this fuse and will be laying another up this weekend.
Whats encouraging is the information I've gotten from some friends. It seems this weight isn't to far off from a lot of fuselages on the market. My brother has an Impulse @ 31.5oz and another friend's Temptation fuse was the same. These planes are being built well within the weight as Robert states. Sorry Robert I'll probably build this fuselage.


Thanks again everyone!

Todd Schmidt

Status: offline 		Todd,

If I remember correctly, the PL Partner was 19 ounces for bare fuse, canopy, chin piece. It felt unbelievably light for its size when I held it in my hands. However, the honeycomb pipe tunnel and internal formers, stab tube, firewall started increasing the weight. The ready to paint weight with everything on it, wing tube supports, all the things I mentioned was 830 grams, or about 29 ounces. As light as it is, it is not a fragile product. The ready to fly weight of this plane with DZ 140 is 9.75 pounds. My ZNline Supreme fuse was 859 grams ready to paint, but the final weight with OS 140 RX is 9.0 pounds. The paint, covering, landing gear, and engine setup contributed to the lighter final weight. I hope this is useful information for comparison.

Your mold is a work of art. I am very impressed.

David

Your plane is looking Bodacious!. Great workmanship and effort. The couple of tweaks in the next one should be awesome. I weighed my Prestige (electric version) and it is 28.10 ounces with firewall and landing gear plates in.

Would I be able to use my West systems #105 resin (Which is an Epoxy finish resin) to make this Paste that you have made here..?? If so, what was the material that you used for the thickiner and the tint..?? And unless I missed it, you didn't say just how much glass/resin went over the first half of the plug to form the mold, before you flipped it and went on to the second half..??

And do you get most of your materials off of t
