Hello, after hours of research here on RCU and other sites, I'm seriously considering the Tiger 60. A great looking and flying airplane. However they seem to be tail heavy. Further research indicates a 4-stroke seems to help.

I know very little about 4s engines. I prefer to stay with 2s for know.

If there is someone out there that can help, it's greatly appreciated.

Help

Thanx

`Sure, we can help. My second was a Tiger 60 and I loved it. I just sold it to a fellow RC'er and he is flying it as i did when I first got it. A great aircraft.

Best of all, it's a 60 size do it's visible up there. Then it is easy to see when on approach and landing, you can see your inputs as you move the sticks. Great aircraft.

When I built it, I had the OS 61 SF engine. This powered it just fine. I later had to get the bearings replaced on the OS so I bought a Super Tigre 75 and later put a tuned pipe on this. Wow.. what a performer for what was called a low wing trainer.

Highly recommended. Go for it!!!

Thanx for the info.. great. How did the cg work out with that OS. Thinking about the same engine.

Get the new OS 75AX It weighs about the same as an OS 91 4-stroke and it is a SWEET engine!

Second that from Minn Flyer. The OS 75 AX is truly a sweet engine. Mine runs like a clock!!

As far as the OS 61 SF engine was concerned, it flew it around just fine. I eventually had to remove it to replace the bearings, and in the mean time, I put a Super Tigre 75 on board. It was wierd.. the inside of the muffler came apart, the plane sounded like a sliegh bell as it passed by. Super Tigre replaced it, but the new one did the same thing. So, I put a MACS Tuned Pipe on that thing. Jeech.. plenty of power with that, but it leaked fuel, right out of the needle valve assembly. But, it still runs, I sold it to one of the club members a couple months ago, to make room for other.. new models.

Anyway, no matter, if you go for the OS 75 AX, you can't go wrong. As we both said, a truly sweet engine.

You got that right. Mine started on one flip and idled well right out of the box. After a few flights I leaned the low end just a little but that's about it. People look at engines like this and automatically think they are over-priced. Well, you get something for that price. You get a no-fuss, strong running engine that will rarely let you down. To me that's a better value for my investment than something that may cost less but gives me trouble.

Wanna see a Tiger60 with an OS75AX on it?

Here is mine. It's a great combination. Excellent matchup.

As for any worries about being tail heavy, don't sweat it. The airplane is one of the best low wing trainers ever. It was designed to be an entry model for people learning to fly pattern. It tracks like it is on rails. The only thing I don't like about it (ready for this?) is that it really does not want to tip stall. It's really hard to snap roll the thing because that straight wing isn't going to stall. That also makes landing the sucker a sure bet. You are not going to see one tip stall on approach.

Great airplane.

Oh, about the tailheavy bit..............

I've been moving stuff aft to try and make it snaproll. I'm going to have to put a kitchen sink in the rear next.

A buddy has been watching my TigerII and Tiger60 fly for a year or so. He brought out his latest the other day. A Tiger120 he said he got because he knew it would fly great. He had about a pound of different kinds of weights in the tank compartment to keep the CG up front. He wound up pulling a piece every flight. It flew every flight just like the previous. The only thing that changed was how effective the elevator was. The CG the last flight was somewhere way back from the spar. It flew great. We had quit checking the balance after pulling each piece and just flew the sucker to see what it did..... we were tired of picking it up with our fingertips and figured that just made us nervous. The CG was DEFINITELY behind the recommended location. Figured we didn't need to know, and figured the airplane didn't seem to care. And it turned out to be that way.

They are really good dependable flyers.

Hi Guys,
Thanx for all the great responses. I'm sold on OS engines. Getting ready to put a 46AX on my WM SS 40. And I agree that you do get what you pay for.

Thanx again for the help.
