Yup, way too much......

On this size airplane the max diam prop you want to use is 12" due to ground clearance.

The .46 might be just enough power to fly this plane and the resulting engine magagement may suit the engine as it's an ABC. You'll probably need to keep the revs up to hold altitude.

The engine weight is also a factor. OS states that a .46LA weighs 9.6oz whereas the 65LA weighs 18.87oz ( I know yours is TT, just a comparison..).

Since an ARF is pretty much built, the 9oz difference in weight will possibly show up as a tail heavy plane with the smaller engine.

Ideal characteristics in a trainer, tail heavy and underpowered!!


Comparing a Cub to a heavy plywood ARF trainer isn't really fair. I've got a Zephyr which has a 62" wing and that only has a .15 in it. But it's a very lightweight structure.

ARF trainers are very durable and therefore heavier for their size. Once it's up there though it will 'float' and fly on the wing. It just needs a bit more power to do it.
