Jay:
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.
