Dear Puffin's Through (PT) and all you other quitters,
Hooray for us!!!
Stick to it big guy (and I mean that in the nicest possible way).
I had my last ciggy on Cinco de Mayo (Mexican day celebrating eggs and oil) 1975.
An incident that made it easier for me to stay "straight" was when a "chewer" dropped the tin can he had been filling for a couple of days in a fairly crowded establishment that served "liquid refreshments". Two women immediately threw up quite messily. One extremely handsome, intelligent, and charming gentleman who was standing nearby also came close to purging himself (three guesses).
I also have a friend who had part of his tongue removed due to cancer and chewing and snuff. Good stuff to stay away from.
I meant for the above to help keep you hanging in there. I hope I didn't offend anyone by this off-subject entry but only those of us who have gone though it can relate to how tough it is.
OK, on-subject, I predict that my TD .020 delta will come close to 7 ounces RTF.

Raymond, I'm wiping the tears of my face after reading that. I would have joined the women quickly. I used to dip snuff till I hopped in my van one day and took a big ol' gulp of "Pepsi" and promptly did a good imitation of those women.
Rog, I never knew the technical name...
Les,see
Engine - 2oz
Battery - .75oz
BB Fuel tank - .5oz
Radio - 1oz
Pushrods + Covering 1oz
TOTAL 5.25oz
That leaves me 1.75oz for the airframe.

If it's all the same, I'll try not to imagine that!!!!!
Oddly enough, I never smoked although both parents were heavy smokers and I grew up in an area where smoking and growing tobacco were a way of life. My wife has been trying to quit for 12 years -- going for a second acupuncture treatment today. Hang in there -- just keep thinking of all the extra modeling money you'll have to spend.

Hey pt: Don't worry too much about the people you are making mad since you quit. It is probably nothing to it since you use to make me mad when you smoked!

Couple of small changes. Originally, I had wanted to put the servo's between the two 1/8 "spars". Well, the fella that designed this thing was using HS-55's for the measurements and since the builder is using GWS servos, some minor changes will be made. I made a hatch out of 1/16 ply and put that right behind the tank. The servo arms are the only thing that will stick up. Plenty of room in there for the servos to lay on their sides. And the receiver and battery can be accessed by removing the hatch. If you've ever seen a Lil Streak, it's the same thing. The servos attach to the hatch and the hatch attaches to the airframe. Done right, this is very strong.
BTW, the airframe weight is less than the goal of 1.75oz. It's just a tad over 1.5oz.[sm=thumbup.gif] Not real worried about the CG yet, but it may end up being a little nose heavy. The "devil" killer bee has a permanent home now. CP, were you using the 4.2x4 on it, or is there a better option?

The 4.2x4 and 45% nitro is what it likes. I didn't see any pitting on the head or piston, but you have heavy air where you are at, so it's always good to have shims and a tach with you to start out the day right if you are playing with high nitro.

Now, don't laugh too hard, but I forgot the fin when I was weighing it before.[X(] It's gonna be a little over 1.5oz, but still way under the 1.75oz mark! Never did find a copyright on the "combatpigg" fin, so I went ahead and used it. 'Cuz it's cool lookin'. Gotta install the radio and cover tonight. I've got an Open B combat plane to finish up. Gonna try my hand at some combat on the 25th.

Aaron, TD .020? BTW, posted a link to the plans in another thread. Look for the "Delta uploaded" thread.

Looks real SNAPPY DUDE! There's much less wood there than a SWR. It would weigh even less if you went with just an exposed bladder instead of a tank (and it would be a good excuse to get some practice monkeying with a bladderized engine and all the paraphernalia}. That plane should be a real head turner at the field! The highest compliment and proof that your delta is a smashing success, is when you turn around to hand off the radio and all the guys are taking cover under the picnic tables That sucker would look good all black with yellow, orange, red flames, but would probably double the weight of the plane. Keep building them smaller and lighter until something snaps, that's our motto.

Tissue and dope would let you go with that fancy flame option with virtually no weight penalty.
Pt, you need a "beta" tester? I'm feeling the urge to have a go at one of these myself.

Bruce, I've really ***ed around on this. It should take about two hours to be ready for the radio and engine. That includes taping the four sheets together for the plans. I've got some dope(butrate/nitrate), just no tissue. Also, I lack any skill with paint. I do, however, have some parkflier plastic covering that rivals any 'ol CELLOPHANE.
CP, I've already decided to make a second one for my VA. Should be a good platform for it. We'll see!

What are you running for OPEN B? Half of the fun of getting into something new is mingling around and getting a good look at what it takes to be competitive. So many different schools of thought. I think good depth perception is the most important thing to have.

CP, the kit I've got is the Skull Bandit from [link=http://www.screamingeaglerc.net/]screamingeaglerc.net[/link] and a used (and I mean REALLY used) Magnum GP .25. From the advice I've gotten, a .25FX is the most advanced equipment needed. The SB is a pretty unique aircraft in my experience. Here's a picture of the fuselage. I may not be "competitive" yet, but I still plan on bringing home some streamers! (still gotta come up with a cool handle...)

I was going to make an aluminum spike for my black hardhat... Red and white nylon w/ black iron crosses. Sound familiar? If I don't get a streamer, somebody's gonna get beat with my airplane.[>:]
Gotta go to your favorite store.(W**M**T) That's the only place that sells fabric around here. I hope they got ripstop nylon! If not, he sent some purple they had sitting around.

I think that alot of guys would just say to layer on the 2 inch wide packing tape, maybe a little bidirectional tape, and call it good. If you have 5 minute epoxy and spare tape, that will keep you alive out there. The fabric job adds a bunch of weight and the resulting toughness has really turned that category into a high speed demolition derby. what is the span and area of your RC weaponry?

64" span using the eyeball measuring stick. The area is 'bout 480 squares. The tape idea is a good one, but you can't get colored tape around here, much less choose it based on thickness.

I think I saw colored postal tape and caution tape at either a dollar store or a office depot type place. They sell bulk packs and I think you want the thinnest stuff. The thick stuff is too heavy. You dont really need that much color, just some flourescent blasts on the wing tips right over the tape, and brightly colored fins.

Tyvek... do they still make that? I thought housewrap was something else these days. That may be a local problem. That stuff can't be ripped though!
