RE: That nasty AT-6 Bounce
You can tune your struts to the weight of your plane by removing the springs and cutting a few inches off of them. Stock struts are designed for planes up to 50-60 pounds, if your plane weights 33 pounds then those struts are just like pogo sticks. Good luck.

RE: Something that I have to ask
Hi FENDERBEAN To fit in with a bunch of football fans all you need is some enthusiasm and a beer in hand. Model aviators "are" an elite group of people and you need to earn their respect. Showing up at the field with a $10,000 airplane and a cooler full of beer just does not cut it, in fact you may even get run off if you’re consuming alcohol and trying to fly a plane. If you crash your plane into someone’s house and burn it to the ground you may ruin it for every single person whom uses the field. So first you need to learn the rules then earn everyone respect. It’s earned and you have to work for it. You need to crush and burn a few times to fit in. You need to donate some of your time and even some of your money securing the flying site, the guys who fly there have in most cases spent much time securing a place to fly and they are all aware of the issues they face. Nobody what’s some idiot at their field. It sounds to me that your feelings have been hurt and unlike the football crowd, with model aviator you need to earn the respect of your peers. They don’t just give it to you just because you show up with a beer and a plane. Grow UP.

RE: Sailplane Wing Design Round II
Hi Nodd After thinking about your wing I do see a problem. It seems that you’re spacing the ribs too far apart. I think that your doing this to save weight but what you’re doing is remove strength from the wing and adding the weight right back on to the spar. The ribs “do� add strength to the wing by supporting the stress-skin, whether it is plastic iron-on or balsa sheet. The bigger the space between the ribs, the easier the stress-skin between the ribs can be displaced out of shape, in turn collapsing the stress-skin and breaking the wing. Don’t forget about the strength the shin adds to the wing when it is properly supported. I like the carbon tube idea when spacing the ribs far apart. Just saying

RE: Sailplane Wing Design Round II
First I would put the main spar at the thickest part of the rib about 25% to 30% of the way back from the leading edge. Instead of doing all the work wrapping a built-up spar, use a CF tube for the spar. A CF tube about 50% diameter of the average wing rib thickness of the wing panel sounds fine. Just cut round holes in the middle of the ribs 25% back from the leading edge. Slip all the ribs on the tube and glue. Then between the ribs on top and bottom of the CF tube glue balsa filler strips to get the spar to the same thickness as the ribs. Sheet the front part of the wing in the “D� tube configuration over lapping the main spar. The carbon fiber tube wing spar is also use as the wing jointer tube. This type of build up is easy to do, very strong and light, it will also flex under heavy loads without snapping.

RE: Down Elevater to fly level?
Your incidence angles sound right on. But when measuring you should “0� out the tail first, this is how your plane will set in the air at its intended cursing speed. Two degrees of angle of attack on the main wing is “right on� for a nice relaxed cursing speed. It sounds to me you just like to fly faster. Aerobatic aircraft are usually set to 0-0-0, one reason for this is so they can fly upside down with no change in the trim and aerobatic planes more then likely have a more symmetrical airfoils. Before changing the incidence of the main wing you should really check your balance first and maybe change it to see what happens, it maybe a little tail heavy. If it balances out ok then you can adjust the main wing incidence angle to soot your preferred speed range. Remember that you control the plane’s altitude with the throttle “not the elevator�.

RE: Slow CA
On my fillets when using ca I first use balsa sanding dust to build up the fillet then I apply the second coat of ca. This makes a very strong joint and if the parts are not a perfect fit the sanding dust will fill in the gaps. Epoxy has it place and I use it a lot for many different things but icky using it to build the whole plane. Also I would like to ad, some guys use epoxy to glue balsa wing skins to a form core. Wrong wrong wrong, too much weight. Use light coats of “Super 77� spray on contact cement. Super strong, light weight and easy to work with.

RE: constant depth, tapered wing?
Maybe I don’t understand when you say wing tube. But it seems to me this was done this way because the wing tube is of a constant diameter from tip to root and all of the wing rib cords need to slide onto the tube. No other reason.

RE: sorry, can't keep my mouth shut about this
[quote]ORIGINAL: earlwb I don't know. Nowadays it seems no one really  wants to stock parts for engines anymore, be it glow, gas or diesel for that matter. Parts cost money, take up space and they have to pay taxes on them too (think about  the various inventory taxes the states charge). So it is difficult to keep parts on hand and the parts might sit on the shelf for a long time too. Some states charge you a inventory tax when you get the stuff in, and charge you taxes on what you have left at the end of the year too.  I know some small businesses have clearance sales etc around the end of the year and only sell what they have left and won't order anything until the next year too. So you really need to blame our governments for discouraging businesses from stocking up parts.  So then nowadays it is better to leave the parts overseas and only sell what you think you can sell before you have to pay additional taxes on it.  If a overseas business is reputable I have no qualms about buying parts from them. I have done it before and it worked out good for me. [/quote] I agree with earlwb. I just went to the john Deere dealer this Friday to get a part for my 675b skid steer loader manufactured from 1997 to 2005. The part is not available in the USA. The reason why is because any parts that are warehoused in the USA are taxed, so companies will not warehouse parts anymore in this country. I was also told that caterpillar is the same way. The part has to be special order directly from the factory. Fifty percent of our tax dollars each year now go to just paying the interest on the national debt, NO money goes to paying down on the balance of that debt. So our government has even less money to spend to run this country each year. The government is desperate for money and all of us are being held up for this money. We can all expect things to get much worse. There is no problem with buying direct from china, they are good people and are more then happy to serve our needs. “FIRE OUR CURRENT PRESEDENT!� I am.

A huge flock of wild geese had stop for the night [must have been 10,000+ birds in the flock [a gaggle]]. My geese must have been scared of them because they swim up the river away from all the wild geese. I had never seen that many birds in person before and they where right behind my house. I was worried mine had joined up with some wild geese and then few south for the winter. But they didn’t and I doubt if they would, their too spoiled.

Right now though I have a money-pit turbine heli that I’m working [playing] with. The 140 inch version is just “too� much for me at this time. I need more information like total wing area? After running the numbers I would be more surer. I don’t need all the cool goodies and I would have to choose my parts very carefully to fly at 7200 feet. I would want the eclectic version. Do you think that it’s possible to get it to weight about 12 pounds ready to fly, without the batteries? I’m figuring about two pounds for the batteries. It needs to be strong too, my runway is rough.

RE: New CGRCjets super scale A-10
I would like to see you make it “lighter.� I live at 7200 feet above sea level. A RC plane with a 6 foot wing span, a 12 inch wing cord at a weight of 25 lbs has a wing loading of 66 ozs per square foot, “that’s over four pounds per square foot�. I’m afraid to say this but it would need around 80+ mph to get off the ground and 60 mph to land. I build heavy too but I would shoot for 13lbs ready to fly [electric] minus the bombs and rockets and I would pull my hair out trying to keep it under 15lbs. This would slow it down for landing, shorten its take off run and give it much more vertical performance with a wider flight envelope. At fifteen pounds with a 12 inch cord and six foot wing span the wing loading would be 40 ozs per sqft. “Much better.�[8D]

RE: What do I call this part
One of the reasons I would question that the hole is drilled off center is because of how this part is machined, the part is chucked in a cnc machine and the part is turned. The drill bit does not turn, if the piece is not centered with the drill bit the hole would be board out to be wrong size. The part is machined and drilled without ever being removed from the machine. It is just about impossible for the hole not to be in the center.
