Mike,
Thanks for the positive comment. The "Hobo" has many options, including internal or external pushrods. They have been built both ways. I personally like the external set up since you can easily play with flap to elevator ratios, and fine adjustment of the pushrod lengths. Bill Hummel uses 1 to 1 flap to elevator. I use a little less flap movement. The "Hobo" is good for Sport, Intermediate or Advanced stunt. There has been nothing new for these purposes available in over 20 years, and certainly never an airplane with all these options.
Phil,
The simple old fashion box fuselage was done for simplicity and fast building. The secondary goal was to have an appealing looking airplane. The major difference from the older designs is that everything about the aerodynamics is new.
