Upon reaching 4500ft altitude engine sound drops to just above idle while in climb. Rpm and manifold reading stay at full throttle setting, but there is noticeable power loss. Wep will not engage even though manifold and rpm is at max. Level flight will eventually restore engine rpm sound, but further attempts to climb give the same results.
At 8k altitude, rpm sound remains just above idle at level flight, and power is low as speed very slowly climbs towards 200mph. At 225mph enging rpm sound begins to climb again and acceleration returns to normal.
During this entire test, joystick throttle remained at full. Joystick was calibrated prior to flight. Using a Saitek Cyborg evo.
Also noticed there is no tempeture guage, so I'm wondering if the AH2 model is not finished.
Tested F4U-D for comparrison, there were no anomilies with this plane. Tempeture gauge is installed in the D model.
