Old Chub Posted January 29, 2019 Report Posted January 29, 2019 New Member here and this is my first time using so here goes. When installing a remote compass for the HSI in a pre J model Mooney where do installers usually mount the flux valve (Magnetic Azimuth Transmitter) Honeywell KMT 112? Thanks Old Chub Quote
ArtVandelay Posted January 29, 2019 Report Posted January 29, 2019 Mine is in the tail, on a shelf built for that purpose.Tom Quote
Old Chub Posted January 29, 2019 Author Report Posted January 29, 2019 I understand the gyro is mounted on the avionics shelf in the back but were is the flux valve. This item is approx 3 to 4 inches in diameter and appox 3 inches tall with a rounded cover.. Quote
Greg Ellis Posted January 29, 2019 Report Posted January 29, 2019 I just had an HSI installed and I think they put mine in the right wing quite a ways out towards the wing tip. I can check with my shop to be sure. Where in Fort Worth are you based. I fly a 63 C model out of Spinks (KFWS). Quote
KSMooniac Posted January 29, 2019 Report Posted January 29, 2019 I believe left wing was the factory location for J+ models. Less chance of interference in the wings (from antennas, motors, etc. ) but it needs some distance from a strobe power supply.Sent from my LG-US996 using Tapatalk Quote
jetdriven Posted January 29, 2019 Report Posted January 29, 2019 (edited) Right wing about 2/3rds out. I installed an KMT112 there for my Sandel Sn3308 install. Edited January 29, 2019 by jetdriven Quote

KSMooniac Posted January 29, 2019 Report Posted January 29, 2019 I'm not sure if speed brakes would potentially interfere or not...I'm sure the installation manual would have guidance.Sent from my LG-US996 using Tapatalk Quote
Yetti Posted January 30, 2019 Report Posted January 30, 2019 Goes in the center right above the dual framulator vents. 1 Quote
Ragsf15e Posted January 30, 2019 Report Posted January 30, 2019 I have a King HSI. Flux dome as you described is in the tail, maybe 2’ aft of my battery. Right next to my AP pitch servo. Perfect location. Roll servo is in my left wing. I hear right wing is a good place for one if your strobes are well grounded. Quote
carusoam Posted January 30, 2019 Report Posted January 30, 2019 Welcome aboard, Chub. Your question came up the other day as well. Complex questions can often take a week to get complete answers... The search function can cut a week out of your wait... In modern Mooneys with BK HSI... the electronic compass device is in the copilot wing about half way out... If you want to see where it is in other Mooneys... the access panel will have brass colored rivets holding the panel in place... Best regards, -a- Quote

Thanks Old Chub I asked the shop that did my install recently and this was their response: "Normally in an area away from electromagnetic interference, autopilot servos, antennas, speakers, power cables, flap motors, strobes, rotating beacons, so leaving outer sections of wings or tail as best choices."

Old Chub Posted January 31, 2019 Author Report Posted January 31, 2019 Thanks to all that replied. Great information. Jet Drive = I am installing the same thing. A Sandel 3308 Greg Ellis = I am at Hicks Airport. Just move over from GPM last week. My Cessna 120 is also there at Hicks. Quote

Old Chub Posted February 1, 2019 Author Report Posted February 1, 2019 Jetdriven, Thanks for the photos. as they say a picture can describe a thousand words. I will start working on a like bracket for the flux valve (not to be confused with the flux capacitor) Old Chub Quote
