I have mounted one wing at a time to get it final drilled, but just barely enough room.

I have a question for the wrenchheads on the List. I am considering Bart's XP-360 with a slight modification. I would like to have it made with lower compression jugs to permit the option of using auto fuel if the need arises. Aero Sport says that this is not a problem and that the final compression ratio would be around 7.5:1 for an estimated output of 170 hp in the carbureted version. Aero Sport indicates that 80 /87 Octane would be appropriate. I am planning on using a Whirlwind 150 series C.S. prop with this engine. Now for the questions: 1) Is this a stupid thing to do? All opinions are welcome. 2) Any issues with lower compression jugs and prop harmonics. or are the harmonics a function of higher compression levels? 3) Does auto fuel damage any component of the fuel system? 4) Do the valves need a steady diet of lead in the fuel for any reason, and if so, would an occasional run with 100LL keep things happy? 5) AeroSport's suggestion of 80/87 octane has confused me. Does this mean that I could run 89 or 91 octane auto fuel, or is the 80/87 some sort of avgas that I have not run across yet? 6) Anything else to consider? I am building a RV-8 (Yes, I have decided to go with the taildragger since obtaining my tailwheel endorsement last month.) and think that 170 hp should be enough to keep up with the local spam canners. My ship is going to be one of the lightest out there due to a secret modification that I am undertaking. Since you all are going to be generous enough to give me lots of help with my engine questions, I am going to share my revolutionary "lightness" design with the List. I ask that you not leak this design to the media or to anyone outside of the RV community. Here it is: I have constructed air bladders inside every bay of my wings and tail. I will do the same for my fuselage. Each of these bladders will be filled with Helium. (Hydrogen is cheaper, but that Hindenberg thing sort of tilted the balance in favor of Helium.) Each of these bladders will be fitted with a bleed-off valve in order to keep the bladders from exploding as the atmospheric pressure drops at altitude per the latest thread on the List about carrying liquids with air space in the containers. I will also fill my tires with Helium for additional weight savings. My calculations indicate that I will need a person holding down each wing as I taxi to keep her from leaping into the air. Seriously, though...my secret to a light airplane is that my genetic makeup has kept my "gross" weight at 145 lbs. (That's 11 Kilometers to our metric brothers and sisters) At 145 lbs, I will probably need wing walkers to keep her down while I taxi!!!

The event will be held at the Nashua, NH airport (ASH), and activities will start at 10 AM. This year program organizers have decided to focus on key areas that influence the completion and safe operation these extraordinary airplanes. Presentations will include the introduction of new and very cost effective autopilot system designed by one of our members, a discussion of acrobatic flight maneuvers, a briefing on the issues leading to the award of the airworthy certificate and the proper preparation for the first flight and performance evaluation. A Wings program, Spatial Disorientation, is also being offered and will include the opportunity for pilots to test their own tolerance in the spinning chair. A cook out is scheduled at noon and everyone will have the opportunity to check out a variety of completed RVs and check out a few under construction. Arriving aircraft will receive specific taxi and parking instructions on ADIZ. If the weather doesn't cooperate, the alternate date is June 28th. RV pilots and builders within the region and encouraged to spread the word and their wings to help us make this event a success. ________________________________ Message 6 _____________________________________ Time: 05:51:11 AM PST US From: "Dean Pichon" Subject: RV-List: Engine accessories for sale --> RV-List message posted by: "Dean Pichon" The following components were purchased new for my -4, but were never used.

Luxury would be a hangar or at least a workarea big enough to hold the assembled aircraft with 3' all around. However, as others have already mentioned, many RVs are being built in single-car garages or less. I built my tail and wings in an apartment living room by having the painting done for me and moving outside for some operations like prosealing the tanks and riveting the spars. This required planning to work around the weather in Michigan. There was not enough room to build the fuselage there, so I had to wait until I had a garage. Now I am constructing the fuselage in one half of a two car garage. When the time comes to mate the wings, I will either do one wing at a time by moving the car from the other side and moving the fuselage around or I will plan it so that it occurs during good weather and mate the wings in the driveway. Once the wings are fitted, they come back off and need not be fitted again until assembly at the airport. See Dan Checkoway's website for this, or the Orndorff videos, where George and Becki roll their wingless fuselage into the back yard, plumb plastic tanks to the fuel system, and fire up the engine. Bottom line, a two-car garage of any dimension will work for an RV.

I've read the standard reference to a '2 car garage' but this is too vague. I have a newer condo with a two car garage but it only measures about 20'x19'. Is this enough square footage? The garage has two separate 'doors' with about a 4 foot 'wall' between them so I know final assembly in the garage is out of the question.

