Status: offline 		I flew 6 tanks of fuel through the new Sukhoi today. It's a really nice flying plane. Most flights were for trimming and getting used to the plane. The best way for me to describe the Sukhoi is to compare it to the other WH 28% planes. First off, the plane has no bad habits. There were no unexpected snap outs at tight low rate loops. The plane tracks like it's on rails. Much better than the Edge. The rudder has mondo power. The plane looks great in the air. Knife edge needs just a tiny bit of aileron added to hold the plane vertical. It's really neutral in knife compared to the Edge and Extra. That can easily be mixed if desired. The huge opening in the front limits top speed and really slows the plane on downlines. Constant speed is much easier to maintain than the Edge and Extra. Upright and inverted flatspins are slow and simple as can be. Harriers and elevators are super stable and as done as well if not better than the new Extra.

Landing is a bit different than the other planes. This may change with a balance change. It's not harder, it's just different. I'm thinking it may be the big cowl opening. The plane doesn't seem to float down the runway like the other 28%s. Many will like this. As speed bleeds off on approach, the plane settles faster. Instead of floating in to land, I started to carry a couple clicks of throttle on approach pulling to a slow idle of about 1650rpm right before touch-down. After the change, I greased every landing.

I didn't wring the plane out or haven't done 3-d down low yet. But, I can see the plane will do everthing as well if not better than the new version 28%s.

The new 3MM/TOC started easily, and pulled great all day. It's still a bit rich but it turns the MSC 22x8 6870 rpm. I think it'll turn 7000 rpm after the final adjust.

These are just the first impressions of the plane. As I get more time on the plane, sticks, and engine things will get better yet. I'll start to work the set-up harder this week. I'll keep you posted on my findings.

What are the current deflections and balance point your using?

Status: offline 		The Prototype flys almost identical from the flight reports I have read on the Sukhoi. Landings are as you mentioned extremely easy with the slightest touch of throttle, the big cowl slows her down nicely.
I have the Yak almost finished with a canister, I previously had a pitts wraparound but wanted to try the tunnel out. Now if the weather will cooperate I will get a chance to fly it... Should be fun with the additional power (I have a MVVS 45 mounted on the nose, which flew it very well previously)..

Status: offline 		On low rates I have 12.5 degrees of deflection up and down on the elevators. Even on low rates, it does extemely tight loops/rolls. The elevators on high rates have 47 degrees up, and 50 degrees down. The gap between the stabs and elevators is only a few thousandths of an inch, and 60 degrees of deflection is obtainable. I have full rudder deflection on low and high rate. Ailerons are set with 20 degrees on low rates and 35 degrees on high.

As I fly the plane more, I may change the set-up. For now, this is what I'll use.

Status: offline 		Oh, the first few flights were flown with the balance right on the center of the wing tube. The plane was very stable there. I ended up moving the flight battery pack towards the back 12". I haven't rechecked the balance point, but it doesn't seem too tail-heavy.

Status: offline 		Sound great marzo, I'm also working on one and hope to have it up pretty soon. Hearing good field reports gets the blood pumping. I even brought my stabs to work last night to glue in the robarts. And your right, Mucho deflection even with a tight gap in the surface. I have a BME 50 on mine with a menz 22x8 prop. That big cowl sure does dwarf the size of that prop.

In shipping 3 parts of the cowl ring had came apart, I had to realighn and reglue the sections back in. I used gorilla glue which expanded and filled in any cracks. Know that cowl ring is as strong as an ox. I love the fact that gorilla glue is so strong yet so light and easy to manage. The newer sukhois with the one piece rings should really be a plus.
I'm hoping for a true 3D/ IMAC neutral flying plane. The numbers say yes so we will see.

Thank you very much for the flight reports. (Drooling) Come on, container!!

SAL98,

I'll write a note to your employer and ask if they'll let you bring the whole plane to work

I cant wait. The new club I joined is a little tight for my 35%, I am hoping that this one will hit the spot.

Status: offline 		Mine arrived on friday 1 June 07. Nothing to do but wait for the hardware package to arrive. The plane arrived in perfect shape, don't even have one wrinkle in the covering. I hope the package shows up this coming week, Tom has sent it.

Status: offline 		I enjoyed seeing Wil Curtis display the full size Suhkoi GSIID at Biggin Hill today. Brilliant - torque rolls, hovering, cartwheel. harrier and more. It certainly made me want a Bunny version all the more. BTW it no longer carries the HONDA graphics. If I get it right there should be 2 photos.
For those of you who don't know, Biggin Hill was probably the most famous of all the RAF airfields during the Battle of Britain and to watch a Spitfire being flown there was quite emotional.

Status: offline 		Where's the best place to put the rudder servo? I'll be installing the 3M 53cc motor. In front in the provided hole, or in the back of the fuselage?
