What kind of engine should i get. FX or LA (ringed or unringed)

I would go with the FX but neither one has a ring. The LA's are plain bushed and the FX is ball bearing and an engine that will suit your needs down the road better then the LA.

fx all the way!!!!! the .46 fx has almost the same power as my .65la figure that one out....

I think it depends on what you are puting it in. I have a .65 LA that is about 3.5 yrs old and it is still running flawlessly. It is in a trainer. People give the LA serious engines a bad rap, but I like them for cheap planes. If you are building an aerobatic plane, I would definitely go with the FX.

Well, I have both the .46 LA and the .46 FX, and used them both yesterday!

The LA is in my trainer, and the FX is in my EasySport

It actually depends on what you want, the LA isn't as bad as most people will say, It's the 3° season with the LA and it is still running good. It's perfect for trainers or other slow flying planes, and cheaper than the FX

If you have a more aerobatic plane however I would suggest the FX, it has definetely more power which is required for those things. The LA in my easy sport would not give it unlimited vertical, as the FX does!

I've used the .40 LA in a .25 size pattern plane and it is awesome, close to unlimited. The LA's are so light they can be used in smaller planes that need a little more omph. Best of all, the LA 40 costs half of what the 32 SX does. In a 40-size plane though, I'd go for an FX if you can afford it.

dont get me wrong.. i love my .65 la just as much as the 46fx. but i was just saying that to compare the two they are close in power output.. the biggest thing is the weight diffrence.. i also have a 46la but i think i toasted that one back in my learning days.. so i really cant say anything bad about either.!!!

Thx guys. Im going to put the .46 FX in my dazzler.

You will be a lot more pleased with it.

Yup, depends on what you will use it for..... For a trainer, the LA is a good choice because it is simple, won't overpower, and seems to run forever. The FX costs more because it is designed for much higher performance and would be great for the Dazzler. Like all OS products, runs forever if taken care of.

fx is better...

The FX is definately the strong, quality, engine.
The LA is a very reliable, but weak engine. BUT if the LA is put in a plane like a light traniner it is a great combo. I built an LT-25 which weighs only 4.5 lbs. and put my old .40 LA in it. I fly low wings with Saitos but I will always have a trainer. I built this with almost no dihedral. I had 150 flights on that old engine in a "rebuilt-several-times" Superstar!! It was sluggish to say the least. Now in this LT-25, (63" span), I have near unlimited vertical!!!! ...lownslo..

The FX is a stronger motor.
I would go with it.
You may also want to look at the Tower BB engines.
They have had a very favorable review in the past.
