Here we go again with the SkyFlight Sukhoi SU-47.

Much respect for hand launching this bad boy. 👍 I have one myself but it's still in the box for the moment.

[@garyflint1965]

Many thanks for your comment. Good luck for when you get round to assembling and maidening yours.

[@nicksrc908]

I bought the kit version a few months back. I'm going to set it up like yours. I want to keep it plane and simple. I bet it would rip on two 4s packs.

[@garyflint1965]

I found nice and simple is best with this aircraft. I'm running the standard power system but more power wouldn't go amiss...good luck with your build.

[@renerosentraeger]

Nice to see it in action again 😊👍👍

[@angelreading5098]

Well done Gary,a tricky little beast.

[@garyflint1965]

Thanks Barry, yes I think I've got the better of her now.

[@Derangedforsure]

I just started building mine, not a big fan of the split half construction. I am also setting it up as a belly lander, no gear saves a ton of weight. Good flying, I was expecting a stall at the end but she just flopped, beautiful.

[@garyflint1965]

Not installing the gear is the right way to go, as the power system that comes with it is just not good enough. If you are using stock servos I would change them for something more reliable, a couple mine have had glitches. She will stall in a slow turn so be sure to have some speed on in the turns, landing as you see isn't an issue. Good luck with your build, if you need any assistance get back in touch.

[@Derangedforsure]

Gary Flint That’s why I purchased the kit to add all my own electronics. Also, how do you have your control surfaces set up,? (mixed or standard).

[@garyflint1965]

@@Derangedforsure Sorry John just seen this. I have my control surfaces set up as standard, just keeps things simple.

[@chriswalby7934]

Hi Gary, thanks for the vid & info, where did you end up with the C of G as I have one. Using Speky Safe helps hand launch with mine + no thrust vectoring. Mine pitches up if the THR is chopped, IMO to do with the cheat holes and thrust tube angle.

[@garyflint1965]

Hi Chris, my c of g is exactly to the manual so 20mm back from where the main wing intersects the fuselage. I have to wait for a descent headwind before flying mine, this makes the hand launch easy. I find that most edf jets with a large wing area pitch up when the throttle is chopped, they do settle after a couple of seconds though.

[@chriswalby7934]

@@garyflint1965 Thanks for the info and I think I'll strip the unwanted TV servos out to lose as much weight as possible. See if I can get to the 2250 after the carbon in the wing install.

[@rcpowres]

Interesting. Very pitch sensitive. Did you also try to use a flight mode which inhibits the canards? I wonder if that calms down the yumpy behavior in the pitch axis during normal flight.

[@garyflint1965]

Sorry for late response. It was the C of G that was causing the sensitive pitching, now using 6s batteries in the right position and it is perfect.

[@rcpowres]

Ah ok. The cg on my su seem to be ok. But I think my throws of the elevator and the canards don’t match. Can you provide us the angles you set up on your berkut? Grüße from Berlin Chris

[@garyflint1965]

If you pause the video at the right place on the second flight you should be able to see the canard and elevator angles, I haven't changed them from that flight. I will check it for you next time I run it up.

[@evildragon1774]

Do you built it with stabilizer in there?

[@garyflint1965]

Sorry for late late response, no stabilizer or gyro installed.

[@владимирбукреев-ы2г]

Спасибо

[@garyflint1965]

без проблем

[@AzlanRich]

Aircraft fantastic ! But the cameraman is very poor recording the video. You don't know how to zoom & focus to the object.

[@garyflint1965]

Unfortunately the camera has a fixed lens so no focus or zoom.
