2020年11月15日 · The Sterling Yak 9 was a good flyer, it was about 1959 or 60 when all the guys were building 35 size profile models. Frank had a Yak 9, Nick had the Mustang, Keith had a Ringmaster and I had a PDQ Super Clown. We all had either McCoy or Fox 35s.

2023年11月22日 · 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.

2008年8月24日 · The Yak-9 is set up for OTS already. Here is a picture of the same plane set up with a Fox.35 with single LG for sport racing. As you can see, hanging from OTS to racing is simply a matter of changing the LG rom 2 wheels to one, using a "Don's" wheel. the tank also is easily changed from a stunt tank to a racing tank. this is a real fun ...

2013年6月18日 · I'm just getting started on a Sterling Yak-9 and already have a problem with the wing. All of the old kit plywood parts have de-bonded so I'm using fresh ply to re-make them, including the rectangular braces behind the angled LE joint and the center joint of the two spar sticks. My birch ply is much stiffer than the old kit wood.

2025年2月14日 · This laser cut kit is a 52” wingspan 532 square inch version based on the Sterling S3 kit. The airplane is the shape of the S3 kit except for the wing mounted gear and the thicker wing.

2010年2月23日 · HI Eddie! The laser cut ribs, doublers and wing tip pieces got here fine! I am looking forward to finishing that Yak for OTS.

2008年2月15日 · In so far as the Brodak versions of the Yak-9 and the Mustang P-51/F-51 are concerned both are direct copies of the original Sterling Models Kits as issued. There may be misprints of dimensions on their boxes and plans but the final products result in absolutely OTS Legal model airplanes!

The Yak 9 has 85% of the wing area of a Ringmaster, and 81% of the wing area of a Flite Streak. This prompted me to design a YAK 9 RACER. The airplane is NOT for OTS or sport flying. With all the Basswood that the RACER incorporates it is probably as heavy as an original built from an old Sterling kit. The Yak 9 RACER is a laser cut kit with ...

2023年9月9日 · Mine has a 7-4 apc and pulls a lightened Yak-9 trainer with stationary flaps pretty good. MM That sounds disturbingly weak for stunt, I would have expected it to be pretty strong. f it won't even spin 8-4, then it is far too weak, the 15FP has no problem at all with a 9-4 and pulls airplanes like the Yak around with reasonable authority.

2025年3月12日 · I have laser cut ribs for the Sterling Mustang and Yak 9 planes. I believe these are cut the way the plane was originally done and not modernized. Plans can be downloaded off of the Internet. $15 for a set of ribs only. I can bring to the NATS. Otherwise shipping would probably be $5 to $10.
