I thought of this idea several years ago, but these engines being single stage do not have enough pressure for bleed air like the big boys... I considered a separate air tank with a servo or electronic valve to quick dump air into the retract system to blow the gear down and lock, but a lot hinges on the size if the leak you have if it will overcome the leak and have enough pressure to blow the gear down. It would be a one shot deal after you have determined you have no air it the retract system... Kinda a "Hail Mary" deal for sure.... Just what we need in the hobby... More drama !!!! I have been there myself... Hit the retract switch and all the sudden the " Disaster like Music " starts playing in my head [X(]... Just like in the movies !!!!!
