Practiced some 8's on Pylons in rather windy conditions (220 at 30kts) this weekend and had a terrible time. One thing that I noticed, as I turned to the upwind side, I really had to drop my altitude to keep the pylon. However, this big push on the nose really increased the RPM on the motor (I did the maneuver at about 2200 RPM in a C172M). In other words, my groundspeed was decreasing so my pivotal altitude was dropping so I had to descend. Due to the wind, the loss of groundspeed was so rapid that I really had to dive. This caused me to pick up speed again in the dive and the engine speeding up to 2500+ RPM. I was really fighting the maneuver the whole way. So to keep my altitude more stable, I began to pull back a touch of power as I pitched down to keep my airspeed more constant and again on the downwind side where I had to climb slightly I added a bit of thrust to maintain airspeed. When I was taught 8's on Pylons I was told not to touch the power because it will jack with your pivotal altitude but I'm wondering if in this case, due to the high winds is adjusting the power is warranted?
