    Subject: Engine Delivery Question
    From: "nukeflyboy" <flymoore@charter.net>
    I decided to order the Van's deal on the Lycoming engine and got in before the price increase. Delivery is scheduled for some time next week. For those of you that received an engine from Lyc via Van's, what do I need to do to prepare? Will I be expected to remove it from the truck or will they have a lift or some means to get it to ground level?

    Hey Dave, We didn't get our engine from Van's, but I imagine they'll all be about the same. Ours came bolted to a pallet using two temporary mounts for the two lower rear mount ears and a third brace that supported the front hub -- it works quite well. The delivery truck had a hydraulic tail gate and the driver had a manual pallet jack he used to roll it into the shop. I took the sides and top off the crating, used an engine jack to raise the engine and pallet together and screwed swivel wheels from harbor freight onto the four corners -- as long as you're on a hard floor, it roles very easily. With an engine leveler gizmo attached to the engine hoist so that the angle is the same every time it is picked up, it is no trouble at all to mount and dismount the engine to the plane and back to the pallet during the cowling fitting, hose/cable fitting, etc. Later, - Lew -------- non-pilot crazy about building NOW OFICIALLY BUILDER #40549 Painting done!

    Subject: Winglts ?
    From: "Lew Gallagher" <lewgall@charter.net>
    Hey guys, I've been thinking about this for awhile and thought I'd air it out -- especially now that many of you might check it out at Osh with the vendors. What do you think of winglets instead of just wingtips? Supposedly they create a better vortex, enhance lift ... ? I dunno, but now I see them in the magazines (Plane & Pilot) on the new Diamonds and Cessna 400 etc. -- not just the big commercial planes. >From a builder's point of view, is it just as easy to fit a winglet as a wingtip?, stress/structure issues?, would they change flying/handling? how to engineer them for the -10? I read here about counting ounces and fine tuning everything from injectors to positioning antennas to tweak the most out of efficiency, reducing drag, etc. ... winglets would seem to be an obvious area to look into. Whatcha think? Later, - Lew -------- non-pilot crazy about building NOW OFICIALLY BUILDER #40549 Painting done! On with wiring and avionics.

    Subject: Re: Engine Delivery Question
    I did the same thing. As I recall, the delivery as either 'free'or involved no additional charges. The trucker called and I explained that we could take it at the driveway. For the delivery, I was prepared to have my neighbor help with his tractor. The truck came, used his lift ramp to put it on the ground, and used a hand fork lift to roll it onto the gravel drive. Later, my neighbor came over, we strapped it on his shovel and put it in the hangar/shop. No problems. A week later, I rec'd a letter in the mail from the trucking company for a $90 lift gate charge. It took a few calls and a fax of the charge back (to Lycoming I recall) for the charge to be voided. That was my experience. BTW, when the time came, I was able to unpack and otherwise move the engine around and mount it using the HF engine hoist and balancer. A good deal. Note that the engine is sealed in heavy plastic along with some large dry packs. As I recall, the dry packs are visible from outside the plastic. And they have an indicator telling you whether they are still functioning (they can be renewed in an oven). So you can leave the engine packed with some assurance that it will remain dry. nukeflyboy wrote: > > I decided to order the Van's deal on the Lycoming engine and got in before the price increase.

    When mine came the truck had a hydraulic tail gate, which was paid extra for. I have a fork lift (ancient and decrepit, but it runs) and I used that. Since I didn't use the tailgate ..... the charge was refunded ..... probably to Lycoming :-( . Depending on whether you have to go over grass or not, I'd build a dolly with good casters on it that will handle a 4 X 4 pallet so you can get it from the spot in your driveway to your shop. I have all my parts stored in a room in my shop, and the engine wouldn't fit through the door, so I uncrated it and put it on a dolly .... and tyhen it just fit. In hindsight, I'd probqbly just push it into a corner and leave it alone. Linn nukeflyboy wrote: > > I decided to order the Van's deal on the Lycoming engine and got in before the price increase.

    Ditto on this post. I have a friend who replaced the entire fuel line system in his L19. Then he found out about his crappy flare tool and got to redo the whole system again. Couple days down the drain. A drop or two of oil on the tool also helps. Also, make sure you have filed and taken all the burrs off the end of the tube before you flare. The burrs and chinks are the nidus to start a crack in the flare. I used some fine scotch brite to polish the ends before flaring. Rise out the tubing to get rid of any bugs/chips etc before final installation. Dr Fred.

    From: Dave Saylor <dave.saylor.aircrafters@gmail.com>
    There was a great discussion of winglets on the Lancair Mail List a few weeks ago. What I took from it was that winglets improve efficiency at high angles of attack: take-off, climb, landing, and very high altitude cruise. Perfect for airliners and pressurized GA planes but not so helpful for planes like RVs. At low angles of attack, where RVs excel, winglets would most likely slow the plane down. Plus, there's a lot of engineering and testing that goes into a winglet--they aren't a simple bolt-on. The angles and airfoils are critical. I understand the airlines use them to gain tiny efficiencies that pay off over millions of miles.

