Haha I figured! 👊

About 320 degrees a second to the left, and 300 to the right at 200mph, it snap rolls much faster. The Sukhoi that we’ve just acquired rolls at around 400 degrees a second.

Yes it was. The floor for Advanced is 566' AGL. In a competition I would usually fly to 800' as my lowest point. On this one, I the lowest I got was bang on 800'. The closer to the floor of the box, the better the plane presents due to parallax. Makes the judges job easier.

W76HM148-58 Sensenich wooden fixed pitch propeller, and O-360 with no inverted system.

@@kahaaerosports thanks for your answer. !!! I have another question - How Many RPM and manifol has the plane at 4000 ft agl ? Because mine with ab io 360 A1A engine , at 4000 ft gives 2600 RPM with 21 maniful

Do you think it’s that fine?

@@Fedemizrahi mine doesn't have a manifold gauge, but I'm typically flying acro between 2700-3000rpm. On the downlines I'm pulling the power back so the RPM doesn't go above 3000. If yours has a constant speed prop, I'd try to figure where the prop is most efficient. You can do this by adjusting the prop level and taking note of airspeed in level flight. Higher rpms don't alway mean more efficiency. If you have a fixed pitch prop, I'd be running like I do mine if you're trying to get the most amount of performance out of the airplane without going above 3000. It comes down to the airplane at the end of the day. If you're competing in the airplane, you want as much power/thrust as possible (respecting limits of course) to fly the maneuvers as cleanly as possible. Hope that makes sense.

Thanks for your advise, i’ll keep in touch with you

Haha that's great! Sometimes you gotta do what you gotta do. As long as you know what you're doing, then it can be done.

You're right. There are a handful of youtube videos, and some old documentation. This airplane is very rare. This is the only one in Canada! Maybe one day I'll do a walk around video.

Thanks for the comment. It depends on the loop and the roll type. If I'm flying a competition loop I enter at 160mph, pull 5G and that creates close to a "perfectly" round loop that will score a 9 (keep in mind I don't have inverted fuel so the engine always cuts out under 1g. At the top of the loop, the engine is not running. When I'm just messing around, 145mph @4g works fine although not symmetrical. For the rolls, again because the engine cuts under 1g, if I'm flying a barrel roll, 120mph is fine. If I'm flying a vanilla aileron roll, 120mph will work but you need to keep the nose up quite a bit and need a lot of top rudder in knife edge. For competition standard, I'll fly at minimum 145mph for an aileron roll. 4 point or 8 point, I'll fly 160mph to Vne (180mph). That way I can make the points/hesitations equal with having to pick up the nose with the rudder so the airplane flies along the horizontal plane cleanly. Hope that helps!

@@kahaaerosports that helps a lot. Thanks for the reply.

Yep! The runways run 05 and 23.

All valid points Eric and you're right, the cable should have never broken. I thought about doing a follow up to show the break. Based on the design we saw, it wasn't the greatest of systems so we're exploring better options with some redundancy. We had the airplane inspected by 2 different mechanics over the last 12 months, not to mention our own eyes and hands do some work to. The throttle cable was not inspected by us, but can't speak on behalf of the mechanic. Needless to say, it will be a thorough annual check item for us. Thanks for the comment!

@@kahaaerosports , please do a follow-up video. I would suggest going through the log books to see what, if anything had been done to the throttle system. Check if anything is unique or different from the original design. There should be hard stops at the throttle shaft (engine end) for idle and wide open throttle, and on the throttle quadrant (cockpit end). With most aircraft, the cable system should be adjusted to first land on the throttle shaft idle stop followed by the quadrant stop. For full open, the same, the throttle shaft full open stop followed by the quadrant stop. If the cable system is set in this fashion, there is no way to over stress the cable. Common things that can affect cable system operation include any bellcranks, and bearings. They need close inspection to insure no binding or excess play. Look forward to your findings. Happy flying! 👍

Lots to consider for sure. I was almost certain that the throttle cable would not roll back because I could tell the break was in the sheathing and I could use the throttle rod to butt up against the cable preventing it from moving. I had a friend who have his cable disconnect within the engine bay in his One Design, and the engine went into mechanical idle. This is a great conversation starter about "What Ifs". Something so simple can cause so much potential risk. Thanks for the great comment!

Standard design of throttle systems, if cable becomes free of throttle shaft, the shaft is spring loaded to full open throttle. This is a feature that should be check at every annual inspection.

My pleasure. We can all learn from this!

Haha I'll give one a go although I have no inverted fuel so I'll have to get creative :)

Haha yes, there was one or two :)

80-82mph short final, over the fence at 70mph. Plane was stalled at touch down which is 60mph indicated in this airplane.

They are way underrated for they offer - great airplane. We rebuilt ours in the winter and installed ply wood leading edges that increases the overall strength of the aircraft. It's rated for +6/-3 as per plans, but because ours doesn't have inverted fuel system, I typically fly it to +6G / -1G. Roll rate, I would say 130-150 degrees a sec. Haven't measured it.

@@kahaaerosports That is pretty nice performance. They look so classic as well. I just wrote the company for information. Can't wait to read the literature.

IFR Flight for currency :)

85-90mph works well. 95mph with two up.

@@kahaaerosports Excellent. Hoping to pick one up soon.

@@BellyUpFishGarage They're highly under-rated airplanes. I love ours, and you will too!

@@kahaaerosports Pretty sure your comments on a post I left at "Aerobatic Pilots" on FB helped push me down the path. LOL

Not at all. Only about 1200 feet with 800 remaining. The perspective and high zoom makes it look that way. I was about 5-8mph faster than usual due to the direct crosswind from the left. The dust isn't braking action, I don't use brakes on our strip since the grass slows the airplane down quickly. The dust is just being kicked up by the tires. :)

Haha nothing. I just moved my hand.

Haha
