Good question. I don't do IMAC, but Tom does. I've flown a small Yak and small to large Extras and Edges. In all cases the Yak would roll more axially than an Edge or an Extra. Those that have flown this Sukhoi have so far said it flys better than a Yak. This Sukhoi has zero roll coupling with a very small amount of pitch coupling depending on the c/g location. More aft is slightly more coupling. More forward such as in IMAC is less coupling.

From my perspective, which is not IMAC oriented, my obserations so far are that a Yak or Sukhoi are both more precise that the Extra or Edge in any flavor.

IMHO the biggest difference between and Extra 300 (mid wing version, not S or L models) and the new Sukhoi is that the Sukhoi slows down much quicker because of that gaping cowl in front. This makes down line maneuvers easier and makes landing simpler on a short field.

They roll about the same, snap similar, track similar. Some people might not like that the SU slows down so quickly, other will like it.

I am very pleased that you are bringing a Sukhoi to the market and I intend to get one when they become available. The Sukhoi has always been my favorite aerobatic plane and your Sukhoi looks great with the exception of the cowl opening.

The full scale cowls appear to taper down at the front thereby reducing the size of the opening. It looks like your cowl simply rolls in at the front without any taper. The difference is subtle but I think it would look much more refined and aesthetically pleasing.

I think this might reduce the drag a bit as well, especially with a big fat scale spinner out front. I am getting the impression from the flight reports that the cowl may be creating excessive amount of drag creating a "one" speed plane. I like flying a plane that has a little air resistance , it is nice for those downlines, but it is also nice to be able to accelerate and build some speed.

You still have a pretty wide speed range. The Sukhoi just reaches it's "terminal" speed at a lower point than an Edge or Extra. It makes speed management a lot easier in areas where a constant speed is required. If you want to fly faster it most certainly will, but it also performs just about any maneuver at slower speeds if desired.

Tom's will probably fly faster than mine simply because I deliberately blocked the airflow from passing freely through the cowl by installing an "air dam" between the engine box and the rest of the airframe. Tom is using cannisters so he has more free passage of air through the lower half of the cowl and fuselage. That's something I'm going to play around with when I get home.

The wide open cowl also contributes to engine cooling. When you add a big spinner there's still ample room for cooling air.

It's a little like flying a biplane but not as exaggerated. The drag from the cowl is just right IMHO.

An here I was expecting it the Greyhound station any day!

That one has never been seen again to the best of my knowledge. The fastest one to ever be made. In, out, and gone in the blink of an eye.

Oh, that one!

I "forgot" to crate it up for shipping before I left

It appears that I'll be able to get a few flights in in a couple of weeks before I leave again

I'll probably (most certainly?) forget to ship it again

Tom,

Anymore updates on the 100cc Sukhoi, changes, shipping dates, cost, are you taking deposits yet, is the initial covering scheme still available, what header drop do you need, etc. , etc.

thanks, Ward

The only changes are minor things, nothing that will affect flight. Ship date from China is about 11/1, putting them here early December.

Yes we era accepting orders now, we don't take deposits on standard products, just order and allow us to ship when they become available.

Header drop on a DA-100 is 50mm. I do not know what it will be with a single, probably zero I think. I used the KS 86-4 mufflers with rear exhaust, they worked out well. We will have a complete kit for installing cans on a DA-100.

etc. etc.

Thanks for the responses on the differences in flying between the "round" planes and the extras. Tom, it was nice to see you agian up in Sherman. The rain held off and we had a great time (except of cource, for the mid air - it was terrible).

Yeah, it was not pretty. I usually miss the real gory stuff, but in this case I was watching both planes and saw it coming. Nothing I could do but watch it happen.

Dean's been a great help in shaking the 41% Extra down, it's really unfortunate for him.

Back to therapy.

Tom, you mentioned in an earlier post regarding testing this plane with the 3W 80xi. Did you manage the test?
Pat mentioned in an earlier post that a good 80 will do the job, any comments?
Nice looking range of planes Tom.

Cheers.

Euclid,

I'm not going to speak for Tom by any means. What follows is all on me.

In my earlier post where I said that an 80 would fly this plane...I may have been a bit premature. A good strong 80 will fly it, but I think it would take a strong piped 80 to do a lot with it. My personal opinion now is that for any 3D stuff you will need a 100. Now I've been proven wrong before and in this case I
