| Subject: | RV6A First flight with new Elastomer NoseGear/Engine Mount and |
custom U00020A-250 link
Fellow RV-6A owners/builders,
Hopefully, I can claim to be the first RV6A builder/customer flying a
RV6A
with the new elastomer mount system. Installation required a shortened
version of the elastomer link which I assisted the Van=92s team in
developing
(sent to me as part number U00020A-250).
First flight with the new configuration was uneventful related to the
NoseGear/Engine Mount change. No issues with Taxi, Take-off, or
Landing.
The new elastomer system provides a smoother ride in my opinion from the
original stiff leg.
The shortened elastomer link still provided sufficient clearance for the
prop when the nose came down during the landing rollout.
The blockoff plates for the cowl slot to accommodate the NoseGearLeg
travel
were placed according to plans and did not exhibit evidence of contact
upon
inspection after the first landing.
The suggested cowl louvers were not installed for the first flight and
were
not shown to be necessary at this time based on a 90KIAS full-power
climbout
to 3500=92 MSL and another climbout to 4500=92MSL
FYI, my configuration is IO360B1F6, MTV12 three blade CS prop, LASAR
ignition, and AFP injection all under a SamJames cowl/plenum. The
Throttle
and Mixture cabling required customized mounting brackets to accommodate
the
engine mount / nosegearleg attachment structure.
There are a few points that need to be emphasized for other builders
making
this change:
1. The shortened U00020A-250 link is required to allow for a safe deck
angle for take-off and landing since the 6A has shorter mainger legs
than
the 7A/9A
2. The new engine mount moves the engine forward approximately =BE=94
depending on the manufacture date of the original mount being removed.
In
my case, this necessitated the installation of a new cowl to accommodate
the
shift.
3. The installation of the new mount requires emphasis and
concentration on the drilling of the lower center two mounting holes in
the
new mount. Centering of these two holes is required to be accurate as
tightening of the associated bolts requires the insertion of a =BD=94
socket
into the base of the mount.
I have provided some questions to the Van=92s team based on my
experience:
1. Will the U00020A-250 link become a standard option for 6A builders /
updaters?
2. Will the drilling of Engine-mount holes on the firewall be
standardized so that the engine-mounts can be pre-drilled?
Thanks to all assisting in making this configuration work for the 6A '
hopefully now, all 6A builders/owners have the option to convert to the
new
design.

Very interesting to hear of someone using this on something other
than a 7A or 9A. Did you use the 7A engine mount?

Brian,
The announcement documentation says 7A/9A and 'should fit' 6A. I used that as
a starting point. The 7A/9A mount is the only one - so yes, the is what I used.
My early original mount was made before they standardized on some distances - hence
the 3/4" shift.
