It also controls the trim speed I believe.

Easy Cheap Dependable fix. 1) Replace your "Flap Toggle Switch" with a Double Pole (on) off on switch. (Same as original but Double Pole) 2) On the 2nd pole (not controlling your flaps) install a single pole double throw "Relay". Install the relay so when your flaps are in the -3degree position (Cruse position) the relay is activated. Any other position "Off" (On) climb out or landing configuration the relay will not be energized or normally closed. 3) Split the 14v power to both legs of the relay (Line side of the relay) "Normally open and normally closed legs of the relay". 4) On the "Normally Closed" (1st leg) pin on the relay (Load side of the relay) run your 14 volt power through the closed contacts, You now have full power to your trim motor. You will need full speed trim for takeoff and landing configurations. 5) On the 2nd leg of the relay (load side) the relay hook up a 9 volt 7809t voltage regulator with a capacitor. Connect the 9 volt wire to the 14v wire on the (LOAD SIDE OF THE RELAY) that connects back to your trim motor power. Now when you are in the -3 Degree cruse position the relay is activated. You are now feeding your trim motor with 9 volts and this will slow your trim motor down enough for "Fine Feathering". 6) So when your flap switch is in the Off or (ON) position your relay will be closed and feeding 14volts to the trim motor. When your flaps are in the ON position (Normal Cruse -3 degrees) your relay is active and switches the power to 9volts for your trim motor speed reduction. Works like a dream. Costs about $20. $10 for the Double Pole On Off (ON) toggle switch $5 for the 12v/14v relay (Fog light, horn, etc relay) Checker auto $3 for the voltage regulator Radio Shack or Fry's $2 for the capacitor Radio Shack or Fry's Optional computer fan 3 wire plug to plug the voltage regulator into for easy termination $.99.

In the set up, for example if you put TL=18, TH=06, LAS = 60, HAS = 170; Then the trim will run at speed 18 (almost max speed) when the airspeed is 60 or less; it will run at speed 6 (slow) at speeds of 170 knots or more; and in between it is linearly extrapolated (e.g., at 115 knots it runs at speed 12). IF YOU SET the speed to less than 4 the trim function is turned off. To access the manual function, just boot up the autopilot, set the altitude as normal, then push the right hand (vertical) function button. The display should say "manual trim". (If it doesn't, cycle thru the vertical functions by pushing the V button). Turn the rotary knob clockwise to trim up, counterclockwise to go down. Note: if you have multiple trim control switches (like the top hat plus the autopilot) then you need an isolation system (either a hard switch or relays) which allows the autopilot trim signal to go "straight thru". It uses pulse width modulation which is too high a frequency for a relay to follow. I built my own relay board using Digikey parts. Personally I love this system, I don't know why Trio doesn't advertise it more. I have never been able to smoothly trim in cruise with the top hat, just because of the force I put on the stick when trying to use the top hat. I have my autopilot near the top of the stack, but easily reached with my right hand. -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=414931#414931 ________________________________ Message 7 _____________________________________ Time: 11:23:50 AM PST US Subject: RV10-List: Re: RV 10 Aileron Trim easy fix... From: "Bob Turner" A few thoughts. I like to cruise with the flap switch in the off position, but your set up requires one to leave it in the up position. If the flap limit switch fails the flap motor will run continuously. If one desires to take off with no flaps (-3 reflex) he has to put the switch in the off position - opposite of cruise. My point is, there are operational choices to be made, so this is not too different from just putting in a dedicated trim speed switch. I found it difficult to slow the trim as much as I would like, using just lower voltages, without using voltages so low that the trim motor would stall. Since you've already got some electronics there, for just a few bucks more you could put in a pulse width modulation system and adjust it to go as slow as you like. -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=414938#414938 ________________________________ Message 8 _____________________________________ Time: 06:51:52 PM PST US From: "JimVillani" Subject: RE: RV10-List: Re: RV 10 Aileron Trim easy fix... You dont have a separate "Cut off switch" for flap motor? Put it in the Minus 3 position then turn it to off (center position) still works at full speed... It is On "top position" Off "Middle position" (On) "bottom position." It stalled because you didnt use a capacitor... And if the Pulse Modulator fails?.. I like the KISS plan... Keep it simple...
