    SV-XPNDR-261 generates 60V transient on power rail, blows mosfet in RV12 power module

    Good news. The good news is we have debugged all the issues so far. There could be more. It really bothers me that we find too many OEM wiring errors. The number of "wiring shop" errors from the supplier who we all know, in my experience is at least a couple per system now. And not hundreds...

    SV-XPNDR-261 generates 60V transient on power rail, blows mosfet in RV12 power module

    STOP PRESS So more to learn today :( I bench tested the Trig radio and it powers up, so it appears there is some other issue on the board. We tested 13.2v at the pins to the radio and transponder, but it appears there may be voltage but no load capacity perhaps. Perhaps the Transponder is fine...

    SV-XPNDR-261 generates 60V transient on power rail, blows mosfet in RV12 power module

    We have determined there is a blown transponder (can't communicate) and a blown Trig Radio....power pins now have good voltage after we repaired the board and put in a newer MOSFET and a 110ohm resistor and diode. So two blown up bits of gear. Not impressed.

    SV-XPNDR-261 generates 60V transient on power rail, blows mosfet in RV12 power module

    We can simply replace it with an FDD8880 but it will likely blow again just as you have experienced. Need some protection. We are going to bridge a 100 ohm resistor in series to the Gate with a Zenner to ground between the resistor and the gate. Lucky I have a great electronics tech handy. :)

    SV-XPNDR-261 generates 60V transient on power rail, blows mosfet in RV12 power module

    We have just had one blow. This is a VANS problem not Dynon. We will be contacting them tonight also.

    Skyview/garmin 175 vertical glidepath indication is off

    I have only ever seen HSI located GS but to be fair we have only recently had vertical guidance by GPS in Australia a short time. The HSI represents only what the Garmin outputs, and so far even the lowest grade LNAV+V has been spot on the approach profile every single timed we have done a lot...

    Chasing altitude

    Not a lot of helpful info from you. Like aircraft type, what settings you have. Post them up so we can comment. Are you running software at least in the V16 range? This is critical. Also, what servos? Are you on the inner most hole without going over centre ? Most applications will be the...

    Yaw Damper RV10

    I have done a few including my own RV10.They work fine. Set your fixed tab to give you a near neutral ball in level flight. Then set the following settings. Torque 100% Low speed sensitivity 3 High speed sensitivity 2 Rudder gain 2.5 Rudder rate 0.015 AY Gain 0.900

    Roll tracking - Track vs GSS

    I think this what I have currently, give them a try and see how it goes. Roll Settings; Torque 100% Sensitivity 16 Roll Gain 0.3 Bank Angle Limit 27 Pitch Settings (SV42T); Torque 100% Sensitivity 16-17 Pitch Gain 1.7 Altitude Gain 0.8 Pull rate 1.0 VSI gain 1.5 G Error Gain 1.2 G error limit...

    D10A discontinued?

    And that there says everything you need to know. Plus they are not getting out of that product space ;-) I wish I knew more......I know enough to know there is more. I am impatient too.

    My Highly Desired Features - Wish List for Dynon

    I am curious who these are. I only see Garmin, Avidyne and Bendix-King and BK dropped theirs for badged IFD's. Smaller GPS 'data' providers for the low cost ADS-B products are nowhere the same as a certified Navigator. I would love the answer to be "New product launches from Dynon" and it had a...

    Glidepath Pointer/Needle/Indicator

    I use it all the time.....It is plenty big enough and does exactly what it should. It is far easier to see than say a B744 or similar.

    Rpm jumping about and reading very high on take off

    100K resistor usually fixes it.

    My Highly Desired Features - Wish List for Dynon

    I would rather they do not develop an IFR GPS and stay in business, rather than risk it. I like the notion of it, but the task is way more than many understand, myself included.

    Another new feature suggestion- better LOP function

    I know what you think is happening and it is all explained here. Timing is not doing the job, your Bonanza with its IO470 is not as reactive (perception) as I assume your Lancair is. The dyno data is pretty constant.
