of a kind design based on a larger original MIA model done in the 80's,
but made smaller and more realistic controlled via the MIA Robo Pilot an
MIA Innovation that started with that first 80's MIA Original Design RC
Microlight Trike, at a time where there were no such RC models available
Following is one
of the first Threads and posts I started in RCG long before interest
started to catch on by others and similar rc trike, microlight forum
threads and videos showed up on You Tube. Here is the opening
post, with typos and all.
Model was designed for weight-shift control via the mechanical pilot
who's hands has special ball links to the control bar (Note the ball
studs on the control bar, they were for this purpose) . The model was
also controlled via the more traditional 2 servos to wing via two rods
coupled to an original and unique mechanism part of the universal joint,
directly under a "floating crossbar" which also aided in providing
billow control to effect weight shift control.
material for battens, simple wood soaked in water and bent over a curved
also used lightweight bent aluminum battens but these did not retain the
shape as good as the formed wood ones. The model only used 3 battens per
side, strategically placed on the wing to provide an cambered airfoil
while maintaining a light "uncomplicated" wing.
original RC Microlight Trike Upper wire connections. I got a bit
creative and used sewing materials (The clips) along with
aluminum reinforcement plates at the floating cross-bar to LE
connections to make collapsing the wing easier for transportation.
Rip-stop nylon sail, reinforced with heavy Dacron tape at the Leading
edges and sewn with heavy duty button thread provided the LE pockets.
of my reference for this model was taken from an Air Creations Real
Trike Product Brochure I had requested via "snail mail", at the
time. I was not after replicating every last detail of the real trike as
my main goal was to make the model flyable and controllable via the
unique Robo pilot. I also wanted this trike to look original with my own
creative details. If you really look carefully at the way MIA Designs
products, "the details" you will find that these have their own style
and no other product or model is similar to mine in that respect.
Top Hat on Fiberglass King Post with stainless steel cables connected
soldered crimped brass ferrules. I never liked this arrangement for
the complexity in having to assemble top as well as bottom (AKA Ground
and Flying) wires, reason why most of the later and more recent MIA Trikes, Microlights are of
the Strut-Braced wing type, as this is much simpler and modern day
microlight trikes use it also for efficiency, less complex and less drag from all that
Unique aluminum frame perforated on a small millingmachine to remove
some of the weight. The unique MIA Trike frame design had to be modified from the
typical real frames design of the Air Creation trikes at the time, to
make room for the particular type of motor mounting required by the RC
counterpart. An Astro 15 motor along with a Jomar ESC powered the
model. Some of the electronics were removed to be used on another model,
at the time of this photo. I sold this model with no electronics as I was trying to
clear some large models from my garage in 2000. I regret having
sold it, as the only reference I have of this are these early photos.
This model played an important role on later MIA developments which were
actually less complex in efforts to provide a simple kit to the hobby
market back in 2002.
Following are some Pre 2009 models that I never made it into kits
because they were too complex to manufacture.
again another model with redundant upper and lower wires and a bit more
scale with non mechanical pilot. Weight shift via 2 servos at the back
of the main post to wing. Very similar to the controls on the current
MIA EZ Trikes and Gyros but also on the 2009 prototype park flyer MIA
again a similar weight-shift pre 2009 RC Trike Microlight with
original and unique control from servos to control bar. I had to try all
sorts of control configurations I could think of in order to make a
final decision on the type of control I wanted in a realistic "entry
Trike kit. Note the, also, unique types of universal
couplers from the frame to the wing at the CG points.
an RCG (also posted this in RC Universe at the time), a much refined and
simpler model that used my own design wing warping which I developed
after watching falcons glide over a nearby mountain and looking at
the way they would tip the wing tips to effect up-down and controlled
turns. After this project I spend some time away from my forum
RC Trike threads, as I had other commitments and real work
with the MIA Micro-Heli Kits and later Micro Heli upgrades I was
doing heavily at the time. But the idea was to provide a
simple kit from any of my previous weight shift and direct to steering
bar control designs. At this time Li-Pol and BL motors were still in
development stages and another reason why I was designing really simple
and extremely lightweight microlights was because the only form of
lightweight battery were still Ni-CADs Ni-MH, mainly. Heavy by today's
Li-Polymer battery technology.
LI-Polymer Batteries and BL Motors opened up a whole new world of
possibilities for these models and is reason why I decided to make
available the more elaborate MIA Robo Mini Trike, while also looking
forward to offering some of the more simpler but more in scale MIA EZ
Trikes. As seen in MIA"s countless You Tube Videos.
2009 prototype park flyer MIA Roto-Trike
This model was designed to
be a non Rogallo Delta (More triangular wing like a kite) shape but
more of a higher aspect ratio wing design, as most of MIA RC
Microlight designs, but geared to be both a Microlight as well as an
Autogyro by simply switching the rotary wing for the flex wing.
had posted this in the RC forums and on you tube in 2009. This model
was based on MIA"s much earlier Flex wing Trike designs that used 2
servos at the back for weight shift, and it made perfect sense to keep
the same frame and control architecture for both a microlight and
it had a vertical and horizontal stabilizer it was left there for the
autogyro features, mainly, as the microlight or trike configuration
never required one, as I had shown in much earlier videos of my
sail was a bit fluffy and supported by loose cables to
allow the model to inflate easily and maintain billow control via "2
servos at the back of the main post" (a shared design "weight
shift" detail between autogyro and microlight).
order to keep this page short and to the point,
am only showing some key MIA RC Trike Development historic points. I
have considerable photos and info imbedded in many or my early RC
Trike (Microlight) threads, and videos. To this day, there is no other
individual or company who has or is taking RC Microlights, Trikes,
Ultralights and Autogyros to the level MIA has and is taking them, and
this follows in the same tradition MIA took the RC Micro, Sub-Micro
and MIA Palm-Size™ Helicopters pre-2000, a
time these were only a dream.
