Hobby King "Minimoa" 2 Meter Foamy Sailplane


(Blogging today because we're experiencing liquid sunshine all day.)

The Minimoa is an exceptionally nice flying 2 meter EP sailplane and I highly recommend it. There are a number of changes from stock equipment that I feel are prudent as noted in the following boring detail.

Folks, the last thing in the world I need is another 2-meter sailplane....

So, why in the world did I buy the HK Minimoa ?? The truth is I was captured by the nostalgia and that cool wing shape. Also, I loved the price at $104 shipped. Actually, I sold the four "quality" (very low ) servos and so my cost was $94 net (I'm a cheap ass jerk, just ask my wife). I read the Minimoa thread and took all the "advice" with a grain of salt. It was obvious to me that replacing the stock motor was a must (as well as replacing the stock "quality" servos).

I thought it would be a piece of cake to remove the motor because of the many posts indicating loose mounting screws. Uh-oh ! Sorry about that old_dude....... they lock-tighted the set screws !!! No way an allen wrench would loosen them...bummer!! So I drilled out those little buggers...but still couldn't pull the motor. I gave the stock spinner and props to a local flyer who needed them (I'm really NOT a jerk honey !!).

Not to be stumped by any china bell motor, (after having ripped the outer shell off) I drilled out the windings and portion of the poles to give access to the motor mount screws...... The motor was then conquered !!... oops I mean removed and tossed in the garbage.

The GP Rimfire 28-30-750 mounting holes fit perfectly in the stock mount.... how very very nice. I did need to use a ball driver to place the socket head mounting screws. I planned on using and older Graupner spinner assy and scimitar prop blades because they weigh 21 grams more than the stock parts. I later discovered that the center part prop hinge points were too close together and wouldn't permit the props to fold completely...another bummer !! Not to worry folks ........ I found just the right parts in my "Hobby Shop" (prop hinge pins need to be => 45mm apart).

More details later...need to go.......

LATER.......... I did program a LOT of aileron differential in........ only 20 percent down going aileron. The maiden flight went very well with no problems at all. A little aileron trim was required and a bit of throttle to elevator will need to be programmed in.

So now I have another nice flying 2 meter sailplane that I won't find enough time to fly regularly ..... too many planes and only ONE pilot.
