That has got to be probably the most grossly overpowered WW1 scale model that I have ever seen.

The flying speed and overall performance would be so totally out of scale that it would be sad to see.

ewalters4, welcome to the Universe and hopefully we can guide you in your quest for a scale like but still satisfying performance.

There's no reason at all why a model of this size or even a little bigger cannot be built to 16 oz or less and powered very succeffully with an 049 running a 7x3. But bear in mind that if you were trying to take off from grass then yes, things can get messy in a hurry. It's quite possible that you would need to handlaunch this sort of model. After all, to a 28 inch model the normal grass is a scale foot or more tall.

It's not just thrust to weight but also wing loading that determines what flies successfully and what is a dog.

But for my 1/2A tecaco model the weight is 19 oz, area is just a bit less than 300 and the engine with an 8x5 puts out 10 oz of static thrust. The climb is very much like what I would expect of a WW1 scale model. A bit lazy in other words.
