Funster 20 (oz6456)

About this Plan

Funster 20. Radio control sport model.

Quote: "Some time back, while watching Joe Zdankiewicz's strange and spectacular maneuvers with the RCM Funster 40 (oz6545), Don Dombroski commented, "A .20 size Funster would be nice." Don is pretty slick with his subtle challenges.

The RCM Funster-40 (RCM August 1981, plan #871) is a .60 size airplane with light wing loading and powered with a .40 engine. Now we are considering a .40 size airplane for a .19-25 size engine while knowing that a straight percentage reduction of the 40 will not give us the same desirable performance. We wanted to retain the Funster concept.

As for the Funster concept, there is nothing new, exotic, or unusual involved. We have simply assembled a combination of features that have been proven over the years to achieve the desired flying characteristics. First, we wanted slow flight capability with good inherent stability and it must be a very tolerant and forgiving aircraft. We also wanted reasonably snappy take-off capability and maneuverability when needed, and large wheels on tricycle gear for good ground handling and to facilitate take-offs and landings on grass fields.

The above listed features weren't difficult to put together, There is another asped that we feel is most significant, although purely cosmetic - it must be attractive. Square box type designs are very practical and are already available in many sizes and by the dozen. There are a lot of us who have a lot of pride in our hobby and we enjoy complimentary comments concerning our models from wives, friends, and flying buddies. We feel that this has been achieved wiith very little effort, especially after listening to the compliments at the flying field.

All of this good performance is attributed to a large aircraft with light wing loading and reasonably low power loading. Other factors contributing are a high lift, low drag wing section, large control surfaces, long tail moment arm, and a lifting horizontal stabilizer.

Incidentally, we strongly recommend that you install the flaps if you have a 5 channel radio. They aren't really necessary for the Funster, but you sure can have fun with them..."
