Colin McRae,
who lives in the San Franciso Bay area, recently built
this Yak-9. He explains the project:
I wanted to build a smaller warbird model and power
it with a our-stroke engine. I ended up
selecting the Yak-9 with an OS .26 Surpass engine. The
Brodak kit is a replica of the original Sterling
model. In order to maintain Old-Time Stunt
eligibility, I used fuselage-mounted landing gear and
did not upgrade to wing-mounted gear and adding wing
dihedral.
The four-stroke engine uses the stock OS carburetor
and is set up with a manual throttle adjustment system
where I can start the engine at 1/3 throttle for a
brief warm up, then set to full speed for the takeoff
and flight.
