Yellow 13 Mission 2: Su-37 Super Flanker (3 min 44 sec)

Posted by T3chDad | Sep 04, 2008 @ 02:39 PM | 10,828 Views
Iím a big fan of the Ace Combat series of video games. Iím a big fan of the Flanker series of fighter jets. This is the result of the union of both.

This is a 28Ē wingspan version of the Su-37 Super Flanker designed by Steve Shumate. Before I even started this build, I had it in my mind to do the paint scheme of Yellow 13, youíre arch nemesis, from Ace Combat 4. After about 50-60 hours, I had a finished aircraft and I think she turned out great. Iím still amazed that I was able to do this from scratch out of two sheets of Depron.

This video was shot yesterday over the course of two flights with two cameras (thanks to Jeff and David). I edited this video together to be like a mission from Ace Combat. At almost four minutes long, this video is a little long for me, but I hope it holds your attention and keeps you entertained. The music is edited from three different tracks on the Ace Combat 5 soundtrack using Audacity. All the graphics were created in Paint Shop Pro 11. The video was created with Windows Movie Maker 6.0.

In my last blog entry, I stated: "Next week: loops and rolls..." Well, here ya' go. They're not clean, and I'm still a n00bie, but now I'm having a lot of fun at it!

This time I'm flying my BeltCP.

I have been flying helicopters (or trying to) since mid-September. With helicopter piloting, I had always read that one day it will just "click". I thought I had somewhat of an idea what they meant...boy, I was wrong!

It happened to me on New Year's Eve. I had no idea how profound this "click" would be. All of a sudden, I was at ease (not a tense ball of nerves as usual) while I was in the air. I wasn't afraid of crashing or losing orientation. I tried a bunch of stuff I had never done before and the funny thing was that I never left my comfort zone. I was banking and yanking, FFF, pirouetting, piro turns, tail-in, tail-out, collective punches, and various simple combinations of them...and it all felt extremely natural and smooth. I'm now flying in Idle-Up mode 100% of the time. It's slightly different than normal, but I've got the hang of it....now just to re-program my thumbs to hit a switch instead of dropping the stick after setting down.

I can't believe what a difference it was.

Thank you to everyone that has helped me here at RCGroups.

Next week: Loops and rolls...

Look what Santa left under the tree for me!

The maiden was yesterday. After six flights, I've got her all tweaked and flying great. This is one smooth, quiet, and stable helicopter! I've been flying a BeltCP since September and I didn't think there would be much of a difference, but I was wrong! Holy cow!

I think I'll re-set-up my Belt to see if I can get it to fly this smooth and responsive.

Since it's been a month now, I thought I update about my heli. I happy to be able to report that I've not crashed anymore (yet). I got a new canopy and a new paint job thanks to my dog. I have a loft that's pretty much my space in the house. I looks down on two sides; to the living room and dining room and the family room on the other side. So, one night after a flight, I'm upstairs adjusting my Belt CP. I hear this crunching sound. I look down into the dining room only to see our 8-month old Border Collie/Boxer mix puppy chowing down on my canopy. I yell down "bad dog...no!". He scurries away, but it's too late...my custom canopy is totaled. He pulled it off the kitchen table. Into the garbage it went. The next day I ordered a new canopy along with a few other parts from HeliDirect. Even with the el-cheap-o $4 shipping, I still had it in two days (ordered Thurs, arrived Sat.). We took a trip to the auto parts store and picked out a new color...a metallic blue this time. I added a little trim with some aluminum duct tape, and she's all done.

I'm getting better at piloting this thing too. I'm just about as good at tail-out hovering as I am at tail-in hovering. I now have a set of Align 325mm CF night blades that light up...since I do most of my heli flying in the evening. Those are very cool and I believe they've actually helped me being able to see the blade disk better as I'm flying...

Latest picture.

Update 10/26/2007: This canopy has been smashed into a hundred bits when I nose-in crashed from about six feet. The heli is already back in the air and flying great...just no more custom paint jobs until I'm a better heli pilot.

