Hi! Eric,
Do you know, it's a real pleasure to get such marvellous response from a software producer such as your good self. Since purchasing your software the few queries e-mailed to you over that period have always been responded to with the utmost urgency and never failing solutions. The larger organisations could certainly take lessons from you. Thank you very much Eric the file worked a treat. The software disk will still work with my desktops running Windows ME and 98 2nd edition I assume. Thank you very much Eric, what a Wizard you are.
Kindest regards,
Roy Yates

I appreciate all the help you provide at what seems to me the oddest and most unusual times. You have my vote for the best supported software in ANY business. I should know...I provide technical support as well. Thanks again. If you don't hear from me soon, happy holidays to you and your loved ones.

Thank you for your return E-mail. I recieved my Compufoil 2000 today in the mail. I have it installed and have already used it. I am presently scratch - building a quarter scale Caudron C-460. I need to build the flaps now and they are not defined on the print. I lofted a set of nine ribs and printed them along w ith a planform for BOTH flaps in less than 15 minutes on my first try. What a time saving and powerful tool!
I've barely scratched the surface and I already love it.
Thanks again ,
Great Stuff !!!

Dear Sir, Eric,
I would like to send this mail to express my sincere feelings about the service you deliver from the start to the end, when contacted about your product CompuFoil 2000. This is great and does a lot to show that buying through the World Wide Web can be save and fun! Moreover the product does exactly what is promised and the after sales support, if needed, is fast and to the point! Thanks!

I can see that I am eventually going to want the option that allows me to m odify the thickness of the airfoil. I don't think that I have it.

Eric, I must say that I am astounded. I emailed my support request at 1:09AM 5/5/00. At 1:32PM 5/5/00. I received by email a brand new version of Compufoil 2000 with the functionality I needed implemented. In just over 12 HOURS (!!) you provided me with what is an essentialy custom upgrade to a professional-level program. This upgrade was also posted on the web for the use of others on the very same day. In an age of faceless corporations and brain-dead "customer service representitives" this is truely outstanding customer service!!
Please rest assured that I will remain a loyal customer of your program, and that I will do all I can to see that my fellow modelers know of the incredible product and service you provide.

Don't suppose you're interested in designing a CAD program for fuselages that works as easily as compufoil? I'm reasonably computer literate, but have a hell of a time learning CAD. Bought ModelCAD (sucked) and DeltaCAD (better, but...). Frankly, I just don't have a month to invest in learning this kind of stuff. However, the learning curve on your program is about 20 minutes and I applaud you for it.
Thanks,
Larry

Hi Eric,
I will have to get you an order for your Compufoil. The (Chuck Anderson) Design8 program has too many problems with it right now, and he is unable to make the changes for a while (I think his beta testers led him astray). I was going to go out to your web site and see what the options were, and see what I needed to order, but like you said... it isn't working. I'll check on Monday, or with you, and see what I can do.

Eric, I cannot say enough good things about your product and your product support.  You have helped me out so many times as I went through my computer and CompuFoil learning curves.
As I've said before, you have a GREAT product.  It works so well and I really consider CompuFoil to be the best software money I have spent. Compufoil is one of the 2 or 3 programs that I use the most and I am lost without it. And if something doesn't go quite right, there YOU are to help get things working properly (thank you for the phone call, my jaw dropped to the floor.  Talk about unexpected). And what other vendor (programmer) continues to give, what seems to be, free, unlimited updates (don't go getting any ideas here).
You are a perfectionist.  And for that I, and all, CompuFoil users are extremely grateful.

And here's the disclaimer. I never have talked to or met Eric Sanders. And I don't work for him but I'll tell you this, this is a first-class program and more of the software companies should make a product that works half as well.

I'm sure I'm not the first to tell you what superb piece of software you've created. Thanks to you, that dream RC plane with that impossible modified eliptical wing will now take shape. Thanks a bunch.

Eric,
Once again you have demonstrated why CompuFoil is the best airfoil software on the market today. Your service and support go beyond normal customer expectations. Take it from one very satisfied customer who is glad to be called a CompuFoil customer. You deserve our loyal support for all you have done for those of us who use your software. Thanks again, Eric. You continue to raise the standards for top-notch products and service excellence in this hobby.
Best regards,

Dear Mr. Sanders
Many times the only time an individual or Organization is contacted is due to a problem with their product. Fortunately, for our firm, of this is not the situation.
This letter is to complement you on your software, and the outstanding customer support you have furnished us. the CompuFoil professional airfoil editing software you provided has exceeded our expectations, and is aiding us immeasurably. I hope you will continue publishing software of such high quality. Thank you.
Sincerely,

I just wanted to let you know that the latest version of Compufoil for Windows that I am running on my Macintosh (via Soft Windows) is working great. I am sure that you hear this often, but Compufoil is a really fantastic program! Great effort! Keep up the good work!
Best regards,

If you remember, I mailed you some time ago about purchasing a copy of Compufoil (your reply was dated June 18). I'd now like to go ahead and order! I've tried one or two other demo packages (notably WinFoil) - they're dire by comparison.

