RE: AMA Warning Label on FPV Advertisements???
[quote]ORIGINAL: astrohog Overstepped their rights by SUGGESTING that there are and should be guidelines when flying FPV toys in REAL airspace with REAL lives potentially at stake? I did not see the ''warning'' you are talking about, but if you quoted it verbatim, I see no, ''WARNING'', I see a statement that is made to educate the uneducated, that there may be rules and regulations governing the use of FPV toys. WOW! REALLY?.........Do you WHINE about EVERYTHING? Anybody that has a continuing interest in any sort of r/c flying should support the AMA in their attempts to work with the FCC and FAA where our freedom to fly r/c are concerned. We may not always agree with all of AMA's decisions or directions, but the AMA is our only real hope to lobby for us to continue to enjoy our hobby as we have known it. United we stand, divided we fall. Regards, Astro [/quote] Very well said, AstroHog..! The AMA might someday wish they had totally shunned drone style flight right from the get-go. As time marches forward, model drone related mayhem might overtake the handgun related stories that get reported by the cowardly, politically driven MSM...?

Pylon racers in all classes who are consistantly "in the money" are also experts. 3D flyers who are able to perform their magic [in front of 100s of spectators no less] are experts. Payload competitors...well this event will make fairly competent flyers look like fools, but you're looking at another sort of competition that challenges you to gain expert skills or else bring out the Shop Vac and the Hefty Bags.

RE: Another
Too much angle with not enough thrust puts the plane into a stall if the airspeed after launch isn't sufficient. I'd rather go with a fairly flat launch and if the thrust isn't there, at least the plane is at a shallow enough AoA to take a belly landing into the grass instead of a total stall / snap roll into the dirt. A flat launch gives a small diameter prop a chance to carry the plane at a shallow angle up to flying speed. This is just my approach. If you have ever hand launched one of these planes at 4+ pounds with a 7 inch prop, then you would have witnessed the "miracule of flight" when such a low thrust to weight setup struggles for the first 20-30 feet to get up to enough speed to be controllable. In those first moments I basically let the plane fly itself instead of intervening and screwing things up. For those looking in who have only flown Dusts / Demons with high thrust props, [like 9x7, 9x8, 10x6, etc.] keep using those 45-60 degree launches..this advice doesn't apply to that sort of flying.

RE: Another
I've never had a glow powered Demon RTF less than 3 pounds..so your projected weight will be so easy land at low speed that it will put a smile on your face. can't predict what the launches will be like with the tiny props you want to run, so hopefully your launcher does a good job of that. I wouldn't rig the launcher for very much of an assist and I'd keep the AoA kind of shallow.

RE: Another
Years ago there were a few companies Ansen, Transdapt 9and others I can't remember0 that sold special bellhousings and other parts to make swaps like that pretty simple. I'd love to own an old Willies or an old 1950s Power Wagon with updated running gear. They were known as "Five Quarters" which was slang for 1.25 ton load rating. Now get this, the old 13 ton [GVW] APCs were powered with Chevy 283s that had gear driven 4-71 superchargers..the whole works was painted that ugly OD green..even the plug wires were OD green. I think it would be ridiculously cool to have that exact engine set up in a Power Wagon or Willies Truck. It would need a OD Green bug catcher sticking up through the hood of course. Perfect "Rat Rod" material too, but I'd be afraid of getting struck by lightning for chopping and channeling one of those old relics. It's hard to harbor thoughts like this AND be involved with speed planes too.....so I guess it's high time for me to sit back and watch your speed quest take shape for this summer..!

RE: Another
I think so..the 57 Chevy had those extra 2 bullet things on the hood. It's funny how the car companies copy each other.[.not just inside the corporation I mean]. For whatever reason Pontiac, Buick, Olds had their own versions of the "Tri-5" but they just got too gawdy in the trim department, the Chevys had a cleaner look. Cadillac always stood aloof from the rest of GMC, but they did copy themes. It was popular for customizers and hotrodders to delete hood ornaments and other trim and just junk it. Now that stuff is worth a fortune. Your Electro Demon Deluxe looks ready to rip up some air molecules. Play safe, I think electrics are more dangerous than glow [even though I have seen 2 glow engines start on their own on real hot days...both SuperTigre .35 Combat engines].