This is my latest obsessionÖthe ESky Belt CP helicopter. Iíve never flown a helicopter before. Iíve logged about 20-30 hours on an MX400 in RealFlight 3.5Ö.thatís it. Iím hooked for good I think. Iíve had two minor crashes. With the LHS out of stock of the feathering shafts, Iím getting quite good at straightening them.

Parts I've gone though so far:
Straightened Feathering shafts (x2)
Main Shafts (x2)
Main Gear (x1)
Blades (x1)

All in all, this has been a very enjoyable, humbling experience. This video is my first try at hovering on a windy day. I've got about two weeks and 15 flights on this helicopter.

While flying this morning, my friend Vicarious was good enough to play videographer and photographer for me. I took the clips, some music and threw it all together. This video is a nice showcase for Grayson Hobby's GH2212-06 Motor.

I hope you enjoy it!

I've been wanting to do a clear canopy and humorous pilot modification for my SU-27 for some time. I found the time and got it done. Here's the pictorial on how I did it.

Note, the vacu-forming was a failure (I kept getting folds in the plastic as I pushed it down over the mold onto the vacuum box. Next time, I'll make a wood box and put the whole thing in the oven and simply turn on the vacuum after the plastic is ready.

Edit: Due to a couple of inquiries about purchasing my canopy, I added five more detail pictures that show the flaws...mainly, lop-sided to the left side of the aircraft....Continue Reading

After work, I took my trusty Creative ZEN Vision: M 30GB media player with me to the field. I got recordings of 4 WOT passes to get Doppler speed from. I kept it paused in my shirt pocket and I'd un-pause before I did the fly-by then pause it again until the next one. Here are the results.

It's been over 125 flights. She had gotten a little grungy. It was time for a re-fit!

1) Repaired and sanded the entire model...lots of old epoxy marks to clean up!
2) Finished Painting/re-painted.
3) New markings
4) Several coats of Minwax semi-gloss Polycrylic (spray).
5) Additional CF spars for the wingtips...maybe they'll stop breaking off now.

I'm now running (last 25 flights or so) Grayson Hobby's 2212-06 park jet motor with a 6x4E prop. Incredible!

Now she's ready for another 125 flights...

Update: No, the wingtips still break-off. I think this might be more a reflection of my piloting and not the strength of the aircraft.

From the Stingray thread in the scratchbuilt forum.

I loved the lines on this plane. I wanted something with much lighter wing loading than my previous project and this seemed to fit the bill. Start to finish, this was a four-hour build...very easy. This time, I used CA hinges (I HATE TAPE) and hot glue where ever I could.

She's a great low/slow/close-in plane. I have a problem with wing rigidity though. On maiden last night I lost control three times...all in high speed glide dives.

1) Pulled-out of it and regained control 3 feet off the deck.
2) It did crash...but barely. Slightly dented corner on nose.
3) Coming straight for me from 200ft, no control, pulling back on the stick...as it gets closer, I am just about to jump aside as it plows into the ground where I'm standing...I see the wings oscillating horribly...like a bird on coffee flapping its wings. Just before it hits the ground, it lost enough speed for the oscillation to stop and she responded and pulled up at the last second.

Time to add two more CF spars along the leading edges to make a huge triangle. That should help.

Update: I added a KFm airfoil to the bottom of the wing surface with spars behind. This solved all my oscillation/rigidity issues.

Lost orientation...too far away. Oh well, I guess I was looking for an excuse to start version 2.

The entire modification took about two hours. The whole landing gear setup weights 1.75oz. It cost me about $20. It only takes two minutes to install or uninstall it via the 5 nylon bolts. It's a blast to taxi this thing around ("here kitty, kitty") as well as do touch-and-go's over and over and over.

As expected, the gear has degraded flight performance. She'll still roll like crazy, but I can hardly get her to loop. She needs a moderate (about 50') take off roll and she rotates and climbs...not just lift off the ground. She's still very stable in flight slow and fast high or low. You do have to fly her in for the most part.

All in all, I'm glad I did this mod...I just think I need a little more power now.
