About this Plan
Aeromaster. Sports biplane for radio control. Wingspan 48 in.
Quote (from plan): "The Aeromaster has exceptionally fine ground handling characteristics, and does not easily ground loop. The Aeromaster is a very docile and easy to fly model that can also be tossed around and made to perform almost violently, if desired. It has a very clean and semi-fast rate of flight speed and the speed is rather constant during maneuvers.
The Aeromaster also has a fantastically high glide ratio both in a dead stick approach or low motor approach and has to be slowed down by inducing angle of attacks in a three point landing approach. The Aeromaster can be brought up much higher on angle of attack then just menyioned without stalling out if desired. Two wheel landings can be had after first slowing model down with angle of attack and then rasing the tail just before touchdown. If you have anough room such as at big contests, long low angle of attack approaches can be made with either two or three point landings.
The model is extremely stable during landing maneuvers and also very responsive to all control surfaces except rudder. The rudder is most effective during maneuvers such as wing overs, spins, knife edge flight, etc. But a little slower on most maneuvers and actually you don't ever use rudder except for these maneuvers or to steer the model on the ground if the tailwheel is attached onto the rudder. Ailerons are used more than anything for most maneuvers combined with elevator and motor control. If coupled ailerons and rudder are used, allow only about 1/8 in movement left or right at end of rudder with full movement of ailerons..."
Note this here is the standard Aeromaster. See Aeromaster Too (oz1972) for the extended wing version.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsSteve, This is a picture of the original Aeromaster by Lou Andrews the designer. The second picture is of Ernie Huber's Aeromaster, this was built at the same time as Lou's Aero.

I built one of these from the kit in 1972. It had Sprengbrook radio and a Merco 61 engine. I built the big-wing "too" variant. It was the best aerobatic machine I ever had in twenty years of model flying. Sold it complete with all my gear in 1973 to pay for the honeymoon! - BAD DECISION! Thanks for a wonderful website.

Built one of these in 1974....flew it thru the 1980s when a fire burned up the wings....just bought a new kit on eBay and expect it to be back flying in about a month.....a forty year old plane....always was my favorite....had a ProLine radio and an Enya 60...

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
