Most model rockets blast off at a much higher acceleration rate than full size rockets. Is it possible to have model rockets take off slowly to more closely mimic the acceleration speed of full scale rockets?

Answer 1

The thrust-to-weight ratio for most model rockets is *waaaay* higher than the TWR of orbital rockets; mostly because mass scales exponentially with size but thrust doesn’t. You can get a similar visual effect by lowering the TWR on your model rocket to something close to that of an orbital rocket – by either reducing the thrust or increasing the weight (or probably both).
