Sorry for the delay in reply, been out for a pint, or several.
In answer to the questions, NHN2 has nailed with the remarks about driving and filming. Peveril is very controllable indeed, but the new bijou F&St.M is a bit bendy and a good slug on the reg is required to move the loco from a standing start, especially on the corners, easing back rapidly thereafter, and with only two hands to do this and aim the camera some allowances have to be allowed for 8|
Running time is around half an hour, but the water runs out before the gas, so a top up or two is in order.
Otherwise Peveril is a real star performer, my only minor gripe, and I was fully aware of this before parting with any cash, and it didn't stop me, is that there is r/c on the reg only. A servo on the reverser would have been perfect, but no worries.
