Brodak Yak-9 Build

(1/9) > >>

Colin McRae:
I have been wanting to build a 'smallish' warbird model and use a four-stroke engine. So, I decided on a Brodak Yak-9 kit that will be powered with an OS 26 FS. The Brodak Yak-9 also qualifies for OTS since it is a replica of the original Sterling kit design.

I was hoping to get some great 'lessons-learned' guidance from builders that have build-experience with this particular model. I am somewhat of a rookie builder, so I am open to all suggestions and recommendations.

The only thing I am not going to change is my OS 26 Surpass FS engine choice. I really want to do a CL warbird w/ a FS engine. Absolutely love that FS sound.

Thanks in advance.

You may want to look into getting the dihedral and wing mount landing gear kit for the Yak-9 through Brodak.

It raises the leadouts to get the vertical CG closer to where it needs to be, which will give better handling.

Between the Yak-9 and F-51, the Yak flies better, so good choice.

Thanks Steve, I would love to do the conversion, but our club somewhat bumpy CL circle is not particularly friendly to wing-mounted landing gear. So, I will use aluminum profile-mount gear. Not the kit-provided wire gear.

You can still use the dihedral part of the kit to adjust the vertical CG, and use the aluminum gear.

The Yak-9 was my slow combat plane during a year of friendly warfare while stationed in Korea.  My counterpart, one of the Wolf Pack pilots flew the Mustang.  McCoy 35's at high noon!  We had quite a spectator audience for the duels.  The Yak outperforms the Mustang but "it's the pilot, not the plane" so I only won my share.  I concur with the dihedral, it needs it for stunt.  Good thing the BX kept both in stock.  They didn't last long!
