I see by your profile you have a 10X. I have a GV-1 on my 10X as well. I have it setup so that I can turn it on and off with a switch. I can set the rpm with a knob and can adjust it from 1600 to 1850 rpm. It is setup so throttle hold disengages it as well, regardless of throttle or switch position. Email me and I'll send you my program setup.
Some basics. Yes you can fly inverted with a governor, as well as sideways, backwards, backwards inverted, etc. Iow, any way you want. If you can do it without a GV-1, you can do with a GV-1 only better. You keep the same linear pitch curves. You keep the same throttle curves. You'll need them if the GV-1 fails because by default it resorts to the throttle curve. I usually set my throttle curve so that if the governor fails there will be a distrinct change in rpm to let me know. I haven't had one fail so far though. And there's a couple of minor tricks you can do to make sure it doesn't. Also, if you engage it with a switch you should have your throttle curve fairly close to the set rpm because otherwise the GV-1 will lag and take a few seconds to lock in. You can still have the rpm shift if it disengages, just not a huge one. Have your engine running perfectly before you try to use a GV-1. A governor can mask a poorly tuned engine to some extent, such as a lean run. It can also make a bad situation worse. I was running a 61 very rich on the top end and with the GV-1 engaged pulled into a hard climb. The over rich engine bogged which made it slow down, which made the GV-1 think it needed open the throttle to keep up, which made the engine bog even more, and so on regardless of what I was doing on the throttle/collective stick. See where this is going? ALWAYS, leave a mode where the governor can be turned off while still in flight. I dropped back into normal mode in which the GV-1 was programmed to be off and allowed the engine to recover so I could land. And finally, test all posible switch, throttle, and mode conditions using the SW-CD screen on the GV-1 to make sure of when it's engaged and when it's not BEFORE you fly. I've seen people use a governor for the first time only to throw the throttle hold switch later on and find out the gv-1 wouldn't disengage in t-hold. Make sure it does what you think it's going to do before you run into surprises in the air. |
