I would like to purchace a .71 engine , can anyone recomend a good brand name and web site to purchase from. At Tower, there is Fox,GMS,O.S. , Super Tiger, Thunder Tiger and Tower Hobbies.
Tower Hobbies .75 Ball Bearing ABC Schnuerle is the cheapest....is this engine any good or should I stay away from it?

So many decisions....so little time

Thanks

What's engine going on?

From your statement I presume you are looking for a 2 stroke.

OS and Thunder Tiger are excellent engines and you will not go wrong with one of them. The GMS engine is also a very good engine AND extremely powerful, but it does require more "fiddling" with than OS or Thunder Tiger to get running right.

Tower engines are made by GMS but with a different carb. I have had the Tower 46 engines. With the 46's I have had, the power was excellent and the transition and idle were quite good. The bad news - they will not shut off with the transmitter. Perhaps 1 out of 5 engines will shut off with the transmitter. I don't know if this carries over to the 75 or not. To me, not being able to shut the engine down with the transmitter is a MAJOR safety hazard and an ACCIDENT WAITING TO HAPPEN. Other users of the Tower 46 have also reported poor idle and transition in addition to the shut down problem.

I have not heard any reports of the GMS not shutting down with the transmitter. Paul McIntosh

is the person to contact about the GMS engines. He has quite a bit of experience with them and can tell you the ins, outs and quirks of them.

If you want to go with a 4 stroke, get a Saito. User friendly, runs great and sips fuel.

Hopes this helps.

Either the TT or the Super Tiger would be my choice of those listed. I like the Super better. I have one to go into a Top Flight AT-6 someday. One other that I would reccomend, MVVS. They make a 77 that is real strong. Will put out tons of power on low nitro fuel. Quantum models and Morris hobbies sell them. With a tuned muffler they are an animal. I have 2 40's that are almost as strong as most 60's. Good luck with whichever one you end up with.

I don't think OS or TT makes a .70 two stroke. Fox is probably the best on your list, with a lifetime warrenty and great service. The carb problems are fixed. The only problem is that you cannot use more than 5% nitro fuel without modifying the head button. The Super Tigre is probably the next best, followed closely by Tower.

The Fox is an heirloom engine...Take care of it properly, and it will last longer than you will, and it's American-made.

The Irvine .72 would be a good choice. The .72 is in a .61 casting so it is space efficient and puts out about 2HP. I have 2 .61s, 2 .53s and 1 .46 and they are all great engines. They are a true ABC engine as well!

Well, let me put it this way if you want to be a pilot go with OS, other wise you'll be a mechanic and then a pilot.

I would echo a few of the previous suggestions and stay away from the Tower engine. I love my TT Pro, it runs like a champ.

Super Tigre

os os os os blah blah
Read the forums and see who has more problem posts.
Im a pilot and have never had to take apart my TT or ST. They Run hard and strong.
I drive a ford but Im not close minded about Chevy.

Easy answer FOX!! there is not better engine out there.

Super Tiger or TT..

I would personally go with a Super Tiger 75. I have 4 Super Tigers, 2 75's and 2 90's. Once they are broken-in they are very powerful and very reliable. Tower Hobbies has the 75 for 119 bucks at towerhobbies.com. Can't go wrong with 'em.

Super Tigre and thunder Tiger are simply the bast strongest running engines on the market.... I hated my O.S. engine both in truck and planes Sold them for ST's.... Try one there will be no turning back...

Ok.....Look like Super tiger 75 is what I am going to get. Does anyone know if you need to get an engine mount for the Sig 4* arf, mine should be coming in the mail in the next couple days.

Your ST75 should be a good match.. The supplied mount will
work with the 75.. At least it did with 4*60..

I love my O.S. I haven't had a problem with any of mine
I love them so much I even have O.S. branded on my arm (backwards, be carefull with hot engines )
