Status: offline 		  Gentlemen, Thank you for ur positive comments, they are really appreciated. Well, I guess I'm pretty well set, but that won't stop me from perhaps picking up another one. I was going through my plane inventory( I have about 60 planes), looking at the kitted ones, and did find a plane that I completely forgot I had. Long story short- the place we are living in now, we bought and moved here 22 yrs ago. When we moved, I had everything that was built stored in a spare bedroom, piled high to the ceiling. All of the kits, and a few early ARF-ARC were in the basement. I'm finally getting around to that area, and getting it set up for my hobby room, and build location. When re-organizing the shelves, I pulled out a large box, that I couldn't see the label on. Well, I'll be dam'd- it was a Model-Tech Great Lakes biplane, ARC, already basically constructed. Now, by this time, I'm really getting hyped, and will start final assembly, and motor/radio installations next month. So, I can't believe I forgot all about that one. I guess with old age creeping in, and the total accumulation of planes and kits, one does tend to forget exactly what all is there. I'm now pretty anxious to get the basement hobby room under construction. It's not exactly the kind of weather here in Pa. to start, so I'll wait until March, when it warms up a little, to get started.
   I'll have to post a few pics of my other fleet of planes, all of which I love dearly, and really enjoy a relaxing day of flying with them. Many Thanks again guys- I'll keep u all updated. I'll get a video of the Aeromasters flying, as soon as the snow melts on our field. Dean

Status: offline 		I ran a small hobby shop back in the 70's, and sold quite a few Andrews kits.  In Dean's photos he shows a larger version, did Andrews kit this?  It's been a long time, but I can only rememmber one Andrews Areomaster kit.  How many different size Aeromasters are there out there?

Status: offline 		   BW2, w8ye, and Trisquire, Thanks for more info on this plane.  I just wanted to pass along a little more info about what I found. I took every measurement from my std 52" Aeromaster, including- W/S- fuse length- aileron size- rudder size- stab size- incidences- L/G height- both wing Chords- lower wing dihedral etc. I then calculated the difference in size between the 2, and checked all the same measurements on the larger one, and this one is about as perfect as u can get, in comparison .Now, what I don't know, is if Andrews started kitting the larger one 1st, or Great Planes started the larger trend. I've never seen a kitted large one before from GP, so I wouldn't know what their kit was like. The fellow that built my large one, had built around 40 of these original AAMCO kits, and at least a dozen large ones for a lot of flyers from several different clubs. I remember seeing him fly his 1st big one, and it was as beautiful a flight as u could ask for- No bad tendencies, very nice scale aerobatics, and  perfect takeoffs and landings. He powered the 3 he had of his own, all with the older canted valve head OS120- 4 stroke, and they were never underpowered. I know he had a really nice array of jigs he built to build these, and his workmanship was nothing short of outstanding. I looked at the structure of my smaller Aeromaster, and compared it to the larger one, and every stick, and piece of balsa was absolutely exact on each plane.  I'm just wondering if GP cheapened the kits they produced, or made any design changes from the original. Seems that someone mentioned that GP made a change on the turtledecks on the ones they kitted. Who know what else they may have done, but mine is an exact replica of the 2 smaller ones I have.
    The only thing I didn't get a chance to do was weigh my big one, and I'll do that tomorrow, and see what it weighs, without the radio gear, motor, and fueltank.   Is there anyone else who can chime in on having, or flying the big Aeromaster, and what motor they used, and what their results were.   Thanks again Dean

Status: offline 		Here's a photo of my Kadet and my dad's Aeromaster. He built it in the early 70's. It had been hanging around in his attic for about 30 years until I brought it home and put in my attic for about 5 years. I pulled it out last year and pulled the guts out, put in a Super Tigre 61 and have been having a blast. It is way to much airplane for me and I am rebuilding the landing gear as I write this. The photo was taken last fall.

Status: offline 		I just bought an Aeromaster at our clubs auction yesterday, it is version 3, with both wings 52" and swept back, It came with an os 91 four stroke installed, I have read the first 7 pages of this thread looking for the cg placement, I will continue looking unless someone knows off hand what it should be. I am looking forward to flying it this summer.

One more question, I assume that standard servos would work on it, is there any need to upgrade servos?

