I just uploaded my version of the Curtiss Seahawk float plane to flightsim and simviation; should show tomorrow.
I created this FSX Acceleration project to have a companion for the SOC-3 Seagull which is also a catapult launch plane. I continue to use the rcbco-30 gauges for this purpose. I have a model of the P-6 catapult (on my version of the USS Idaho and other battleships) to which I added the Acceleration style catapult. Unfortunately, this is hard wired into the sim at 200 mph at 300 feet. I tried the SC-1 on it and it came off the catapult already very high and the nose almost straight up! Totally unrealistic for this vintage aircraft. One can adjust these values in the .cfg ini file for the rcbco-30 gauges. I set mine for 80 mph at 80 feet which gives the SC-1 a smooth straight out take off. Also works very nice for the SOC-3!.
I have added a few screenshots, including a birdseye view of the VC.
