Hi All,

While cruising eBay for Heli Finds, I came across an old Concept 30 SR-T in decent shape and picked her up with the intent to restore and fly for nostalgia purposes. Maybe kinda corny, but this is the same bird I learned to fly on 19 years ago.

Are there any old Concept guys out there? It's been a long time since I was familiar with this machine. Any pro tips or lines on parts would be a help.

As you can see, she still has 90's era guts in her. So my plan is rummage through my spare and old hardware to get her airborne again. Found an extra DSM2 receiver, GY401 and some decent Hitec Servos from an another bird no longer with us. I am hoping the OS .32 in her will come to life. Still moves freely and has good compression. I plan to tear it down and give it a good cleaning. The wood blades are shot, so I think I will throw some Align Carbon 520's on. -I believe this machine can utilize up to 525mm blades from what I read.

I did notice there is a good amount of play in the main and tail rotor grips, but they are not of the usual thrust bearing and damper designs modern birds use. I noticed from photos of Concepts that the blades do have a "droop" at the grips which seems to indicate this play is by design. Any opinions?

There were two versions of this heli. Don't remember the exact nomenclature. The "beginner" version had a solid shaft/blade axel in the head and very very soft dampers. The expert version has the floppy head. The floppy heads flew great but auto-ed very poorly.

I think from memory the SRT was the beginner and the SRX the pro.

They came with 520 blades.

@ Four Stroker I did notice there was no auto-rotation one-way bearing. I remember the one I had back in the day was the same setup. -Thankfully, I never had an engine out while I flew her. Think I may look around for an SR-X one-way bearing/gear setup and swap if I can find.

As far has the head goes, it's definitely the floppy setup. as tonyd mentioned above, the setup does not use a one-piece feather shaft. Rather, it is a two-piece bushed setup.

Somebody "upgraded" the head while getting the aluminum start cone! While you take it apart look at what clutch it has. There were many updates. The last clutch has a molded in brass liner that you glued the usual gasket material to plus two ball bearings. The SS clutch is self adjusting and worked quite well. It has just enough spring to work. My Kyosho's had upgrade thin wall SS torque tubes that worked fine as well. Taya attempted to make a tiny helicopter that was as stable as a 60 FAI ship. Did a good job. But don't expect to do any 3D with it.

I have a set of all metal paddles that came on the SRT. You have the upgrade paddles as well. The SRT was designed to sit in a hover and barely move while the beginner slammed the sticks all around.

The Concept 30 lives again!

After a moth and a half of tearing down, evaluating, searching for parts and rebuilding, she has finally flown again after nearly 18 years of dormancy.

She flew just as I remembered when I first started out. Certainly nothing like my bigger 3D birds, but oddly satisfying to fly what I learned on once more.

Still have to mess with the throttle and pitch curves a bit to get her completely right. It's been a long time since flying a 30 sized machine machine without a gov, but I think the little .32 just may have enough in it for some basic loops and rolls once I get everything dialed in.

I know the feeling. I bet you are having more fun than you could have possibly had with a new heli kit.

Awesome helicopter project, Concepts are cool!

The older helicopters are lots of fun. I owned a Concept 46VR once upon a time. It was a lot of fun.

I now have a mint JR Ergo 30 and have a ball with it as it is the same as the one I learned to fly with. And if anyone says you can't have fun with an OS32, they're just wrong.

It doesn't have a auto rotation clutch ?
or It doesn't have a driven tail?

ageing is manditory maturity is optional

I might suggest changing the rear bearing on that engine before starting it - should be a nice project. Hope you'll post a video of it once you got it flying. My old school project still in a box is a GMP Cricket

@ PaulBowen

I totally agree! I do love my bigger, modern 3-D birds, but I find it oddly satisfying flying this great little machine. -That's a beautiful Ergo you've got there!

@banshee rider:
This particular model did not have an auto-rotation one way bearing setup on the main gear. I picked one up on ebay and installed it.

@jschenck:
I tore the engine down before I first ran it. Found virtually no corrosion, pitting or wear. Simply had to replace the backplate gasket as well as the carb and needle O-Rings. Bearings rolled smooth and overall, looked to me that there weren't many flights on it. Plus the previous owner oiled it up well before storing. I certainly lucked out.

I posted a small video of one of the first flights, not great quality, but I'll get a better one up hopefully soon.

Cool video!

My OS32 just loves to run. What I never realised with my first Ergo in 1997 was that the 32 flies mainly on the low needle. Once I realised this the tuning became a lot easier.

What I really love about flybar helicopters is that you know that it is you flying the helicopter more than what we are with a flybarless system.

Yeah, 3~4 sec pinch test. Enya #4 better on 30%.

I'm running Powermaster 20% heli in my models.

I usually use OS 8 or Enya 3 plugs although I do have some Enya 4's, I'm just not sure when and if to use them. I originally had the Enya 4's for an OS 105HZ-R but couldn't detect any difference.

Love it! This is giving me the energy to restore and old 46VR I've had on my shelf for 15 years!

Great video!

I still have mine (inherited from my dad) and it needs dug out of the attic. One heck of a bird, I don't recommend doing flips because if memory is correct the flapping head will boom strike. Mine has an auto clutch, it was my Dad's personal flyer so he might have upgraded it at some point. FYI, I still have my original Cricket!!!!!!!!!! and some where a Schulter Mini Boy!

AND I still fly my 1995 Hirobo Sceadu (all the upgrades), did upgrade the motor a few years back with the powerhouse OS and matching pipe and it is now a pretty decent machine that I currently fly.