Thanks

Jon

I hope this will be the fuselage file.

The CG is shown on the side view about 1/2 inch ahead of the rear vertical cabane wire.

With both wings swept back, I've had good luck with the CG being as far back as the rear vertical cabane.

Status: offline 		Thanks, on the wing files, it said to have it 1/8" forward of the rear cabane, and that is where the plane balanced when I put my battery in. The plane has been loved and used a lot and it shows, but I don't mind at all, I am going to replace the servos, re hinge the rudder and fly it. ))

Status: offline 		I found my No3, with the balance as on plan, 1/8 in front of the rear strut, was able to be rolled onto it's back, and fly without any forward elevator required. It was however, very sensitive to inputs. I moved the CG a wee bit forward of that for more comfortable flying. I suggest you add a little weight up front until you are confident with the plane, then work the CG backwards slowly.

Status: offline 		Minnreefer, Saw the Aeromaster at the auction. You have a great airplane although a little used. I have a short wing version with only an OS 46 and it is a great performer. The only mod I made to the airplane was to increase the size of the rudder mainly for appearance sake. I am not sure if it changed the flight characteristcs as I have no starting point to refer to, but it does knife edge from horizon to horizon. If you are rehinging the rudder, you might consider making a new larger rudder. With the 4 stroke 90 in yours, it should be quite the airplane.
I have an Aeromaster kit stashed away and will be building it as the long double swept wing version with a Saito 90.

Status: offline 		Hi pd1

Here are the 2 fus files, I thought the C/G on the fus plan was for the 48in wing and the notes on the 52in plan for the other 3 wing set ups.

2 files ended up on my post as I didn't think my first try didn't up load ok.

By the way I found the plans first then this great forum and I am planning to start the build later in the year, but if the summer is anything like last year I may start earlier!!

I was thinking after reading some of the posts that I may build 2 sets of wings then one as the choice.

Peter

I might change the rudder. I do have a request, when you break open your kit, I would love to buy a copy of your plans, I would be happy to drive up and meet up with you to get them.

A good friend of mine has one and also has the giant one, he swears by them.

i am excited.

Jon

Status: offline 		A few years ago I wanted to learn how to scan large plans and stitch them back together again.

The Aeromaster plan that has been shown is one of my early attempts at scanning, there are a few errors.
I originally posted the plans on another web site and the plans grew legs and are available on a lot of web sites now.
I know that these plans were my scans because I cut the plan into smaller sections to facilitate scanning and printing.

Here is the latest updates on the Aeromaster plan, with all the errors I could find corrected.
I also added measuring scales on the plans so the accuracy can be checked quickly in two directions.
The file can be downloaded and brought to a print shop like Staples and they can print them full sized.

I know that one can blow up and make things work, but it is nice to work off orginal or good copies of plans, but no knowing what you said, I am excited to be able to build another in time. I am a strange creature, if I feel that I can replace something, then I don't worry about flying it as much as some planes that are almost impossible to replace.

Jon

Thanks again, this really is a great hobby with great people.

It is supposed to resemble the Jungmeister flown by Alex Papana in the 1936 Olympics. http://www.fantasyofflight.com/aircraftpages/jungmeister.htm

Status: offline 		PD1 is a great guy and a fine craftsman of Lou Andrew's designs! I met him at a vintage meet a few years ago and was very impressed with his P6E version of the Aeromaster. I too have a couple of Aeromasters to get airborne. One is a refurb that's at least 30 years old, it's just about ready to recover. The other is an unflown airframe that needs a radio installed.

Paul: I got this airframe from an old timer on Long Island. This version is a one of a kind that the builder claims was built from some "pencil drawings" that Lou had sketched back in the day. Can you shed any light on this claim? While you can see that it is an Aeromaster, there are some subtle differences. If I get a chance, I'll post some pics tomorrow. Thanks for any input.

On a side note, if you ever run across an Aamco Sportmaster, get it. It has the same sweet flying characteristics as the Aeromaster. I have one dedicated to floats and another still in bones to be set up with wheels. The Sportmaster makes an excellent float plane.

The Sportmaster is another set of plans that I am keeping my eye on, I found the one that you are talking about ama plans #23948, I might have to order that one of these days.
