This seems like a very good deal. I called and asked who makes this ARF, and they said it's a Cermark. I don't find this plane on Cermark's webpage though. Please respond with any information anybody might have on this plane. I am concidering mounting one of my YS91AC engines in it.

Well my daddy always said . If it seems to good to be true it usually is

Did you try to checkout just to find no checkout button?

I'd be willing to try this bird if they would just let me buy it. If it was a lemon, I would not hesitate to post my findings here!

I bought this, and intend to post my findings here.

So far, I am displeased the wing is foam, but not sheeted. I guess it could be sheeted, but with additional weight. All edges of the wing covering are lined with tape striping, which is kinda chezzy, but the rest of the model looks good. They used plenty of glue on the wood fuse. And the firewall is really thick!

I know this plane. It is not new to the market, and yes, Cermark was (is?) the original distributor. This Sukhoi is very, very, very twitchy, and requires about 25% more engine that that which is recommended. DO NOT slow this plane down too much, it stalls fast and mean.

Aside from the above, it builds well, flys well, is extremely manuverable, and is fun to fly for the EXPERIENCED RC pilot.
E Caveat Emptor (let the buyer beware).

So slow flight is out of the question? And so is 3D, short of hovering I suppose? Would a YS91 be enough, or would it need a YS120? It's starting to sound like an aerobatic plane with high wing loading for its size? Are figure 9s as supposed to loops common unless completely throtteling down on down line? I don't want to even waste the $120 if this plane basically needs to be flown like a warbird he he, rather get a warbird and go for speed then.

7.5 lbs is heavy, and I'm guessing it would be even worse with the 91.

Slow flight is indeed possible. Remember that most of your 3D manuvers are performed at high power settings using the prop that best provides thrust, not speed. The same 3D manuvers are performed at much higher than normal angles of attack.

In this case, power and radio mix set up will be everything. Look for an engine that provides as much power as possible at the lowest possible weight. I'm not generally in favor of two strokes for high alpha flight, but most of the 4 strokes that will provide the power you will want will be too heavy. Lighter IS better! A really strong 60 to 75 will do fine.

Keep your props in the 12x4 to 13 1/2x 5 pitch range. Try to keep your fuel tank size at 12 ounces or less. You won't have as much flight time as you might like (about 8-10 minutes), but your plane will be lighter. Don't use higher than 15% nitro fuel in the attempt to find more power. Unless you are running a tuned pipe (more weight), all you will do is wear your engine out sooner. I think you will be happy with this set up.

Good Luck!

If this is the plane I think it is, I can tell you without hesitation it gives new meaning to the word POOCH. Its heavy for its size, my friends came in at about 8.5 lbs with a 91 2-stroke. It was really hard to slow fly or high alpa fly. It did great snaps whether you wanted them or not. Even with the CG at about 25% MAC it was still poor at best. It might be the reason Cermark dropped it after only one season.

I have two of these planes and a friend has two also. The reason that I have two and that my friend has two is that they are a blast to fly!!! My friend and I both have OS .91FX's on ours and they have plenty of power. The planes have a bad rep. But I have found that if you start out with small amounts of elevator they fly great. If you use a lot of elevator, like 100% they will snap like a scalded dog!! We use low rate at 35% and high rate at 85%. Stalls are gentle and straight ahead. On high rates the thing will tumble like crazy.
With a APC 13X9 they are a bullet and hard to slow down when it's time to land. A APC 15X6 gives you a lot of thrust but is to slow getting the rev's up. We have settled for a 14X6, good thrust with good engine response. They are also one of the best ground handling airplanes I have ever flown. They are not for beginners, They are a little Quick!!!!!

P.S. With a little paint they also look great.
