>It does matter.

Allow me to me rephrase, it doesn't matter if you want to fly single engine or more, larger or smaller rocket, scratch, kit or otherwise, all you need to do is determine the scale and the correct thrust to weight ratio regardless, and you can make any airframe successful to the degree you want it to be.

>Too many people try to do things the model wasn't designed for, and then blame the model for the issue.

Agree 100%.

Jerry is also correct, many people over build especially for low power.
