I have flow the 4* out of grass and asphault, on grass you add power more slowly than on a hard runway but pretty much you can have it on full power and with the tail flying before you apply up elevator. Since most of our models are overpowered holding elevator on take off dont matter much because its all thrust, the problem arise when the engine quits and there isnt enough forward airspeed. Thats when I have seen many beginners eating it on take off. As far as tail dragger, everyone gets used to it quite quickly, a few minutes taxing your model and you get the hang of its handling characteristics. If you want better aerobatic performance later on, go with the 4*. If you want a faster and more aerobatic "trainer" then go with the midstar.
