Charlie heathco ________________________________ Message 2 _____________________________________ Time: 05:26:16 AM PST US Subject: RE: RV-List: Zulu headsets From: "Chuck Jensen" I bought a Zulu to add to my 30G and two 20s. The clamping pressure is certainly less. Noise attenuation is very good, but then the earlier LS were pretty good already, so the step up isn't a big one. The Zulu has a little cleaner design with higher quality looking plastic than earlier versions. My personal recommendation is I would make it mission dependent. If you fly long flights and don't appreciate the clamping pressure of earlier versions, then the Zulu or Bose is probably worth the money. If you do a lot of local flying and the 30G or 20s are comfortable, I'm not sure I'd spend the money on either the high end Zulu or Bose. The difference in price will buy you a couple tanks of gas...until the next price hike! Aviation Consumer had the Bose and Zulu rated about dead even. Depending on your use, they gave a slight edge to the Zulu because of its Bluetooth capability.

I have never really liked my 3G's -- they are too big and clunky. The Zulu's are very comfortable and efficient. Over the last 12 years, between my wife and I we've had most of the Lightspeed's except for the micro in the ear type. The upgrade is $350 but they won't be shipping for several weeks. I was just about to give up on Lightspeed and buy a Bose set before they came out with the Zulu. My reason for sticking with Lightspeed for so long was their warrantee, service, and plus upgrade policies. good luck dave On Jul 17, 2008, at 4:48 AM, Charles Heathco wrote: > Wondering if anyone has traded up to the zulu, especially if > previously had the 3G's.

I have an O-360 (180HP) in my Pitts. It has the high lift helo cam, 8.7:1 pistons and is balanced. The PS5 carb has been modified by opening up the jets. Supposedly it puts out 200 to 225 HP at 3000 RPM. I rev the crap out of it (3300) when doing akro on 92 octane. If I run regular, it'll ping when it gets hot. I know this doesn't answer your questions, but it's a data point.

I am a graduate of Parks College of Aeronautical Engineering (St. Louis U.). I have recently built an RV-9A, and we have maintained good friendships in the St. Louis and S. Illinois area. We often return to the area. Would Creve Coeur make a good home base, for one or two weeks of visiting, flying and touristing - and does the EAA fraternity at Creve Coeur include some active Parks grads. BTW: I have been to "the Ranch" since graduation - but with the relocation to the main campus, perhaps the concept of the Parks experience no longer exists. Sorry about being off-topic but these kind of memories count, in my book of aviation experience. do not archive ----- Original Message ----- From: David Schaefer To: rv-list@matronics.com Sent: Thursday, July 17, 2008 11:48 AM Subject: Re: RV-List: Trip to St. Louis Creve Coeur has a large EAA following.

I am planning to land at Montgomery County (KGAI) due to its proximity to the DC Metro system. I have landed at Manassas Airport south of Dulles many years ago. I also recently took the FAA online course regarding flying in the Wash DC area, however I would appreciate any hints or suggestions that would facilitate a smooth flight into the area and on Montgomery County Airport. I will probably be stopping at Charleston, WV for fuel prior to entering the Wash DC area. After Washington, I am going to the Gatlinburg, TN area for a few days before returning to Texas. I am planning to land at KGKT (Gatlinburg) but would like some comments from others that have flown into this airport versus going on to McGee Tyson.

I've been to GKT a few times and Knoxville once several years ago (but none were over-nighters). It really depends on what you want to accomplish. If you want to visit Gatlinburg and the national park there isn't any reason why you shouldn't go with GKT. Rental cars are available (last time I was there rentals were via a local Ford dealership) and the service I received was good. If you want to primarily visit Knoxville and don't mind dealing with a larger airport then Knoxville will work. Have a great trip!

Be sure to activate it with FSS before you get too close or Potomac Approach will keep you outside the ADIZ until they can sort it out. Otherwise it's no big deal. I fly out of Manassas (KHEF) which is also in the ADIZ and have found it to be pretty much a non-event. -------- Todd Stovall 728TT (reserved) RV-10 Empacone Read this topic online here: http://forums.matronics.com/viewtopic.php?p=193493#193493 ________________________________ Message 16 ____________________________________ Time: 06:11:58 PM PST US From: "John Huft" Subject: RE: RV-List: 10:1 Compression / IO-360 200 HP The down side is you have to feed it more gas down low. The up side is that it is more efficient up high. A little more power both places. HP gain is probably only a couple percent. It may reduce your TBO if you run it hard a lot. I haven't seen any reliability problems in 500 hours and 5 airventure cup races (wide open for 2 hours at low altitude). Really, it depends on what you are aiming for. If you are after every bit of performance, then it is good. If you just want to bomb around in a great airplane, I would stay with stock. Maybe a better way to go is port and polish. Cheap, and no related problems, just 3-4 extra HP per cylinder. For the ultimate performance of course, you do both. For the very best MPG, add Lightspeed ignition for high altitude cruising.

I know of one of these engines that self destructed in a Mooney, that was being run with only stock instruments, so didn't see the high temps on other cylinders. Others report high oil consumption sometime after 500 hours. Have a friend that is running them with no trouble, but keeps his temps down and stays within the STC requirement on certified planes of no more than 28.5" MP. Other downside is if 100LL ever gets reformulated to lower octane, you will have problems or have to top the engine with lower compression pistons.
