This is another plane made for the dome, but can also be used outdoors as a parkflyer plane. I saw a thread on RC Groups that gave plans
, but was for a smaller size version. I wanted to use heavier sp400 gear, so I enlarged it to around 400 in/sq and it flew very light at this size. I built it from blucore foam available from Lowes, and the size worked out well allowing two planes to be built from each 24″ x 48″ sheet. The carbon rod around the nose worked well for preventing prop and motor damage during crashes.I used black zagi tape to color the canopy
and make two orientation stripes.
Flying the Yuk-54 was quite fun. It operated with simple elevon radio mixing plus rudder control. Hovering was nearly hands off, and flying nose high high alpha manuvers was easy as well. The only thing it didnít do well was knife edge flight where it wants to roll out when you use the rudder. This plane flew very well with 7 ozís of motor/esc/and battery. I may give it another try with modern brushless motor and smaller battery as it could probally shed nearly 5 oz of weight.
This was a fun and very inexpensive plane, a good parkflyer, and makes a decent 3d trainer as well.
