This is AFTER they have been filled and painted, etc. and with everything connected ready for flight. A very technical answer, I'm sure you will agree! Now get goin' to that airport and fly!

Then weigh the cup and contents, and with the lengths of the associated moment arms, calculate exactly how much weight must be cut from the mass balance weights. This procedure is written up in detail at the URL listed below. Everything should be connected, ready for flight, including the trim tab link rod. Because of the system friction, you will need to tap the tailplane up, then down, to see how far it goes each way, to determine if you are in balance or not. http://terryseaver.home.comcast.net/N135TD_mods.htm Look at the section called "Tailplane mass balance procedure" Regards, Terry Seaver A135 / N135TD -----Original Message----- From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com] On Behalf Of Jim Butcher Subject: Europa-List: Tailplane Mass Balance --> Europa-List message posted by: "Jim Butcher" How does one go about balancing the tailplanes? I have the tailplanes with trim tabs in place. I have not connected the trim tabs to TS05 trim tab link rod. All the rest of the pitch control system is connected. I have installed Mod 70 but this is my initial attempt at balance. The weights are clear of pitch control stop structure and the new tuffnal strips from Mod 70. If I take both weights off TP18 the mass balance arm it swings up to its stop. However if I add the weights the tailplanes can be put in any position and stay there. Is the idea to add just enough weight so the tailplanes come to their neutral position aligned with the fuselage? I read a thread that referred to stick forces when displaced from neutral. Is this the way to set up the balance? Obviously there is something I don't understand. Can anyone shed some light?

I have used a Tab that fits under lip of access hole and is secured by a screw. I'll send photos.

I also reinforced the door as they have a tendency to flex slightly in flight.

I've already proven (in flight) the peripheral parts of a fuel system (pumps, filters, pressure regulator, return etc) that would serve the injection. Anyway, there would be no justification for the cost of retrofitting this system in terms of benefits and savings, unless a good price could be got for the parts removed (carbs etc). But then that's why I thought of you!
