|1. What is the airfoil section?
||The closest description is "Modified Rose Parakete"
|2. What is the chord length?
|3 What is the thickness of the main spar?
||The Micro Mong uses aluminum tubular spars. They are
6061T6 extruded aluminum tube of .083 wall. Front is 2 1/4" diameter.
Rear is 1 3/4' diameter
|4 Is the aircraft buildable as a true part 103
|| The orinal design proto type Micro Mong was
constructed and originally flown as a "leagal" part 103 ultralight by making
use of many calculation provissions of that rule. Though theoretically
possible, constructing a Micro Mong to fit within the boundaries of part
103 is not recommended.
|5. How long does it take to build a Micro Mong?
||This depends on builder's skills and equipment. Also
whether building from plans, or kit.
From Plans, figure 800 to 1000 hours. From kit,
building time will be approximately one half that amount.
|6 Does the micro mong go along
with german rules ?
| The Micro Mong has not been evaluated for any
government rules. It will fall well within the Experimental Homebuilt
category for US registered aircraft. Though it certainly would fit
within regulations of many other countries it has not been officially submitted
for such evaluation.
|7. I am 6Ft, 250Lbs, will i fit?
Empty weights have been observed to vary from
around 350 lb to 410 lb using the Rotax 503 package
as described at http://www.greenskyadventures.com/MMengineinstrument.htm
If a 250 lb pilot flys a 350 lb Micro Mong there remains
50 lb for Fuel and baggage, and still remain within 650 gross weight for
Normal Category operation.
|8. What is the wing construction?
Aluminum Tubular Spars
Fabricated aluminum ribs
Aluminum Leading Edge
Blind Rivet attachment vs. Rib Stitch
|9. What is the fuselage construction?
Welded 4130 Chrome Molly tube
|10. What Engine is recommended
Rotax 503 Dual Carb, with type E Gearbox and 3.0 : 1 ratio.
HKS 700-E (not tested as of 4/1/03)
|11.Why do you warn that it is not aerobatic
Because it is not.
The Micro Mong Ultralight was designed to fall within
Utility Category (which allows spins, steep turns, chandelles and lazy
eights.) at 550 lb gross weight. That is 4.4 Gs+ . By definition,
for normal, utility and commuter categories, the negative load limit is
at least .4 x the positive, or in this case, 1.76 Gs-. Although it is true
the EXP version of the Micro Mong has extra tail brace wires and a Landing
Wire, for the sake of safety and conservatism we have not calculated these
changes to increase load limits. We must however calculate weight. Finished
weights of the MM EXP have varied from 350 to as much as 410 lb empty.
A gross weight increase to 650 allows a 200 lb pilot to operate the MM
easily within Normal category.
Aerobatic category is 6 Gs + and .5 times that, or 3 Gs
To summarize: at 550 gross, we are good to 4.4 Gs+ with
at least a .5 safety factor. At 650 we're OK for 3.72 Gs+ with at least
a .5 safety factor. In reality considering the relative light weight, low
speed, and low inertia, it is not likely one would exceed positive
limits in positive maneuvers. Exceeding negative limits following a botched
maneuver may be another story. Consequently, we continue to recommend Normal
Category maneuvers only.
|12. How is the HKS 4-stroke testing in
the Mong coming along?
Work on three ariframes was resumed following Sun n Fun
2005. As of early June, we are about a week away from priming fuselages.
The immediate goal is to restore our original MM N913RE to flying status
with the HKS installation. Of the other two airframes, one
will constitute a skeletal example for display. The other will be a complete
inventoried kit. Press releases will be issued, probably in late
July, making note about renewed action with this kit that has been in limbo
for the past eight years.
