The Question was (see above). Not what the weight is or which one has the best bearings ect. I still say Evolution wins and it will outlast your plane and several more if you take care of it..
Ahh, but you clipped off the most important part of the initial thread:
i've been looking at the tower trainer .40 kit and looks like a good kit, just wondering what would be a really good easy to use engine(like something that starts good)
Nobody has mentioned a bad engine in this thread, just engines that aren't right for project at hand. A trainer should be well balanced and the wing loading should be as light as possible for it to fly smoothly and gently.
I mentioned the Evo .36 as a good possibility. He wants a really good easy to use engine (like something that starts good) for a Tower Trainer .40. Since the title of his post mentions .40 to .50 sized engines in particular, in addition to the Evo .36 and the TT Pro .36 I mentioned the .40 LA, the GP-42, and I specifically recommended the Norvel AX-40 as a great choice for the Tower Trainer that would help balance the airframe.
I think the whole problem with this thread so far is that everyone read the title, "Good .40 to .50 sized engine" and then started throwing out engines without reading what he was going to use it for.
Insanemoondoggie's post about his Tower Trainer experience with the Evo .455 is very eye-opening. His description of flying overpowered trainers is excellent, and I find my Tower Trainer flying in a similar "jerky" fashion where the .46 FX engine is pulling the airframe around behind it rather than the plane flying on the wing like a trainer should. I've switched my .46 FX over to an 11x4 APC prop to try to slow it down to some degree.
A ball-bearing .36 or bushed .40 should pull a Tower Trainer around with plenty of power while smoothing it out and making it fly on the wing more. It would also make the plane much easier to balance rather than having to add weight or fly it nose heavy. I'm really surprised that Insanemoondoggie got a GS-40 to balance on a Tower Trainer, the muffler is very heavy and the engine weighs in at about 2oz. heavier than a .46 AX. I would think you'd need a roll of nickels taped to the tail to get a Tower Trainer .40 to balance with a 19 oz engine on the nose.
