I have kind of beat around the bush on a few other topics/threads, but I am about to pull the trigger on a bladder installation (M20J) and had a few remaining questions:
1) Other than a 36 lbs loss in useful load, what other draw backs are there? Some have mentioned linking pipes vibrating loose causing leaks. Others have mentioned the utility tape coming loose resulting in chafing leaks. Anything else?
2) I have the drawings, but not the full STC. What skin work is necessary for the new fuel caps? If, for some reason, I revert back to a wet wing some day, will I need to replace an entire skin?
3) For a 64 gallon mod, does the useable change? (61 gals)
4) Has anyone had any issues with the tank vent ice masts?
5) O&N estimated they sell 20 or more Mooney systems a year. I rarely see them (local, OSH, fly ins, Moonsyspace respondents). Who has them? How long have you had them? Any experiences?
Please know I value and appreciate any information or experiences you could provide. Drawing attached.
