Thank you, Gentlemen for your comments regarding the wooden blades. My flying style is very "old fart" and I enjoy flying in as scale a manner as possible. I spent some time today installing some of the servos and sizing the ball links for minimum friction.

I'm setting it up with Spektrum digital servos. The gyro will be one of my trusted Futaba 401 units. I'll order the recommended Thunder Tiger engine this weekend. If all goes well, I should have it ready to fly in a week or two. I'm in no hurry and want to make sure it is "right" when it takes to the air.

It sounds like you didn't get a motor yet. If i were you, i would look at getting an OS 37.

Servos are mounted, linkages are made up and adjusted, and other than the throttle linkage (motor will be in this weekend), mechanical setup is complete. The canopy is trimmed and mounted. Tomorrow will see the wiring being neatly routed and secured and the "stickers" applied to the canopy.

With any luck, this should be flyable in a week or so!

I ordered the recommended Thunder Tiger .39H (R) engine and associated muffler. Others recommended the OS.37, but the cost of the TT engine was low enough that I couldn't ignore it. This heli is only going to see gentle sport flying, so the TT engine should be more than enough.

Oh, I still have to epoxy the main blade root grips in place and then balance the blades.

I finished up the wiring and gyro setup today. All I need now is the engine and to set up the throttle curve.

This will be my first nitro heli since the mid 70s when I had a Schluter Heli Baby and Heli Boy.

Interesing. TH indicates that the OS engine is discontinued and recommends the TT engine as a replacement,

Ive had great luck with TT engines (.39, .50, .53) I think you will be very happy with that setup.

Talk about being years behind the time, my NOS Raptor 30 V2 is almost ready for its maiden flight. I seem to be having a binding issue, quite unusual and the first I've had with my many year's use of Spektrum based radio systems. While the airframe is ready to go for sure, I'm not going to even think about flying it until I get the radio issues resolved.

Very neat. Consider a 6V pack for the 2.4GHz stuff. If you go to 6V make sure all your electronics can handle it. A regulator may be required. Can't help with the radio issue (different brand).

I made my first Rappy 30 fights yesterday. I used a tank of fuel setting the idle and hovering several inches off the ground. I then hovered out a second tank about 3 feet off the ground. Tail rotor response is funky, so I'm going to change out the Futaba 401 gyro to another unit. I hope to put at least two tanks through it today.

Other than the tail response, the mechanics are smooth, cyclic response is crisp, and overall I am satisfied with this project.

The motor is set at a "fat" 2-cycle and seems to have adequate power for my sport level flying.

OK, the tail issue was not the Futaba 401 gyro, but a servo going bad. Changing out the servo solved the tail issue.

As of yesterday, I have eight tanks of fuel through this heli. It flies quite nicely with my "old fart" flying style. It's not as noisy as I anticipated, but the SMOKE!!!!!!!!!!!!!!

I have enough room to fly the Raptor on my property, but this thing lays down quite the smoke screen. The wind was relatively calm yesterday morning and one of my neighbors wandered over to see what was burning. He enjoyed watching the heli, but certainly didn't enjoy the smoke screen.

I have no issues with my neighbors in regard to my electric powered helis. But it looks like I might want/need to hook up with a club/flying field for when I want to fly the Raptor. There goes the advantage of just walking out my back door and flying!

That is cool to read. A step back in time.
Glad it is working out good for you. The 401 is a great gyro. I do love the smoke and the sounds of nitro.
That is a great learning heli. Good fuel economy and flight times when properly leaned out.
I am still regularly flying my Raptor 30 and still love it.

The local hobby shop where I purchased the Raptor 30 was averaging one sold a week until the electrics came along. They said the bottom dropped out of the glow fueled helis after that. If that's case, there must be a bunch of Raptor 30s and similar in the southern Worcester County area that are languishing away in someone's garage or basement.

I just finished the setup and test flights of a gentleman's Kyosho Shuttle, also bought about 10 years ago and never flown. The guy never managed to start the engine. On my first exam of the heli, I noticed that it had no glow plug. When I mentioned this to the owner, he said "What's a glow plug?" I guess that about said it all.

So after not flying glow powered helis since the late 70s, I find myself the owner/pilot of one and helping to bring older helis back to life.

Oh, flight times. I'm seeing 12+ minutes with 1/4"+ fuel level remaining in the tank. And the tank is not completely full to start with. So far, the Thunder Tiger .39H ringed engine is proving to be a reliable performer with more than adequate power for the Raptor 30. At least for my "old fart" circuits!

I have been looking for an old school nitro heli to have as a vintage bird in my fleet (my others are electric/flybarless.). I decided the Raptor 30 would be the one to have, as I always wanted one, and parts are still around for it. I looked at some Kalt Baron 30s, and Hirobo Shuttle ZXXs and Sceadu's, but parts availability made me stay away from those. I know RCJapan carries Hirobo parts, but I felt it would probably be easier to get TT parts here in the U.S.

I picked up this V2 (was the RTF) without the Ace transmitter/RX for a pretty good deal. The only probs are a bent tailboom and rear LG strut is broken near the frame.

I'm swapping the slow analog servos out for Savox digitals for cyclic/collective, using an Align DS620 for the tail with a GY401, and using the Ace digital tail servo that came with the heli for the throttle. Going to run an 8 amp regulator set to 6 volts, powered by a 2S LiPo. It's got a cool flag switch with a "Remove Before Flight" flag (mounted to the frame behind the header tank.) the reg powers on when you remove it. I also added a Pushglo. I'm going to run CF main blades and OEM Raptor tail blades.

I moved the tail servo to a rear mount CF also (going to make a CF pushrod) and put on the header tank/refueling plumbing.

Old-School...I love it! Gonna run old-school throttle/pitch curves too!

I forgot to mention, the previous owner just used the stock settings and made no adjustments to the heli, but I found that the servo to bellcrank geometry was way off, as was the collective. The throttle geometry was off slightly too. Needless to say, this is all being corrected. That's my next step, to find my servo centers, set 90s, level swash, etc. the head is in excellent shape, but I'm going to pull the grips and check bearings/re-grease thrust bearings.

What is the scoop on the TT .39 pro? I have a NIB O.S. .37 SZ-H, but figured I'd give the TT motor a shot. I did have one flyer tell me to keep the low-speed metering screw set as rich as possible as it affects hovering throttle, and if you lean it out for a reliable idle, it will be way too lean at hovering and transition. I guess the trade off is setting a higher idle speed to keep it from loading up. That should'nt be a big deal; every Raptor I've seen seems to engage the clutch at a pretty high RPM. Then I was told to set the high speed needle for best performance during a fast collective climb, and then set a few clicks rich. Does everyone with experience with this motor jive with that?

Here's a few pics of my shop....as you can see, I'm into bikes and beer too!😎

I went with the TT.39 in my build as it is still available from TH as well as some other outlets.

As for parts, my LHS has a good supply of Raptor 30/50 parts and they seem to be available from many on-line sources.

The way this thing flies, I should have it for a good long time unless I "dumb-thumb" it.

Great find, enjoy your heli, it's a great flier!
