What kind of trainer do you have?, what is the wingspan, length etc.?

I would sugest an OS just because I find it easy to work with(adjust and learn with) and they'll do the job.

would use TT,or OS, first time out to be safe.

I agree with the smurf. OS engines are very user friendly. If you have a standard .40 size trainer, a 40 LA will be perfect. For example, last Saturday I helped a glider guy with his first powered plane. It was an H9 Solo Sport with 40 LA. He ran one tankful on the ground the night beflore we flew. We flew for 2 hours whithout one hicup. No of deadstick landings - 0. I've flown one on my club instruction plane for 4 years and its in great shape. The only time I have deadstick landings is when my gas tank gets filled up with air. Hehehe

Thanks, I am building a Basla USA Stick 40 with strip ailerons and conventional gear with a free swiveling tail skid. Two friends from work suggested a Super Tigre or an Enya. They both have been inactive modlers for 10 years or so and we wonder what was a good engine now.

I have had extremely good luck with Thunder Tiger pro engines, they are cheap and run very well along with being easy to tune, it is the easiest engine I have tuned next. OS is another good runner that is easy to tune but is a few more$$$$

i am relatively new,but i have several engines and the thunder tiger is really hard to beat for getting in the air. i have a tt .40 a tt .40 pro and a tt.54fs 4 stroke. i think the .40 bb pro is better than my .46 magnum xl. just my opinion.

The TT Pro series are good engines. Stay away from the GP series. Magnum engines run well and the price is right. I have run several Magnums and they all have run well. The only Magnum I don't recommend is the 1.80 2 stroke. Enya and Super Tigre are very high quality engines and they run very well also. The OS LA series run ok, but they are not Ball Bearing engines. They use a bronze bushing to support the crankshaft. This bushing tends to wear out causing erratic idle and can be messy on the front of the plane. The cost difference between a Magnum 40 BB and an OS LA 40, not enough to worry about. The bearing motors will last much longer and provide more power.

I messed with a students Magnum 40 XL all summer and it still isn't running right. Great power sometimes though, but not worth the headache .

I've never run TT, but have seen many good posts about them.

Stay with OS. Reliability is worth more than anything.

I'll second the thumbs down on the Magnum engines, everyone I have ever seen is only good for a paperweight or if you tie a string around it it could be used as an anchor for a small boat! This is not to say that there are no good ones out there but this is my experience. Thunder Tiger is right there with OS on the reliability scale with OS, I believe they were designed by the same guy that did OS, Don't remember where I heard it, does anyone know if this is true?

RVator:
in what type of surface are you looking forward to fly??

I fly in plain dirt mixed with little salt and sand!!, I fly in land´s end in BAJA mexico, OS la 40 still runs after 2 1/2 yrs, it has been in 4 different planes, now a days it flys a old timer "buzzard bombshell" no complains, after-run oil helps!
two magnuns in the club are gone in that same time, due to the terrain hte engines end up over heating, I guess litlle salt & saand are as though as it gets.- OS la 40 still holds it´s own.
certainly no ball bearing in the front but for your first plane you don´t need it and later I can bet you´ll find a nice little plane for it!!

Stratotanker- I have heard the same storie about OS and TT The guy was supposadly one of OS's engineers and got mad at something and went to work for TT- At leasts thats the way I remember it

That is the same story that I heard, must be true!

I went with the OS 40 and it worked very well with the Super Star Select.
That craft has some big flat bottom wings but the engine did a good job.
I would say that it flew appx 40 MPH.
Landins are very slow and easy on the craft

Never had a magnum but I have to agree that they are poor engines because... As one of our members at the flying field who has one said "oh don't let any one else tell you otherwise, they are a peace of sh*t(sorry thats what he said), but they are a lot cheaper then OS or Satio and I guess you get what you pay for". I think for the most part "you get what you pay for" is right on the dot. Oh yeah he had fuel leaking out of his header= lost of compression but it still run though.

I have a Magnum .91 4 stroke that runs great! I also am training someone with a .40 2 stroke that runs very well. I have helped others with Magnum engines and have yet to have a bad one. There are sometimes when someone produces a quality product at a good price (Super Tigre, pre-Chinese). I also have several ASP engines (Another Sh%^&y Product) but they are screamers! I paid $100 for an ASP 1.20 from Horizon's Attic. I keep looking for more! Old habbits are hard to break and that's ok. We all don't like the same thing and that's what makes it interesting!

I have two ASPs and they run like champs. My .46 has been flying on a Tiger 2 for almost 7 years without a hiccup. I have worn out two needle valves and am on the second set of engine bearings but that is to be expected on an engine with this much time on it. The plane is on its third set of tires and its second set of wire gear. you know you have flown a plane a lot when you are taxiing and the wire gearjust folds under! The plane has over 500 flights on it, it gets refurbed every two years, new covering etc.

My .61's are real runners. My 1.20 took awhile to break in but now runs very well on 5% nitro (Cheap!). My buddy has a .46 he rebuilt after tossing a rod (many hours of time) and folded the wings on his Telemaster .40 with it! The carbs are the only real problem, they are good or bad no in between. They also tend to leak a little. Keeping the o-rings replaced solves this though.

How much are you paying for the 5% Nitro?
A few clicks up I left a link for a place not far from me.
Tower Hobbies has good prices on the gallon but they only sell 4 by the case and so your charged an extra haz-mat fee.
But you can buy all the quarts you want.
Just don't under stand that

Thanks everyone for the engine info.
To Mancha, the flying fields in my area are all grass. One of the managers at work flys R/C and has got permission for a field at work. I hope it works out.

I must say from reading everyones post that an engine is like an old wife, some times you just want to shoot the thing but its another story to have people talk trash about her hehehe

The other half just may read this and when your at work She'll put the match to all your models
Then no hehehe

I didn't see the link but, I did just get home from working grave shift! Actually I buy fuel from Musser's out in Buck Pa. If I run out I can get it locally at H&R in Northfield (S&W about $11 a gal.). I will be placing an order with Morgan Fuels in the spring for their Mach 7 brand but that will only be 15%. I buy 6 cases at a shot and they ship by truck ($12.80 per gal.) to my friends gas station. Since it goes by truck, there is no haz-mat fee.

If you will be flying off grass id highly recomend going with the os .46fx, or tt pro .46. At the very least get the os 46la. Id stay away from the .40la. If the grass gets thick and or high you will have a tough time taking off. It will however to teach you to fly off the wing and not the motor. I had a weak engine in my trainer when learning and many times could not even gain enough speed to take off, had to hand launch it a few times. I bought a os .46fx and had no problems what so ever, plus the engine will fit nicely into your next model.

good luck!!
