Tim,
I received and replied to your e-mail.
You hit the nail on the head, these planes are meant to fly with the throttle full forward. Don't try to fly them like a contemporary 2 meter aircraft. You will find the Vertigo to be even faster than the P-7 given the same power. Power it up with something good and you will have vertical power, speed and a locked on feel that won't get old any time soon.