Since most of my incoming mail is RV-related, I'm posting this warning so that people will check out their own systems. The virus in question creates bogus messages in my email client's (Netscape) inbox, with blank subject fields and no contents. If those messages aren't deleted before viewing a real message, then the rest of the real messages in the inbox will be corrupted or deleted. I've tried McAfee & Symantec anti-virus utilities with zero success and I'm starting to get frustrated with this. If anyone has any idea what this virus might be and can propose a viable solution, I'd be very grateful. You'd think people would have better things to do than to cause random mayhem for strangers.

All opinions are welcome. >>A friend of mine did just that for his Bearhawk. He had an O-360 engine built with low compression pistons so he can burn Auto-Gas, however he also used the Angle Valve Cylinders of an IO-360 in his mix of parts.

Do your research on every component that goes into your aircraft for compatibility, though. 4) Do the valves need a steady diet of lead in the fuel for any reason, and if so, would an occasional run with 100LL keep things happy? >>Run every forth tank or so on 100LL to resupply lead to the valves (or run a 25%-75% mix) For more deatailed Auto Gas info, see these websites: WWW.AUTOFUELSTC.COM or WWW.EAA.ORG 5) AeroSport's suggestion of 80/87 octane has confused me. Does this mean that I could run 89 or 91 octane auto fuel, or is the 80/87 some sort of avgas that I have not run across yet? >>Next time you fill up your car look at the sticker on the pump for an explanation on how Octane is expained/measured (RON+MON : 2) 6) Anything else to consider? >>A dedicated Saving Account for all the Money saved!

I believe the engine is probably putting out more like 160 h.p. If the engine has sat for awhile, it probably is okay if he kept the oil in it. However to give you my personal take on it. You are going to be the one flying behind that powerplant. An 0320 is a good engine (as long as it has two independant mags. I would after purchase dissassemble and send the case halves, sump and accessory case to Divco in Tulsa, have them line bore & size the cases. send the crank and cam and connecting rods also and have them NDT'd and magna fluxed. replace all bearings and purchase a cam outright brand new. Put everything back together and you will have the knowledge and comfort of knowing that the engine is sound.

It helps to lubricate the valve guides and keep the valves from sticking. It is added at the fuel farm when they brew the fuel. If you are going to use unleaded gasoline it is recommended that you use a top end lubricant in the fuel to aid in lubricating the valve train. Most people I know use Marvel mystery oil or an additive that is available at FBO's that they place in their unleaded fuel, prior to pumping it in your plane.

I looked at that one about 5 years ago and got really interested in it. Talked to the designer a bit and it appears it's a real design having originated within his Master's program. He told me they had a few things yet to work out and they expected to license it for production or maybe limit production to in house. Said heating had been a problem they were working on still -- don't remember what else. I can't think of a good reason this would not be a very valid AC engine given a proper shakedown before production. At the time I talked to them he was estimating about $25K, which seemed to me to not be a good strategic price to attract the pioneers he would need to get it kicked off right. Don't know if he ever made it into any real production or not but assumed he probably did. As for propellers, it should handle very large props, multiple blades and heavy pitch very well. This engine has massive torque and really, really likes to operate around 12-1500 rpm and is just pickled tink to idle around 150 or so. For some newer technology and a much better history of reliability and cost/performance, I'd be much happier with modern rotary engines myself. In fact, that's very likely what I'll use. JMHO...

That means more blades, diameter, chord, airfoil or other design change. A CS prop optimized for cruise at 2450 would probably suffer at 2000 rpm trying to absorb the same horsepower. Just for reference, my Navion's GO-480 prop is turning 1764 rpm at my cruise engine rpm of 2750. It's turning a 93 inch 3-blade prop with 295hp.

It's 01:01 then! So it's John Deakin's vs. Peterson Aviation's statements. Did you actually read the material on what I supplied you links for? Do you think Peterson Aviation did their homework and therefore "sound very credible" to you also (P.A. claims to have sold over 30,000 STC's based on their actual research on AutoFuel)? No offense man, but you know what you know, and whatever you know is just FINE with me. Can you explain to me the following Statement made by John Deakin in his report under *Lead Myths* (I did read a quick few parts of it): " . . . I do have one report that high-output marine engines had some valve problems when switched from mogas to unleaded fuels, but that same report said that hardened valve seats took care of that problem. . ." That sounds like increased wear after dropping the lead that does not lubricate, right?

Automotive fuels are not rated in this way but use an antiknock index and an average of the research octane method, and motor method. The antiknock index posted on autogas pumps is approximately five points higher than the actual octane rating of aviation fuelthus an an-tiknock index of 87 posted on an autogas pump would equate to about an average 82-octane aviation fuel. Autogas STCs for 80-octane aviation engines require a minimum of 87- antiknock index. http://www.eaa.org/education/fuel/autogas_vs_avgas.pdf Larry in Indiana, RV7 Tip-up O-360 3XG reserved.
