TOM MARTIN FREQUENTLY ASKED QUESTIONS...

WHAT IS AEROSENTE?

Aerosente is a Northern Illinois based manufacturer and distributor of vintage and classic scale sailplane kits. We offer a full line of wood gliders and sailplanes starting with simple hand toss gliders and culminating with vintage and classic large scale sailplanes. Our kits are designed and or adapted by folks like Tom Martin, Tom Bode and Tony Elliott. We also offer a nice selection of Frank/John Zaic, JASCO/JETCO kits from the golden age of soaring. Mike Smock and Tom Martin are the proprietors of the Aerosente NEWS FROM Glider Workshop. WHY WE DO THIS

This is a hobby and a business for us... a labor of love (nobody in the business of selling kits is in it for the money, at best you squeak out a modest income doing this). We started Aerosente because we love sailplanes - especially classic and vintage versions. We love building them and flying them, and Aerosente is a way of sharing this hobby with others. So what we’re saying is that we are not Nordstroms nor are we Amazon. We don’t have millions of dollars invested in technology, We don’t have operators standing by to take your phone calls, we are not ISO 9001 certified and we are not your servants. eW don’t look at you as a customer or a business transaction, you’re a fellow enthusiast and over time perhaps a friend. THE SHOP THIS PLACE IS A LITTLE MESSY ISN’T IT? If you spend any time on the Aerosente web site you will see that there is a lot of stuff there. You will also notice that it is a touch messy, not unlike our shop, but if you give us a minute or two we’ll generally find whatever we’re looking for. It is not unusual to have a visitor spend several hours on the site reading articles and looking at the photos. Most of our kits come with a lot of detail published on the web site. Detail like manuals, build logs, historical photos, documentation, videos, etc. Publishing all this content comes with a hazard - it is difficult to make sure everything is up-to-date and accurate. So from time to time you may stumble across something that is inaccurate or out-of-date - for example when we update all the prices or contents of our kits we may miss a couple of old prices or spec’s. If we do miss something we’ll notify you to let you know what the new price is or how the kit contents have been modified and then give you the option of continuing or refunding your money.

IF YOU DON’T LIKE TO BUILD THEN YOU WON’T LIKE OUR KITS DECEMBER 2011 If you’re looking at building a scale model for the first time it is important to understand a simple dynamic. eW do this because we love the building process at least as much as we do flying the aircraft. If you don’t like to build or you are expecting a model that is almost ready to fly then you’ve come to the wrong place. It’s interesting to hear some guys say “why would I pay hundreds or thousands of dollars for a model that I then need to spend hundreds of hours building?” Well the answer is simply because we like to build. Building is entertainment for us. Flying is fun. When you pencil it out, compared to other forms of entertainment - building scale models is darn cheap, and your It’s Christmas! As I write the winds are blowing off the lake wife will always know where she can find you! at 40 mph.

If you’re the fussy type that needs everything to be perfect then don’t get started building scale kits. Or, if you’re the type that actually reads the instructions before you Christmas with friends and family. I hope you and yours put something together then don’t get started building scale kits. While some of our kits have manuals, most do not and require the builder to “noodle” things out on his own via the plans, build logs and interacting with the build community. All our kits have been designed by other hobbyists, not aerodynamic engineers - which means from time to have a happy holiday! Merry Christmas and a Happy New time there will be errors on the plans or the parts that you’ll need to correct. Most of the time we point these errors out - but not always. Year from Tom and Mike! WE ARE ALWAYS AVAILABLE BY PHONE OR EMAIL The reason we mention everything above is to make sure you understand what you’re getting into before you order. If you have any questions or potential concerns before you order then please give us a call at 415.246.4337 or email us at [email protected]. After you’ve ordered if you have any questions call us or email us. Remember what I said in the first paragraph about “not having operators standing by”?The reason for that is because we take all our own calls and answer all the emails. Generally speaking In this months issue I interview Tom Martin who goes in- we try to take all calls as they come in and I respond to all emails the day we get them. We do ask that you not leave voicemail. Some of you will call and leave a detailed 5 minute voicemail that requires me to write stuff down and listen to it several times to understand what you said. Instead send an email. We check email about 10 times an depth on how he designs a new kit. We have some last min- hour. ute Christmas gift suggestions for you and several new WHAT COMES IN A KIT? We sell skinny kits and fat kits. Skinny kits come with the plans and laser cut parts only. Fat kits come with laser cut parts, canopy, instrument panel, hardware and plans products including our Chuck Gulls. Last, to assure delivery - each fat kit is a little different so check the kit specs to see exactly what you’re getting. You will need to buy the long stock (spars, stringers, leading and trailing edges) and wing/fuselage sheeting, miscellaneous hardware and covering. Some of my kits have a detailed “buy-out” list for all the additional parts and pieces you need to buy, but many do not. We always recommend that you wait until you have the plans and the parts in hand before you do your buy-outs.

