RE: National 747 crash
[quote]ORIGINAL: willig10 You would be correct if this was a pure jet. The engine is a split spool engine and the 3rd stage wheel drives the compressor. The compressors 1st stage is the fan. It is the fan that provides around 90% of the thrust. The other 10% come out of the exhaust cone. Another way of determining a high bypass engine is in it,s thrust reversing system. A pure jet will have clam shell doors that are mounted on the aft end of the engine and when activated they cover the exhaust and divert the exhaust/thrust forward. On a high bypass engine the thrust reversed is mounted on the aft end of the inlet. This is called a cascade reversed and it diverts the fans thrust forward. This is because,smoke? the majority of the thrust is in the 1st stage fan/compressor. Glenn Williams [/quote] Huuhhh!!!! So the thrust reverser system determines whether it's a high or low bypass engine................. Uh, never mind, not worth it.

RE: National 747 crash
[quote]ORIGINAL: willig10 Also forgot to mention. Someone mentioned smoke from the engines during take-off. The 747 uses high bypass engines which are split spool and only 10 to 15 % of the thrust comes from the engine itself (out of the tailcone) the majority of the thrust comes from the compressor usually about 90%. These engines are more fuel efficient, quieter and cleaner burning than a "pure jet" engine. Regards Glenn Williams [/quote] Huuuhhh! Would that be the LPC or the HPC? Basically, on low or high bypass fans: 1) Air enters the core via the fan which is driven by the LPT 2) Majority of it is accelerated out the back (thrust) 3) A portion enters the core and is routed to the LPT and the HPT compressors 4) It's compressed, mixed with fuel, ignited, becomes energy (heated air) 5) The heated energy and pressure energy result in rapidly expanding air passing thru the turbines (turbins), they spin the high and low pressure turbines, and they spin the fan (and the compressors) 6) Air exits the turbines (thrust) and the engine through the exhaust nozzle (a little more thrust) It's an old process, they suck, squeeze, bang, an blow, so do recips. Just adding 2 1/2 cents. As a former freight dog, load shift ain't fun hk

RE: Futaba FP-8SSAP Single Stick Transmitter 2.4GHz Conversion- Success!!
But what a really clean, novel idea. Wonder why the experts didn't think of it (or didn't want too). In essence, the PCM is decoded by the DIY encoder and then transmitted via a PPM signal to the DM8 module and then transmitted at 2.4 from there, is that correct Ohnas. And the signal looks very clean too. Brilliant! A Guiness anyone? Mark

RE: Bootlegger?
[quote]ORIGINAL: cmgtech1 I flew a Bootlegger in the early 80's. Flat horizontal stabilizer. Absolutely loved that airplane! I'm pretty sure the wing was a thinner airfoil than the Compensator, and the Compensator was thinner than the Deception. There is an obvious difference in wing planforms between the Compensator and the Bootlegger. The Compensator was a double taper planform, whereas the Bootlegger only swept the leading edge. I flew an OS.61 rear exhaust and rhom-air retracts. The plane had an amazing flight envelope. It would blister across the sky, yet settle right down for slow speed flight. Spin entries were a piece of cake as the Bootlegger transitioned very smoothly from level flight to a relatively high alpha without wanting to balloon a lot. At the end of practice flights, I loved making a low high speed pass downwind, and then follow up with a low, inverted, very slow pass coming back upwind. I was always amazed that an airplane could be perfectly at home at such opposite ends of the speed envelope. For whatever reasons, the Bootlegger just never gained the following of it's contemporary brethren. It wasn't on the scene long before the dreaded "turn around" started dictating major changes in pattern aircraft. A great model! [/quote] For a second there I was flying my tuned pipe Rossi (side exhaust), with B&D retracts, at the ole Radio Control Club of Chicago (RC3) field down at Kickapoo Woods in Harvey, IL back in the day! Nice description cmg, sure do need to get one and get it going again. Yes, a "great model" indeed! Mark

[quote]ORIGINAL: Silent-AV8R Given the short notice on most VIP TFRs is there enough time to get a waiver? Rich Hanson from the AMA has spoken with the folks at the FAA that do the TFRs and they never indicated that a waiver was possible. In fact, they were less than cooperative to say the least. They basically blew the AMA off with a sort of a "you're joking, you are talking about model airplanes" attitude. Rich has made repeated attempts to open a dialogue with the FAA about this situation with no real success.

[quote]ORIGINAL: Silent-AV8R Under Bush the folks around Crawford, TX were afected. Oh wait, there isn't anyone around there [&:] Under Mitt the folks in San Diego will be hosed when he goes to his La Jolla mansion. And they can fly all year, so being closed down for Christmas would not be any fun. Point is, again, all Presidents travel and for now the FAA is going to continue with their draconian policy of closing down as much flying of any type that they can. This has nothing to do with WHO is President. All that changes with the who is the where. [/quote] Likely I'll regret putting my 2 cents in... I mentioned this quite awhile back as I saw this as a potential issue with contests not in the Chicago area but elsewhere as well. In short, the rule by which presidential TFRs are issued (14 CFR 91.141) is a waiveable rule under the waiver provisions of 14 CFR 91.905. The waiver can be issued as long as the operation can be safely conducted under the terms of that waiver. I think everyone can agree that it can be accomplished safely since we are all on that page. Whether the FAA or any of its LOBs are Draconian or not matters little. What matters is folks being able to attend contests that are set well in advance of the majority of TFRs and have a number of economic implications if a TFR results in a cancelled event. It might not be an easy task initially, but once done and modellers demonstrate that it can be done, it is likely easily repeated. Since I plan on attending a few pattern contests this season, that's just my two cents worth on seeking a longer term solution to something that isn't going away anytime soon. hook

A few creases in the outer box had me concerned but upon inspection there was no damage. I'm pretty impressed with the GPMA DB overall. The paint looks great on the fuse, the covering has a few wrinkles, mostly on the bottom (no biggie). My only gripe is the ailerons on both wing halves are warped, enough to easily measure and cause trim problems. This is one area where I'd rather install the control surfaces myself instead of them being pre-hinged. I know there are ways to work the warps out, it's just a pain for me (so any ideas or methods you guys have post em here!). The rudder and elevators are near perfect; the stab tips T.E.'s are angled slightly but shouldn't be a factor. The canopy area is a bit on the thin side (a tad flexy) so I'll ad some thin epoxy and carbon tow there I think. Other than that, I think I'd have to give the DB a solid 8.5 in terms of my overall satisfaction with the quality etc. (with ARFs, a 9 is probably a 10). For grins I'll compare it to the wood kit this weekend at my other build shop. I don't see any issue with mounting the engine vertically and will likely use a side exhaust Rossi/pipe set-up. I'm looking at using a 12 oz shampoo bottle for a tank; I may try a 14 oz but 12 oz has seem plenty thus far. Probably won't start on this until after mid summer though. Keep the info coming. Mark
