Airfield Sky Raider

This showed up last night so no work on cleaning up old cars....I built this instead. It is a 32" wingspan plane...and it is a little plane, runs on a 1000 2s battery that is (from what I have read) 5-7min of flight time. It is to have a pretty high wing loading so it likes to be flown fast. No chance to get the first flight in...and it looks like it may be a little bit with winds in the 20mph range. Just too windy for a little bird.

Here are some pics...tonight I am going to do a little wright up on this plane on rcgroups...and I can cross post it here if you would like.

I will say this is the first new plane I have bought in about 2 years....WOW is all I can say...just wow, the detail, fit finish, paint, decals....hell everything is just mind blowing. I don't think the photos I took will do it justice. I bought the RTF and that had everything you need to get the plane in the air less 4 AA batts....all for less than $100, and that included shipping. The plane went together very fast, no issues...I will post up a post flight review when it calms down....hopefully it will be less windy just before dusk tonight.

On to the pics....I will get a pic of the finished plane tonight.

I combined RC components with a camera and a motorcycle to make a gyro-stabilized camera mount.

MotoGP developed some gyr-stabilized camera systems that can provide live TV-quality video feeds. As you can imagine, the technology, while spectacular, is complex and expensive.

I learned about piezo gyros and that they'd been miniaturized along with servo motors for RC aircraft and helicopter use. Eventually, I found the Dunehaven GS-1, which is a combined gyro/servo in one package.

We have SolidWorks and a 3D printer so I set out to make a housing that would support the camera on my SV650S track bike. I used the mounting bracket from a GoPro camera, since they seem to be most popular for this application.

My first test prototype to test the concept was very crude, using a keychain cam.


But it worked!


As you may be able to tell, there is a problem with the gyro drifting back to center. This setup was small and cheap enough to be willing to live with it. The newest model decreases the amount of drift. I investigated going to something that would hold the heading better, but it appeared I was going to need what amounted to a helicopter autopilot, increasing the cost 3-4X.

I continued to work on the packaging and got a GoPro. Eventually I took this setup to a track day.


And I'm pretty pleased with the results. Especially for a product that is well less than $200 (excluding camera) to put together.


Thank you RC community! I'll have much better packaging for next year.

any recommendations on a motor?

will be my first tamiya RC, wanted it when it came out, never got it, now catching up with my days from a while back

Well, you could always use the stock 540 motor. I always liked Trinity motors though. I think I had a Joel Johnson Modified in my Hot Shot II. I have a Trinity Ruby 13T in my touring car that's a lot faster. Not sure what's 'good' right now though.

This might work well for you and would allow for lipo use - http://www.oomodel.com/ezrun-35asl-e...db1-p-353.html

The motor is a 380 core but has plenty of power and should not over tax your drivetrain. Here it is in action.

Nice!! Have you used those OrangeRX receivers before? I just ordered a couple from Hobby King to try out. $19 for a 6-channel with a sattelite receiver. Way better than $90 for a Spektrum, if it works ok. Worth a try.

I haven't tried them, nor any Turnigy products.
This whole project is all about trying a bit of all the turnigy products, and the Orange receiver.
Depending on which of the zillion threads spread across RCGroups, and RCU, there's a even blend of love and hate for the Orange RX's.
I got the plane for "free" (won it at SEFF, so you know how free that is...), so I'm willing to sacrifice it in the name of testing, and shakedown.
I have a few other electric projects waiting in line to try, and if these prove to be good on the RV-9, I'll try them on the Rhapsody, next.

PS, I didnt know how big that speed controller was going to be.
It's rather large. Hopefully I can find enough room to tuck in out of the way.
They were out of the Sentry ESC's I wanted to try, as well as the Plush.

BTW, I ordered this batch of goodies 12-29-11, iirc, and tracked through Swiss Post, and received them (South Louisiana) yesterday.
I have another order I placed Jan 3, that appears to be tracking through Chinese post, or something of that nature. I see there was a notice left of it's delivery today. I'll have to get it tomorrow, when the post office opens.
I ordered a couple sets of Turnigy nano LiPo's from the USA warehouse, and they showed up in 2 or 3 days!
I hope they'll beef up thier USA inventory, because cheap, and fast is a great thing!

Kinda what I have in mind too for the Orange RX; a cheap foamie that won't break my heart if it crashes. I'll be real curious to hear what you think about it once it's flying!

We've used the orange one's, seem to work fine. I just got 2 more. I've heard you occasionally get a bunk one, but at $6 a piece.....that's fine.

What have you used yours in?
How far out have you flown them?
Some of the frequent thread mentions were about them having a short range.
I bought them under the pretenses that they were a full range receiver.
I didn't get the satellite receivers, either. Didn't think I needed them at the time.

That is cool!
This caught my eye because I built a servo controlled webcam, I could easily replace one of the servo's with that Dunehaven GS-1
Gyroscopic stabilized servo's... geez technology marches on!

So if I had around $100 to spend on a flying toy, what would y'all recommend? I'd prefer a heli, but that Airmaster looks pretty sweet... Pretty much open to anything that requires more skill than what I have, which means pretty much anything. Suggestions?
