The Great Planes Spectra is basically an electrified
version of their 2-Meter Spirit. That makes the Spectra yet
another one of my Spirit sailplanes.
The 400-size brushed motor that came in my Spectra kit was really a piece of
crap. The commutators would load up with carbon from the brushes so badly after every couple
flights that I had to disassemble and clean them repeatedly. It was a major pain in the rump.
If the Spectra had not met with an unfortunate end, I would have replaced it with a brushless
motor. In fact, I later modified a 2-Meter Spirit to use an E-flite brushless motor and
electronic speed control.
I
decided to try my hand at electric flight and purchased Great Planes Spectra
electric powered sailplane while in Loveland, CO, and was able to fly it from an
expansive field adjacent to my back yard. The only obstacles to avoid were the
cow pies. The Spectra is basically a 2-meter Spirit, with a motor and prop up
front. I think it was a 400 size. Rather than use the servo-actuated on-off
switch, I used an electronic speed control (ESC). The motor was a real piece of
garbage. After about 4 or 5 motors runs, the brushes began fouling with a hard
crust layer after every run. It always involved disassembling the motor and
cleaning the brushes. I got so fed up with it that I just stopped flying it. We
then moved to Kernersville, NC, where we now still live. I dusted off the
Spectra and
flew it a few times at a local elementary school. On one ill-fated flight in the
winter, my aging eyes told me the Spectra was in front of a big oak tree while on
a landing approach, when in actuality, the oak was between my Spectra and me.
Needless to say, I was quite shocked when the beast came to a sudden halt and
tumbled to the ground. The experience was rather strange because the tree was
far enough away that I saw the plane hit before the noise from the crunching of
the branches reached my ears (my eyesight is terrible, but my hearing is still
very good).

The Hitec radio system in my Great Planes Spectra was the only non-Futaba RC
system I have purchased in many years. The receiver had a very annoying feature where it would
crank the servos over way past the normal maximum servo throws if the transmitter was shut off
before shutting off the receiver. Since then, I have bought a Spektrum DX6 spread spectrum radio system, but all others
are Futaba.
Great Planes
still sells the Spectra both as a kit and as an ARF. The ARF is only $30 more than the kit,
which is about the cost of the covering and adhesives - amazing. Those impoverished Chinese
workers sure can turn these things out cheaply. Next time you fly an ARF, thank a Chinaman who
earned half a bowl of rice for his efforts.
