Hey Guys
Hoping for an answer from someone that has a 701 where the CG is in the aft
range. Zenith lists a limit of 10-18 in. aft of datum. Mine is a taildragger and
has a BRS mounted in the forward portion of the baggage compartment (basically
no baggage capacity left, unless it goes in the right seat). My CG is coming in
at 16-17 in. aft through most scenarios. The worst case one that I could work up
so far involved starting out with the 6 gal. header tank only being full and a
240# passenger to bring it up to 1100. Still right around 17 inches aft, but
when it runs out of gas the CG shifts to 17.9 aft. Just .1 ahead of the aft
design limit (don't see myself getting near this situation, but still was
playing with the numbers to see where it could get). Have any of you had
experience with a plane that is balancing to the rear of the limit. and what
performance problems might be expected. I am already aware that I will have to
be very sensitive about airspeed to avoid a departure or approach stall. Would
just like to hear if others have experienced any other downsides to an aft CG in
this airplane. Hoping that there is some cushion built into the design in this
area and performance at lower speeds isn't depreciated significantly. With some
major rework I can shave a couple more pounds out of the tailwheel assy. Other
than that I would have to ditch the BRS and really don't want to go there.
Thanks

Hello list members.
I have a question about the E1-1X steel bracket for the Rotax 912 on my
Zenith 701.
To attatch the bracket onto the engine, we need to drill two holes in the
bracket. On my drawing, the forward hole is located 15 mm from the front
edge and 55mm up from the E2-1X dynafocal brackets. Distance between the
holes is 213,5mm and the remaining measurement is 41,5 mm to the trailing
edge of the bracket.
I have a correction to this drawing that indicates the 15mm measurement is
now 20mm from leading edge, which makes the trailing measurement 36,5 mm.
Is this according to what you have as the correct figures??
I do not want to drill into this part until I know for sure.
I would also like to thank everone who responded to my inquire about the
flaperon handle. Your input was very helpful.
Best wishes,
Johann G.

Johann,
That bracket is the ONE part that survived my crash!! (just kidding... my
flapperon handle made it too!)
I measured my hole and the front one is 15mm from the front edge as you
describe.. was unaware of the new 20mm dimension.. but anyhow, cannot
imagine what difference it would make, tho I am sure there was a reason.
I can testify that at 15mm, the plane will fly for at least 2 hours, maybe
longer if you keep the throttle springs at their factory specification.
Jon
Havent heard from Zed out there.... hope those tornados are leaving him
alone!
