Hello guys and gals I recieved my Sea Hurricane in the mail today; thanks very much. I thought you might like to see the Yak-9 that I just completed.

YEAH!! Yak 9s forever! I still have the one I built in 1994 & it is still flying (just to keep Keith Trostle on his toes.) Mine is very high-tech with an L&J Fox .35 & a beat-up original Y&O 10-6 prop...well, maybe not so high-tech but fun anyway. The Yak is a replica of the one I built & flew when I was in high school and I just had to have another one.

Yup Bill my first Yak-9 build was 48yrs ago. n~

That is a great looking Yak-9. Is that from a Sterling kit or another manufacturer? I started C/L in1953, but didn't get to build a Yak until 1987. I fly the Yak with Foxes, .35 stunt, .29 stunt and .25 stunt engines. In 1987, I found a hobby shop going out of business and there were 6 Sterling Yak-9 kits on the shelf. Knowing that Sterling was also closing up shop and the Yak-9 was going to be a classic kit in the future, I bought them all. So far, I have only built one , but I have started a second one. I don't know if I will get them all built before the call to the great circle in the sky, but, the Yak-9 is one of my favorite sport planes. H^^

When I built my current Yak 9 in 1994 I used the original Sterling kit for patterns and supplied my own wood. The wood in my Sterling kit is just too heavy; for example, the kit fuselage blank as it came in the kit weighs right at 6 ounces. The fuselage that I made ended up weighing 3 1/2 ounces including motor mounts, doublers, scoop & canopy. I cut the middle out of the blank up to under the canopy, added a balsa stick truss in the cutout area, and sheeted the sides with 1/16" balsa with carbon fiber strips (.007"x1/4" wide) under the sheeting at the top & bottom. The rest of the kit wood was replaced also as it was equally as heavy. The finished airplane weighs 25 ounces with a metal tank & Fox .35, which is not super lightweight but a lot lighter than if I had used the kit wood. The finished fuselage is quite stiff torsionally and has flown all these years without any structural problems. The main problem my Yak 9 has had is that about two years after I finished it guys started building much better flying OTS airplanes so my brief run of OTS trophies came to an end.

I had one Sterling Yak 9 that I did with the flaps. Leaned the engine out and fly. Did not know about it being overweight or bad wood because it would do all the loops, eights and inverted I wanted to do. I let some kid have it later in life that was getting into CL. #^ #^ H^^

Thanks for the kind words about the Yak-9 guys. It was a Brodak kit and the wing is a lot differant constrution than the old Sterling kits with better wood than Sterling also. Just the same I still remember having a really good time with those Sterling kits back in the early 60's. Tight lines to you.

Someone needs to come out with a kit like one of the first I had. All printed wood. Instructions say cut out side the line and then sand to fit. Die crunchong put us in seventh heaven. H^^
