Tower Trainer 40 MKII ARF
#2
Never weighed mine, but I can tell you that the OS 46 LA hauls it around easy, and that is not a strong engine. It is a great trainer plane. I am not a beginner, but I love to fly this plane for pure relaxation. I like to zip around making circles about 10' off the deck. Since I got mine, at least three beginners got it at my club's field since they know it can last them quite awhile if they don't total it first. Jon

That is good news. The least powerful of my 40 size engines is more powerful than an OS 46LA. 
I have about 12 40 sized engines to choose from.

Be sure to put in some down thrust. I put some in mine and could use more. Since you will have more thrust due to a more powerful engine, you can use it too! If not, you will be flying at less than 1/2 throttle all the time. Jon

My Feedback: (7)
I had a OS .46 FX on this plane with an 11 x 6 prop. And it was too much power for my flying style. But I tamed it down some by using an 11 x 4 prop. I was going to put an 11 x 3 and then an 12.25 x 3.75 on it and give those combinations a try. But I sold the plane. The Lt40 costs more but it is in my opinion a much better trainer.