Most of the time within 7 days of placing your order. Pinpointing the exact date is impossible because of how we run this business. We try to batch our orders, packing and shipping. Which means the date your order ships is contingent upon how many other orders we get and when we get them. We will not call you when your kit ships, but we Thanks for reading! will email you the shipping information so you can track your order. MIKE & TOM WILL ANY OF MY PARTS BE PLACED ON BACKORDER? Everything should ship within 7 days of your order except for custom fabricated parts like canopies and instrument panels. From time to time our suppliers may extend their Proprietors deliveries to us which will require us to put items on backorder. We try to keep stock items on custom parts but we’re not always able to match supply and demand. If we’re out of stock then it should generally be another 30 days before the item ships out. Because canopies and instrument panels are installed towards the latter part of the build The Aerosente Glider Workshop this isn’t a problem. Please call us or email us [email protected] to confirm if you have any concerns about backorders. Island Lake November 2011 WHAT ABOUT RETURNS AND REFUNDS? As I said above we are not Nordstroms - we can’t offer “no questions asked returns and refunds”. Because of the nature of the kit business it is very difficult to accept returns because of the hassle of repacking them, shipping them, and then being able to return them in good order to stock. Which is why we have attempted to explain in detail what you get and what you don’t get from Aerosente. Because of the delicate nature of some of the parts from time to time the shipping process may damage some balsa parts. Most of the time you can repair the damage with a little CA. If not we’ll cut and ship replacement parts. If anything is missing from the kit we will ship it out to you as soon as you let us know. Beyond broken parts or missing parts, if you just want to return your kit they we will have to charge a 20% restocking fee and you’ll need to pay for shipping. Once we get the kit back I’ll refund your payment less 20%. Visit our company store at www.gliderworkshop.com where you can browse from the hundreds of products that we now offer. And of course should you have questions at all call us at 415.246.4337 or email us at [email protected].

So this month I take on the task of interviewing my business partner and co-proprietor of the Aerosente Glider Workshop Tom Martin.

Tell us about yourself:

I was born May 1, 1955, the second son of an aeronautical engineer and daughter of a civil engineer working for the City of Los Angeles Water Department. I lived with my family of two brothers and two sisters in California’s High Desert which was the heart of early flight testing.

Your father was an interesting man - tell us about him:

James A Martin graduated Notre Dame Uni- versity in his hometown of South Bend Indi- ana and was hired by North American Avia- tion in Los Angeles, CA in the early 1950’s to development supersonic and transonic rocket powered aircraft, culminating with the X-15. In 1953 he was hired by NACA to manage the research flight program of Tom Bode (on the right) at that aircraft at Edwards Air Force Base Wasserkuppe with his Ka6e (http://en.wikipedia.org/wiki/Edwards_ about to be launched.

I use the same font family and only three or four font sizes for the entire drawing for consistency and the same holds true for line weights. All interior parts outlines are in a medium weight line, leader lines and fiduciary lines are drawn in a lighter stroke, and outlines of complete assemblies are in a heavier stroke approximately twice that of the interior lines.

The final step in developing a plans is to add all hidden or dashed lines, check all of the plans for accuracy, run the spell checker and then group the graphi- cal and text elements for each detail, parts template grouping and major as- sembly make any other subtle changes in those elements position on the sheet for the best overall look and fell of the plan. And lastly plot the drawings and review one more time from the printed pages making any last minute correc- tions or improvements and catching and correcting any errors that were not apparent while working on the monitor.

The bill of materials and specifications are then taken from the plan itself to provide information to modelers about the model as a product. The Bill of Materials consists of a list of all the material pieces that they will need or that will be supplied with the kit to finish a build. The specifications are made by measuring span, length and height overall, span of tails, area of wings and projected weight and wing loadings along with the airfoil and number of servos that will required at minimum and maximum to provide the desired functions.

One last question - what are you working on?

I’m building a 16 foot McKenzie Drift Boat, designing a scale Sisu 1A kit and low cost wood slope sailplane kit, and I’m drafting the Briegleb BG-12B 1:6 scale and a Franklin PS-2 1:4 scale while complete two beta builds on our Piper Brave and the LT-IV.

Ok. Thats is for this months interview. Hope you enjoyed it.

The hot finger! Titebond 3 is my glue of choice for 99% of my model. If a sheet pops up and refuses to lay flat at a joint, Titebond 3 will iron down flat miraculously with this little iron. I’m not quite sure what the window of time is on this pro- cedure but I have ironed joints flat after about eight hours. What a great property for a modeling glue. Just iron the nasty part down and hold it there with a real finger until it cures and give thanks that you don’t have to rip the offending sheet off. Available from R&F paints online.

I nick my curves with knife occasionally but try not to. Over time your curves may be needed to be replaced. (Some of mine are 60 years old!) If a panel is to be steam bent over a tea kettle, attach the paper pattern onto the plywood after the oversized plywood shape has set. A curved panel can be accurately cut to size over a piece of wood like a shoemaker’s buck. (When steam bending, I use butcher string to hold the steamed plywood over dowels, wine corks, ping pong balls, etc. If you humidity is low in your work environment the panel will be ready to use in about an hour.)
