				I'm starting to work on installing my 912S on my 701 kit.  I have the new rear ring mount that ZAC introduced not too long ago.  I'm curious if there's anyone out there who has the rear ring type mount.
 
 Are there any 'gotchyas' I need to look out for while installing the engine?  I feel like I'm the guinea pig trying this new product.
 
 Thanks,
 
 Dan Ginty

				Dan:  I also have the new 701 912S ring mount.  The installation guide I 
 thought was very good.  The problems I had were waiting for back ordered 
 parts.  Also the guide ends at Section 7 and there doesn't appear to be 
 any help with the electrical wiring.  I do have Homebuilt helps video on 
 _Rotax 912 installation_ and _Electrical wiring 101_ which have been a 
 big help so far. 
 
 Does anyone have a recommendation for which battery I should buy?  Rotax 
 says is should be at least 18 AH.

				I would recommend a non venting battery.  I.E. Dry
 Cell, or gell cell.  Having worked on lead acid types
 while in the military let me tell you that aluminum
 and battery acid do not mix well.  Even though the
 batteries were vented to the outside of the aircraft
 somehow fumes would manage to creep into the battery
 compartment and cause corrosion.  When I started
 working on aircraft that had nicads it was a much
 easier task to keep the battery compartment corrosion
 free.

				The one major problem I ran into was with the water pump outlets.  If I am not mistaken as you are looking at the engine from the rear the lower left water pump outlet tube needs to have the 80 degree bend instead of the 45 degree bend.  This has been discussed previously on the board.
 
 A second concern I ran into was the radiator brackets.  After approximately 5 hours of running the engine - all prior to actual first flight - I had both radiator brackets break.
 
 I don't know if it has anything to do with the ring mount but I have a tachometer that is spastic - will read OK for awhile but all of a sudden start jumping all over the place.
 
 Just some observations from my installation of the 912S on the ring mount for the CH701.
