[RCSE] Re: Foam and Vacuum
The foam I use today is exclusively Foamular 250 and Foamular 600. I agree that it makes no sense to use Foamular 150 or the equivalent blue foam (Dow score board) if Foamular 250 or Dow square edge are available. There is almost no difference in weight but a noticeable difference in strength. In all of my high-vacuum bagging experience I have never seen a foam worm. So for me, the mystery remains. Again, I really appreciate the feedback and experience shared. I'll also admit that, based on the comments of a number of folks, the idea of too much vacuum is not very satisfying. I'll still leave the door open to the possibility that it may be something I'm doing in handling the cores either pre or post bagging. However, I've talked with some folks who discount that as well. So perhaps this is something specific to 150 and/or the lots I've been using. Maybe they just don't send the good stuff to Oklahoma? Over the next week or so I'll be checking Foamular 150 (Owens product) vs Dow 250 with vacuum as a variable. The 'Mighty Mini' checks out at 8 in. The ACS pump system has a decent reservoir and pulls down to at least 25 in. In checking my archives from ~ 3 years back, Foamular 250 did not exhibit this problem. I've done about 30 wings in that time and it's only recently this issue came up. As near as I can tell, it just happens with light layups with 150. Sure wish the local supplier hadn't stopped carrying 250. We'll keep looking and will post results. - Dave R RCSE-List facilities provided by Model Airplane News.

[RCSE] LVDS
Asking whether anyone has utilized a Laser/Dopplar velocity scanner (LDVS) on anything inside or outside the hobby/sport. We (local university) will be using this device to measure excursions/displacements across a composite sailplane wing. We will be looking at: - deflection under various loads (at different frequencies/2-3rd order harmonics and displacements), as it relates to rigidity, and lay-up performance - structural rigidity changes between a virgin wing, and one that has controls surfaces, servo access holes etc - control surface flutter versus main wing deflection - anything else we care to dream up Any help would be appreciated from thos familiar with such a LVDS.

RE: [RCSE] Blaster and Other DLG Opinions
Hey All, Just wanted to say thanks for all the info about DLGs. I ended up getting a Blaster. Price and availability are the 2 main factors that decided it for me, but in retrospect it was definitely the right decision. The AUW on mine is 10.5oz thats flying weight, with .75oz in the nose for balance. I used a JR610, 300mAh 1/3AA pack, and the new Dymond D4.7 servos. The servos are pretty impressive! They weigh 4.7grams and have 20oz/in torque! A friend and I took it out on Wednesday and it flew VERY well. Fast, responsive, and it showed even the lightest lift instantly. We didn't fly too long, I had other obligations, and the range check was pretty bad (antenna inside of the carbon boom.) The antenna is now fixed and the plane will receive a new range check and more flight time tomorrow. Other than the range issue it flew great, the plane indicated lift multiple times but b/c of the range issue we decided to keep it close! It even looked decent in sink. I would definitely recommend it to anyone considering a competitive DLG in the future. Anyways, thanks to everyone that replied. Jared -Original Message- From: Jared [EMAIL PROTECTED] To: [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Saturday, October 23, 2004 1:07 PM Subject: [RCSE] Blaster and Other DLG Opinions Hello All, Im looking to get a DLG and wanted some opinions from people that own the Blaster. I would like to get an XP-4, but Im not willing to pay $390 for a bare airframe. But I have heard good things about the Blaster so that seems to be my next option. So, how do you Blaster owners like your Blaster? Any competitive DLG for under or around $350 is within my price range, so if you know of a good one that fits this please chime in! Thanks!

[RCSE] Foam Rating(s)
Following up on compression strength of foam for vac bagging, picked up some Dow Scoreboard in Tulsa, lugged it back to the wilderness, and then panicked when it measured slightly lower bulk density than Owens Foamular 150. However, a check of the Dow website indicates Scoreboard, Square Edge, etc., have a min rating of 25psi. (_http://dowbp-us-residential.buildscape.com/items/?type=products_ (http://dowbp-us-residential.buildscape.com/items/?type=products) ) A small cantilever was set up in the basement and lead shot was added until a 1 square piece of each type of foam deflected 25%. This is a somewhat arbitrary rating but it provides a relative comparison. A very rough calculation back to loading at this deflection gives: White (virgin) beaded foam ~ 16 psi Foamular 150 ~ 21 psi Dow Scoreboard ~ 29 psi It's noteworthy that the white foam remains crushed but the others are gradually springing back. The amount of deflection is continuous with weight so, in effect, the initial modulus of Scoreboard Foamular 150 Virgin beads. Bulk density is not a good rating factor. Not sure what this implies for specific max vac for each material - other than rank ordering them a bit - but if you've got a kid that needs a science fair project this school year .. - Dave R RCSE-List facilities provided by Model Airplane News.

[RCSE] cool visitor at field today
Hi, I was flying today at one of my fields, which is a small airport. Looked over to the horizon and saw this huge glider coming in for a landing. My first thougt was, Skip Millers here! :-) It was a huge t-tail motor glider. It had a 114 hp Rotex motor, mounted in the nose. Had retracts. 77' span. It was a six servo wing, well functions anyway, and spoilers. Cruising speed was 135 knots. Cost, well I was telling my girlfriend about it and asked her what she thought it cost, and she guessed $10,000. I said I had that much in molded planes and gear in my van, only because one was a Icon. :-) (just joking Don) Cost of motor glider, 1/4 of a million. Made my hobby seem real cheap. Going to order another Icon. Dave Hauch Mich. RCSE-List facilities provided by Model Airplane News.

[RCSE] WAY cool visitor at field today
Dave, What you saw was a Stemme S-10 motorglider, pretty much top dog on the motorglider food chain, and just a ridiculously impressive aircraft. Not only 75'plus span, but comfortable side by side seating for two adults, fully retractable landing gear (in a tailwheel configuration) close to a 50:1 glide ratio, min sink of 112ft/min, stalls at 48mph, 700nautical mile cruise range, with powered service ceiling at 30,000 ft, revolutionary centripetal propeller deployment from a telescoping nose cone. The engine actually sits behind the occupants and drives the propeller by a torque shaft extension that runs between the two front seats to the nose cone. Single lever transition from glide to powered flight in 5 seconds. Wings are foldable by one person to normal hangar span. All ground operations can be performed with wings folded. Read the brochure at: http://www.stemmewest.com/pages/S10_E.pdf Unlike almost any other motorglider in its performance class, the S-10 is perfectly fine to use as a cruise aircraft,(in most the motor is reserved for launch-only operations) It has 139 mph turbocharged cruise speed burns maybe 5.2gal. per hr., which works out to about 27 miles per gallon. Cockpit has complete instrumentation. I'll stop before I start drooling on the keyboard here. Oh, wait, did I mention the solar panels that provide 30W of electrical power for onboard equipment when the engine is off?

Re: [RCSE] WAY cool visitor at field today
Thanks Scobie for all the info. He took off and circle around the field only a couple hundred feet up and came back around for a fly-by about 50 feet off the ground, this baby was hauling butt! I couldn't believe how fast it was going in such a short time, almost clipped a light pole when he banked it around like a crop duster. Sure was alot of wing there.
