Default Aamco Minimaster

Due to the kindness of a member here, I now have some plans of the Minimaster.

I started cutting parts two weeks ago and the plane is ready for a test flight.

I worked at Aamco for a bit in the late 60's and early 70's. I also got to build the pre production one.
I always liked the Minimaster, it had some quirks, but it still could fly well.

When Lou started AAmco, the first planes were the H-Ray and S-Ray. These two shared a lot of common parts.
When the Mini was drawn up, it had a buddy.
The next plane was to use the wing and stab from the Mini and it's own fuselage.

Lou built the first proof of concept Mini. It had a non sheeted wing with egg crate construction for the spar and ribs.
The leading edge was to be a heavy shaped leading edge, similar to Sterling and Goldberg kits.
The first pre production wings almost fell together, a lot like his Box-Lok fuselages did.

When production started, all was not well. The heavy material for the wings relieved themselves once cut.

The parts were unusable.
Lou redesigned the wing, a new sheeted wing took it's place.
This took quite a while because there was a six to eight week wait for new balsa to arrive.
The plans had to be redrawn too, also time consuming.

The first and only run of Mini's started in the new facilities, another hassle.
The run was 3, 300+ kits. I don't remember the exact overage.

I got to build the plane for the photo aid sheets and to double check the parts fit.
Basically it was the first one from production parts.

The plane didn't sell well.
A few people had problems with snap rolls on takeoff.

The plane was in a transition period. A lot of people had proportional radios, but a lot that bought the Mini still ran reeds.
Reeds and heavy servos made the plane overweight, and the current philosophy was for takeoff hold up elevator till it broke ground.
This often resulted a snap roll.

Enough history here's my latest plane ,2 pounds 12 ounces ready to fly.
Oh, and electric powered.

Nice job - Another airplane I always wanted as a kid!

Brushless motors, li-pos and tiny radios allow these older designs to reach their potential. Russ Farris

I remember the one I had. I had powered it with a new OS Max .25. This was before the FSR's came out. It flew great but you had to be careful landing it. In the air, it was a "rocker", rocking side to side. I cured it with reflexing the ailerons up about 3 or 4 turns. That cured that. I finally lost it when it snapped on landing and little was left. That .25 was a good engine and I was often asked if there was a larger engine in it.

pd1, you are right about the snapping! i lost mine in 90 or so when a friend kept snapping it trying to recover from a dive.
i finally found a kit and copied he plans and blew them up to 74"!!!! what a nice plane! i covered it in dark red and platnum with a
phoenix 6 checker pattern. always liked that scheme. i put a 65 LA in it and it was a bullet! only problem was that the fuse at the tail was too narrow and the tail feathers blew off on the third flight! man what a heart breaker! it was a beauty! first time in over 40 years of modeling to have tail feathers blow off!
my good friend Dan Hines in N.C. now has the kit.

That's an excellent job on the MiniM as well as the the other two in your pics.

I soloed on the TrainerM back in 78 when I lived in Taft Ca. it was a good flying plane for me with little skill back then.
Trying to collect most of Lou's designs over the last few years has been fun and costly, I wonder if he ever thought the the H-ray or Trainermaster would pull the prices they ere now.

Thanks for the bit of history as well........... Dan
