From: arjays@AOL.COM Hi Guys! First, let me say how much I enjoyed the "gathering". Thanks for allowing me to spout off my 2 cents about the extraordinary value of the group and the way to make it grow. (My belief is we must make it personal. Leave your own phone number on every Grumman you see with an invitation to call). Second, I'm wildly pleased that everyone likes our IceSkate design. You may know this is our #1 product for Cirrus Aircraft. Our design has a huge door for tire pressure and inspection, a cooling vent for the brakes, much lighter than stock (not hard to do), reduced drag, carbon fiber construction, 1/4 turn fasteners for fast installation and removal and an integrated strut fairing. (It's also very sexy. That's a feature I don't take lightly. If it does not look really, really cool, it offends our sense of design). This is a trial balloon. I need to know how many of us are interested. If the group is large enough I can do a product run which is more affordable than the Cirrus unit. The Cirrus SR20 version of our IceSkates sell for $7495. If we can get a group of 25 AA5's together we can make a deal for $5495 and if we can get 50 we can manufacture for $4495. The set will include all three pants, all three strut fairings, all new hardware, all brackets and fasteners, etc. It will be a certified STC product and can be installed and removed by the owner. So. Let's start a dialog. Whatcha think? Rj Siegel CEO/LoPresti Aviation Engineering ________________________________ Message 2 _____________________________________ Time: 01:57:18 PM PST US From: Gary Vogt Subject: TeamGrumman-List: Re: Jaguar Cowling installation questions Part 3 - engine thrust angle Bob, you are always so wordy. Gentlemen, gentlemen, let's not get your panties all in a bunch over this engine alignment. Boris (or whoever is interested) get on the internet and find a digital level. Find one good to .5 degrees. Now, go out and measure the engine down thrust angle every AA5, AA5A, AA5B, AG5B you see. Measure at the canopy rails, and measure across the rocker boxes. You will likely find, as I have, that the down thrust angle varies between 1.5 and 7.5 degrees down. I had a new customer come in with 1 degree up but his engine was obviously wrong (WRT the cowling). Bob, if the engine down thrust angle were that critical, we'd be given directions on how to keep safe. Bob, if the factory set up the planes so precisely, explain how there can be so much deviation between planes regarding the number of shims required to make the engine in line with the cowling. Also explain how the space between the firewall and the spinner can vary between 39 1/2 inches to 40 inches and still meet type design. Bob, 43.13 also says you can paint the back of the prop (the face) with black paint. Tain't so. The Sensenich TCDS specifically calls out Polane paint. Painting the prop with anything else makes the prop not in compliance with type design. Bob, you wrote, "The method we used before Gary sent out his cowl was to align the spinner with the factory cowling," What makes you think the factory cowling was right? Boris, the gap between the spinner and the cowling on all AA5x/AG5B airplanes is up to 1 inch. Most are around 3/4 inches. Mine is 3/16. With 3/4 of an inch gap, it really doesn't make a tinker's damn how square the engine is with the cowling. Who's going to notice? With 3/16 inch gap, you'll notice. Bob, you wrote " leaving it perhaps 3/8" high with new mounts, as they sag with age, and in a few months they'd be allowing the spinner to align very closely with the nose bowl." I'm sure that is your experience. However, I'm having Travis send pictures of his spinner/cowling. I installed his engine in 2000 with new mounts, set up the way I set them, and it hasn't changed in 11 years. Bob, I could argue with you and everyone else about the position of the engine in flight and while maneuvering. But, what's the point? Believe what you want. I designed the cowling to fit as closely as possible. During flight, there is about 1/4 inch between the cowling and the alternator. Alter the alignment from where I have it and all bets are off. Boris, your best bet is to trim the cowling as I said, install it without any muffler or baffles on your engine, and then align the engine to the cowling. ________________________________ From: b v ; n76lima@mindspring.com Cc: Barry Schulte Sent: Sun, May 29, 2011 7:28:00 PM Subject: Jaguar Cowling installation questions Part 3 - engine thrust angle Guys, Please take a look. I wonder if you could please help me regarding the spacers on engine mounts. I just bought a set of new Lord engine mounts. The old bottom ones were leaking and the spinner was sagging about 1/2 inch against the nose bowl rim. Now I have placed 1 spacer on each(as it was before) and torqued it per manual, 40 lb-feet. Before fitting the new cowl I tried the old one to check and found that engine is now hanging a little high against the nose bowl and a little to the right. Please take a look at the attached pictures. My question is - should I try to add spacers to align the spinner to the old cowl before I fit the new cowl, and if you think I should, then why? In other words, why aligning to the old cowl would give me a better thrust angle then relying on the angle provided by the engine mount together with the set of new properly torqued Lord mounts? Maybe I should try to measure the thrust angle? Gary, I think you had a method of measuring up/down thrust angle. Could you please remind me how you did it and what is the angle to aim for? I guess the left/right angle could be checked by measuring the distance from propeller tips to wings when prop is positioned horizontally. I guess one should try to make sure they are equal. Or not? Thank you, -Boris P.S. By the way, you have to remove the nose strut boot before fitting the new cowl. You all probably know it, but if you don't want to cut it off, you have to remove the nose strut. I think the installation instructions don't mention this. ________________________________ Message 3 _____________________________________ Time: 01:57:20 PM PST US From: Gary Vogt Subject: TeamGrumman-List: =?utf-8?B?UmU6IFRlYW1HcnVtbWFuLUxpc3Q6IExvUHJlc3RpIEljZVNrYXRlc+KEog==? how about some pictures=0A=0A=0A=0A________________________________=0AFrom: "arjays@AOL.COM" =0ATo: teamgrumman-list@matronics.com=0AS ent: Tue, May 31, 2011 1:41:14 PM=0ASubject: TeamGrumman-List: LoPresti Ice =0A=0AHi Guys!=0AFirst, let me say how much I enjoyed the "gathering".

