How are they doing the engine probes now?  Do you have electric start?  In

the past they had to put the probes in the position of the air start

nozzles.



The Blue Mountain has always seemed to have a lot of bang for the buck.



Thanks,  Jay

 Gang:

 

 As for my experience with Blue Mountain Avionics, it has been nothing but

 superior.  They have worked very hard with Barry and I on multiple issues with

 regard to doing 9-cylinder engine monitoring, installation, etc.  Your mileage

 may vary, but they have been fantastic to work with.  I called Dynon and GRT

 during my decision making process and asked about 9 cylinder monitoring and

 got a flat out no, not in the cards.

 

 With the Sport, I get a display I can actually read due to its size, synthetic

 vision, XM weather, full integration to the Garmin SL-30.  If you do the

 Garmin GTX 330 transponder, you can even have traffic.  In addition, I get

 full 9-cylinder engine monitoring, fuel flow, etc, etc.  There is also an

 aerobatic mode that minimizes info on the display to attitude, airspeed,

 altitude and g's.

 

 If I were doing it all over, I may even have considered their EFIS-2 as it

 gives you the 6-pack, HSI and moving map all in one display.  Very nice.

 

 More expensive that Dynon, yes.

When I was discussing CHT and EGT with BMA, they asked for Barry to ship them a cylinder from a Housai as there is not an electric start option for the Housai like there is for the M-14.  The engineers at BMA came up with a solution using the air start as the location to monitor CHT but kept the air start valve on the cylinder intact.  An engineer and the company president then flew out to California to monitor the installation of the CHT probes on my plane.  How's that for support!



We are now in the final stages of the tach solution for the Housai.  BMA installations typically use a Hall Sensor mounted on a magneto to feed their unit for rpm.  We looked at the magneto and the air start spider valve as possible locations for the Hall Sensor.  Both require some form of adapter to make it work.  We inquired about using the magneto p-lead.  BMA requested oscilloscope data from the p-lead to see if the signal is compatible with the tach input on their unit.  That data is being analyzed right now.



We anticipate getting the engine running by the end of the month or first week in September.  So we will have more data then.

PS - Good to see Alex is up to his typical excellence flying aerobatics.  Hope to see both of you at Waycross.  You will be able to see the BMA unit there.
