2026-2027 Ministick Online Indoor Postal Contest

What is an online Postal Contest? It is a contest where everyone around the world gets to build a Ministick, go fly it, then submit their scores by email to see how their flights compares to other modelers.

What are the rules?  Ministick is an offical AMA event (#220) and the rules are in the current AMA rulebook. To save you the effort I have refomateed the rules and they are below.


Mini-Stick. For Event 220.

1. The Mini-Stick model shall be a monoplane covered with any commercially available material sold in sheet form. Microfilm is not allowed.   

2. The maximum projected wingspan shall be seven (7) inches.

3. The maximum wing chord shall be two and one-half (21/2) inches.

4. The maximum length (from front of nose bearing to front of rear motor hook) shall be five (5) inches.

5. The maximum length from front of nose bearing to rear most part of model shall be ten (10) inches.

6. The projected area of the stabilizer shall not exceed 50% of the projected area of the wing.

7. The maximum diameter of the propeller shall be seven (7) inches. The propeller shall be constructed of wood. Wire shafts are permitted. Hubs that allow blade replacement and/or manual pitch adjustment are allowed. Mechanisms that cause variable pitch and/or variable diameter of propellers while in flight shall not be allowed. (Natural flexing and flaring of wooden blades is allowed.)   

8. The minimum overall weight of the model (without motor) shall be 0.015 ounce.

9. Construction is to be primarily wood, with adhesives used only for joining. Tissue and/or thread is permitted for wrapping bearings, hooks, and for making sockets, if desired. Boron, carbon fiber, Kevlar, and fine
wire bracing are not permitted.   

10. Mechanisms that restrict the torque available to the propeller are not allowed.



How do I enter my flight times into the Postal Contest? To enter your flight times, send an email to don@indoorfreeflight.com
Your postal entry must include the following items:
1. Your Name
2. Flight time in minutes and seconds (e.g. 1:17 = one minute and seventeen seconds)
3. Date of your flight
4. Ceiling height of the building you are flying in (e.g. 24ft 5inches) FAI ceiling measurment should be used, that is ceiling height measured at a 50ft diameter circle.
5. Age classification: There will be two age categories, "Junior Class" and "Open Class"
    if the contestant is 15 years old or younger then please note they are in "Junior Class"
    if no age classification is included in the entry then it will be assumed they are in the "Open Class"

You may enter as many times as you like. As your flight time increases, send in your new scores. Fly in a new venue, send in the score. All flights must be submitted by the end of the day on May 31th, 2027

Why are you requiring the ceiling height where I fly?
The ceiling height will have an effect on how long the model can fly. A higher ceiling generally means longer flight time can be achieved. Knowing the ceiling height can help me graph the flight time based on ceiling height to try and come up with an appropriate correction factor. This is a method I used years ago when I use to run online postals.

Winners will be announced the first week of June 2027.