    A neighbor of mine hosted a rotary engine fly-in a couple months ago. There was a guy there that has a custom fiberglass molding business - he brought a pair of what are called "finch-tips". These are tips where the outboard edge sweeps down and rearward. They only fit the 4/6/7/9 currently and he was looking for someone to test fly them to gather numbers. I did the work to install them on my 7a and have flown them twice so far. The stall speeds are unchanged, but in my trials so far, I've seen that the mid-power range speeds are improved by about 7mph. I'm far from complete with my flight testing, but they are showing promise. I have photo's posted on my picasa page - http://picasaweb.google.com/n520tx/NewWingtips#. When I get all my testing done, I plan to post up the final numbers on my web site. For what it's worth ...

    You may have to pay extra for the lift gate, but worth it. I tipped mine onto a Harbor Freight (1000# capacity) furniture dolly which has two advantages. One - you can move it around easily, and two - you can get the forks of the engine lift under it when it is time to mount it, -------- OSH '09 or Bust (busted) be there someday Q/B Kit - end game Read this topic online here: http://forums.matronics.com/viewtopic.php?p=253347#253347

    Ron, Thanks for the post. The tip looked like a pretty good match for a prototype. It's funny how ego plays a part in these things. The exact same wing tip flipped up has some marketing potential but a turned down winglet much like the old Cherokee wing tips are more of an eyesore (to my design sensibilities). Regardless please keep us informed of your test results.

    I had identical issue with my Glastar. Cleaned out RTV and spaced the baffle with one washer. Dropped the CHT over 30 degrees on #3 cyl. Will soon see if RV 10 has temp issues.

    That, and the fact that the wing is 'Hershey bar' shape. I think winglets would be far more efficient on a swept wing.

    Well, I kinda like the droop tips on the Cherokee. Klingon warship comes to mind. I think the droop style would help the low speed stall far more than a swept up winglet. The droop tips on the Cherokee really do make a short field landing far shorter!!! Linn Robin Marks wrote: > > Ron, > Thanks for the post. The tip looked like a pretty good match for > a prototype.

    The larger mass of an upgraded rotor can assist cooling as can a larger caliper. The technical support at Cleveland can assist in beginning with their parts used and larger upgrades. Tim James did a great job with OEM Cessna. There is also Beringer. Beyond the benefit of cooler temperatures is the shorter stopping distance at the same speed and same weight. Don't forget to think about a fluid upgrade as H-5606 is more combustible than alternatives. Once a brake line leaks the chain reaction begins.

    VGs also help the slow speed characteristics without shocking the design sensibilities of a few readers. What one calls a winglet might not reach the NACA standard, but might be just another unique wing tip design. New ideas are always a fresh perspective with OSH just around the corner.

    Robert, I am going with 0.375" thick rotors and dual pad calipers per side to spread the force. A couple of RV-x main landing gear caliper fires that consumed the glass pant caused a few to change from H-5606 a few years back. The flame propagation was right below each main AVGAS fuel tank. Fiberglass fires are a perverted thing to watch. So take a test sample and learn by experiment not experience how the cured resin and glass strands come to life until gone. Mine was watching a '69 Vette being prepped for custom paint. VANS mantra is stay conservative with the brakes and build your kit bone stock. Some of us tend to lean into the wind - just for the fresh sea breeze in the summer. With a Barrett and Forsling Exhaust, the brake upgrade was an easy choice. Ask about VGs for the RV-10 at OSH. Mil H-83282 provides another level of combustion protection. I have found that H-5606 tends to coagulate with age. Its low flash point is routinely accepted by most builders without consideration of alternatives. Some will yell "Stay off the brakes and learn Happy Feet". Then your neighborhood A&P will explain how proper engine leaning and a higher idle than 700 or 800 will cause the aircraft to move in a forward direction requiring those darned toes again.

    IIRC the blended airfoil winglets on B7x7 aircraft account for 3-4% fuel economy as well as lowered stall speed, etc. There are droop wingtips for aircraft such as hersey bar Cherokees and C172s that apparently are effective for stall reduction without too much drag addition.

    This is a first for me. I've used Cleveland brakes almost my whole flying life, and find them better than the alternatives. My only guess is that you ride the brakes while taxiing (give the brakes a tap or two to keep the nose pointed to where you want to go rather than constant pressure) ...... or your brakes don't relax when you release them. I'd check to make sure the brake cylinder rides on the pins freely. They don't need lubrication, which usually just gums them up and attracts dirt. Are the pads wearing evenly??? Uneven wear is a sign of the brake cylinder hanging up on the pins, or a mounting problem. Improper break-in could also be a cause.

    Yes I'll admit it, I would not add drop down winglets to my -10 if it added 15 more knots in cruise and washed itself when it was dirty. That being said... John have you seen the clear rubberized VG's on the Cessna Columbia's leading edge? Small in profile and difficult to see unless you are either looking for them or right up against the wing. Also interesting because they are on the forward most portion of the leading edge vs. typical VG's further up the curvature of the wing. Interesting item.

    Tim James #623 has done a major improvement in both handling and low speed flight with his VGs. Others might query at OSH and post their impressions here. The 10 can provide some great, short, soft, H DenAlt landings and unimproved surfaces with a few reasonably simple mods. For many who never leave the asphalt jungle, I understand.

    I asked this question a while back and got no response. I will try again as things may have changed. Has anyone used Stewart Systems Primer Sealer to prime the inside of their aircraft? It is water based making it much safer for the environment and the person spraying it. It can be seen at www.stewartsystems.aero. If you have used it, what is your experience? How does it compare to a two-part epoxy primer? I am tempted to try it, but would like some user experience reports prior to jumping into the water.
