I can picture how you'll fill your passengers with confidence when you tell them, "There's a part back there that'll kill us if it cracks, so I have those little windows so I can look at it once in awhile. Almost every plane I flew in Alaska has these inspection windows in key locations, because as a matter of fact there is a part back there that will kill you if its lose or cracked or what have you. Next time you climb aboard a Twin Otter take a trip to the tail section and you will be surprised at what you find, yes there should be a plexi-glass window over the elevator control horn bolt! Almost every PA-18 that gets overhauled by anyone who knows what they are doing will have the aluminum inspection panels replace with plexi-glass units. They are not needed on planes like the C-150 because you can move the elevator up and down to inspect the horn, bolt, nut and cotter pins. Remember most true passengers are just ignorant warm bodies who occupy your seats, decrease your performance, and ask stupid questions so who cares what they think. (sorry a little commuter airline pilot attitude showing here) Depending on where they are from they might be concerned why you don't have the little windows! :-) _______________________ ~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Just Plane Nutts mailto:mimsmand@ix.netcom.com http://www.netcom.com/~mimsmand ------------------------------ Date: Tue, 13 May 1997 22:16:12 -0700 From: R Covington Subject: Re: KR: Re: Elevator control inspection windows?! >>>I made both a top and bottom elevator bellcrank inspection area on >>>my KR-2.

A regular inspection plate might be easier, but it _would_ be handy to be able to just look right through and check things. That's why I will have a clear cowl.

We are also fortunate enough to learn from the Dragonfly guys who have already hashed this out for us. They found the exact same thing over the past 3 or 4 years. You will fly fast and you will fly high! A PRSU isn't the answer to everyones powerplant needs. Now after saying all that, I have been doing a little research on some of the belt drives that have come and gone over the past years, and of course, studying ones that are still here too. I have copies of some of Blantons old belt drives and there is a lot of information that would enable the true homebuilder to build his own. Materials used in the construction of the "box" are 3/8 2024T3 aluminum plate, bearing housings are machined of 6061T4, the aluminum channel that is bolted between the plates is referred to as "standard commercial U channel", the prop shaft is made from 2 inch 4130 steel with .250 wall thickness, it is heat treated to 130,000 PSI, (how do we do this?) bearings listed for use on the prop shaft are: MRC 310-SZZ for front bearing on prop shaft MRC 210-SZZ for rear bearing on prop shaft Alternates are listed as: SKF 63102RSJ " " SKF 62102RSJ " " Belts used back then were Goodyear 12COS8m:224 it is an 8mm Cogg belt that is 4.724 inches wide (8mm being the pitch) I think the Gates Poly Chain is probably a better setup, after all its about 10 years newer. Just though I would share this info, who knows maybe someone out there is looking and may need it. Now you ask why am I looking at PRSUs? Well after attending the Chino Aerofair and talking to the guy from Belted Air Power I almost saw the light, and no not the light that is passing through one of my ears to get to the other! Well I am considering the 2.0 liter VW inline four banger that has been around forever (was 1.8 liter in the 80s). This engine is very plentiful here in Southern California so availability is one reason but there are more. 1) Makes more power than a Soob (Im talking in the car before you touch it) 120 hp 2) Weighs slightly less than a Soob (long block is 148 pounds) with redrive ready to run, 220 lbs 3) Aftermarket hotrod parts are available (no secret cam grinds like on the Soobs) for less than equivalent type four parts, tuned pipes, tuned intakes, ported and polished heads, cams, weber side draft carbs, Holley carbs, forged big bore pistons, forged cranks, MSD ignitions, the list goes on 4) Turbo and Supercharger kits are available if you want 5) A naturally aspirated 2.0 can easily make 140 hp @ 5500 RPM 6) Complete rebuilt 115 hp 1.8 liter engines are available for less than $1500 just down the street (15 miles) The one and only disadvantage is that it is 23 inches tall, some rework in the oil pan or maybe a dry sump with oil tank may be in order to fit a KR2S. Or a cowling mod, take a look at my home page, I drew a cowling that would accommodate the engine. I don't know how many of you are familiar with this engine but it has the same reputation as the Soob as far as being one tuff little unit. Ok who is the whiz at redrives? If an engine is making 120 shaft hp at the crank, what happens after it is run through a belted drive with a ratio of 1.75 to 1? I would guess you would loss a little HP to the drive but gain a little torque? Please help me you engineering types! PS If the VW water burner doesn't work out there is the all aluminum Saturn engine of 130hp that is lighter! _______________________ ~~~~~~~~~~~~~~~~~~~~~~ Micheal Mims Just Plane Nutts mailto:mimsmand@ix.netcom.com http://www.netcom.com/~mimsmand ------------------------------ Date: Wed, 14 May 1997 02:21:17 -0700 From: Donald Reid Subject: Re: KR: Re: Elevator control inspection windows?!

