I am using a brushless Outrunner
motor called a Nippy Black "Uberall" from Hobby Lobby and I have now
switched to a 20C three cell 340ma Kokam Lithium battery pack. The
Nippy Black is a little heavier than some of the cheaper Outrunner motors
but I think it puts out more power for less electricity than the other
motors. It also never over heats. It's heavier main shaft is indestructible and you can
repeatedly fly it at full throttle into a hard surface without bending the
shaft. This motor will literally last you a lifetime.
With the
plane hanging from it's prop most of the time it will give you an 8 to 10
minute run.
I use an
11x4.7 Graupner prop on it.
I use a
magnet motor mount that I perfected over a period of a year or two. I use three
super magnets in a tri-angle arrangement. The magnets are mounted on
popsicle sticks which are crossed in the shape of a "T". I fasten
the motor to the sticks with a small wire tie and CA glue. I also use
some carbon fiber rods to reinforce the sticks. I then make a
matching "T" with 3 more magnets on it and fasten it to the airplane.
The motor pops off very easily and it is better at protecting the prop
than any other system. You can usually smack the prop on a hard
floor 8 to 10 times before it will damage the prop tips.
I use a
Castle Creation 10 amp speed control. I like these speed controls as
they can be programmed on your computer quickly and easily and you can
adjust them for almost an combinations of batteries and motors. They
are also very light weight.
This power
system will give unlimited vertical performance and the IFO flys like a
feather because it's so light. It's about 8oz all up weight
with the battery.
Your IFO will
probably be lighter with this system as I have added a rudder with a third
servo and also a strip foam about 1/8 inch thick 3 inches wide and the
length of the IFO. I put the foam strip both under and over the IFO
so that it has side area. It can't knife edge but it can hover in
the same position that you are in when doing a torque roll. The IFO
doesn't rotate in a torque roll because it has too much wing area.
I leaned how
to do the torque roll with this plane. It's great to practice with
because it doesn't break when you hit the ground. That is if you
don't hit it too hard, other wise you might have to spend a few minutes to
CA it.
If you decide
to order a Nippy Black motor you can get it from
www.hobbylobby.com it is 0808/98
Nippy Black and I paid $62.98 for mine. I own three of them plus a
larger one for my bigger plane. |
