Jan, i am itching for a flight after seeing that!
I am almost there! I could fly with a single 2200 4s but it would be short. So, I will fine tune: Thanks Vicentel for the help!

I am a relatively new pilot, and getting a little old for this I think (64), so I am not sure I can handle such a fast plane.

By the way - good luck with your maiden!!

Still 59 minutes remaining video upload...

Hi Jan, Very nice plane, well done. Now you must make one for yourself.
Never too old to fly it. Build it and you will fly it. She flies like a glider if you reduce the power and moves like a rocket when you give it power.

I am itching to get my 2 year old Su back out now that it is less than 100 degrees in Airzona. Batteries get just a bit too warm in the summer out here.

Here is the post with some slow speed and high speed flying.

John,,, like your landing gear and how your plane performed.. about all of my damage comes from hand launches, I've been thinking along time about gear, but will venture along with retracts before long! Nice plane! w.

You're very welcome indeed. I am glad to help any way I can. I'm just so jazzed that someone else besides me is doing this. Just for grins I tried the jet with a 3s 2700mAh 30C pack to see what kind of power I could get. The system still draws 66amps, which the battery has no problem of supplying, but the amount of thrust is less than 52oz. However, I think it will still fly but you would probably be at full throttle all the time. I want to catapult launch this plane but I'm too afraid to.

I cringe every time someone mentions catapult! I visited the local flying field and it was like a 3 stooges skit- 3 guys trying to catapult a flying wing! Needless to say, it never went airborne and finally the motor mount let loose and they walked away swearing about it! I will add a throw handle on the bottom. I mentioned it before, but the JMW Tornado has one that makes launching easy. I added carbon rods across the nacelles for support and will put a depron handle across it at cg point. It allows an overhead launch with plenty of force.

Hi Walt, I agree with the hand launch being hazardous to the planes health..Ha Ha. I have done my share of "hand launch crashes"..My best was a 96" sailplane which I demolished due to too much motor torque and a somewhat less than level launch...Live and learn...It's all fun.

LG is great from asphalt but the weight is a consideration, my Su 37 is just a bit portly with all that paint and the added gear but she flies great. I just keep a couple of sets of props on hand.

One thing I added to help prevent banging the props was two fins on the underside of the "engine exhausts" that are long enough to scrape first and usually protect the props..Kinda like training skids...LOL

Cheers to all that build and this fine plane,
John

John,
Nice video from your flying the SU, always interesting to see new places! I remember your plane from last winter when reading this forum and building the Sukhoi (and sanding!!). Please post video when you go fly again.

I just finished my second Polaris, and I am about to repair my first one. I would like to build another SU37, but for now I am happy with what I got. Too many projects and too little time! My nephew and I also built each our Quadrocopter last spring, lots of fiddeling with electronics and programming - interesting but time consuming. And first of all I like to go out and fly when weather is nice - not too often around here at this time of year...

/Jan

I love my bungee setup, but I admit it is a pain to drag out every time. I built it a week after my first prop strike when launching one of my larger pushers... 9 stitches and a bloody car ride home convinced me it was a good idea

This plane is a work of art as well as a plane and i am on week 3! Will balance edf blades and... Sand some more until batteries arrive. It will be a very special day when it finally flies!
