Michael in Toronto,

Your Cub is first rate! I would assume you have a very large indoor space in which to fly it -- no basketball court with messy baskets hanging down to hang your Cub up

As soon as I saw the start of this thread, I thought of a similar project by Tony Naccarato, in California, in the 1980s. He built and flew indoors a 6-foot span Farman Moustique. Power came from NiCads, of course, and the propeller was spun by an Astro Flight 05 cobalt brushed motor, geared (2.5:1?), the motor of choice in those days. Construction was balsa and heat-shrink film. I assume the color was red, per the prototype Moustique.

I remember seeing that it a magazine back then.

At about 20 to 21 ounces, I think my plane will fly in a gym, but I will test it outdoors first to trim it, and later in a golf-dome, where I will practice doing a slow and tight oval pattern. Next autumn I will try in a gym.

Another photo showing strut detail. Struts can fold flat for transport.

Well done Michael,

Now ignore all the folks out here yelling for you to fly it...(including me! )

Be patient and wait for that idyllic evening. A fantastic job deserving of extraordinary conditions.

Maiden flight photos.

Wind was about 5 to 10kph (3 to 6 mph) which is probably the most this plane can handle. Takeoff roll was slow, but wasn't much more than about 2 feet long. Power was marginal in the wind; forward ground speed into the wind was about walking speed. Downwind speed was still visibly slow. The model could turn in about a 15 - 20 foot radius. One of my scratch-built wheels came off on landing; the stryrofoam around the carbon fiber hub is not strong enough. I might need commercial light-weight wheels.

Looks great.
A bit of 1/64 ply would re-enforce the wheels and spread out the load.

Does this mean the field is now open

The field and pits area are relatively dry.

The parking area is wet mud and deep water; don't drive past the rocky roadway, but go flying if you want.

Before you switch to heavy commercial wheels, try making some from EPP. It's way stronger and tougher than Styrofoam and shouldn't give you any kind of trouble. The only drawback is that sometimes the wheels will develop flat spots when parked for a long time; you can get around this by hanging the plane or by building some wire stands to support the axles and keep the wheels off the ground when the plane is in storage.

I saw some light wheels made from a swim noodle once. I'll bet that would work great for these. Cut a lightweight hub from balsa, cut and shape a tire and glue it to the hub. You'll be all set.