Really for the life of me I don't understand where you are coming from Gary. I have absolutely no interest in manufacturing or competing on a cowling. You've got to be kidding! My exit ramps look exactly the same as your pictures Gary. Let me say that again, My cowl is the same as yours; the pictures look EXACTLEY the same. I have made no modifications to the cowling. I am doing a repair by adding length to the trailing edge of the cowling so that it can be aligned with the prop spinner. I don't believe am making it any longer than it was in its pre-trimmed state. I am just trying to get it properly aligned to my Tiger. Again I have made no modifications. If you had done a better job when you installed the cowling I would have had no squawks. Why didn't you check the engine alignment as I ask you to do before you installed the Jaguar? Would have saved a lot of grief. As to why my engine ran rough remember posting this Gary: "As for the plug wires not being tight, OOPs" That's kinda how I was looking at the whole cowling experience with you Gary....you just had a lot of oops... But your making false accusations about me to the FAA puts this on a whole different level. Do you really want to go to war over this? I see the posts we put here last fall where we discussed the poor fitting of the cowl have been removed. At least I cannot locate them here now. However, I do have pictures of how it was installed and how it was a poor fit. I have a copy of your emails wherein you agreed with me about this. I'm sure my FSDO inspector will want to see all this information should it actually go that far. Since you have made some kind of formal complaint to the FAA perhaps I should as well? Please let me know if you want to make something of this or if you will retract your false assertions to the FAA Gee Gary, I thought we were friends! When I flew home from your place with the new Jaguar cowl I found that it did not cool any better than the factory cowl and I posted this here. Later I found your safety wire "springs" broken. These are supposed to hold the under cylinder baffles together but they had broken and that is why it was not cooling better. After I replaced the broken springs with heavier safety wire I found and posted that the cowl did provide better cooling. I would think you owe me the courtesy of at least a phone call or personal emails before you go and make false reports to the FAA But maybe I was wrong to assume we are friends?

I bet you'll find the same thing. If not then my cowl really has a lot more defects than I thought." I really don't understand what your problem with the exit ramp is (or was). The bottom of the ramp is fabricated flat (with some curvature to conform to the cowling). The cowling has it's own ramp. The two are faired together when they are joined. It's pretty obvious. Here we go again "If you had done a better job when you installed the cowling I would have had no squawks. Why didn't you check the engine alignment as I ask you to do before you installed the Jaguar? Would have saved a lot of grief." OK, Ned, just what did you want me to align it to? As I recall, you wanted this cowling done and installed in record time. To help things along, to comply with your wishes, I used my plane to do all of the initial fitting of the cowling. All of the work trimming was already done when you got here. Your cowling fit great on my plane. I jeopardized my relationship with the FAA in order to get your 3 blade prop approved along with getting the airbox approved because I thought we were friends. They wanted a complete flight test to show the 3 bladed prop had no adverse interactions with the cowling. I called in a lot of favors and made a lot of promises to get your plane approved and finished as quickly as I did because I thought we were friends. I can get the cowling painted anywhere for $500 or less. I deducted $1000 from the installed price because you said you didn't want it painted. I gave you a good deal because I thought we were friends. And then you pissed and moaned about a $5 cam-loc you wanted replaced. And you wanted a different right forward baffle so I gave you one. I gave you a baffle that cost me $35 to have made. And then you had the balls to whine about a cam-loc? Seriously, getting upset because you didn't get the $5 cam-loc you wanted???? And the ONLY thanks I got from you was a report saying I forgot to tighten the plug leads (not, Gary was so stressed getting my plane back together that he forgot to tighten the plug leads), the plane was slower, and you weren't happy with the results. Then, on top of that, you wanted me to sell you another cowling at cost. Ned, nothing you've done or said since you left with the cowling has been or sounded like something a friend of mine would have done. In comparison, I have another customer who has gone out of his way to work with me when he wanted something done. If I don't have his plane ready, he either waits or comes over to help get another plane done so I can work on his. He has bought me $100 bottles of single malt scotch on more than one occasion, brings gifts for Clytie when he comes to pick up his plane, and gave me a $100 bonus because he said I didn't charge enough for the time I put into his wheel pants. In return, I sold him an eyebrow for $100, given him instrument panel overlays, and he will be getting the cowling from my plane for $1000 when I get the new one Dave is making for me. This customer has never asked for anything extra or asked if I can sell something to him cheaper or asked for anything for free. Unlike another customer of mine who comes in and loads up on bottled water from my refrigerator (putting it in his plane while he waits for me to get the plane out of the hangar), he's not a cheap bastard. He leaves $5 in the fridge if he takes some water. I like working with him. He's honest and doesn't expect something for nothing. I consider him my friend. I never posted that I HAVE reported you to the FAA.
