    EGT issue

    I have a D180 in mt RV6A, been working fine for years. Suddenly yesterday all 4 EGTs read wrong. They all seem to read approximately the same value of 541degC, but there is a few degrees of jitter. They never read greater that 541degC. Normal cruise EGT reading has been in the 700 - 800 range...

    Sevo mechanical wear tolerance

    Hi, today I started the annual on my RV6A. I installed an autopilot in 2010, and have been enjoying it ever since. During the inspection today, I noticed some lateral slack on the roll servo output shaft. I didn't have a vernier with me to measure it, but I'm guessing there was about a 0.3mm...

    Autopilot NAV from Garmin GNC250XL

    I have recently installed a new panel on my RV6A including my old Garmin GNC250XL, and a D180 with all the autopilot gear including AP74 & HS34. I have connected the GNC250XL using ARINC429. The Garmin has 3 options for output on it's ARINC channel:- 1) Collins PL2; 2) King EFS 40/50; and 3) w/o...

    Ammeter sensor/shunt

    I am upgrading my aircraft to D180 with autopilot, I previously have had an early version of Vision Microsystems VM1000, which I am of course removing. However some or the sensors may still be usable. How about the current sensor supplied by Vision. It is a coil through the middle of which a...

    Flight Timer

    The D180 includes the usual timers, including "Flight Timer". The manual says this timer counts the time since powerup while the oil pressure is above 15psi (and it's true, this is what mine does). Why not instead the time while the Airspeed is reading anything above 0kts? This would be a...

    Coolant Temperature

    I have a Rotax 912ULS in my Foxbat aircraft, and since I wanted to use all 3 GP inputs on my D180, I have replaced the 2 resistive Rotax CHT sensors with J type thermocouples. I have used one of these Rotax CHT sensors as a coolant temperature sensor. My installation manual lists 4 types of...

    OAT Installation

    I am installing the Dynon 2 wire OAT probe to my FlightDek180. The manual informs me to use one of the GP inputs, but doesn't add any instruction about a pull-up resistor from the 5V excitation, as it does for other sensors connected to a GP input. Is this deliberate, or an oversight? Bo

    AOA Boom & static

    Hi there, I have bought the Pitot/AOA Boom and am in the process of working out a mount for it. I am replacing the existing combined pitot and static with this AOA boom, so I will need a static source. I was wondering if I could add a third pipe to the boom for static, and drill some holes in...

    Airspeed range

    I'm building an Aeroprakt Foxbat A22. I chose this (my second a/c, the first is an RV) for it's low speed ability. It has a quoted stall speed of 27 knots. I want to fit the flitedek D180, to save weight and maintain the low stall speed, but the spec sheet for the D180 shows the airspeed range...
