Each year the Spirits' host a changing wide range of events to allow pilots to demonstrate their skill and show off what project they are working on.  Each event has its own flavor catered to different aircraft, flying styles, and activities. If you can't find an event at Spirits that interests you, you are probably not interested in RC flying.  Our events are always run by Spirits' Members that are responsible for the organization and execution of the event.  Volunteers, club members and spouses, provide support for concessions, parking, pilot registration, raffles, etc.  Events usually occur on Saturday mornings, some events are free for pilots, some have a small landing fee, check the event schedule below for dates and times.  All pilots participating must present a current AMA card to fly.  A contest, by definition, implies competition.  An event is non-competitive.  A Fun-fly is competitive.  A Fly-In is non-competitive.

Spectators Always Welcome!

Spirits' always welcome spectators with open arms.  Our field is like having your own private park with an airshow happening in the middle.  There is never any charge for spectators.  Bring a lawn chair and stay for the day, with mature shade trees and a pavilion with ceiling fans you can beat the summer heat.  Concessions are usually available during contests/events, and a restroom facility is available on site.

If you want to check out some of the aircraft, ask any of our pilot members, I'm sure they will be happy to talk with you and show you their aircraft.

You don't have to wait for an event...If the weather is nice there is usually someone at the field.  Feel free to drop in on us anytime.  The field is open from 9 AM till dusk every day.  Click the Directions link in the blue bar above for directions to the field, or use your GPS. The Spirits flying field is located at 73 Amrein Road, St. Charles, MO 63303 Lat. 38.702006, Long. -90.577898

A minimum ready to fly weight of 4-3/4 pounds, without fuel is required. The ARF Four-Star 40’s are legal including the wheel pants. The Sig kit version and Value Hobby Stylus 60 may have the outer bay of each wing cut off, and the canopy recut to a lower profile like the Four-Star 54 EG.

All pilots must have a current AMA card and register to fly.


Unlimited Electric Warbirds:

An unlimited class of electric powered propeller driven aircraft from any country modeled after propeller driven aircraft flown during WWII; or WWII aircraft which were later raced at Reno Unlimited Air Races. Electric Warbirds may be hand launched. Fast furious fun in only 7 laps!

High Wing Trainer Races:


In an effort effort to increase participation in racing, a class of racing was conceived that anyone can participate in.  Spirit of the rules:  Fly 10 laps with a stock unmodified commercially available high wing trainer with engine or electric motor size, ESC, and battery recommended by the manufacturer.  No Tuned Pipes, or Tuned Mufflers.

All pilots must have a current AMA card and register to fly.

Helicopter Fly-In


The Spirits' host a helicopter fly-in each year.  This event is open to all current Spirits and AMA members.  A day of fun flying and watching all types of rotorcraft from all around.  Helicopter clubs from across the Midwest come in to have a great time, share some stories, and look at all of the different flying machines.  Spectators are always welcome and you will not be disappointed.  From tri-copters to quadcopters, scale to stock, you do not want to miss some of the finest stick-banging 3D, autorotation demos, and sport flying in the area.  For this event 6 pilot stations are set along the runway and the helipad is open for hover practice.

Landing Fee $10, includes lunch.  All pilots must have a current AMA card and register to fly.

Tuesday Night Warbirds

Throughout the spring, summer, and fall those wonderful Warbird flying machines take to the air and turn quiet electrics and nitro noise, into smiles, glimpses of the past, happiness and sometimes sadness.  Getting together in the late afternoon and early evening at the Spirits Field to share stories, show off their aircraft and enjoy flying their Warbirds is the goal.  Any type of Warbird or Warbird looking airplane whether nitro, electric, glider, helicopter, etc. is always welcome!

Of course electric aircraft are always welcome anytime at Spirits.  The tradition of Tuesday Night Electrics started as a time and place where pilots interested in electric aircraft could get together, learn from each other, and watch other electric aircraft fly.  Nowadays electric aircraft are almost as common as nitro and gas aircraft.

If you have an electric plane or helicopter and want to talk to the electron wizards, come to Tuesday Night Warbirds.

This is a club based event open to all current Spirits' Members and guests

The event that has a positive impact on our hobby is Scout Day.  During this event we invite local Cub and Boy Scout units to join us at the field for a day of flying fun and education.

Our staff of volunteer instructors take the boys through ground school teaching basic aeronautics and the nomenclature of many aircraft components and their operation.  A basic discussion of aerodynamics and how flight controls work is also presented.

Finally the boys get a chance to fly a model aircraft under the guidance of one of our instructors.

If your Cub or Boy Scout unit is interested...contact us to see when you could schedule your own.

All Scouts that fly are required to have an AMA Form 2 signed by a parent and turned in to a Spirits' Instructor prior to flying.
