I just received the Novarossi .50 w/ Ultrathrust muffler from Planet Hobby a few days ago. I'll post a review when I get it running a month or two. Putting it in a GP Tracer for now. It sure is one sweet looking engine though!!!

I bought a couple from Macs some time back..I have a pair of the X45 RE STs..and then I picked up one on Ebay for a X40 RE ST I have. I don't really want to sell it, but I would if you found a plane for your X45 and the only thing holding you back was a header.

Tweet, huh?? I haven't seen (or HEARD!!) a Tweet around here in a while...

Pics of my tiporare: 56 in wingspan + o.s. .46fx + macs header and tuned pipe + eclipse 7, taildragger, rudder kevlar pull-pull, very fast, no bad habits, very accuracy.

....from the top....it looks like a Killer Kaos....

With respect.

I try again ! I fully understand you nostalgia, but will anyhow buzz up the discussions with a few facts. 1. A smaller plane with a noisy engine at a high RPM is always thought to be faster than a big, quiet plane with an engine at low RPM. 2. A fast (not very accurate) calculation of prop pitch and RPM reveals the following : A prop with 7" pitch at 15k idicates a speed of 44.5m/s = 160km/h, a prop with 13" pitch at 8k idicates a speed of 44.0m/s = 158km/h. Not that different, huh ! In addition comes the fact that the bigger prop is more efficient and will generate more 'overspeed' due to propeller lift than the smaller one. I did measure the speed of my OS-140RX-FI equiped ZN-line Alliance with a radar-gun during easter, in a shallow dive it was close to 220km/h ! The seemingly low speeds during todays F3A schedules is not due to lower speed of the models, but a result of the flying style that requires throttle management. Then the models is made to be able to fly well at lower speeds. Do not missunderstand me, if you have fun flying a 30+ year old design with a lower power to weigth ratio than todays norm, feel free. The whole ide of this sport is to have fun !

The difference between my Tai Ji with ys. 91 and my old Eclipse with OS 61 RF and tuned pipe is fun factor. I'll agree the Tai Ji is a better flying plane.

The best anology to owning these two planes is driving my two cars. I am fortunate enough to have a BMW 5 series. It will do everything better than my 1990 Miata. Faster, more comfortable, more stable, better handling. Somehow the Miata is more fun to drive.

Thanks for your comments, but i have fin whit a 30 years old pattern plane, i do knife horizontal eights, i push into a vertcal from a knife flight, very impressive spins, snap rolls, hands off recuperation, low speed landigns, long vertical flight whit too acuuracy in rudder, i was disapoint whit the weight to power ratio, this tiporare has a extra power for this weight, it's a smaller version 56 inch wingspan.

In my field the people tell me that waooo it's a tiporare?, looks great!!!, it's a 30 years old design!, but the modifications make the plane a different pattern style!, fly better than it looks!!

In fact, i do almost of the today pattern secuences, and the cost of the plane was the fourth of your alliance!.

I know your alliance it's a better plane, but my tipo it's a pure blood pattern plane!, whit more adrenaline!

Well, I got the bug again. I put a new Bluehead in my old Kaos. It flies as good as ever. I'm almost finished with a Tipo and a Mach 1

I almost sold my old pattern kits. Sure glad I didn't. If any of you guys from the Richmond, Virginia area are interested, we are in the process of building a first class model field ajacent to our private airport in Amelia County. The runway itself will be 700 to 800 feet X 100 feet.

With a small amount of effort, you can get the exhaust tucked under the Tracer tank compartment. I did it with a 46FX and Jett Stream muffler, which I believe is nearly identical to the ultrathrust. Although now I have a quiet pipe on it.

Jim....that is a sweet setup! How much does the head stick out of the cowl? The novarossi is a little taller than the OS. Did you just have to cut that notch in the firewall? What else did you do? I may go for it! More pics would be great.....

Thanks,
Beau

The head sticks out one inch.

Unfortunately I don't have more close up pictures of the muffler installation.

I did have to cut the notch out of the firewall, and make the tank compartment cover. I didn't find it too difficult, just a bit of ply as a sort of frame, and 1/32 inch ply to form the channel. There is enough space to put in a 10 ounce dubro tank. The tank center ends up aligned properly with the carb.

The extension is 1/2 inch. 3/4 would make things a bit less tight. The extension has the added benefit of lowering the tuning rpm of the exhuast a bit - which I view as more suitable for this type of plane. (The Jett is tuned at 15000 rpm)

Note, it is *not* tilted at a 45 degree angle. It is something less than 45. I just placed the engine over the firewall and estimated the position so that I could get the blind nuts in place before gluing the firewall to the fuse. Use a compass to draw a circle centered on the indicated engine center, and passing though the indicated (i.e. the punches on the die cut peice) blind nut holes. The location of the blind nuts for the rotated mount should fall on that circle to ensure the center does not move - if that makes any sense.

I really like it.....but the ole .50 is just too big to make it work and the ultrathrust will be too deep into the fuel tank area. Checked with the plans and didn't really like what I saw. Guess I'll just stick with the standard mounting. Maybe the idea will come in handy for a future project though.

