| Coaxial | The
most inherently stable type helicopter. 2 counter rotating blades
generally are driven by 2 seperate brushed motors. These helicopters
can not move laterally (side to side) very fast so are very susseptable
to wind dragging them off. When learning on a coaxial you are mostly
learning the left stick which changes rotor RPM to climb/drop as well
as yaw (rotate) the helicopter. Some people swear by starting
with an indoor coaxial (if you have the room) while
others will say
they were quickly boared with it. If you have the room for it, starting
with a coaxial will nearly never be "too much" of a helicopter for any
teen or adult. If so, then you would want to rethink finding another
hobby. Having an indoor coaxial in the winter months for the
northern climates can come in handy to get your "heli fix"
in the
winter months if a simulator does not do it for you. These helicopters
might come as "bind and fly" (Require you to have a compatible radio)
or RTF (Ready to fly including battery and Radio). Generally, many
mishaps/crashes will result in zero damage if you drop the throttle at
or just before the moment of impact. Coaxials

| Fixed Pitch | A fixed Pitch heli has a fixed pitch set of rotor blades and a Brushed or Brushless motor to drive it. It will have a motorized tail blade typically that is driven by a 2nd motor. Fixed pitch helis are typically a stepping stone to CP helis. Many people later come back to enjoy their FP heli to become a park or backyard flyer when there is little or no wind. Fixed pitch Helis hover more like a conventional CP heli and allow slightly faster forward flight. They are cheaper to repair because typically, less things break in a crash. Generally, many mishaps/crashes will result in zero damage if you drop the throttle at or just before the moment of impact. 2 types of FP are emerging. Flybar with paddle (Esky Honey Bee FP, Falcon 40). Flybar with weights and no paddle (Walkera CB180, Exceed Madhawk 300) The CB100/MH 300 although more stable than a HB FP, they have less forward/lateral speed so they should be flown outdoors on only the calmest times (<3mph) unless you modify the linkages to allow for more forward/lateral speed. |
| Collective Pitch | The Collective Pitch Helicopter has a motor which drives the rotor RPM but the pitch of the blades vary with stick movement. The left hand veritical stick controls both in tandum and is mixed electronically in the radio. Ultimately, this is where you will end up if you continue to persue the hobby. CP helis come in various sizes from tiny Micro palm sized helicopters to larger .90 nitro helicopters. The most popular size to learn on if you decide to go CP is the 450 size. Originally named for the size of motors used, these helicopters use 315-335mm blades (325mm is typical). In general, bigger is more stable, faster, more expensive to buy and fix as well as more dangerous for the novice pilot. If you think you might want to start out on a helicopter larger than a 450 sized helicopter, you most definitly seek out multiple sources of personal advice stating why you want to and listen to opinions before doing so. Lots of people have skipped over the Coax or FP heli to learn on a CP. There are also those that started on a CP, were frustrated, then stepped back to a FP or Coax. Generally, many crashes on a CP heli result in multiple items being replaced which requires both more time and more $$ to repair as well as knowlege. Example of a 450 crash part list. Many of the 450 sized helis that people are learning on can be upgraded to better motors,servos, gyros, blades ETC as the hobbyist progresses to where those upgrades will realize more benifits.