Compufoil works GREAT. I love the program and I recommend it whenever someone askes. A quality product and I commend you. Finally, here is a program that works as advertised and installed on my computer EASILY.

Hi Eric,
Matney's Models has been using ComFoil Pro for the last 4 Years. It helps when a new design comes out on the market. I would be lost with out it. We cut Custom Cut Cores for a lot of customers. They send the airfoil they want in the mail or email with a drawing & I send then Custom Cut Cores. Keep up the Good work.

Hi Eric,
I loaded the eh foils into your program and it works great. Compufoil is one of the best investments I've made in RC soaring! Thanks.

Hi Eric!
First thank you for such a piece of software. Following your simple tutorial on foam wings a have noticed a clear improvement in my lastest three wings;and my friends too... :-). Defenetly was worth the investment.
Thank you very much for your help and let me congratulate you again for your software. Thanks,

Hi Eric,
I have just upgraded to 1.21, I am still using CFW as the only wing design tool for BIG ED's HOBBIES, my only complaint is that after the wing the fuze takes too long 8;-))), seriously, the software is a delight, the ability to export dxf files alone makes it a must buy, but add in the ability to loft a complete set of ribs, magic, we are selling two newish models, a twin of about 90" wing span and a single about the same, the flight charistics??? are great, which I believe it due to the ability of compufoil to fine tune a rib to my specs.
Again Eric, thanks for a fine product and great service.

John,
You can't go wrong with Compufoil! It will generate templates specifically for the feather cut machine if you want it to, or do about anything else you can imagine. Eric Sanders' customer support is absolutely the finest I've experienced in the RC sailplane industry. Contact him at CompuFoil@aol.com He's even got a site for a demo version of the program but I don't remember the URL. This recommendation is brought to you by a very satisfied customer.

It is truly refreshing to find someone who is willing to provide the kind of support after the point of sale that you have provided. I know that there are competitive products that are available, and for that matter, I own one of those products. First of all, let me tell you, from my personal experience the competition isn't competitive in any aspect that I have been able to discern, including, the biggie, ease of use!
Again, my thanks to you for a Great product and fantastic support. Between CompuFoil and feather cut, I am having a great time.
Thanks again,
Spalding

Hello Eric,
It was well there, on spot and on time!
I just run thru it at home, have to make a clark-Y for a friend, and
I say, it`s not as good as I expected,as I expected far less,No it`s
outstanding! What a complexity .
I`m also very pleased with your build in conversion cabability from inches to metric, saves me a lot of time (and errors)
Thanks once more, looking forward to hear from you
Greetings

Hello Eric,
Im not a person to contact a software mfg and coment on their product.. I have witin the past two days upgraded my compufoil to your 98 ver. I am both thrilled and elated with your new version...I have been using compufpil a few years now....Now to have the ability to print out a full size wing plan on a printer is truly a super achevment....especialy an eliptical one......to draw one on a drafting board has always been difficult for me the math involved has always been a pain...you have simpified it with the push of a button.....also the placement of jig rods is truly more accurate The addition of trailing edge tabs s also a great addition,,,,,True the program isnt a low end one....Ive added a couple of hundred more cor files in addition to the purchase of your library....with this addition my choise is endless my prog is only lacking the dfx addition.....to be full blown......Again i want to thank you for the quantum leap in your new 98 ver.....I personly will trumpet your program to friends and fellow club members..................................

Hello Eric,
I received the program disk last Saturday and WOW!!!!!
I think that I will find new things to do with it for many years to come. The following is a short list of the projects that I will use CF Pro 98 for.
1:3.5 scale Minimoa (194 in.)
Another Alcyon
A scratch Bird of Time
A TD ship called the Gambler Designed by Keith Smith
Just to name a few!!!!!
Keep up the good work.
[Insert a pat on the back here]
I will have some questions just as soon as I find one that the help doesn't answer.
A fine Program!!!!!
A very satisfied user

I install the "patch" you send me this week end and it works fine. I finished designing and plotting my wing (ribs structure) and begin to build it in one day! your software is incredibly efficient. For plotting, I use rool paper on my Epson Stylus 800 (which is normally not designed to use it) and I define a custom page format equal to the half span of the wing... no cutting/glueing needed!
Best regards et "à bientôt"
Patrick

Hello Eric,
I just now downloaded the new auto updates for Compufoil98, and I just wanted to tell you once again how fantastic this program is. Since using your program we have decided to experiment with some new airfoils and two new champion sailplanes are born. Thank you very much for all you have done to assist me with past questions and new updates.
Take care
Happy Turns

Thanks Eric,
Used the James Allen # and works great. Keep up the great work. Powerful tool. It helped me design the fastest Q500 plane there is. My partner has the new national record at 1:05.20 with an airfoil I developed with your software.
Thanks
Jim Allen

Eric,
 This is an outstanding program and well worth the investment. In one afternoon with no prior experience with CompuFoil, I was able to generate individual test ribs for the dragonfly slope glider I am scratch building. This almost makes generating all those individual ribs fun.
Thanks again for the help
