New Bird COMPLETED
This Proud Bird (Q-40) fuse just hatched this morning................not even trimmed yet. Still have to do the wing, stab, pan, and cover.
The Neme-Q fuse (Q-500) is one I pulled last week.

RE: New Bird
Why, yes! Nice plug, nice molds. Someone needs to dust off that plug and make another set of molds so I don't have to give this set back so quickly.....
I should get a keg of epoxy and splash those wing molds, eh?

RE: New Bird
Make two sets and send one to me! All that time into the plug and I've only had two fuses out of it...LOL
By the way, that's a BRIGHT yellow..I like it, but I'm sticking with my current color scheme....

RE: New Bird
It's one of the PB designs at the Nats. Jim Allen and Scott McAfee are flying them. Mike Tallman and Jerry Elert may be as well, I know they have them, but not sure if they're using them.

RE: New Bird
GS,
Did the cover and pan last night, will prep skins tonight, should have wing and stab bagged before the weekend and out before Monday. In the meantime I've got to get the fuse molds ready and painted for another layup on Saturday.
This may not BE production, but it's sure starting to feel like it!

RE: New Bird
Not the prettiest or the lightest (31 ounces) but I believe it'll be flyable. The first one's usually an experiment. It took 10 days from cutting the masks to all pieces out of the molds and that includes a lot of head-scratching. I'm hoping to do the next one in less than 7 days.
It's the first time I've used this paint and I didn't know what the colors would look like together. The checks and fuse lettering are a dark blue but actually look to be black. Same goes for the lettering on the bottom of the wing; the backshading is black and the letters are blue but they all look like the same color. I'll have to lighten it up a shade or two for the next one. The checks on the tail were supposed to be on the top, too. I painted it before realizing that I masked the wrong side. Duh! The lettering on the side of the fuse could have been bigger, too. As I said, lots of learning.
Time to "karate kid" for the next one ("wax on, wax off. wax on, wax off.)

RE: New Bird COMPLETED
Looks good Tony! Although I think you're a masochist with those small checks done in the mold, I would've done larger checks so I don't have to peel them all out....
The weight will come down as you do more. The first wing Jim pulled out of the mold was about 22 ounces, and as you know, they're pretty much all under 16 now....31 ounces doesn't sound that bad, although I don't know what ours typically run at that stage of the build. I know we used to shoot for about a pound and a half for a framed/monokoted Q500 to make the 3.5 minimum. If the fuse and tail are heavy, it will probably want to come out tailheavy, so you may end up with the battery in front of the fuel take (not too hard since the tank's on the CG, and the nose is empty anyways), maybe even put the servos farther forward if you can....

RE: New Bird COMPLETED
I think it'll be OK regarding weight and balance; fuse is 8.4 oz, tail is less than 2. The wing alone is 4 ounces heavier than it needs to be. Then again, I've purchased commercially-available wings that weighed 19 ounces before painting. Mine's probably not all that bad. We'll see.........

RE: New Bird COMPLETED
Nice job Tony. I really like the glow in the dark yellow.Like Gary said, they only get lighter with esperience. The more you do the better they get. If you don't mind me asking, what paint are you using and what resin are you using in your layup?
Again, well done, Arch Adamisin

RE: New Bird COMPLETED
Arch,
Paint is PPG "DCC", resin is MGS. The fellow I borrowed the molds from has had great success with both so I just used what he recommended. I must say I'm happy with both.
The only caution when using that paint is that it dries quickly and you must peel the masks almost immediately in order to get clean edges. If you can't pull imediately, then pull REALLY SLOWLY. Immediately is better, though.

RE: New Bird COMPLETED
Fuse #2 etc., wing cookin', stab's joined. Bigger and different font than on the last one, lighter blue. I'll never do checks on a fin again (argh!)
Yes, I think I might have used a bit too much epoxy for the wing layup. LOTS of bleed through into the breather. At least it's in the right spots (spar caps and gear pads).
Should be able to join the wing tomorrow night.

RE: New Bird COMPLETED
Tony,
What kind of Vacuum are you able to pull with that pump?
I ended up getting rid of mine like that and picked up a gast pump that could pull 20", my Aerospace one could only pull 15", which isn't enough in my opinion.

RE: New Bird COMPLETED
I can get about 18" with the Aerospace pump but I added a "regular" (rotary vane) vacuum pump and the whole system gets down to about 24" . I've got the pressure switch set so the Aerospace Composites pump shuts of at about 15" and the other pump runs continuously. I left the Aerospace pump in there as a failsafe, to use the vacuum reservoir, and to use the gauge. You can see the 2nd pump in the background. It's some type of Chinese "hobbyist" pump for A/C or HVAC repair that I got on eBay for about $75.

RE: New Bird COMPLETED
Finally finished the first one and flew it today. All went well.
I expected the first one to be heavy, but it's only 2 ounces over minimum even with a 700 mAh battery pack. I can live with that.