I have a Superstar EP electric and Avistar 40 at home waiting to fly (stay with me here). Spent winter on a flight simulator, dusted off my Futaba radio. First radios were a World Engines Expert and Kraft systems. I have not built a model plane in 15+ years. Got the rc bug with my first issue of American Aircraft Modeler (December 1973), the cover featured Bob Violett's (BVM) 60 pattern plane Shrike. I still have the plans 31 years later, even though the fibreglass fuselage is unavailable. Maybe one day I will learn how to lay up a fibreglass fuselage. Had a sweet stick, falcon 56, kadet and sig kougar. Watched the senior pattern members fly dirty birdies, mach one's, saturns, Curare's. Etc. I just purchased plans for the Minare. Used google to translate the German to English.

I want to in the next few years, I hope to fly some of those models I saw as a teenager. ARF's are nice, I still get pleasure from building.

Happy Flying

Man, this thread brings back memories. I never flew that UFO, but it's still on the wall....with about 1/2" more dust

Great. Now you've got me wanting to build this Curare again.

IMHO I think it is a truly a shame that a few people would want to take these absolutely beautiful, awesome, and timeless pattern designs and hack them into tail dragger abortions. These designs are from an era when pattern flying was a spectacular event and the pilot skills demonstrated with these designs were and still are incredible. Kudos to those of you that embrace the concept and fine nuances of these timeless machines and real pattern flying!

Thanks to the SPA real pattern flying is still alive! Mickey Walker deserves an award for what he has done with the SPA http://www.seniorpattern.com/planes.asp

Hey Guys.....

I've been trying to get my old Aurora back in the air (after collecting dust for about 12 years).

Anyone out there have a 1988 vintage short-stroke YS 60 RE in operating condition they may wish to part with ?
I have a long stroke and an OS 61 pumper, but neither will bolt directly in without me messing with the front end.

Drop me a PM or email
Bob

Hi there,

The Tornado 88 plan 370 from the September of 68’ issue of RCM is a real good old school pattern plane. It’s the teal one next to the pool

The Dirty Birdy plan 602 from the June of 75’ is also a lot of fun. It’s the one with the black canopy.

I just got done with a Gitano plan 1165 from the April of 94’ issue of RCM. It has the plan form of a modern pattern plane and the one in the article used a the Hanio .61. How ever If you are serous about using a tuned pipe with this plane, have plug in wings, removing the pipe every time you remove the wings is a bad idea. I just installed a GMS .61 on its side and installed fixed gear to reduce the amount of “BS� I would have to go though to get it in the air. The plane is very completion ready for aircraft in its class. This is the red and white plane.

Having originated all this nonsence, time for an update.

Bad news is my Eclipse is probably toast. The engine stumbled on takeoff and while the fuse is repairable the wings are badly hurt. The engine was getting low on compression, I figure over 12 gallons of fuel has run through it. I have a new piston and sleeve for it and will probably install new bearings.

The good news is I stumbled on this old thread while searching for information on my "new" Curare. It is an untouched original MK kit with fiberglass fuse, foam sheeted wing kit and "new" in package Spring Air retracts. It even has the speed brake flap option! Thinking of putting her together soon. Unfortunately I sold my Hanno motor but still have options.

Debating on whether to use my rear exhaust pumped os rf or I also have a nib side exhaust pumped os 61. Thoughts?

Side exhaust is easier, but rear exhaust looks cooler. [8D]

I went against the grain some years ago and mounted a RE Rossi .61 into the nose of a Tiporare. What a pain it was to shoehorn the engine into that narrow nose. But I did it, and it sure looked cool with the pipe slung under the wing centerline (I modified the plane with a removable half-bellypan and semi-pipe trough with appropriate reinforcement in the wing). If I had it to do again, I'd go with a side exhaust engine. The Curare might be a tough one to find that weird Magic/Curare RE header for, unless you have it already.
Any .61 engine that runs strong should make it a bullet.

Thanks for the tip. I think I'd like to go with the side exhaust. My Os silent pipe is long and looks like if I go with the RE motor (mounted sideways) it may interfere with the speedbrake function and spoil the streamline looks of the plane. If I go with the side exhaust it will look cleaner, but I may have to make a header up because the drop looks greater than anything I have. I guess with the pipe under the wing it would may make wing removal more difficult also? Debating on taking the easy way out and go with a performance specialty muffler but that would not be "classic".

The internal system on the Eclipse was nice. This plane is also much smaller than the Eclipse. Almost .40 size. Should rip with the right setup.

I have one of the Great Planes Tipos and it is a very good kit. I hope to fly it soon!

It’s great to see all the discussion on the RCU about these pattern aircraft. I believe you should fly what you like and I like the vintage stuff.

Hi guys,

I just picked this plane up for $625.00 came with retracts os 91fx with tune pipe all servos. And I have flown it two times and love the plane. I'm having motor problems cutting out while flying and two dead sticks. any help on this would be helpful........THANKS

Hello,

Check for gunk inside the carburetor, fuel pick up, needle valve.
