I have (or will have, long story) a GFC500 in a 1965 M20C. I did not have the auto trim option installed. Does anyone have operational experience in a GFC500 install without the trim option? I assume I will get "trim up // trim down" messages and I would adjust the trim appropriately. How much of a PITA is that in operational practice?
The long story: I got the plane painted, then moved it to the avionics shop. The GFC500 install was completed short of the servos themselves, supply chain backorder and the shop placed the order late due to an oversight. I took delivery of the finished avionics install that included dual GI-275's, replacement comm2, and a EI CGR30 C&P combo engine monitor. All finished ... except for the GFC500 servos. This is the status now, I got to fly the plane for two weeks before departing on a one year deployment assignment to Korea, which is where I am now. The end result is I have yet to experience all that GFC500 goodness in MY plane, though I have used a GFC500 a fair bit in a Cirrus SR20, I know it's gonna be pretty cool.
I have the option of spending a few additional AMU's and go ahead and purchase the trim servo option, probably a quick and easy install, when I return from Korea and my bank account has a chance to get refilled with AMU's. Interested in pro's and con's of doing so? I mean, trimming by hand isn't that hard, right? I'm on the fence regarding ordering the trim option.
Thoughts?