RE: HOB ME109.....Plastic Fuse Top Painting
Howdy CafeenMan..it's been a while! It's been a while since I bought paint supplies for models, too. I mean truly fuel proof 2 part stuff like Klass Kote. The cost involved getting all set up is kind of high, but pint sized amounts of paint and hardener will last pretty long if all you are doing is a 1/2A model now and then. I still have K&B epoxy paints that date back 20 years that are still good [even though they need serious stirring]. Harbor Freight has inexpensive air brushes that you can power with the weakest air compressors. The 3M half face respirator works OK for occasional use with adequate ventilation from outside air. I took an old CPAP machine and adapted a 50 foot long garden hose to a 3M respirator it to give me clean fresh, cool air. The machine sits outside well away from the "spray booth" and it supplies all the air you need so very little air actually comes through the filters on the mask. For big projects this helps reduce fatigue because pulling air through cannister filters is work, especially if it isn't 100% clean. I'll bet old CPAP machines are available 2nd hand, or just check with folks who have been on CPAP for several years who might have "out dated" units. I use a 90 degree plastic barbed fitting that runs into a hole I drilled in the mask and the "accordian" style CPAP hose slides over the mask fitting at one end and over the 3/4" garden hose at the other end. I also use a CPAP hose at the machine to connect the machine to the garden hose. The brass ends of the garden hoseare sliced off to make this idea work. It might actually be 5/8" hose...just use the CPAP hose to get an idea for what size garden hose will make a tight slip fit.

RE: Diamond Dust Kit
Yep, I think you've got a good idea there for what it would look like. Take a look at the AMA rules for Q40 design and construction and check out the minimum cross sectional area requirements for the fuselage and then consider how fast those planes are. I was surprised when I first saw those minimum dimensions. No matter how you slice it, the object of the Sidewinder project would be to minimize frontal area and to eliminate the drag that is typical between a conventional fuselage and wing. The exit of the pipe at the rear of the plane would be assymetric drag...but it would be partially blanked out by the thick airfoil ahead of it. I'm surprised that there aren't more examples of this layout in the RC World. It's pretty common in Control line Speed and racing.

I think a Nelson or MB .40 could get a Magnum closer to 200 than Sessholvlaru's 195 mph results with a Nelson Q40 & stock muffler. It would be quite a job to make it all fit in there without making it look like a real "hack job"...but that's why us autistic types enjoy the creative aspects of this hobby.

RE: Picco P-zero 0.8cc
Ooops......I forgot about the rear exhaust issue. It might melt the canopy if it was too close. At any rate, I've never come up with a 1/2A bladder that could hold more than 3/4 ounce and give consistant pressure . What happens if I try to over fill is inconsistant runs and shorter bladder life. If you can rig up crankcase pressure it sure makes life much easier if you want longer, more consistant runs. The weight penalty of a hard tank needs to be considered on some planes VS a simple balsa compartment for your latex bladder. 3/4 oz of 15% nitro is enough fuel to have a nice flight with 5 or 6 [downwind[;)]] passes to look at on the Wavoscope.

RE: Diamond Dust Kit
Yes, a big Sidewinder would be very cool. It would be a total crapshoot to commit to such a fat wing...the wing needs to be at least as thick as the engine is wide at the root. You can get 1/16" or 3/32" balsa to lay down in a compound curve, so the wing could taper in thickness like the modern military designs do. The spars would need to be "arched" against a stout web, to eliminate airfoil thickness as soon as possible moving away from the center section. The web doesn't need to be continuous [full span]...just where the spars need to be pursuaded to merge together after "leaving" the center section of the wing. The whole wing would be designed after the spar design actually got built and evaluated. At the worst it would end up becoming a cool looking conversation piece no matter how fast it goes.

RE: My first Plane
John, how about the "Slow Stick"..? It's technically a SPAD and I've never seen any traditional RC trainer in this size range any easier [or slower] to fly. It doesn't use coroplast for the wing...it looks more like the thin sheet styrofoam that you see at the butcher shop. I don't know how the flimsy wing is made stiffer, probably small diameter carbon or fiberglass tube or round stock. The problem with these planes is they are so easy to fly that they are pretty boring once you have mastered it's control, but for someone who is just learning, [possibly someone with experience on a flight simulator]...the Slow Stick would be a good 1st plane in my opinion.

RE: Diamond Dust Kit
With a rear intake engine you should be able to get away with a smaller diameter crank that is easier to spin [than a front intake type]. Checking the disk valve timing from a known world class rear intake engine like the OPS .60 series ought to get a OS.46DF right up there with the best...especially if Nelson made upgraded parts for this engine. The one comment that Dave Shadel made that sticks with me is that the "modular / bolt together" case design seems less trustworthy than the one piece type. A big obstacle for me would be to learn how to service [or modify] the rear intake valve. A bigger question would be why MB/Profi decided to use front intake when they decided how to build the most powerful .40 in the World.

RE: Diamond Dust Kit
What makes the Nelson .40 capable of 200+ mph is the huge crankshaft that has the huge air passage inside. The FAI version uses a 13mm intake. You can try every "trick" in the world with the "normal" sized crankshafts on other .40 to .50 sized [non racing] engines and never get past the 170-180 mph range on a Diamond Dust. Those engines just do not have the air handling capability of the F3D types. The Nelson .36 combat engine uses the same design principal and it made all other engines in it's class obsolete over night. Years later a few clones were made by other companies. Does the OS.46DF share this feature....? Any .46 that can turn a 9.375 x 8.5 can't possibly be a "high timed" DF engine....? I would expect to hear that it could turn a 7.375 x 8.5 ......fast enough to make some serious power.