There is also a PCPac version of these the GA30, and GA35, on the 8 satelite version the MAX speed was only 90 Knots on the GA31, but the GA30's max speed was 999 Knots. I would get clarification before buying as one of these could be a typo, a unit limited to 90 Knots would not be able to keep track of position if you cruised faster than that, or might be flaky around 80 knots who in a boat would care?... The cheaper $150 GPS unit from Navtech will only work with one type of mapping software, so you couldn't use a scanned nav chart.

Be careful to be below the bottom of the longeron by a bit. 2) From scrape 2.5 mm birch, I used a 2 1/2" hole saw and kept the disk that was cut out. 3) Using the disk from step 2, I used a 1 1/2" hole saw and made the disk into a doughnut. 4) Glue the 2.5 mm thick doughnut inside the fuselage, centered over the hole cut in step 1. This gives a reinforcement flange with a uniform 1/8" (approx) surface inside the first hole. 5) After final paint, get a small piece of 1/16" plexiglass, and cut a disk to fit in the hole. "Glue" it in place with a bead of white RTV or bathtub sealant. The inspection ports on the top surface will be made from the 1/16" plexiglass, heat formed (using a heat gun) to the same curvature as the fillet surface. I plan on sealing it in place the same way, using the white RTV. - -- Don Reid donreid@erols.com ------------------------------ Date: Thu, 15 May 1997 12:56:07 +0000 From: Robert Lasecki Subject: KR: inspection covers I have been concerned since starting to build as to where to place inspection covers. Last night I went through the entire set of wonderful plans and instructions which were not included in the price of my "complete" KR-2S kit. Nowhere in the documents does it say anything about providing for any inspection access. I like the idea of clear covers as it makes inspections easier and allows each preflight to be more thorough. Any further comments on inspection plates would be quite welcomed. ------------------------------ Date: Thu, 15 May 1997 11:53:43 -0400 (EDT) From: LVav8r@aol.com Subject: KR: KR-2S side panel question In my ethusiastic haste to glue my first side panel together I neglected to remember not to glue in the vertical at position N. Is this a serious screwup requiring cutting that member out or can I just leave it in and not glue the other sides vertical in?

The problem is that the forward and aft facing edges of those members need to be perpendicular to the fuselage centerline, but now they're probably about 10 degrees off. Also, you definitely want them to be parallel to the horizontal stab spar, which isn't there yet, and may not be perfectly vertical. It'll probably be close though, so I'd shim the aft face, and sand the forward face of those members when the time comes (to make your plywood webs exactly 5/8 inches apart, and with full glue contact), and add an additional member which has the proper taper to the other side each of the plywood members. Then your bulkheads will be even better secured than stock (and slightly heavier). Basically, don't worry about it till bulkhead time, but if you've only done it to one side, don't do it to the other. There may be a discussion of this in the archives, I think, although that may have been before Carlos started the archives.

Then sand flush.

It turns out it was a PAIN to install the members after the fuselage was assembled and it's time to mount the Horz Stab. The only downside may be that you might have wanted some flexibility to move the Horz stab spar fore-aft. If memory serves these verticals capture the plywood webbing for the horiz stab. Having one fixed means that you would only need to cut it out if you wanted to move the horiz stab fore or aft. This could be done by planeing the surface and/or adding plywood shims to the member installed. (Thats my take on it.) -- Ross LVav8r@aol.com wrote: > > In my ethusiastic haste to glue my first side panel together I neglected > to remember not to glue in the vertical at position N.

You need a stable computer platform and the only thing remotly resembling that from Microsoft is NT. I am waiting for some of the real time threaded Java operating systems to mature. I can't imagine Bill Gates flying in anything that depended on one of his operating systems ;-) If anyone is interrested in any of the discussions on aero computers the original thread is archived on my home page http://www.evansville.net/~newtech. Still waiting for Intel based operating systems to demonstrate their robustness.
